Features1. FeaturesThe OpenCom 510 is a communications system for integrated voice and data communication.The most significant feature of this communications system is itsmodular structure. The OpenCom 510 is designed for installation in a 19" frame.The frame itself can be installed in a 19" wall-mounted enclosure or in a 19" floorstandingcabinet.The system provides a number of slots for the installation of modules. In a fullyconfigured system, the following modules will have been installed (and all slotswill be occupied): 2 power supply units,1 control module, 12 interface cards. By combining different interface cards, it ispossible to create configurations suited to the user’s specific communicationsrequirements. If, for example, a user requests DECT-capable U pn interfaces or additionalS 0 or a/b interfaces, one or more interface cards can be integrated withouthaving to exchange the entire system.Moreover, OpenCom 510 systems can be cascaded, which allows you to integratea higher number of modules, or networked in order to meet growing communicationsrequirements.The OpenCom 510 can be integrated into system environments with structuredcabling. All connections to a structured cabling patch panel can be made withstandard patch cables.The OpenCom 510 supports the following communications applications:■■■Telephony with system telephones, ISDN telephones and analogue terminals,Internet/intranet data communication, CTI applications, sub-system operationand system configuration using a standard web browserAdditional software packages for expanded telephony functions can be operatedand for making telephone functions more comfortable, e.g. the digitalvoicebox and voice portal systems OpenVoice and OpenAttendant.The “DoorLine” intercom system can be operated.TelephonyThe OpenCom 510 communications system is designed to be connected to anISDN basic access interface using the DSS1 protocol. Both multi-terminal access(point-to-multipoint) and system access (point-to-point) configurations are sup-9

Featuresported. The system can be configured to run both types of access in parallel. S 0and S 2M interface cards are available for connecting the system to the telecommunicationsnetwork. An S 0 interface card provides eight S 0 ports (switchable toeither internal or external connections). The S 2M interface card provides one ISDNS 2M interface for connecting the OpenCom 510 either to a primary multiplexinterface or to a second PBX (ISDN point-to-point connection). For an overview ofinterface cards, refer to Modules starting on page 65.The OpenCom 510 firmware is designed for a maximum of 600 users. For informationon system limitations, refer to Technical Data starting on page 211.The following can be connected to the OpenCom 510:■■■■■■Euro ISDN terminalsDeTeWe system telephonesOpenPhone 52 ISDN telephones (to the U pn port)DeTeWe RFP 22 base stationsDECT handsets (with RFP 22 connected to DECT-capable U pn port ofMS+UPN2-8 interface card)analogue terminalsS 0 interfaces must be operated with Euro ISDN terminals in accordance with theDSS1 protocol.U pn ports are suitable for connecting the OpenPhone range of DeTeWe systemtelephones. Furthermore, the DECT-capable U pn ports of the MS+UPN2-8 interfacecard can be used to connect RFP 22 base stations.Analogue ports are suitable for connecting standard analogue terminals.If your network provider supports the CNIP (Calling Name Identification Presentation)feature, the names of callers will be displayed in addition to the numberswhenever external calls are received. The OpenCom 510 supports the display ofthe name on system telephones. However, if you have created an entry in the telephonebook under the number of the caller, this entry will be displayed instead.10

FeaturesThe OpenCom 510 can be integrated into an existing local area network (LAN) andused as an Internet access router and mail client by all workstations in the LAN.The OpenCom 510 can be configured and programmed by means of a webbrowser (web console). This browser needs to be installed on a PC which is connectedto the system.The OpenCom 510 can be pre-configured at the service centre and remote-configuredfor service purposes.A COM port can be used to connect a PC for the purpose of transferring connectiondata.You can use the “DoorLine” intercom system to connect the OpenCom 510 to abuilding’s wiring system, which enables you to use door opener and doorbell functionsthrough the OpenCom 510.The OpenCom 510 enables you to use third-party CTI (Computer Telephony Integration)applications. This requires the installation of a TAPI driver (provided onthe system CD) on a Windows PC. The OpenCom 510 also features the integrateddialling wizard OpenCTI 50. Via the OpenCTI 50 users can call up and use telephonefunctions through their PCs without having to install a special TAPI driver.Further Telephony FeaturesThe OpenCom 510 can be used to run digital voicebox and voice portal systems.The configuration data and the recorded speech files (messages for, or left by, acaller) are stored on the OpenCom 510 CompactFlash card, which is installed onthe MC+1-3 central control module.For further information, refer to the “OpenVoice” and “OpenAttendant” userguides.You can optimise telephone communication with the help of team functions andthe call-queuing function.The “OpenCount” application, which requires a separate licence, can be used torecord and save connection data; these data can be analysed using a number ofindividually configurable filter criteria. For further information, refer to the webconsole online help.You can connect two OpenCom 510 systems (PBX cascading). Cascading is asimple way of increasing the number of terminals that can be connected.11

FeaturesAs your communication requirements grow, the OpenCom 510 can be networkedwith other telecommunications systems. The OpenCom 510 can then operate as asub-system or as a DECT server. It is also possible to create a telecommunicationssystem with several networked PBXs.Internet AccessFor the purpose of providing Internet access, PCs can be connected to theOpenCom 510 by means of the internal S 0 ports, and an entire LAN can be connectedby means of the Ethernet port. If Internet access is already available froman Internet service provider, the OpenCom 510 can be configured accordingly. TheOpenCom 510 can also be used for IP configuration if there is no IP-capable clientnetwork. An integrated DHCP server and a DNS server will take over IP addressadministration and name resolution for the client PCs.The OpenCom 510 enables all connected PCs to access the Internet using acommon IP address; only the common address will be visible outside the LAN.Network address translation (NAT) is used to change the IP addresses of the local(client) PCs into the IP address of the OpenCom 510. This prevents direct access tothe LAN’s client PCs and thus offers protection against attacks from the Internet.The OpenCom 510 offers further protection of the LAN in the form of customisablefilter lists (firewall function).Note: Also observe the notes in Useful Information on InternetAccess starting on page 112.DECT Data CommunicationPCs that are not connected to the OpenCom 510 via the internal S 0 ports or theEthernet interface can access the Internet if used in combination with theOpenPhone 27 DECT terminals. PCs in these configurations can also make full useof the Internet and e-mail features of the OpenCom 510.Data will then be transmitted via the internal data interface of the OpenPhone 27.The OpenPhone 27 must be connected to the serial port of the PC. The Internetcan be accessed directly via the remote data transfer (i.e. dial-up) network. TheOpenPhone 27 will establish a data connection with the OpenCom 510 via theDECT air interface. The Internet connection itself will be established either directlythrough an ISDN B-channel or indirectly through the internal RAS interface of theOpenCom 510. Indirect RAS access is preferable as it uses the routing function ofthe OpenCom 510 and thus benefits from the security features of shared Internetaccess.12

For informationon configuring the OpenPhone 27 data interface, please refer to theOpenCom 510 online help.E-MailThe OpenCom 510 offers an integrated e-mail function that supports the POP3,APOP or IMAP4 protocols used to query an Internet service provider for incomingmail. The OpenCom 510 can be configured to enable every member of staff toquery mail accounts. The OpenCom 510 fetches the incoming e-mail headers (subjects)and senders from the mail server at set intervals and forwards them to theuser’s system terminal.E-mail accounts for the sending e-mail can also can be configured for users. E-mails can then, for example, be sent directly from the OpenCTI 50 to other users.In addition, users who have had a voicebox configured for themselves, can letthemselves be notified of new voicebox messages via e-mail.Important events and errors are kept by the OpenCom 510 in an internal log book:the error store. To inform or alert the system administrators, entries in the log book(system messages) can be sent via e-mail.Voice over IP (VoIP)The OpenCom 510 supports the connection of VoIP terminals and thereby allowtelephony via the existing company network infrastructure. For this purpose,corded system terminals of the type “OpenPhone IP” are available. These deviceshave the same functionality and support the same features as the non-IP enabledsystem terminals “OpenPhone”. For users who wish to use PC supported telephony,the IP system terminals are also available as separate licensable softwarevariations (OpenSoftphone). You will find further information in the chapter Voiceover IP (VoIP) starting on page 115).Further Network FeaturesYou can enable staff to dial into the LAN by means of RAS access.In addition, you can configure a LAN-to-LAN link via ISDN. Two OpenCom 510systems can thus connect their LANs for on-demand dial-in (from both sides).A NET CAPI (driver software provided on the system CD-ROM) enables PCs withoutISDN cards to use ISDN functions.13

Factory SettingsTelephony Functions2. Factory SettingsThe OpenCom 510 is delivered with the following basic settings and activated features.We recommend that you configure the OpenCom 510 to meet your specificrequirements before putting it into operation (see Configuration starting onpage 91).Tip:Notes on the functions listed below can be found in theglossary (provided as a PDF file on the system CD).2.1 Telephony Functions■■■■The OpenCom 510 is pre-configured for use in Germany.Analogue terminals: The dialling mode (pulse dialling or DTMF) is detectedautomatically.Incoming external calls are signalled at all corded terminals connected to thesystem.The system PIN, which is used for remote-programmable call forwarding, forexample, is “0000”.2.2 AuthorisationsAuthorisations determine which functions can be used at the terminals connectedto the OpenCom 510. Authorisations are configured for so-called user groups;users and their terminals are allocated to these groups.Three user groups are preset: “Administrators”, “Standard” and “Guests”. “Administrators”have access to all functions of the OpenCom 510 and unrestricted configurationrights. Users in the “Guests” group cannot configure the OpenCom 510, arenot able to make external calls, and have only restricted use of the terminal functionsof the OpenCom 510. The “Standard” user group, because of its default settings,is well suited as a starting point for the creation of user groups for normalusers of the system (e.g. the staff members of a company).14

Factory SettingsAuthorisationsNote: When the OpenCom 510 is first put into operation, allconnected terminals are in the “Administrators” group until auser logs on to the web console.

When you have completed all the settings in the Configurator, you must savethe configuration (see also Saving and Loading the Configuration on page 100).2. Then select the Log-off command in the upper menu bar.9.2.5 PreconfigurationConfiguration of the OpenCom 510 can be prepared at your DeTeWe CustomerService Centre or by an authorised DeTeWe dealer. For this purpose, aOpenCom 510 installed here is programmed with the customer data (e.g. user96

Configuration Configuring the OpenCom 510data, call distribution schemes, cord-bound terminals). This data is stored and thenloaded into the OpenCom 510 at the customer’s site by a service technician.This prepared configuration must be completed at the customer’s site (LAN configurationand DECT terminals).For configuration of the OpenCom 510 Internet functions, first ask the responsiblesystem administrator for details of the customer’s LAN prerequisites.9.2.6 Offline ConfiguratorWith the aid of the offline configurator a configuration for the system can beissued and created on a Windows PC. Thereby most of the configuration points areavailable. Each system type of the product family and firmware version release 7.0or higher, has its own offline configurator; this is managed with the aid of a starterprogram. The starter program is included on the product CD. The operatingsystems Windows 2000 and XP are supported.You can find further information in the chapter PC Offline Configuration starting onpage 183.9.2.7 Remote ConfigurationThe OpenCom 510 configuration can also be altered or updated remotely by a customerservice centre or authorised dealer. This requires activation of internal RASaccess in the OpenCom 510 for the customer service centre/authorised dealer.Note: If one or more MSNs are entered on thePBX Configuration: System: Remote service menu page inthe Configurator and the Status option is activated, remoteconfiguration access is then activated when a data call fromone of the entered MSNs is registered.The customer service centre/authorised dealer can then log into theOpenCom 510 as an administrator:■■User name: “Administrator”Password: [administrator password]97

Configuration Configuring the OpenCom 510Note: If you do not wish to let the customer service centre/authorised dealer know the administrator password, you candefine a temporary password for remote configuration withat least five digits.Use the following code digit procedure on a standard terminal or a system telephoneto activate internal remote maintenance access for the service centre/authorised dealer:Remote configuration on (log-on with administrator password)H * 1 9 * Z (system PIN) #Remote configuration on (log-on with temporary password)H * 1 9 * Z (system PIN) * Z (temporary password) #Remote configuration offH # 1 9 #Activation is automatically cancelled 30 minutes after the last configurationactivity.Note: During remote configuration, the OpenCom 510 isblocked for RAS access by any further users.Please note: The system PIN is preset to “0000” and it is absolutely imperativethat the system administrator changes it to prevent undesirableremote maintenance.Using remote configuration, all OpenCom 510 settings (with the exception of thesystem PIN) can be edited or updated. New software versions of the OpenCom 510and the software for the connected system terminals and base stations can also beinstalled (see the SYS Configuration: Firmware menu in the Configurator).For security reasons, settings in the Configurator, Net Configuration should onlybe edited on site to avoid malfunctions or failures in the customer’s LAN (e.g. dueto IP address conflicts). Refer to the chapter entitled Configuration Examplesstarting on page 103, where interaction between the OpenCom 510 and a LAN isexplained.98

Configuration Configuring the OpenCom 510Forced logoff of another user by the administratorThe configuration of the system can always only be edited by one user. Working onthe configuration in parallel is not possible. This ensures that no configurationconflicts arise.If the user “Administrator” logs in and another user with administration rights isalready logged in, then the administrator can forcibly log the other user off inorder to configure. This functionality, for example can be used, when configuringremotely, when a user has forgotten to log out.In order to forcibly log a user off:1. The “Administrator” user logs on with the administration password.2. They open the Configurator.A message shows which user is currently configuring the system.3. The administrator clicks on the Take over config rights button.The other user can make no further modifications of the configuration.9.2.8 Codes for IP ConfigurationThe IP configuration of the OpenCom 510 is performed on the Web console in theConfigurator, in the NET Configuration: LAN menu.In the event that the IP configuration of the OpenCom 510 has to be changed andaccess via the Web console is not possible, you can also use a code digit procedureto change these basic settings. Entry can be made from an analogue telephone, anISDN telephone and from system telephones.Set IP addressH *182 Z (system PIN) *Z (www) * Z (xxx) * Z (yyy) * Z (zzz) #Set NET maskH *183 Z (system PIN) *Z (www) * Z (xxx) * Z (yyy) * Z (zzz) #99

The factory setting is“0000”.9.2.9 Saving and Loading the ConfigurationConfigurations are saved in a file archive and can be loaded to the OpenCom 510either locally from a connected configuration PC, or by remote configuration.The following configuration and customer data can be saved and loaded again:■■■■Telephony and network parametersUser dataTelephone book entriesLCR tablesFor further information, refer to the online help documentation under the topicSYS Configuration: Data backup.9.2.10 Receiving System Messages as E-MailImportant events and errors are kept by the OpenCom 510 in an internal log book:the error store. To inform or alert the system administrators, entries in the log book(system messages) can be sent via e-mail.In order not to notified of every error, the administrator can define correspondinglog filters (in the Configurator, the LOG Configuration: LOG Filter menu). Thesefilters define which errors (category, severity, number per time interval) should benotified.

Configuration Configuring the OpenCom 5109.2.13 Generating Your Own MoH FilesThe OpenCom 510 comes with an internal MoH file for Music on Hold. TheOpenCom 510 product CD contains a number of MoH files with different volumelevels, which you can load at a later time as necessary.The file format for non-resident Music on Hold is *.wav. You can also save your ownMoH in a *.wav file and load it into the OpenCom 510.If you have a Windows operating system, you can use the “Sound Recorder”program to generate your own MoH file. This program is usually located in theWindows directory called “Multimedia”.The MoH file must be coded with 8000 Hz, 8 bit mono in accordance with CCITT, A-Law. This coding is required for the OpenCom 510 and can be set in the “SoundRecorder” when you save the file under Format (CCITT, A-Law) and Attributes(8000 Hz, 8 bit mono). The maximum allowable size for a MoH file is 256 KB(approx. 32 sec. play time). If a larger file is loaded then this will be “truncated” andthereby will also only be played for 32 seconds. The MoH capacity can be subdividedin a maximum of 5 files. These files can be used for different companies orfor internal and external calls.Note: If you don't have the Sound Recorder program or theappropriate codec on your Windows operating system, youshould install these components from your Windows CD.Load your MoH file in the Web console's Configurator, in the SYS Configuration:Components menu.Note: When generating your own MoH file, you may incur afee for the use of non-resident melodies (e.g. a GEMA fee inGermany or MCPS fee in the UK). The MoH files that comewith your OpenCom 510 can be used free of charge.102

Configuration ExamplesOpenCom 510 in Computer Networks10. Configuration Examples10.1 OpenCom 510 in Computer NetworksOne of the outstanding features of the OpenCom 510 is the integration oftelephony and computer networks. Connect the OpenCom 510 via a computernetwork (LAN) with suitably configured workstations, and you can use its networkfeatures from these workstations. Using a Web browser you can access:■■■■the OpenCom 510 Configuratorcall charge administrationthe OpenCTI 50, with which telephone functions can be used on a PCthe OpenCom 510 central telephone book and your personal telephone bookas well as to the company telephone book (if the multi-company variant is activated).In addition, the OpenCom 510 can be used as an Internet access server. RAS accesscan also be implemented using the OpenCom 510, which enables the integrationof external staff in the LAN.In this chapter you will find several examples of configurations showing integrationof the OpenCom 510 in a LAN. Which example applies to your situationdepends on the size and properties of the existing or planned LAN infrastructure.Note: Several menu entries mentioned in this chapter areavailable only, if you switch on the Level: Expert in the toplevel dialogue of the Configurator.103

IP can be used togetherwith other protocols (e.g. NetBEUI, AppleTalk or IPX/SPX) on the same network.Every device participating in data transmission using IP requires a unique IPaddress. An IP address consists of four groups of digits from 0 to 255, each separatedby a full stop. The supplementary protocols DHCP and PPP automaticallyassign IP addresses to devices. Class C networks normally use IP addresses inwhich the first three numbers are the same and the last number is uniquelyassigned to a specific device in the LAN. On the Internet, unique addressesassigned by a special organisation created for this purpose are used. Within a LAN,you can use addresses which are not unique world-wide:IP Range Common Netmask Comment192.168.0.0-192.168.255.255255.255.255.0 256 smaller networks172.16.0.0-172.31.255.255 255.240.0.0 1 medium network10.0.0.0-10.255.255.255 255.0.0.0 1 large network104

Configuration ExamplesOpenCom 510 in a Serverless LANIP enables the establishment of connections via one or more intermediate stations.The decision whether to connect directly or indirectly to the partner devicedepends on the network mask. The network mask for a class C network is255.255.255.0. If the IP address of the partner device does not fit the networkmask, the connection is established via the default gateway. If a device knowsseveral data routes to different intermediate stations, one speaks of a router.The domain name system (DNS) resolves a plain text DNS name into an IP address.The DNS is a hierarchically structured database, distributed worldwide. A DNSserver can supply information on the names and IP addresses for which it isresponsible. For all other information, a DNS server contacts other DNS servers. Forthe establishment of every connection from the workstation, it is possible to giveeither an IP address, or a name that a DNS server resolves into an IP address.Note: For further explanations of technical terms, refer tothe Glossary on the CD supplied.10.3 OpenCom 510 in a Serverless LANIn a peer-to-peer network, the workstations are connected to one another vianetwork cables. In many networks, the cables run in the form of a star from acentral hub or switch. Such networks do not require special servers. This configurationexample is also valid for a LAN with a server using a protocol other than IP(e.g. AppleTalk or IPX/SPX).ISP(DNS)OpenCom(DHCP, RAS,int.

All IP settings necessary for the workstations are assigned by105

Configuration ExamplesOpenCom 510 in a Serverless LANthe OpenCom 510 via DHCP (dynamic host configuration protocol). In this operatingmode, an IP address space reserved for such networks is used:192.168.99.254 OpenCom 510 IP address255.255.255.0 Network mask (class C network)192.168.99.254 DNS server IP address192.168.99.254 Default gateway IP addressInstall the IP network protocol and a Web browser for every workstation which isto have access to the OpenCom 510 network features.10.3.1 DNS Name ResolutionIn a serverless LAN, the internal DNS name resolution is performed by theOpenCom 510. If you type the string “host.domain” into your browser, a DNSrequest is sent to the OpenCom 510 IP address. The OpenCom 510 responds withthe correct IP address, so that the Configurator home page can be called up.In a peer-to-peer network (Windows network), the workstations each have a namewhich is displayed in the network environment. These NetBIOS names can differfrom the DNS names assigned to the workstations by the OpenCom 510. TheOpenCom 510 is not visible in the network environment.10.3.2 Internet AccessIf access to an ISP has been configured on the OpenCom 510, the OpenCom 510can be operated as an Internet access server without any additional configurationof the workstations. When you want to see a Web page, you simply type the URL(uniform resource locator; Internet address; “http://...”) in your browser. In aserverless LAN, the OpenCom 510 is configured as a DNS server and defaultgateway. The workstation therefore sends its Internet connection request to theOpenCom 510.In almost all cases, the request will contain a DNS name which is unknown in theinternal network. When you type a URL into your browser, the OpenCom 510receives the request to find the corresponding IP address. If the name is unknownin the LAN, the request is forwarded to an ISP’s external DNS server.106

Configuration ExamplesOpenCom 510 in a Serverless LAN10.3.3 RAS AccessNote: Workstation PCs automatically add a domain name toURLs without a dot. You specify this domain name in theConfigurator. For example, if you have configured“firm.co.uk” as the domain name, an access request for“www.firm.co.uk” will be interpreted as a local DNS requestwhich does not lead to the establishment of an Internet connection.For this reason, you should choose a name which isnot used in the Internet as the domain name (“firm-opencom.co.uk”for example).You can establish a connection to the OpenCom 510 from an external PC via anISDN card.The necessary IP settings are transmitted by the OpenCom 510 on establishmentof the connection. The computer that has dialled in has access to all services in theLAN that can be used via the IP protocol. The authorisation for RAS access is set upin the Configurator via the User Manager: User Groups menu.The technical properties of the connection can be configured in the Configuratorvia the NET Configuration: RAS menu. Further information can be found in theonline help of the web console.In a serverless LAN, Windows uses the NetBIOS protocol for accessing files andprinters via the network environment. NetBIOS can use NetBEUI, IPX/SPX or IP asthe transport protocol. In the network environment, you can only access files andprinters on workstations using IP for NetBIOS.107

Configuration ExamplesOpenCom 510 in a LAN with an IP-enabled Server10.4 OpenCom 510 in a LAN with an IP-enabledServerIn a LAN with an IP-enabled server, you should coordinate integration of theOpenCom 510 with the responsible network administrator. You must decide onthe IP address space to be used and which network services (DHCP, DNS, RAS,Internet access) the OpenCom 510 is to handle in the LAN.ISP(DNS)OpenComServer(DHCP, RAS,int. DNS,Internet)S 0S 0NetS 0 intS 0NetExt.PCPC 1S 0 NetHubPC 2NetThe OpenCom 510 in a LAN with an IP-enabled serverIn many cases, an IP-enabled server configures the IP settings via DHCP for allworkstations. On starting, the OpenCom 510 requests IP settings via DHCP. If thisrequest is responded to, the OpenCom 510 uses the IP settings received. You canthen use a workstation to access the OpenCom 510 Configurator under the IPaddress assigned by the server.In networks in which the IP settings are made manually, you have to enter the correspondingIP settings in the OpenCom 510 Configurator (NET Configuration:LAN menu). Here the OpenCom 510 acts as the DHCP server. A workstationrequesting the IP settings via DHCP then receives the settings you made in theConfigurator.10.4.1 DNS Name ResolutionIn a LAN with an IP-enabled server, the latter is also responsible for DNS name resolution.If you want to start the Configurator by entering a DNS name, you mustlink this name on the server with the IP address used by the OpenCom 510. Forfurther information, refer to the server documentation.108

Configuration ExamplesOpenCom 510 in a LAN with an IP-enabled Server10.4.2 Internet AccessNote: To access the OpenCom 510 under the same IP addressafter a restart, you must specify this IP address permanentlyon a DHCP server. On a DHCP server it is possible tolink the MAC address of a network card with a specific IP address.You will find details in the server documentation.You can also use the OpenCom 510 as an Internet access server in a LAN with anIP-enabled server. To do this, you must enter the OpenCom 510 IP address on theserver as the default gateway. In addition, you must edit the internal DNS serverconfiguration so that the resolution of external DNS names is forwarded to theOpenCom 510.In this example, the Internet connection is established from a workstation via theserver, which in turn requests Internet access from the OpenCom 510.There are two different ways of suitably configuring the internal DNS server. Youcan enter the OpenCom 510 IP address as a DNS forwarder. If you require access toextended DNS information, you can also configure the DNS server for a recursiveDNS request without the DNS forwarder.

If you additionally want to allow fileor printer access in the network, you must set up a suitable user account on theaddressed server for network log-in. If you use the same log-in name for theOpenCom 510 user account and the same password for the network log-in, youhave to enter this combination only once when dialling in.Note: In a larger Windows network with several segments,the lists of computer names visible in the network environmentcan no longer be established by broadcasts. In this caseyou use a special WINS server whose address theOpenCom 510 does not make known to the workstationwhen dialling in with ISDN. For this reason, you enter the addressof a WINS server manually in the network settings ofthe workstation.110

Configuration ExamplesBranch Link10.5 Branch LinkYou can use the OpenCom 510 to interlink two LANs via ISDN.To do this, you configure two OpenCom 510 systems so that they can dial in toeach other.In order for this to work, the two LANs must be configured for different IP addressranges (subnetworks). For at least one of the OpenCom 510 systems, change theprescribed address range for the LAN.OpenCom(IP=192.168.99.254,Net=192.168.99.0)OpenCom(IP=192.168.11.254,Net=192.168.11.0)NetS 0S 0NetPC 1PC 2PC 1PC 2NetHubNetNetHubNetThe OpenCom 510 in a LAN-to-LAN linkIn the Configurator, NET Configuration: Branch menu you can configure thedial-in settings. The OpenCom 510 will set up a connection whenever a IP datatransfer to the other LAN is requested.Note that such a connection is only set up when specific requests are made. Thesecan be for FTP file transfers, e-mails or downloading Web pages. Name resolutionvia broadcasts is not possible. If you wish to use the LAN-to-LAN link to access filesand printers in the Windows network, you need an IP-enabled server that administersthe name resolution for the Windows network.As the IP address range, you can select one of the 256 class C subnetworksdesigned for local LANs. Select a class C sub-network in the range from 192.168.0.0to 192.168.255.0.111

Configuration ExamplesUseful Information on Internet Access10.6 Useful Information on Internet Access10.6.1 CostsThe OpenCom 510 uses a router function to access the Internet, which means thatit automatically establishes an Internet connection when required and terminatesthe connection after a certain period of time if no data are being transmitted.Unfortunately, programs other than those typically intended to access the Internet(such as your browser or your e-mail software) may send out data packets whichcause an Internet connection to be established, even if these programs are notstrictly Internet-associated applications.Examples of such programs are the Microsoft TM XP TM operating system, variousmultimedia programs such as Realplayer TM and anti-virus applications that mayestablish an Internet connection for automatic updates (the so-called “phonehome function”).It is therefore highly advisable to limit ISP access by specifying the maximummonthly connection time under Connection time per month (maximal) in theNET Configuration: WAN: [Provider] menu on the web console.10.6.2 Using the WebA Web browser not only enables you to use the OpenCom 510 Configurator fromevery workstation but also to obtain a wealth of information from the Internet.Simply enter the desired URL in the address field of the browser. Access from astand-alone PC via an online service differs from Internet access via theOpenCom 510 in the following respects:■■■When you request a Web page, dialling in results automatically. There is nodisplay of dialogues with manual confirmation of dialling in or hanging up.Requesting Web pages is not a connection-orientated service. When the Webpage has been loaded completely, the TCP/IP connection is cleared. If you donot request further Web pages, the OpenCom 510 automatically releases theconnection to the Internet after a certain, specifiable duration.It is possible to call up Web pages simultaneously from several workstations.112

Configuration ExamplesUseful Information on Internet Access■The OpenCom 510 can block access to certain Web pages by means of filterlists.10.6.3 E-mailOne of the most important services in the Internet is e-mail. E-mails are buffered inindividual e-mail accounts on a mail server. Mail servers are operated by ISPs forexample. With the OpenCom 510 you can set up one or more e-mail accounts forevery user account configured on the OpenCom 510. These e-mail accounts arethen checked at regular intervals.If there are new e-mails in an e-mail account, and the OpenCom 510 has been configuredfor this function, the user specified in the OpenCom 510 user account isnotified of the new e-mail on his system terminal. OpenPhone 6x/OpenPhone 7xand OpenPhone 2x system terminals can also display information such as thesender or the subject of the e-mail.10.6.4 NATNetwork address translation (NAT) is activated on accessing the Internet (ISP). Yourequire this feature in order to translate internal IP addresses to valid external IPaddresses. This has three important consequences for Internet access:■■■Several workstations can share a single Internet access. You do not require aLAN access, only a single account with the Internet service provider.The IP addresses used in the LAN are translated into IP addresses validworldwide. So you require no such addresses for your LAN.Only IP connections triggered from a workstation can be established. Consequently,while you can call up Web pages from a workstation, you cannotinstall a Web server visible in the Internet on a workstation.Certain protocols cannot be used when NAT is being used. This affects protocolswith the following properties:■■IP addresses are transported in the useful load, e.g. NetBIOS over IP or SIP.The protocol requires an active, inward-directed connection establishment,e.g. ICQ.113

Configuration ExamplesUseful Information on Internet Access■The protocol will function without TCP/UDP port numbers, e.g. ICMP or IGMP.The OpenCom 510 NAT has suitable processes for ensuring the functions of manyimportant protocols affected by these rules. These are the protocols FTP (in“active” mode), CuSeeMe (“videoconferencing”), IRC (“chat”), ICMP errors(“traceroute”) and ICMP echo (“ping”).Depending on the internet telephony protocol (VoIP, SIP) the required NATextension (“Full Cone NAT”) or RTP-Proxy is activated on the Media Gateway Card.Protocols which require inward-directed connection establishment can be configuredin the Net Configuration: Port Access menu. For further information,refer to the online help of this menu.114

Voice over IP (VoIP)11. Voice over IP (VoIP)The term “Voice over IP” describes the usage of IP-based data networks fortelephony. It is possible to distinguish between two different types of VoIP:■■Telephony via Internet provides cheaper charge-models for telephone services.For telephony directly via the Internet, only the cost of data transmission isincurred. Various Gateway providers can provide crossover into the PSTN(“Public Switched Telephone Network”) for a fee. As well as standardised protocolssuch as SIP and H.323, proprietary protocols such as the Skype network,are used. optimised for data communication Voice and service quality viaInternet, is often indeterminable because you are dependent on the routes ofvarious service providers. which have been optimised for data communicationTelephony via Intranet enables joint usage of existing infrastructure fortelephony and for data communication. Integrating the two communicationnetworks into a single communications network can provide considerablesavings. The OpenCom 510 gives users all the features of system telephonythrough its use of an IP-based protocol. The control of the data connectionsused makes it possible to define exactly the voice and service quality.Telephony over the Internet using the OpenCom 510 provides you with the followingoptions (see also SIP Telephony starting on page 124):■■■■You can use low-cost “SIP trunk lines” with your existing Internet connectionYou can use the services of a SIP gateway service provider to access the publictelephone network (PSTN)Automatic fallback (bundle overflow) to ISDN connections in case of thebreakdown or over-occupancy of the SIP connectionWith a M100-AT4 interface card (4 analogue trunk lines) you can also use theexternal IP Gateway 1 for SIP telephonyVoIP system telephony with the OpenCom 510 offers the following possibilities:■■Use of IP-based system telephones connected to Cat5 twisted-pair ethernetcablesUse of IP-based system telephones via VPN, RAS, Branch or WLAN connections115

Voice over IP (VoIP)Fundamentals■■■■Using voice-data compression with compressing codecs, it is also possible tomake multiple IP-based telephone calls simultaneously on a 64 kilobit/s ISDNlineUse of PC-supported system telephones (so-called “Softphones”) without extrahardware costsTC system networking using Q.SIG-IP via VPN connections (see also PBX Networkingstarting on page 151)Setting up a “DECT over IP” network lets you use existing Ethernet cabling toset up a DECT network. The special DECT base stations designed for thispurpose, can be handled using OpenCom 100’s Web interface (see DECTnetIPstarting on page 134).Integrating voice and data communication within the Intranet can provide savingspossible and a range of new possibilities. However joint usage of existing networkinfrastructure may also cause conflicts, with IP address configuration via DHCP forexample (for details see Start Procedure starting on page 129). You shouldtherefore always plan the use of VoIP in the Intranet together with your networkadministrator. This chapter will help you avoid possible problems.11.1 FundamentalsVoIP makes the transmission of voice and telephony signalling via IP (“InternetProtocol”) possible. After a connection is established, the terminal collects voicedata (PCM data), which is then sent to the receiver using an IP packet. PCM datacan also be compressed to save bandwidth.11.1.1 Propagation Delay and BandwidthIP-based data networks are generally not able to guarantee a specific minimumbandwidth and defined propagation delay. A synchronised 64 kilobit/s ISDN lineguarantees a fixed data rate as long as the connection exists. In an IP-based datanetwork, the data rate and propagation delay can vary. Short-term bottlenecks orretransmission due to errors may be the cause. A data flow interruption of a fewseconds is barely noticeable when fetching a Web page, but it can be seriouslyinterfere with a telephone call.116

Voice over IP (VoIP)FundamentalsA modern Intranet normally offers enough performance reserves and reliability tomake good-quality VoIP telephony possible. Specific components can also beoptimised; for example by using a modern switch which evaluates the TOS byte ofIP packets or by replacing unreliable connections.11.1.2 Latency and Packet LengthFor technical reasons, there is always a delay (“latency”) between the recording ofvoice data via the microphone and playback via the receiver. Voice data isrecorded for a short period so that it can be sent in an IP packet. The IP packet alsohas a signal-propagation delay before the receiver can begin playback. For thesereasons, the extra time required for voice-data encoding and decoding may beneglected.An IP packet consists of protocol data and user data. Sending shorter voice-datapackets causes the ratio between the user data and the protocol data to becomeunfavourable and increases the bandwidth required. Sending longer voice-datapackets increases latency.The length of the voice-data packets must therefore be adjusted to the requirementsof the transmission medium. Shorter voice-data packets can be sent if adirect ethernet connection exists. If an 64 kilobit/s ISDN line is to be used for transmission,then longer voice-data packets should be used.Longer voice data packages are generally used for SIP telephony over the Internet.The following table provides an overview of the required bandwidth for a telephoneconnection with various parameter settings. The values apply to halfduplexethernet; for full-duplex the values can be halved.Required bandwidth (kilobit/s) with respect to Packet Length and CodecPacketLength (ms)G.711 (notcompressed)G.729Ac. 6.3 kilobit/sG.723.16.3 kilobit/s20 180.8 68.830 51.2 48.0 45.940 42.450 37.12G.723.15.3 kilobit/s117

It is possible to optimisevoice-data transmission on an existing network using the available configurationsettings. Measuring the network quality may also help.The following comparison provides a guide to voice quality with specific qualitylevels:Quality Levels for Voice Transmission with VoIPG.723.16.3 kilobit/sLevel Voice Comprehensibility Comparable to1 Very Good ISDN2 Good DECT3 Satisfactory GSM4 Limited Defective GSM> 4 Unacceptable No ConnectionG.723.15.3 kilobit/sWhen a call is set up, the terminals involved negotiate the voice-data compression(“codec”) that will be used. This is the first factor that determines the achievablequality level:■G.711 A-Law (Level 1, uncompressed): The audio data of a PCM channel(64 kilobit/s) is adopted one-to-one. Every VoIP terminal must support thiscodec. This codec can not be used with an ISDN data connection.118

The duration ofthe recording and not the data packet’s byte count is relevant in making thisselection:■■■Duration 60 ms: two quality-levels depreciationThe achievable voice quality also depends on the packet propagation delay andthe packet loss between the terminals involved. These parameters can be determinedusing the “ping” program.Note: Measurements made with “ping” are round-trip propagationdelays.

Voice over IP (VoIP)Fundamentals11.1.4 OptimisationIf you detect a large fluctuation in the propagation delay during measurement,this may also cause the voice quality to deteriorate. This may indicate a defectiveor overloaded line caused by bit-error or collision correction resulting fromretransmission by the transmission procedure.An existing star-topology ethernet-network may uses a Hub as the central distributorof ethernet packets. A Hub repeats all ethernet packets received on allconnected lines. This can cause substantial collisions and result in a high fluctuationin the propagation delay.If this is the case, use a modern switch component. Selective forwarding of ethernetpackets (“Layer 2 switching”) avoids collisions. Modern switch componentsalso evaluate the TOS byte of IP packets, thereby providing the optimal prerequisitesfor VoIP telephony.11.1.5 Call set-upNote: The OpenCom 510 uses a TOS byte (“Type of Service”)value of 0xB8 for IP packets with VoIP data. This requests“Minimise Delay” and “Maximise Throughput” for IP packetsmarked with this value.Various IP-based protocols are used for system telephony via the Internet protocol(“IP”) (see also Start Procedure starting on page 129). Multiple TCP connections aremade between an IP telephone and OpenCom 510 for the telephone’s start procedure,registration and signalling.Call data is directly exchanged between IP telephones using the RTP (“RealtimeTransport Protocol”) protocol.Channels on a Media Gateway (MGW) are allocated for making a telephone connectionwith an ordinary terminal or for dial tones. The MGW converts IP voicedata into PCM data streams used with conventional telephony and vice versa. Forthis, IP voice data are exchanged between the IP telephone and the gateway.Tip:Switching between voice data channels may cause a slightdelay in some circumstances. For example: when accepting acall on an IP telephone, headset users should wait about onesecond before answering.120

Voice over IP (VoIP)Media Gateway (MGW)11.1.6 Useful servicesThe type of data compression used for VoIP prevents these types of connectionsfrom using certain services. Take these notes into account especially if you want touse connections made via Q.SIG-IP or SIP:■■■■ISDN data services can not be usedFaxes can only be sent using the uncompressed G.711 codecDTMF dial tones are only received by the other party if the uncompressedG.711 codec is usedAnalogue modems can not be usedTip:Configure the actual usage for the a/b ports, e.g. set them toFax or Data (analogue). Connections from and to these a/bports will then be made using uncompressed or ISDN connectionswhere possible.11.2 Media Gateway (MGW)The Media Gateway transforms VoIP voice data into PCM audio data. This functionconverts voice data between VoIP telephones and all other terminal types.Without the Media Gateway, VoIP telephones can only exchange call data directlywith other VoIP telephones. Media Gateway functionality is also required for producingdial tones and making external phone calls with a VoIP telephone. A Mediagateway card makes 8 channels available. One Media gateway channel should beavailable for a maximum of 3 VoIP terminals.The Media Gateway also takes over the routing function for external SIP connections,making 8 external SIP connections possible.Using the OpenCom 510, the Media Gateway is provided using at least oneMG+ETH1-1 interface card.121

Voice over IP (VoIP)Media Gateway (MGW)11.2.1 MG+ETH1-1Field of ApplicationThe MG+ETH1-1 interface card provides 16 Media Gateway channels for VoIP.The MG+ETH1-1 interface card can be installed in any of the OpenCom 510’s slots(1 to 12, see also the chapter Slots starting on page 27). Up to four MG+ETH1-1interface cards can be operated.Technical Data■ OpenCom 510 can be connected to the LAN via the ethernet port (10/100 Mbit/s).■■■■The interface card supports: all codecs used by VoIP telephones, silencedetection, echo suppression and DTMF tone detection.The interface card can not be used in a slave system.The interface card acquires its software from the system. After the card hasbeen installed it will automatically load the required software.No settings need to be made on the interface card.Pin AssignmentThe ethernet port’s pin assignment is designed for a direct connection, via a RJ45patch cable, to an ethernet Switch. You will need a cross-link cable (“Cross-overCable”) for connection to a PC.IndicatorsThere are four LEDs on the front of the MG+ETH1-1 interface card.122

Voice over IP (VoIP)Media Gateway (MGW)MG+ETH1-11234ETHMG+ETH1-1: LEDsThe LEDs have the following meaning:LED 1: Constantly yellow At least one call is being conducted via the interfacecard.LED 2: Constantly green The interface card is operational; the slot hasbeen activated (flickering is normal).Flashing yellow The interface card is ready, but the slot has notbeen activated or the interface card has not yetbeen configured.Constantly red New software is being loaded onto the interfacecard. If the LED lights up red for an extended periodof time, there may be a fault.LED 3: – Not used.LED 4: Constantly green An ethernet connection is available.Operational InformationThe MG+ETH1-1 interface card can be exchanged during operation; the systemdoes not need to be shut down or powered down. The slot must first be disabledin the Configurator in the Web console (see also Installing Interface Cards startingon page 31).Each MG+ETH1-1 interface card requires its own IP address. This can either beassigned statically or obtained via DHCP.1. In the Configurator, open the PBX Configuration: Ports: Slots page.2. Click on the slot number in the table row containing the desired interface card.123

Voice over IP (VoIP)SIP Telephony3. Enter the desired IP address in the IP address configured field. Enter “0.0.0.0”to obtain an IP address via DHCP.4. Confirm with Apply.The configuration page displays the MG+ETH1-1 interface card’s MAC address. Youwill need this for the static assignment of an IP address via a DHCP server.11.3 SIP TelephonyThe SIP Internet (Session Initiation Protocol) protocol provides you with a low-cost,standardised option for telephoning via the Internet. OpenCom 510 enables youto use external SIP telephone connections (SIP trunk lines). The PBX Configuration:Trunks: Route menu gives you the option of making an SIP connection ona normal ISDN line in case of bundle overflow, breakdown or over-occupancy. Youcan also set up your system to route certain types of calls, such as internationalcalls, to an SIP connection.Note: You will need a Media Gateway card for SIP telephony.You will also need a fast Internet connection such as DSL for SIP telephony.You will also usually need the services of a SIP provider. A SIP provider operates aspecial server (the SIP Registrar) to handle connections. The SIP provider alsooperates a gateway to the ordinary telephone network which users pay to use andwhich enables the SIP provider to provide calls to the telephone network.A SIPconnection can also accept incoming calls from the telephone network.The same voice transmission techniques as those explained in Fundamentalsstarting on page 116 are used for SIP telephony. SIP telephony has the followingdistinctive features:■■Subscribers are identified through an e-mail-like “SIP ID” such as12345@domain.net or name@sip-provider.com.SIP transmits dialling numbers always in a single data package (block dialling).Dialling can therefore be concluded with the hash key #on the system terminal,or the end of the number will be indicated by a time-out. The value forthis time-out can be defined for each SIP provider separately.124

Voice over IP (VoIP)SIP Telephony■■■■■■■■You must log on (“Login”) to the SIP registrar before you can use SIP telephony.Use the OpenCom 510 to manage important information for the registration(user name and password) of one or more SIP accounts. It is possible to makeseveral calls simultaneously using a single SIP account.A SIP connection causes constant Internet data traffic, so do not use SIP withInternet access which is paid for according to the time used.RTP call data is also exchanged directly between terminals for SIP telephony, sodifferent codecs can be used for sending and for receiving. It is also possible tochange codecs dynamically during a call. You should use every codec availablein the VoIP profile at least once, because this will enable you to establish connectionswith as many SIP subscribers as possible.Fairly large packet lengths are quite normal on the Internet. They compensatefor the longer packet propagation delay.A bidirectional RTP data stream with a dynamically-assigned UDP port numberis used to set up calls between subscribers. For this reason, incomng RTP callsoften fail to get past the Firewall or NAT configuration of the Internet gatewayproduct used. Do not use OpenCom 510 as an Internet gateway if the productused is to be compatible with SIP telephony. These products provide a “FullCone NAT” setting for this application.To enable the use of multiple devices on a single Internet connection, the IPaddresses used in a LAN (often 192.168.x.x) are translated to a valid IP addressusing address translation (NAT - Network Address Translation), but no statusinformation is available for NAT on an incoming RTP connection.To avoid thisproblem, the IP address of a workplace computer or telephone visible on theInternet is determined using a STUN server (STUN: Simple Traversal of UDP overNAT). You can ask your SIP provider for the STUN server.’s IP address and portnumber If you don’t need a STUN server, leave the SIP Provider field empty.For direct SIP telephony using OpenCom 510, only SIP IDs consisting ofnumbers for identifying subscribers registered with the SIP provider specifiedcan be addressedFor each SIP account you can create just one bundle. You can specify thisbundle in routes as a connection option. You can use a network provider ruleto specify the routing of numbers within a specific range to use SIP telephonyas a preference (see also PBX Networking, under Configuration starting onpage 157).125

Voice over IP (VoIP)VoIP System TelephonesYou can configure SIP connections in the Configurator on the pagesPBX Configuration: SIP: Accounts and PBX Configuration: SIP: Provider. Enterthe technical attributes of a specific SIP provider, such as the IP addresses for theregistrar and the STUN server under Provider. Under Accounts enter the informationfor an existing SIP account, such as the user name, password, assigned callnumber and the maximum number of simultaneous calls possible.11.4 VoIP System TelephonesThe following telephones and software packages are available for VoIP systemtelephony:■■■■OpenPhone73IP: This is a VoIP-enabled edition of the OpenPhone 73 systemtelephone. This system telephone can be extended with up to three keypadextensions (KeyExtension 73P).OpenPhone75IP: This is a VoIP-enabled edition of the OpenPhone 75 systemtelephone. This system telephone can be extended with up to three keypadextensions (KeyExtension 73P or KeyExtension 75D).OpenPhone IPC: This VoIP software offers the functionality of a system telephoneusing Windows 2000/XP executable software (see OpenPhone IPCstarting on page 131). This software also provides local answering machinefunctionality and can be integrated into CTI applications.The older VoIP system telephones OpenPhone 63 IP and OpenPhone 65 IP canstill be used.11.4.1 Device PropertiesThe VoIP-enabled versions of the system telephones OpenPhone 73 IP andOpenPhone 75 IP offer the same features as the corresponding system telephones.Using VoIP system telephones is therefore not much different from usingstandard system telephones. The following differences exist:■Two RJ45 connector ports are available for ethernet connection. The ports areconnected to one another via the telephone’s internal switch. The switch supports10 Mbit/s or 100 Mbit/s full-duplex with priority given to VoIP data transmission.126

Voice over IP (VoIP)VoIP System TelephonesLAN Port: Allows the telephone to connected to the LAN. Use a non cross-overRJ45 patch cable to connect to a Hub or Switch.PC Port: Allows the telephone to be connected to a workplace computer. Use anon cross-over RJ45 patch cable to connect to the PC’s network port.■■■■■■The VoIP system telephone’s power supply is provided by an extra plug-inpower supply. It is also possible to provide a power feed via PoE (“Power overEthernet”). PoE requires special devices for power feeds, as well as a completelywired RJ45 connection line.You can also connect a standard headset via RJ45 sockets (DHSG standard) toVoIP system telephones.VoIP system telephone’s audio signals are generated by the telephone itself.DTMF dial tones and Music on Hold are produced by the Media Gatewayfunction.A VoIP system telephone can also be operated without a permanent connectionto the communications system, for example via an on-demand RASconnection.Signalling data for call control, call data during three-way conferences, connectionsto conventional terminals and external connections is exchangedbetween the VoIP system telephone and the communication system. During acall between two VoIP system telephones, call data is exchanged directlybetween the two VoIP system telephones.During the device’s start procedure, the IP address is configured and the devicesoftware is requested via the DHCP and TFTP network protocols.11.4.2 VoIP System Telephone ConfigurationThe VoIP system telephones OpenPhone 73IP and OpenPhone75IP obtain therequired IP address configuration and operating software via the DHCP, BOOTPand TFTP IP protocols. After the power supply is assured, the device’s internal bootloader is started which controls the further start procedure.Standard operating procedure is to contact the OpenCom 510’s DHCP server sothat the start procedure can be concluded without problems. To register a newVoIP system telephone, proceed as follows:127

Voice over IP (VoIP)VoIP System Telephones1. Temporarily remove the VoIP system telephone’s ethernet connection. Switchon the VoIP system telephone’s power supply. Note the MAC address shown inthe display, for instance “MAC: 00:30:42:00:00:00”. Switch off the power supply.2. In the Configurator, open the PBX Configuration: Devices: VoIP Phonespage. Click on the New button.3. Select the VoIP system telephone’s Type and enter the previously noted MACaddress. Assign a Name and Phone No. Confirm with Apply.4. Connect the ethernet connection with the VoIP system telephone’s RJ45 connector.Switch on the power supply. Verify the correct start procedure on thedisplay.11.4.3 LAN DHCP ServerIf the LAN already uses a DHCP server to configure workplace computers, there arevarious options for correctly responding to VoIP system telephones’ DHCP, BOOTPand TFTP requests. A comparatively simple approach is described here.1. Configure the LAN’s DHCP server to ignore DHCP requests from the VoIPsystem telephones. With a Linux DHCP server program, you must, for example,include the following lines in the system file “/etc/dhcpd.conf”:group {deny booting;host 192.168.11.12 {hardware ethernet 00:30:42:00:11:22;}}Every DHCP service program has similar options. You may need to reserve afree IP address for each VoIP system telephone. You will find more details inyour DHCP service program’s online help or handbook. The MAC address of allVoIP system telephones always begins with 00:30:42.2. Configure a fixed IP address for the OpenCom 510. To do this, call up the Configuratorand open the NET Configuration: LAN page. Click on the Changebutton.128

Voice over IP (VoIP)VoIP System Telephones3. Select from Get addresses from the DHCP server the option no. Enter thecurrent IP address configuration in IP address and Network mask. Confirmwith Apply.4. Configure the OpenCom 510’s DHCP server to assign IP addresses. To do this,call up the Configurator and open the NET Configuration: LAN: DHCPServer page. Click on the Change button.5. From Status, select the address assignment option. Confirm with Apply. TheDHCP Server page is re-displayed.6. Add the configured VoIP system telephones to the list of IP addresses. Click onthe New button.7. Enter the VoIP system telephone’s IP address and MAC address. Enter the IPaddress reserved by the DHCP service program. Confirm with Apply.Restart the OpenCom 510 and all connected VoIP system telephones.11.4.4 Start ProcedureIt may sometimes be useful to understand a VoIP system telephone’s start procedure.Examples:■■A complex DHCP address assignment prevents the operation of theOpenCom 510’s DHCP server within the LAN.A VoIP system should be operated with a non-broadcast-capable IP connection.This may be an RAS connection, a VPN connection or another type ofrouted connection.An external DHCP server can also control a VoIP system telephone’s start procedure.In this case, system software matching the type of VoIP system telephonemust be transferred via TFTP.After the VoIP system telephone has been connected to the mains power supply,the start procedure is as follows:1. The boot loader starts and shows the VoIP system telephone’s MAC address inthe display. A DHCP request is sent simultaneously via broadcast on the255.255.255.255 broadcast address.129

Voice over IP (VoIP)VoIP System Telephones2. An IP address, network mask and the default gateway for the start procedureare sent from the DHCP server. Via the “Next server” option, the DHCP serveralso provides the TFTP server’s IP address and the operations software’s filename. The DHCP server uses the MAC address to select the operations softwarefile which matches the type of device.3. The boot loader loads the operations software file from the specified TFTPserver. The TFTP server’s IP address and the file’s name are shown in the display.The loaded operations software is started.4. The operations software sends a DHCP request on the broadcast address255.255.255.255. The VoIP system telephone now receives an IP address,network mask and default gateway for operations from the DHCP server. Using“Option 43”, which is reserved for this purpose, the DHCP server also providesthe IP address of the communication system and port number 8100 for registration.5. The VoIP system telephone creates a TCP connection to the supplied IPaddress/port-numbercombination and sends a registration query. TheOpenCom 510 checks the MAC address sent with the registration and confirmsthe registration request if the VoIP system telephone is listed in the menuPBX Configuration: Devices: VoIP Phones. The keep-alive time, port number(8101) for telephony signalling and the value to use for the TOS byte are alsocommunicated in the registration answer.6. The VoIP system telephone creates a second TCP connection using the signallingport number 8101 and sends a registration analogue to the U pn systemtelephones.7. Extra connections are created using the IP protocol RTP (“Realtime TransportProtocol”) for call data when a call is created. For calls between two VoIP systemtelephones, port numbers above 8200 are used. For transmission to a MediaGateway card, a port in the range 1024 – 1087 is used.If you wish to operate a VoIP system telephone via a routed IP connection (forexample VPN or RAS) it may be necessary to configure an external DHCP serveraccordingly. Please note the selection of the codec and keep-alive time for RASconnections. This can be done by selecting the default profile RAS in thePBX Configuration: Devices: VoIP Phones for the VoIP system telephone. Theoperations software provided via TFTP must match the type of device and communicationsystem. You may also need to configure BOOTP, DHCP and TFTPservers for the VoIP system telephone.130

Voice over IP (VoIP)OpenPhone IPC11.5 OpenPhone IPCBesides the hardware VoIP system telephones, PC software for VoIP telephony canalso be deployed. This software can be used with the operating systemsWindows 98 SE/ME and Windows 2000/XP.Software VoIP system telephone OpenPhone 75 IPC with one keypad moduleAs well as VoIP system telephony from workplace computers, the OpenPhone IPCincludes the following features:■■■■■■Usage via Mouse/PC keyboard“Drag & Drop” call number selectionIntegrated answering machine / recording functionTerminal control for the sight-impairedSelectable user interface (“Skins”)Display language modificationThe workplace computer requires a full-duplex-enabled sound card as well as asuitable headset for audio recording and playback.131

Voice over IP (VoIP)OpenPhone IPCYou will not need a licence to install OpenPhone IPC but you will require a licenceto operate it with the OpenCom 510. Unit licences, enabling the simultaneousoperation of a certain number of OpenPhone IPCs, are available.The licences are activated in the OpenCom 510’s Configurator in the MenuSYS Configuration: Licences. The system software includes a licence for a demoversion for temporary use (60 days). Please contact your local agent or DeTeWerepresentative if you wish to purchase a permanent licence. Licences can be combined.Each licence can be activated only once.11.5.1 InstallationInstallation is done using a setup program. The OpenPhone IPC can also beinstalled without a user interface. The program can then be used via a CTI application(Net-TAPI or OpenCTI).Start the installation program from the OpenPhone IPC product CD and follow theinstallation assistant’s instructions.11.5.2 ConfigurationAnalogue to the VoIP system telephones, the OpenPhone IPC creates multiple IPconnections to the OpenCom 510. When you start the program for the first time,the Options dialogue is automatically opened. Here you must configure the followingvalues:1. Enter in the VoIP IP Address field the OpenCom 510’s IP address.2. Enter six hexadecimal-digits into the Device ID field. This device ID is not aMAC address, so overlapping with existent MAC addresses is possible. Thedevice ID is configured in the Configurator, on the PBX Configuration:Devices: VoIP Phones page.3. Confirm with OK.NotesVoIP system telephony requires an active IP connection to a workplace computer.If a Firewall is installed for your workplace computer, you may need to explicitlyallow this connection.132

Voice over IP (VoIP)OpenPhone IPCIf you log on to the workplace computer using a different user name, you mustreconfigure these values.You can use any arbitrary sequence of digits not already in use in the LAN for thedevice ID. Select a random device ID to secure telephone usage. The device ID canonly be read on the Web console.The displayed menu texts and parts of the operations software are elements of theOpenPhone IPC installation, but they can be loaded from the OpenCom 510 viaTFTP. where necessary133

DECTnetIPProperties12. DECTnetIPIn order to achieve optimal network coverage, a DECT network with several DECTbase stations can be operated. A DECT network is comprised of DECT terminalsconnected with the next respective base station (network cell). For users of a DECTterminal, the handover from DECT base station to base station is completely transparent.Even during a conversation, users are switched from one network cell tothe next without any interruption. Administration of DECT terminals is done centrallyvia the OpenCom 510 Configurator in the PBX Configuration: Devices:DECT Phones menu.12.1 Properties12.1.1 DECT base stationsDECT base stations can be connected to the OpenCom 510 via U pn accesses or vianetwork (TCP/IP). These DECT base stations are available for the type of accessselected:■■RFP 22: Access via U pn with lines up to 1000 metres in length; integratedantennas; 4 voice channels (8 when using 2 U pn accesses)RFP 24: like the RFP 22; mounted outside enclosed areas (IP55); externalantennasNote: The newer DECT base stations RFP 22 and RFP 24 canbe simultaneously operated with the older DECT base stations,RFP 21 and RFP 23. Fax transmissions (group 3 withECM) and SARI (roaming with Secondary Access Rights IdentificationBroadcasts) can be done using the newer DECTbase stations. Data transmission via DECT is not availablewith the newer DECT base stations.Note: The DECT base stations RFP32, RFP34 and RFP42support the DECT encryption function. This feature is however,only available if all the DECT base stations support it.134

DECTnetIPProperties■■■RFP 31/32: Access via shielded CAT5 Ethernet cable (STP cable, ShieldedTwisted Pair cable) with up to 100 metres of cable from the last Ethernetswitch, integrated antennas; 8 voice channelsRFP 33/34: like the RFP 31; mounted outside enclosed areas (IP55); externalantennasRFP 41/42: Access via shielded CAT5 Ethernet cable (STP cable, ShieldedTwisted Pair cable); offers simultaneous function of a WLAN Access Point conformingwith the IEEE 802.11b/g protocol; external antennas; 8 voice channelsNote: When started, the operating software for the DECTnetIPbase stations is transmitted via TFTP protocol from theOpenCom 510. The configuration for the start sequence istransmitted by the DHCP server of the OpenCom 510 to aDECTnetIP base station for the start sequence.If VoIP telephony is already being used, Ethernet cable access makes good sense.Transmission of telephony signalling and voice data via TCP/IP also offers usage ofexisting network infrastructure and an increase in range using suitable methods.VPN connections, for example, can be used for data links to provide service toremote or hard-to-reach locations.12.1.2 FeaturesAll DECTnetIP base stations can be connected to a CAT5 Ethernet cable with a 10/100 Base T. Power is supplied either via Power-over-LAN (IEEE 802.3af) or via anadditional power supply unit.Please note: The WLAN function of the RFP 41/42 is activated when connectedto the 100 Base T.DECT terminals offer all system telephony features. DECT telephones supportingthe GAP standard can also be operated. Transparent GAP device handovers aresupported. DECT encryption of calls can be deactivated for the RFP 32, RFP 34 andRFP 42 if desired.VoIP audio communication between the DECTnetIP base station and theOpenCom 510 is made via the RTP/RTCP protocol. RTP voice data are directly convertedinto DECT voice data by the base station. The base stations support theVoIP codecs G.711, (uncompressed) as well as G.729 and G.723 (compressed).135

DECTnetIPConfiguration12.2 ConfigurationOne of the DECTnetIP base stations that is installed assumes coordination andconfiguration of the DECT-over-IP functions (DECTnetIP-Manager). Select a basestation that has a dependable data link to the OpenCom 510. Go to the PBX Configuration:Devices: DECTnetIP page in the Configurator. Enter the MAC address ofthe base station that you have selected to be the DECTnetIP Manager. The MACaddress of the base station is located on its type label. You must enter a fixed IPaddress for this base station. All other base stations can be operated using either afixed IP address or an IP address assigned dynamically via DHCP. Please refer to theinformation given in the chapter entitled LAN DHCP Server starting on page 128.Note: A base station cannot be operated as a DECTnetIPManager and a WLAN-Access Point simultaneously.Youshould therefore use a DECTnetIP base station which doesnot have WLAN function as your DECTnetIP Manager.Create a separate entry for each DECTnetIP base station and for the DECTnetIPManager on the PBX Configuration: Devices: DECTnetIP page. You use theseentries to determine the VoIP data compression (Profile).Configurator: PBX Configuration: Devices: DECTnetIPUser administration and set-up of DECT terminals is done in the Configurator ofthe OpenCom 510 as well.The DECTnetIP Manager offers a separate web user interface to manage the settingsof devices with WLAN functions. Therefore at least one WLAN-RFP has to beconfigured. If everything is configured correctly, you will see the WLAN Configlink. Login as the user “Administrator” with the currently set administrator’spassword of the OpenCom 510.136

DECTnetIPConfiguration12.2.1 Dual operationSimultaneous operation of base stations via U pn access and base stations via Ethernetaccess is possible with the OpenCom 510. Transparent handovers, forexample, are only possible when between DECT base stations using the sameaccess technology. When switching over to a DECT base station using differentaccess technology, a DECT terminal automatically re-establishes a connection(roaming).Be sure to keep the PARK ID of your OpenCom 510 in mind. The PARK ID is displayedunder System Info: Versions in the Configurator. If the PARK ID starts with31, there may be an attempt at a handover between DECT base stations using differentaccess technology. In this case, make sure that the signal areas of the DECTbase stations using different access technology do not overlap. If the PARK IDstarts with a different value (e. g. 30), prevention of unintentional handovers iseffective.12.2.2 SynchronisationTransmissions of all DECT base stations at a single location must be synchronisedin order that DECT terminals are able to receive multiple DECT base stations simultaneously.Synchronisation can be conducted via U pn access. It cannot be conductedvia an Ethernet/IP connection. DECTnetIP base stations are thus synchronisedvia wireless connection.When planning a larger sized DECT network, it is advisable to take the followingpoints into consideration:■■■All DECTnetIP base stations at a single location must be able to receive at leastone, or even better, two neighbouring base stations. Synchronisation requiresless signal strength than a voice connection does.Synchronisation range is increased using multiple base stations. To decreasethe probability of a connection breakdown, base stations should not bearranged in chain formation. The signal should be distributed with a networkthat is as extensive as possible and where each base station is supported bymultiple synchronisation partners.To re-synchronise, first wait for all current connections to be terminated.137

DECTnetIPConfigurationYou can operate a DECT network consisting of several remote locations(“clusters”). A cluster is a number of DECT base stations that operate synchronouslywith each other. No handover is possible between DECT base stations fromdifferent clusters. You should configure a second cluster for DECT base stations ofa second location.12.2.3 Setting up the WLAN functionThe RFP 41 and RFP 42 DECTnetIP base stations provide the additional function ofa Wireless LAN Access Point (WLAN-AP). WLAN refers to data transfer by means ofradio waves in accordance with the IEEE 802.11b/g standard. This standardenables a wireless connection to be made to an Ethernet network (LAN) usingsuitably equipped user terminals. Data transfer via radio waves is very fast.Depending on the conditions of the operating environment, it can reach speeds ofup to 54Mbit/s (gross).WLAN settings are configured centrally for all Access Points using a separate Webconfigurator, which can be found at the IP address of the DECTnetIP Manager(OMM, OpenMobility Manager). You can reach this address by entering the IPaddress of the DECTnetIP Manager directly into the address bar of your WebBrowser. Alternatively, you can also go to the Configurator, to the page PBX Configuration:Devices: DECTnetIP and click on the WLAN Config. button. Log inunder the User Name “Administrator” and enter the same password as for theOpenCom 510.DECTnetIP/OpenMobility Managers Login PageThe WLAN function and the function of the DECTnetIP/OpenMobility Managercannot be used simultaneously on the same DECTnetIP base station, so you willalways need at least two DECTnetIP base stations. The WLAN settings are thenmade as follows:138

DECTnetIPConfiguration1. Set up the existing DECTnetIP base stations in theOpenCom 510’s Configurator.Go to the DECTnetIP Manager’s Web Configurator.2. On the WLAN Profiles page, configure at least one set of settings (see belowunder: Setting up a WLAN profile). Note down the password you have used(“Pre-Shared Key”), so that you will be able to use it again later when setting upwireless user terminals or notebooks.3. Assign the desired WLAN profile on the Radio Fixed Parts page. Click onspanner symbol ( ) on the left next to the relevant DECTnetIP base station.Under WLAN Settings select the number of the configured WLAN Profile.Confirm your settings with OK. You can use one profile for multiple DECTnetIPbase stations.You can now use the WLAN function of your WLAN-enabled DECTnetIP base stationsand set up the user terminals as required.Setting up a WLAN profileThe WLAN function of the RFP 41and RFP 42 DECT base stations also includes suchrarely-required features as networks for large company premises or airports. In thisguide we will, for the sake of brevity and clarity, describe only those featuresrequired for secure standard operation.DECTnetIP/OpenMobility Manager: WLAN ProfilesUse the following settings for standard operations.139

DECTnetIPConfigurationGeneral Settings■■■Select the desired WLAN Profile and activate the Profile Active option.Enter a SSID (Service Set Identifier, wireless network identification) to identify anetwork. This network identification is transmitted at regular intervals, makingit easier to find the networks you’re looking for, using the “View availablewireless networks” function in Windows XP, for example.For standard operation you should leave the following settings at their defaultvalues: VLAN Tag at 0 (Off), Beacon Period at 100 ms, DTIM Period at 5, RTSThreshold at 2347 (Off ), Fragmentation Threshold at 2346 (Off ), MaximumBitrate at 54 MBit/s, 802.11b/g Mode at “Mixed” and Interference Avoidanceon “Off”.Tip:If you are using only modern WLAN cards with 802.11g, youcan further speed up data transfer by configuring the setting802.11b/g Mode to “802.11g only”.■You can prevent the transmission of wireless network identification (SSID) withthe Hidden SSID Mode setting. This will however make network identificationdifficult and does not generally increase data security, so it is preferable toleave this on the default setting of “Off”.Security SettingsOn no account should you use Open System or Wired Equivalent Privacy (WEP)settings, whether out of convenience or in order to avoid configuration problems,unless of course you want to start up an Internet Cafe!■■■Activate the Wifi Protected Access (WPA) option.Under Type select the “WPA v.1”setting. If you are running the MicrosoftWindows XP operating system from ServicePack2 or higher on your computer,you can use the “WPA v.2” setting.For standard operation select the Pre-Shared Key option. Enter a password inthe Value input field and leave it set to Text. Use a password with the followingcharacteristics:– No words or names that can be found in a dictionary– At least 8 characters long140

DECTnetIPConfiguration– It should also include numbers, a mixture of upper and lower case andspecial charactersYou could also use the Generate button to generate a password. Some WLANconfiguration software does not convert text into hexadecimal values as astandard procedure. If this is the case, go to the Hex Value setting and selectthe Generate button.■Leave the Cipher Length setting at 256 Bit and the Distribution Intervalsetting at 120 seconds. You will not usually need the settings for WME or forconfiguring Multiple SSIDs for standard operation.Tip:If you are running an Internet-Cafe without using powerfulencryption, you should, for the sake of your customers’ security,prevent them from being able to access each others’computers. Activate the BSS Isolation option. You can alsostop unpleasant guests from using the system with a MACAddress Filter - but this will not hold up users who knowabout this function for long.12.2.4 Configuring for a remote locationIf you are using a DECTnetIP base station in the same LAN as the OpenCom 510,the IP address configuration and software loading procedure which are run whena DECTnetIP base station is started are handled by the OpenCom 510 using theDHCP and TFTP protocols.For the DHCP function to be available, the DECTnetIP base station must be able toreach the OpenCom 510 via a “Broadcast”. In the case of a remote location thiskind of access - via a VPN connection for example - will not be possible. As in thecase of an IP system telephone, you will have to acquire the necessary systemsoftware for the DECTnetIP base station with the help of a TFTP server.Local IP address configurationThe IP address configuration can be set up as a “local configuration” with the helpof an additional program.1. Open the product CD and call up the “OpenMobility Configurator” Javaprogram. Open Windows Explorer, go to the “DeTeWe” directory and doubleclickon the OM_Configurator.jar” file.141

DECTnetIPConfigurationNote: You need a Java runtime library to be able to run Javaprograms. If you don’t have one installed, you can install oneby starting the “j2re-windows-i586-p.exe” installation program.OpenMobility Configurator2. Enter the MAC Address of the DECTnetIP base station.

PBX CascadingVariants of PBX Cascading13. PBX CascadingAs requirements grow, the OpenCom 510 can be operated together with otherPBX installations. If you merely need a larger number of connections, it is easy tolink a second PBX (PBX Cascading). If you want to operate the OpenCom 510 atseveral locations with different PBXs, this is possible by PBX Networking (seepage 151).13.1 Variants of PBX CascadingYou can combine two PBXs in order to increase the number of terminals that canbe connected. A master PBX and a slave PBX are connected to one another bymeans of a cable. The two PBXs essentially function like a single PBX with a highernumber of ports. The master PBX controls the slave PBX. The following PBXs fromthe product family can be used for cascading:Master systemSlave systemOpenCom 130 OpenCom 130OpenCom 150 RackOpenCom 150 RackOpenCom 510 OpenCom 510For the PBX Cascading you will need a license. The license agreement provides youwith the necessary steps to activate this function.13.2 Functionality of PBX CascadingCascaded PBXs must be connected by means of a twisted-pair lead with RJ45plugs. All eight pins of the lead must be wired 1 to 1. Both voice and administrationdata are transferred via this lead. Connect the lead to the PCM ports of thetwo MC+1-3 central control modules of the PBXs. The shielded CAT-5 lead mustnot be longer than 50 centimetres.Note: Owing to the very short permissible lead length, thetwo PBXs have to be stacked. It is not possible to place themside by side.145

If you want to cascade two OpenCom 510 PBXs, you will need to set the framenumber using the DIP switches on the central control module.To access the DIP switches, remove both central control modules (master andslave systems); proceed as described in Installing the Central Control Modulestarting on page 29.2. Set the DIP switches of both modules as follows:DIP Switch SettingsFrame as MasterFrame as SlaveS1: open (switch set to “1”) S1: closed (switch set to “ON”)S2: open (switch set to “2”) S2: open (switch set to “2”)For the location of the DIP switches (S1and S2), refer to the illustration MC+1-3:Top view.3. Re-install the central control modules in the frames.146

Connect asystem telephone to the slave system for a later performance check. Use theU pn 1 terminal of an existing MS+UPN1-8 oder MS+UPN2-8 interface card.2. Back up the master system data. For further information, refer to the onlinehelp topic SYS Configuration: Data Backup. The backup procedure alsostores the current configuration data to the CompactFlash memory card.3. Switch off the master system if it is operating. Disconnect the module from thepower supply by pulling out the mains plug.4. Connect the two modules by means of a suitable cable as described above.5. Power on the two PBXs. The order in which you do this does not matter.6. In the PBX Configuration: Ports: Slots dialogue of the master system’s Configurator,click on Slave. Select the slave Type in the Slave: Change dialogue.147

PBX CascadingPutting a Cascaded PBX into OperationPlease note:If you change the type of slave system later on, the port settingsthat have been made will be deleted.The master system then initialises the slave system. This may involve transfer offirmware (operating software) from the master system to the slave system. Thiscan take a few minutes.7. Configure the system telephone connected to the slave system for testing purposesin the Configurator. In the PBX Configuration: Ports: Upn dialogue,click on one of the additionally displayed entries of the type Upn 1/m/n(1: slave system, m: slot number, n: U pn port number).Note: Changes to the configuration while initialising theslave system may trigger error reports referring to the ongoinginitialisation.You can see that the initialisation has been completed from the display on thesystem telephone connected to the slave system.148

PBX CascadingPutting a Cascaded PBX into Operation13.3.1 NotesObserve the following when operating a cascaded PBX system:■■■■■■■■All U pn , S 0 and a/b ports of the slave system interface cards can be used withappropriate telephones. All features of system telephones on U pn ports areavailable without restriction.The S 0 ports of the slave system can also be used for trunk lines or for PBX networking(see PBX Networking starting on page 151).It is not possible to operate a DECT base station on one of the U pn ports of theslave system.The ISDN-L1 reference clock signal is always transferred from the master to theslave system and must be acquired from an S 0 port –or preferably an S 2M -port– on the master system. The master system therefore needs to be connectedto at least one ISDN trunk line.It is possible to operate an S 2M interface card of the type MS+S2M1-1 in theslave system. As the ISDN-L1reference clock signal supplied by an S O interfacecard is not precise enough, you will also need to operate an S 2M interface cardin the master system.The slave system cannot be addressed directly through a LAN. For configuration,always use the Web console of the master system.A memory card installed in the slave system cannot be used.To operate the slave system again normally, you must reset it to its factory settings(refer to Resetting the System Data starting on page 101 and DIP SwitchSettings on page 146).149

PBX CascadingLicensing Information13.4 Licensing InformationA licence is required for certain additional OpenCom 510 program packages, forexample for the internal voice-mail system called OpenVoice.The following information is for customers who have already obtained licences foran OpenCom 510 and would like to cascade or network their existing system withanother OpenCom 510.PBX NetworkingIf you network two OpenCom 510 systems with each other, you needn't generateany new activation keys but can continue to use the corresponding functions onthe existing OpenCom 510. The “disadvantage” of this alternative is that you haveto administer a separate configuration on each OpenCom 510.PBX CascadingIn the case of PBX cascading, the master system administers the overall configuration.If you have already installed activation keys on an existing OpenCom, they have tobe ported to the master system.In this case, new activation keys for the use of additional program packages mustbe generated on the DeTeWe licence server (http://lizenz.aastra-detewe.de). Thelicensing confirmation for the cascading contains all the information you need tocarry out this procedure.Note: You will need the serial numbers of both infocom systemsfor porting the activation keys. The serial numbers canbe found in the Web console's Configurator, in the SystemInfo: Versions menu.150

PBX Networking14. PBX NetworkingOpenCom 510 provides all the features necessary for PBX networking. You needPBX networking in the following cases:■■■To operate the OpenCom 510 as a subsidiary system on another PBX. This willalso allow you to use the OpenCom 510 as a DECT server, for example.To network the OpenCom 510 with an OpenCom 1000. In this way you can usethe OpenCom 510 as a PBX for a branch office, for instance.To network several OpenCom 510s into a PBX system.■ To use flexible configuration possibilities of trunk lines for a OpenCom 510.All settings that affect the configuration of PBX networking can be found in theConfigurator menu PBX Configuration: Trunks and in the PBX Configuration:System: Settings dialogue under System linking. Refer also refer to the correspondinghelp topics in the OpenCom 510 online help.You can use ISDN point-to-point connections (Q.SIG or DSS1 protocol) or IP connections(Q.SIG-IP protocol) for TK system networking.Note: If you do not need the features of PBX networking,the simplified configuration is sufficient in most cases. Forthis purpose, assign the preconfigured trunk groups (bundles)Multi-terminal access or System access to the ports.The preconfigured route called External trunk now makes itpossible to seize an external line immediately or by first diallingthe prefix “0”. You can rename the preconfigured bundleand the preconfigured route if required, but you cannotdelete them.151

PBX NetworkingConnections14.1 ConnectionsNetworking two or more TK systems means interconnecting them. TheOpenCom 510 allows you to use the following connections:■■■ISDN trunk linesISDN point-to-point connections (Q.SIG) on external S 0 ports or on the S 2M portIP network connections (Q.SIG-IP)PBX PBX PBX PBXPBXTrunk linePoint-to-pointconnectionExample of a PBX networkVarious line types and transmission protocols can be used for point-to-point connections.The required network topology (distance, connection capacity) determineswhich type of point-to-point connection is most suitable.14.1.1 Protocol: Q.SIG or DSS1The Q.SIG protocol, designed for ISDN point-to-point connections, is the preferablechoice as the transmission protocol; alternatively, the DSS1 protocol,designed for ISDN dial-up connections in the Euro-ISDN, can be used. Certain PBXnetworking features can only be used with the Q.SIG/Q.SIG-IP protocol, however.In particular, the identifier indicating whether a call is internal or external cannotbe transmitted using DSS1.Both protocols implement communication on several protocol layers:■■■L1: Layer 1 defines the physical line properties and the electrical coding ofsignals.L2: Layer 2 enables communication via individual error-protected channelsthat are independent of each other.L3: Layer 3 defines the administration of the individual channels and implementsthe features designed for ISDN.152

PBX NetworkingConnections14.1.2 Master/SlaveNote: All layers of the Q.SIG-IP protocol are symmetrical. Thefollowing are unnecessary: a Master/Slave setting, clock andsynchronisation settings (please refer to Connection viaQ.SIG.IP starting on page 156).For an ISDN connection, it is possible to determine which PBX is the protocolmaster and which the protocol slave. This relationship can be determined for allthree protocol layers independently of one another.For each protocol layer, the PBX at the other end always has to be suitably configured.If one PBX is the protocol master for a layer, the other PBX must be theprotocol slave for this same layer. Normally all three protocol layers are configuredidentically. In the case of a trunk line, the network operator is the protocol masterfor all three layers.14.1.3 L1 ClockNote: In the case of an S 2M line, it is also possible to determinefor each useful channel which end can administer achannel (master = internally seized or slave = externallyseized). On S 0 lines this setting is determined by “L3 master”for both B-channels.To enable PBXs in the ISDN network to communicate with each other, they mustbe “clock-aligned”. The L1 protocol master sets the clock for layer 1, and the L1protocol slave adopts (synchronises to) this clock.When planning a PBX networking scheme, you must make sure that the L1 clockpropagates from a master via a number of PBXs.NetworkoperatorMSPBX1MSPBX 3MSSPBX 2MTrunk linePoint-to-pointconnectionExample: propagation of the L1 clock153

PBX NetworkingTypes of Point-to-Point ConnectionsIf more than one port with the setting L1 Type = “Slave” is configured on anOpenCom 510 and the setting L1 sync possible has been activated, then one ofthe ports is automatically defined as the L1 clock source. The OpenCom 510 willautomatically switch the clock source to another port configured as an L1 clocksource (if a line fails, for example).LED 3 (top right) of an interface card will light up if one of the interfaces on thecard has been selected as a clock source. If an S 2M interface of the type MT+S2M1-1 is installed, it will be selected as the preferred clock source.Please note: Reciprocal or circular application of the L1 clock is not allowed.Example: In the above case you could reverse the L1 slave/master setting for theconnection between PBX 1 and PBX 3. However, if you then activate the settingL1 sync possible for the port of PBX 1, this may cause parts of the PBX network tostop functioning temporarily.When applying the L1 clock of trunk lines, you can assume that the public networkis “clock-aligned”. So, in the above example, you can connect additional trunk linesto one of the PBXs.14.2 Types of Point-to-Point ConnectionsThere are different types of connection available for an point-to-point connectionbetween two PBXs, depending on the distance between them.14.2.1 Direct ConnectionThis type of ISDN point-to-point connection joins the two systems directly to eachother using a crossover twisted-pair cable. An S 0 connection can be used for distancesup to 1,000 metres, while an S 2M connection can span up to 250 meters.Normally one PBX is the protocol master for all three layers, and the other PBX isthe protocol slave for all three layers.PBX 1L1 masterL2 masterL3 masterDirect connectionPBX 2L1 slaveL2 slaveL3 slave154

Normally the L1 master is the transmissionsystem for the two connected PBXs. For the protocol layers L2 and L3, onePBX is normally the protocol master and the other PBX is the protocol slave.PBX 1L1 slaveL2 masterL3 masterTransmissionSystemL1 masterPBX 2L1 slaveL2 slaveL3 slaveConnection by an active transmission systemNote: The active transmission system itself gets its L1 clockeither from the network operator or from a clock generatorconnected by wire.14.2.3 Connection via the Public NetworkPoint-to-point connections via the public network of a network operator can beused for bridging distances beyond 50 km. Due to the long distance involved, fortechnical reasons it is not possible to synchronise the L2 protocol. Consequently,the public network is normally the protocol master for protocol layers L1 and L2.One PBX is therefore the L3 master and the other PBX the L3 slave.155

The OpenCom 510 uses the Q.SIG protocol, for use with ISDN point-to-pointconnections and transports the protocol and voice data via IP connections.The number of simultaneous conversations possible will depend on the capacityof the internet connection and the compression method used. A multiple S 2Mpoint-to-point connection is simulated for each Q.SIG-IP bundle. This means that 5virtual D channels and up to 120 voice channels are available. Both Media GatewayCard channels and the Media Gateway software function can be used for Q.SIG-IP.Q.SIG-IP connection data are subject to codec compression (please refer to Voiceover IP (VoIP) chapter regarding Fundamentals starting on page 116). Q.SIG-IP alsotransfers the voice data directly from terminal to terminal via the RTP protocol. Incertain cases, for example, when an incoming external call is placed via multiple TKsystems, one or more RTP proxies may be used to forward the connection.Currently, there are no standards for the necessary extensions to the Q.SIG protocol.This means that you can only use Q.SIG-IP between OpenCom 510 systems(exception: OpenCom 1000).Networking two OpenCom 510 systems using Q.SIG-IP requires 2 licenses – onelicense per system. The number of possible voice connections is not restricted bythe license.Go to the PBX Configuration: Trunks: Bundle page in the Configurator to set upa Q.SIG-IP connection. Create a new bundle and select the Access type “SystemAccess”. Select “Q.SIG-IP” under Protocol. Configure the IP address of the othersystem, the port numbers to be used, the number of possible voice connectionsand select a VoIP profile for the codec selection. Please refer to the relevant helptopics in the Online Help for the OpenCom 510 as well.156

PBX NetworkingConfigurationNote: Q.SIG-IP cannot be operated using a connection withNAT.14.3 ConfigurationThe possible configurations described below can be set up in the Web consoleusing the PBX Configuration: Trunks menu.14.3.1 Trunk groupsThis is a group of lines of the same type and direction. A line can only be assignedto one trunk group (bundle).NetworkoperatorABCPBX 1PBX 2EDPBX 3BundleTrunk linePoint-to-pointconnectionExample of a PBX network with trunk groupsIn the above example, the following trunk groups are configured for PBX 1:■Two S 0 lines in a multi-terminal configuration to the network operator whichare assigned to the “A” trunk group.■Two S 0 point-to-point connections to PBX 2 which are assigned to the “C” trunkgroup.■One S 0 point-to-point connection to PBX 3 which is assigned to the “E” trunkgroup.Note: A line or a trunk group cannot be seized directly. It isalways performed indirectly via a route.14.3.2 RoutesA route is a group of trunk groups enabling a connection in one direction. If thefirst trunk group of a route is fully utilized, the next trunk group is seized (“trunkgroup overflow”). One trunk group can also be used for different routes.157

PBX NetworkingConfigurationIn the above example, a route set up for PBX 1 allows a connection to PBX 2. Trunkgroups “C,” “E” and “A” are assigned to this route. If a user connected to PBX 1wants to reach a party in PBX 2, lines will be seized in the following order:■■■■PBX 1 first searches for a free channel in the “C” trunk group.If all the lines in trunk group “C” are busy, the system tries to set up a connectionvia trunk group “E”. PBX 3 switches the connection through, providedit is appropriately configured (refer to Numbering starting on page 158).If it was not possible to set up an indirect connection via PBX 3, the system triesagain via trunk group “A”. The “prefix” necessary for this can be configuredwith the route.The user does not get a busy signal until the attempt to set up an indirect connectionvia the network operator has also failed.Note: If an internal connection is switched via a network operator,the call is signalled using the external number of thecalling PBX.For each route you can define a randomly selectable code digit for seizing theroute. You can also configure whether a user is authorised to seize a particularroute, whether LCR is to be used for one of the trunk groups and the criteria(business or private call, booking numbers) for evaluating call data.14.3.3 NumberingA user can seize a particular route by pre-dialling a specific code digit. With this“open numbering”, a user must always dial this code digit and then the telephonenumber in order to reach a party in another PBX.If none of the telephone numbers in your PBX network occur twice, you can alsoconfigure “closed numbering”, allowing the same telephone number to be usedfor reaching each user within the PBX network.With closed numbering, the OpenCom 510 determines which route to seize fromthe telephone number dialled. The information needed for routing a call can beconfigured in a numbering table containing up to 100 entries. You use this table toassign telephone numbers and/or ranges of telephone numbers to a particularroute.158

PBX NetworkingConfigurationA default entry in the numbering table makes it possible to seize a “default route”for all remaining unassigned numbers. In particular, this simplifies configuration ofthe OpenCom 510 as a subsidiary system: the only entry you assign to the defaultentry is the route to the host systemPBX100-199bac4: bD: cdPBX200-299hge3: e5: hD: dfPBX300-399k5: kD: fPBX400-499D: aPBX500-599i3: iD: gD:DefaultRouteExample of closed numbering tablesThe automatic switching of call requests (i.e. routing) by means of trunk groupoverflow or default numbering can lead to “circular switching”.To avoid this, a “transit” counter is incremented whenever a connection isswitched through on Q.SIG lines. When the configured maximum value is reached,further switching stops.159

PBX NetworkingTechnical Details14.4 Technical DetailsA different PBX number must be set for each OpenCom 510 in a PBX network. Thissetting can be found in the Web console, in the menu PBX Configuration:System: Settings under the heading System linking. You can also set themaximum value for the transit counter there. This value depends on the topologyof the PBX network and should allow the system to have the maximum number offurther connections possible.You can display the connection status of the lines at any time in the Configuratormenu System info: PBX: Trunks. You should check this in particular after makingchanges to a configuration to see whether all the lines used for system networkingare operable.Some of the features possible in Q.SIG are not supported by OpenCom 510 with alltheir options, for example callback on busy within the Q.SIG network. The call categoriesdefined in Q.SIG (e.g. Emergency Call, Operator, Normal) and the Q.SIGname transmission feature (“user names”) are fully supported.The code digits to be used for seizing a route with open numbering are not transmittedto the destination PBX and thus cannot be evaluated by it. To reseize aroute (for example for a callback), you must set the appropriate digit prefixes in thetrunk group configuration for the routes to be reseized.Tip:If, for example, you are configuring a route which can beseized using routing code “5” and have selected one or morebundles for this route, change the Prefix for dest. call numberat incoming internal setting to “5” for this bundle in orderto enable the route to be reseized.160

Team FunctionsIntroduction15. Team Functions15.1 IntroductionWith the team functions you can manage your telephone communication tasks byassigning lines with separate call numbers to the keys of different terminals. Theterminal users, or team members, can thus pick up one another’s calls or telephoneeach other using the configured keys.Team functions can only be configured on the corded system telephones of theOpenPhone 6x and OpenPhone 7x product line because only these have therequired features.15.1.1 Explanation of KeysThe team functions are programmed on the call keys of the OpenPhone 6x/OpenPhone 7x telephones. Depending on the terminal, different numbers of callkeys are available:Number of available call-keysTelephoneOpenPhone 61OpenPhone 63OpenPhone 65OpenPhone 71OpenPhone 73Number of keysOne key with a display, five keyswithout a displayThree keys with a display, five keyswithout a display19 keys with a display: nine on thetelephone itself and 10 on an add-onkeypad moduleOne key with a display, five keys withouta displayThree keys with a display, five keyswithout a display161

A trunk keycan be programmed with a substitute function (with another team memberacting as the substitute). Calls for you are then signalled to the terminal ofanother team member. A trunk key also provides functions for managing calls.For example, you can configure call protection if you do not want to be disturbed,or call diversion to another telephone.Team key: As with a trunk key, a team key can be used to receive or make calls.However, this key cannot be used to change the settings for managing calls; itis not possible, for example, to configure call diversion to another telephone.Calls made via a team key are signalled to all terminals with a trunk key that hasbeen programmed with the same number. For example, the team key with thenumber 11 calls all trunk keys with the number 11.Busy key: The purpose of a busy key is to make the busy status of other teammembers visible. An incoming call for a busy team member is signalled on theother team member's busy key. That team member can take this call bypressing the busy key, which seizes his own terminal's trunk key. Calls taken viathe busy key are not entered in the call list of the team member who was originallycalled. In addition, it is possible to call the respective team member via hisbusy key when his terminal is idle. You set up a call to this team member bypressing your own trunk key.162

Team FunctionsIntroduction■Direct call key: Only outgoing calls can be made with a direct call key; they aresignalled to all terminals with the same number programmed to a trunk key.Calls via a direct call key are signalled to the destination terminal even if thatterminal has been programmed with a substitution function or call protection.If the destination terminal has been configured for call diversion, the direct callis not diverted.Which key is suitable for which purpose?■■■■Trunk keys can be assigned call numbers for managing central communicationtasks, for example, customer support. If the call numbers of the supportdepartment are assigned to trunk keys on all of its terminals, then all membersof the support department can receive and manage calls and use the substitutefunction.Team keys, for example, can be used to create a project group within adepartment. Calls from customers of this group can then be answered by anyteam member who is not busy. The team members can call each other by theteam keys.A busy key can be used to configure an enquiry station showing the status ofthe individual users. The enquiry station sees the status of the users and canput calls through by simply pressing the key.Direct call keys, for example, can be configured at a terminal in a conferenceroom to call the secretary.15.1.2 Team ConfigurationYou can create teams and program call keys in the Configurator of theOpenCom 510 (PBX Configuration: Groups and Ports: Upn menu).Call key 1 is preset as a trunk key on all system telephones. This setting can bechanged by the system administrator.163

Team FunctionsExamples of Use15.2 Examples of UseThe following examples illustrate the various uses of teams and team functions.For information on the display texts and how to use the individual functions, referto the chapter “Managing Calls in a Team” in the “OpenPhone 61, 63, 65” or “Open-Phone 71, 73, 75” user guide.15.2.1 Executive/Secretary TeamIn this example, the executive/secretary team comprises two members: the executiveand the secretary. The secretary has one OpenPhone 73 system telephone,and the executive has two, one of which is used as a parallel telephone in a sofasuite.1110SecretaryTrK 11: SecretaryTrK 10: ExecutiveDK 10: ExecutiveExecutiveTrK 10: ExecutiveTrK 11: SecretaryTrK 12: Private12Executive´s ParallelTrK 10: ExecutiveTrK 12: PrivateExample: executive/secretary teamLine SeizureThe secretary can be reached on the call number 11 (trunk key TrK 11: secretary’soffice).The executive can be reached on the call number 10 (trunk key TrK 10: executive’soffice). He can also answer calls from his parallel telephone. In addition, a privateline is configured for both of the executive’s telephones (trunk key TrK 12: private).164

Team FunctionsExamples of UseCall numbers 11 and 10 are both configured as a trunk key on the executive’s andthe secretary’s terminal respectively. Thus the executive and the secretary can useeither call number (for answering as well as making calls). Each can act as a substitutefor the other.The secretary’s terminal also has the executive’s call number configured as a directcall number (DK 10: executive’s office). The secretary can therefore reach the executiveand put through calls even if the executive has programmed a substitute.Line Busy IndicationIf a line is busy, e.g. TrK 11 secretary’s office, the other terminal will indicate this.The executive’s private calls via TrK 12 are not indicated on the secretary’s terminalsince no appropriate trunk key is configured on the latter’s telephone.Call SignallingIn this configuration example, calls to one’s own call number are signalled acousticallyon the following telephones:■■Call number 11 on the secretary’s telephoneCall numbers 10 and 12 on the executive’s telephone.Calls for the other team member’s call number are indicated by an optical signalon one’s own telephone (flashing trunk key LED).The parallel telephone will indicate calls only by an optical signal.Time-delayed acoustic signalling can be configured for TrK 10 on the secretary’stelephone. If the executive, for example, does not answer a call within 10 seconds,the secretary’s telephone will start to ring.If the executive activates a substitute function with the secretary as the substitute,calls for call number 10 will be indicated on the executive’s telephone by an opticalsignal only, but signalled acoustically on the secretary’s telephone. The secretarycan also activate a substitute function. Calls for call number 11 are then signalledacoustically on the executive’s telephone, and indicated by an optical signal on theparallel telephone and the secretary’s telephone.165

Team FunctionsExamples of Use15.2.2 Three-member TeamThe three-member team described here is an example of a team configurationwithin a project group, e.g. export sales.Each team member has one OpenPhone 73 system telephone with all call keysprogrammed as trunk and team keys.10MillerTrK 10: MillerTK 11: JohnsonTK 12: Smith11JohnsonTrk 11: JohnsonTK 10: MillerTK 12: Smith12SmithTrK 12: SmithTK 10: MillerTK 11: JohnsonExample: three-member teamLine SeizureEach team member’s call number, e.g. call number 10 for Miller, is programmed asa trunk key on his telephone.On the other telephones in the team, this call number is programmed as a teamkey (e.g. TK 10 on Johnson’s and Smith’s telephones). The team members can thussee which number a call is for and can answer it by pressing the appropriate teamkey.The team members can call each other via the team keys. For example, Miller cancall number 12 by pressing TK 12; the call is then signalled to Smith’s telephone onTrK 12.166

Team FunctionsExamples of UseLine Busy IndicationIf a line is busy, e.g. TrK 11 Johnson, the team keys 11 on Miller’s and Smith’s telephoneswill indicate this.Call SignallingIn this example, calls via the trunk keys are signalled acoustically. Calls via the teamkeys are indicated by a visual signal (the team key LED flashes).15.2.3 Unified TeamThe unified team described here is an example of a team configuration within adepartment in which calls are to be managed quickly (e.g. support department).Each team member has one OpenPhone 73 system telephone with all call keysprogrammed as trunk keys.MillerTrK 10: Support 1TrK 11: Support 2TrK 12: Support 31011JohnsonTrK 10: Support 1TrK 11: Support 2TrK 12: Support 312Example: unified teamSmithTrK 10: Support 1TrK 11: Support 2TrK 12: Support 3Line SeizureCall numbers 10, 11 and 12 are programmed as trunk keys on each team member’stelephone (TrK 10 to TrK 12.All team members can use these numbers for answering as well as making calls.167

Team FunctionsExamples of UseTip:In this team configuration it is useful to program one of thefunction keys on each telephone with the “Hold” function. Acall, e.g. for TrK 11, can then be put on hold by pressing thefunction key. If another team member then presses trunk keyTrK 11 on his telephone, he can accept the call.

For each member, these trunk keys areprogrammed either as support numbers or hotline numbers.The first support number and the first hotline number of each team member isprogrammed as a team key on the other member’s telephone, e.g. TrK 10 andTrK 15 on Miller’s telephone as TK 10 and TK 15 on Johnson’s telephone. Theassumption here is that most calls will go to the respective first call numbers, andteam members can thus help each other out by answering one another’s calls.On each telephone it is possible to toggle between the calls on individual lines,e.g. TrK 10 and TrK 11, by pressing the appropriate key (toggling).169

Team FunctionsExamples of UseEvery call on a trunk key can be transferred to any other party by means of the Rkey.

Calls via team keysare indicated by a visual signal (the team key LED flashes).170

Call QueueIntroduction16. Call Queue16.1 IntroductionA queue can be activated for the telephone numbers of any type of telephone, i.e.for system, analogue, ISDN and DECT telephones.If a call number with a queue is busy, calls to this number enter the queue. Thecaller first hears an announcement (if function “Announcer at busy” is configured)and then a dial tone.Calls which remain in the queue for too long are cleared from the queue. The callerthen gets a busy tone. If all the positions in the queue are taken then any furthercalls also hear the busy tone.The time until an external call is cleared from a queue is defined by the networkoperator. In Germany this is usually two minutes and in other European countriesusually three minutes.If more than one telephone number (e.g. trunk or team keys) has been configuredfor a telephone, separate queues are used for each number.On the OpenPhone 65/OpenPhone 75 system telephone, additional calls are signalledby a brief tone in the loudspeaker and in the display. If calls are in thequeue, a number at the beginning of the second line of the display on theOpenPhone 65/OpenPhone 75 indicates how full the queue is. If more than onetelephone number with a queue is configured on the telephone, the total numberof entries are displayed.Calls in a queue are handled by the OpenCom 510 in the following order of priority:instant connection, door calls, automatic recalls, VIP calls, then other internaland external calls. Sensor calls thus have priority over other calls, for example. Callsof the same priority level are switched in the order of their arrival.The system administrator sets the number of calls that can be placed in a queueindividually for each user group. The value can lie between “0” and “99”. The “0”value deactivates the ”Call queue” function for a user group. When the maximumnumber of calls in the queue is reached, further callers hear a busy tone.Only calls which have a “voice” service indicator are administered in a queue.171

Call QueueIntroductionNote: As calling fax machines often operate with the “voice”service indicator (e.g. on analogue ports), you should assignports for fax machines on the OpenCom 510 to a user groupwithout a queue.Queues can be combined with the “forwarding,” “pickup” and “hunt group” functions,for example, in order to configure an enquiry station for an operator.16.1.1 Activation of QueuesQueues can be activated on a per user group basis. On delivery the default set, forall preset groups, is off.When using queues, it often makes sense to activate call waiting protection. Forthis purpose, “Call waiting protection” authorisation must be allocated to the usergroup, and call waiting protection must be activated on the terminal.Furthermore it is sensible to combine queues with the “Announcer at busy”function. When a caller calls a subscriber who is busy then they will hear a “centralwelcoming text”, for example, “Here is company XYZ. You will be immediately connected”.The function “Announcer at busy” can be set in the PBX Configuration:Call Distribution: Incoming menu. Central welcoming texts can be recordedusing the program package OpenVoice.You should configure a new user group (e.g. “Operators”) and activate the authorisations“Call queue”, “Call waiting protection” and, if necessary, “Call forwarding”.If users belong to this group, a queue will be activated automatically for all telephonenumbers assigned to them.16.1.2 Call ForwardingForwarded calls of the forwarding type “Immediately” and “On busy” have priorityover queues. The queue of the forwarding telephone is not used for forwardingcalls in this manner.During the configuration of this type of call forwarding, the contents of the queueare not transferred to the target terminal. If there are still calls in the queue whenthe call forwarding function is activated, these calls can only be accepted on thesource terminal.172

Call QueueExamples of UseIf a call is to be forwarded “After delay”, it enters the queue. If the call has not beenanswered before the delay period expires, it will be forwarded to the target terminaland can then be answered there.16.1.3 PickupThe functions “Pickup” (from a pickup group) and “Pickup selective” can be usedtogether with queues. A user who accepts a call using “Pickup” or “Pickupselective” picks up the next call from the queue.16.1.4 Hunt GroupsHunt groups of the “parallel” type are usually used together with queues, with thequeues of each telephone in the group being synchronised to each other. When acall to the number of the hunt group arrives, the call enters all parallel queues. If acall from one of the queues is answered, it is removed from all other parallelqueues.16.2 Examples of Use16.2.1 Enquiry Station for an Operator with TwoSystem TelephonesThe operator switches all incoming calls and can either work on theOpenPhone 65/OpenPhone 75 or the mobile terminal, the OpenPhone 27.Configuration■■■Configure the system access or access for multiple terminals under PBX Configuration:Ports: S 0 .Configure the OpenPhone 65/OpenPhone 75 and e.g. a RFP 22/24 under PBXConfiguration: Ports: U pn .Configure a trunk key for the OpenPhone 65/OpenPhone 75 under PBX Configuration:System telephones.173

Call QueueExamples of Use■■■■■■Configure the OpenPhone 27 under PBX Configuration: Ports: DECT-PP andassign the OpenPhone 27 its own telephone number. Check in theOpenPhone 27.Under PBX Configuration: Call Distribution: Incoming or PBX Configuration:Call Distribution: Incoming PTP route all incoming calls to thenumber of the OpenPhone 65/OpenPhone 75 trunk key.In the Configurator, create a new group called “Operators” under UserManager: User groups. Activate “Call queue”, “Call waiting protection” and“Call forwarding” for this group and set the Dial out: External option appropriately.Create a user called “Operator 1” under User Manager: User. Assign this userto the “Operators” user group. Assign the telephone numbers of theOpenPhone 65/OpenPhone 75 trunk key and the number of the mobileOpenPhone 27 to this user.Activate Call wait. prot. (call waiting protection) on both terminals inthe Protection menu.Configure a function key on the OpenPhone 65/OpenPhone 75 which activates/deactivatesa “call forwarding immediately” to the telephone number ofthe mobile OpenPhone 27 (in the menu Call diversion: Divertphone: Immediately).UseIncoming calls are routed to the OpenPhone 65/OpenPhone 75 manned by theoperator, who then puts the calls through. A queue is used so that callers do notget a busy signal. The display on the OpenPhone 65/OpenPhone 75 indicates howmany calls there are in the queue.If the operator wants to leave the workstation and take along the enquiry station,call forwarding to the OpenPhone 27 is activated by pressing a function key. Callswhich are in the OpenPhone 65/OpenPhone 75 queue must still be answered onthis telephone. New calls are signalled on the mobile OpenPhone 27 or enter itsqueue, allowing the OpenPhone 27 to be used as a mobile enquiry station.On returning to the workstation, the operator deactivates call forwarding bypressing a function key. Calls which are already in the queue are switched on themobile OpenPhone 27. New calls are signalled on the OpenPhone 65/OpenPhone 75 or enter its queue.174

Call QueueExamples of Use16.2.2 Group of Three Enquiry StationsThe enquiry stations switch all incoming calls. Incoming calls are administered inqueues. Depending on the number of arriving calls, one to three enquiry stationsin this group are manned. The enquiry stations are each equipped with anOpenPhone 65/OpenPhone 75.Configuration■■■■■■■■■Configure the multi-terminal access or the system access under PBX Configuration:Ports: S 0 .Configure the three OpenPhone 65/OpenPhone 75 telephones under PBXConfiguration: Ports: U pn .Configure a trunk key with its own telephone number for each of theOpenPhone 65/OpenPhone 75 telephones under PBX Configuration:Devices: System telephones.Configure a hunt group of the “parallel” type under PBX Configuration:Groups: Hunt Group, and include the three telephone numbers of the trunkkeys in this hunt group.Under PBX Configuration: Call Distribution: Incoming or PBX Configuration:Call Distribution: Incoming PTP route all incoming calls to thenumber of the hunt group.In the Configurator, create a new group called “Operators” under UserManager: User groups. Activate “Call queue” and “Call waiting protection” forthis group.In the User Manager, configure a user for each of the three operators andassign these settings to the user group called “Operators”. Allocate each Userthe telephone number of the trunk key of their system telephone.Activate Call wait. prot. (call waiting protection) on all three terminalsin the Protection menu.Program a function key with the function “Sign on/sign off from hunt group”on the three system telephones (in the menu Calls: Hunt group).175

Call QueueExamples of UseUseIncoming calls are signalled in parallel to all signed-on enquiry stations. If theenquiry stations are busy, the incoming call joins the queue on each of the terminalsin the hunt group. If one of the enquiry stations accepts a call from thequeue, the call is removed from the queues of all the other enquiry stations. Thedisplay at each enquiry station (OpenPhone 65/OpenPhone 75) indicates how fullthe queue is.If attendants leave the station, they sign off from the hunt group by means of afunction key. In contrast to Example 1, further calls do not have to be processedafter the sign-off, as the calls are also registered in the queues of the other signedonenquiry stations.Note: When the last enquiry station remaining in the huntgroup signs off, further callers will hear the busy tone.176

Multi-Company Variant17. Multi-Company VariantCommunications systems are frequently shared by several companies. These companieswant to jointly use the existing infrastructure (e.g. the existing lines and featuresof the system), while at the same time they wish to organise and pay for theircommunication completely independently of one another.This “multi-company variant” can be implemented using the OpenCom 510 withina shared office, for example.In the multi-company variant, the companies are essentially completely independentof one another. This allows them to have their own trunk lines, which isuseful for billing purposes. The OpenCom 510 hardware and software are usedequally by all the companies, however. It is possible to configure theOpenCom 510 for each company and define the extent to which the features ofthe system may be used.In brief, the features of the multi-company variant are as follows:■■■■■■■Up to five companies can be configured at the same time.Every user of the OpenCom 510 is assigned to a company.Each available trunk group or SIP account is uniquely assigned to a company sothat incoming external calls can be transferred to the correct internal subscriber.For each company, every route can have its own code. For example, it is possibleto activate different routes with the code “0” for different companies. Thisenables separate charging for outgoing external calls, for example.An individual exchange (“operator”) can be set up for each company.Each company can maintain the communication data of its business partnersin its own company telephone book.The charges can be billed individually for each company.177

Multi-Company VariantConfiguring the Multi-Company Variant17.1 Configuring the Multi-Company VariantThe multi-company variant can be commissioned and configured by the systemadministrator of the OpenCom 510 without any major effort. In the multicompanyvariant, the communications system behaves in exactly the same way asthe single-company variant. This is particularly of interest to users who want toexpand their own system and at the same time operate it in a group.The process in brief:1. The feature must be activated (see Activating the Multi-Company Variantstarting on page 178).2. The required companies must be set up (see Configuring and Managing Companiesstarting on page 179).3. The users of the OpenCom 510 are assigned to the individual companies (seeAssigning Users starting on page 179).4. In order that the OpenCom 510 can transfer incoming calls to the correspondingcompany (or its staff ) correctly, the existing trunk groups must beuniquely assigned to the companies (see Assigning Trunk Groups/SIP Accountsstarting on page 180).5. In the case of outgoing external calls, the lines via which the members of acompany can make a call must be defined (see Allocating Routing Codesstarting on page 180).6. An exchange must be set up for each company so that the OpenCom 510 cancorrectly process statuses in which a call should be routed to the exchange (seeConfiguring the Company Exchange starting on page 181).17.1.1 Activating the Multi-Company VariantTo be able to configure several companies in the OpenCom 510, the “Multicompanyvariant” (OpenCompany 45) program package must first be activated.This is done in the Configurator on the Web console in the SYS Configuration:Licences menu. The licence confirmation you received with the program packagecontains all the information you require about how to proceed.178

Multi-Company VariantConfiguring the Multi-Company VariantOnly when this package has been activated are the fields required to configure themulti-company variant available in the other menus of the Web console, forexample in the User Manager: User groups menu or in the PBX Configuration:Trunks menu.17.1.2 Configuring and Managing CompaniesUp to five companies can be configured in the OpenCom 510. By default, onecompany with the name “Company 1” is predefined. All configuration settings, e.g.in the user groups or in the trunk group configuration, apply to this predefineddefault company if not other company has been selected.Companies are set up and managed in the PBX Configuration: Companiesmenu:■■■A new company is created in this menu using the command New. Eachcompany can be given a name up to 20 characters long. This name is then displayedin all configuration dialogue boxes in which company-specific settingscan be defined.In this menu a company can be deleted again using the command Delete. If acompany is deleted which is still used at other places (in the user groups, forexample), the respective configuration is changed to the default company.The name of the default company can be changed, but the default companyitself cannot be deleted.17.1.3 Assigning UsersFor each user you must define the company to which they belong. Thisassignment determines, for example, which company telephone book the userhas access to and which company-specific configuration data apply to them.As the OpenCom 510 manages users in groups, the assignment “user > company”is also established this way. The company to which each user group belongs mustbe defined for each group. A user group can only belong to one company, i.e. notto several. However, a company can have several user groups. It is therefore possible,in the same way as in the entire system, to allocate a range of authorisationrights for the use and configuration of features for each company.179

Multi-Company VariantConfiguring the Multi-Company VariantWhen setting up a new User group (in the User Manager menu), you will findthat the default company is predefined; another company can be assigned as longas no other companies have been set up.17.1.4 Assigning Trunk Groups/SIP AccountsConnections of the same type and in the same direction are arranged in a trunkgroup (e.g. S 0 multi-terminal connections). To be able to correctly transferincoming calls to the members of the configured companies (the users) via thelines of a certain trunk group of the OpenCom 510, each of the available trunkgroups must be assigned to one of the companies. This is necessary to be able totransfer incoming external calls to the correct company exchange in cases wherethe called internal subscriber cannot be reached (“Connection to Operator”), forexample. SIP accounts can also be assigned to a company.The assignment of trunk groups to companies is done in the PBX Configuration:Trunks: Bundle menu. The assignment of trunk groups to companies is done inthe PBX Configuration: SIP: SIP accounts.For outgoing external calls which users set up via the lines of their company’strunk group/SIP account, the assignment of the trunk group to the company isirrelevant: the charges are assigned according to the “source” principle.Charges are billed to the company to which the user belongs who set up the connection.The OpenCom 510 recognises this on the basis of the assignmentbetween user groups and companies and on the basis of the routing code withwhich a line of the trunk group/SIP account was seized. For more information,please see the following section.17.1.5 Allocating Routing CodesRoutes are used for automatic and selective seizure of trunk groups or connectionsfor external calls. It is possible to seize a route by predialling a code.In the PBX Configuration: Trunks: Route menu, you can define which companycan seize each route. An individual code for the seizure is allocated per route foreach company. The OpenCom 510 ensures that during configuration no seizurecode is allocated twice (for two different routes) for each company. If during configurationof a route no code is allocated for one of the configured companies, theroute concerned cannot be seized by the members (user groups) of this company.180

Multi-Company VariantWorking with the Multi-Company Variant17.1.6 Configuring the Company ExchangeAn internal telephone number must be set up for each company which representsthe exchange, i.e. “the operator”. The calls to specific extensions arriving at theexchange are routed to this number, for example, as are all external calls where thecalled subscriber (a user who belongs to this company) cannot be reached, as inthe case of a timeout.A company exchange is set up in the PBX Configuration: Operator menu. In thismenu, you can specify an internal telephone number for each company and timegroup which then represents the exchange for this company.17.2 Working with the Multi-Company VariantAll the features of the OpenCom 510 which the users may already be familiar withfrom the single-company variant are available in the multi-company variant. Thesefeatures can be used to the same extent and can be used in exactly the same way.The following section describes the features additionally available to the users inthe multi-company variant.17.2.1 Company Telephone BookAn individual company telephone book can be created for each company. Inaddition to this, “personal” and “central” telephone books exist:■■A personal telephone book is available for each user.The central telephone book can be used across the companies by all users ofthe OpenCom 510.The company telephone book is a central telephone book for the whole company.It is only available to the users/user groups who are assigned to this company. Youcan also define whether the members of each user group may edit the companytelephone book or not.The company telephone book is treated exactly the same way on the system terminalsas the other types of telephone books. This means that the entries listed inthe personal, central and company telephone books are displayed on the systemphones at the same time.181

Multi-Company VariantWorking with the Multi-Company VariantUsers can also use the telephone book of their company with the OpenCTI 50Web applications and phone book, assuming they are authorised to use theseapplications.In addition, it is also possible to assign a user group with the authorisation to editforeign company telephone books. This authorisation is useful if members of thisgroup - e.g. the “Administrators” - service the entire system. Foreign telephonebooks can only be edited in the Configurator in the Phone Book menu.The number of entries in a company telephone book is unrestricted. TheOpenCom 510 can manage up to 2,000 entries in all telephone books (in thecentral, personal and company telephone books).17.2.2 Making Calls Between CompaniesAll users of the OpenCom 510 can make internal calls to one another, irrespectiveof which company they belong to. Calls between users from the different companiesare therefore not subject to any restrictions.17.2.3 Billing Charges per CompanyIn the Costs Web application you can output the charges for each company.Users who are authorised to use this application can view the charges for eachcompany.182

Frequently Asked QuestionsGeneral/Hardware20. Frequently Asked QuestionsThis chapter provides tips and information on how to deal with any malfunctionsor faults you may experience with the OpenCom 510.Please note: Repairs to the OpenCom 510 should only be carried out byqualified personnel.The following LEDs indicate that the OpenCom 510 is ready for operation:Activity LEDLAN LED+3,3 VLED-42 VLEDMPS+1-ACMC+1-3Position of LEDs on the OpenCom 51020.1 General/HardwareThe OpenCom 510 is not functioning.Make sure the mains plug is properly connected.Plug another device into the mains socket to check whether there is any voltage.The mains plug is connected, the mains socket is supplying output, but theOpenCom 510 still does not function.DANGER!This device contains hazardous voltages. To make the systemdead, remove the power plug from the socket.Is the +3,3V/-42V LED illuminated?If not, contact your service centre or an authorised dealer. The AC adapter plug ofthe OpenCom 510 may be defective.203

Frequently Asked QuestionsTelephonyAfter restarting the OpenCom 510, nothing is indicated on the displays of anyconnected terminals.It takes a short while for the OpenCom 510 to start up.After the restart, check whether the activity LED flickers in a regularly interval. Thisindicates that the OpenCom 510 has started up correctly and is ready for operation.Further information can be found in the chapter Modules starting onpage 65.If the OpenCom 510 has not restarted properly, reset the OpenCom 510 to itsoriginal factory setting (refer to the chapter entitled Resetting the System Datastarting on page 101).20.2 TelephonyIt is not possible to make external calls.Check the connection between the NTBA and the OpenCom 510.In the Configurator, check whether the external S 0 ports are configured correctly(PBX Configuration: S 0 menu):– Configuration of System- / Multi-terminal access OK?– Port is connected to the NTBA?– Faultless Cabling?– Terminating resistors properly configured?The OpenCom 510 is connected to an NTBA with a multi-terminal configuration.Why is it not possible to establish external connections?With the original factory setting, an additional external S 0 port is set for an NTBA inthe system configuration; this additional port will be used first to seize a trunk line.Deactivate the corresponding S 0 port in the Configurator (PBX Configuration: S 0menu).One of the telephones is not functioning at all.Make sure the telephone has been properly connected.Check also whether the appropriate port has been configured correctly in theConfigurator (PBX Configuration: Ports menu).204

Frequently Asked QuestionsTelephonyIt is not possible to make external calls with one of the telephones.Check whether a user is configured for the telephone. Otherwise the settings ofthe Guests user group are valid for the telephone. To standard, this user group hasno external call authorisation.Make sure the user configured for this telephone belongs to a user group withexternal line access (Configurator, User Manager: User groups menu).Check also whether the internal call number of this telephone has been configuredfor incoming call distribution (Configurator, PBX Configuration: Call Distributionmenu).One of the features (e.g. call diversion) on one of the telephones cannot beused even though the feature has been configured in the Configurator of theOpenCom 510.Make sure the user configured for this telephone belongs to a user group that hasaccess to this feature (Configurator, User Manager: User and User groupsmenus). Some features cannot be used until the system PIN is changed.Nothing is indicated on the display of one of the connected ISDN telephones.You have connected the ISDN telephone to an external S 0 port (RJ-45 socket).These ports are intended for connection to the NTBA only. Connect the telephoneto an internal S 0 port (pressure terminal).Calls can be made but not received with one of the ISDN telephones.The internal call number that has been configured for this ISDN telephone in theConfigurator (PBX Configuration: Ports: S0 menu) must also be configured asan MSN on the ISDN telephone itself. For further information, refer to the UserGuide of your ISDN telephone.An ISDN telephone always rings, if another telephone on the S 0 bus is beingcalled.This case also requires configuring the MSN on the ISDN telephone (see aboveanswer).It is not possible to configure Call Distribution: Outgoing for multi-terminalaccess.You have configured multi-terminal access and system access in parallel. All outgoingcalls are therefore established via system access, and outgoing call distributioncan be configured for system access only (Configurator, Call Distributionmenu).205

Frequently Asked QuestionsDECTA specific MSN can be seized for individual calls by means of a code number procedure.For further information, refer to the “OpenCom 100, Operation onStandard Terminals”user guide.What are some of the causes for problems when sending and/or receivingfaxes?In frequent cases, the reason may be found in a problem with the ISDN-L1 referenceclock distribution. The L1 clock is delivered from the network provider. Anunclean L1 clock distribution and the introduced signalling jitter is overheard bythe human ear. Nevertheless, data and fax transmissions may be disturbed by thejitter. Please check, which ISDN lines will deliver the L1 clock. One of the installedISDN interface boards (MX+S01-8 or MT+S2M1-1) should show a steady greenlight with LED 3. Details can be found under L1 Clock starting on page 153.The fax data transfer possibly is routed via a compressing VoIP connection. Pleaseverify, if the a/b port is configured with the “Fax” setting. For the VoIP connection,select a VoIP profile which includes the non-compressing G.711 codec.20.3 DECTThe LED of the RFP 22/24 base station is flashing, but none of the DECT devicesis functioning.Make sure the terminal setting for the corresponding U pn port is set to RFP 22/24(Configurator, PBX Configuration: Ports: U pn menu).If multiple RFP 22/24 base stations are installed, the blinking LED indicates thatsynchronisation is not finished.The LED of the RFP 22/24 is continuously lit up, but one of the cordless DECTdevices is indicating “No connection”.You have not registered this DECT device. Configure a port in the Configuratorand start the enrolment procedure (PBX Configuration: Devices: DECT Phonesmenu).Is it possible to increase the time for the enrolment procedure?You must manually enter the IPEI of the DECT device in the Configurator. Theenrolment time is then increased to one hour (PBX Configuration: Devices: DECTPhones menu).206

Frequently Asked QuestionsLANAnother manufacturer’s DECT device is not functioning.Check whether the DECT device supports the DECT GAP standard. In the Configurator,also make sure GAP is set for this DECT device (PBX Configuration:Devices: DECT Phones menu).The startup procedure of the RFP 22/24 take a long time? What is the reason?This behaviour may indicate a problem with the reference clock. Refer also to Whatare some of the causes for problems when sending and/or receiving faxes? starting onpage 206.20.4 LANWhy is it not possible to establish a network connection with theOpenCom 510?Check whether the LEDs for the switch and the PC’s network card are indicating aconnection.Check the LEDs for the LAN functions of the OpenCom 510.To check whether there is a network connection with your OpenCom 510, enterthe “ping IP address” command in “Run” in the Windows Start menu (e.g. ping192.168.99.254).How can I determine the IP address of the OpenCom 510?To find out what the IP address is, enter the code number *182 on one ofthe connected system telephones.The code-number procedure *183 also displays the network mask.The network connection is functioning, but nothing is displayed in thebrowser.Enter the complete IP address of the OpenCom 510 along with the protocol identifier,for example http://192.168.99.254/.Check whether the browser has been configured for connection through a proxyserver. If so, deactivate the “Connect through proxy server” setting.207

Frequently Asked QuestionsInternetYou have just configured the OpenCom 510 via the network. Why is it notpossible now to establish a remote data transfer network connection?The network card and the communication (remote data transfer) adapter cannotbe run with the same routing setting. Deactivate the network card before connectingvia the dial-up network.Our network has grown over time, with several segments connected by onecentral router. How can PCs from all segments connect to the OpenCom 510?If several routers are configured for your network in different segments, you canenter extra static routes in the NET Configuration: LAN: Routes menu.In our network the OpenCom 510 dynamically issues the IP addresses byDHCP. Can I firmly assign the IP address for our internal server PCs (mail,Web)?You need a static address assignment for these PCs. Make the appropriate hostassignment entries in the Configurator (NET Configuration: LAN: Hosts menu).Create a static DHCP entry for each host assignment in the NET Configuration:LAN: DHCP Server menu. Activate “Dynamic and static address” for the DHCPserver.20.5 InternetI cannot access our company Web site.Outside your system, your company Web site is accessed at “www.firm.com”, butin the Configurator you have entered “firm.com” as the domain. Your company’ssite URL thus counts as an internal URL and can only be accessed by entering thedirect IP address. If required, change the domain setting in the NET Configuration:LAN menu.Why do some Internet services not work even though they can be used whendialling in directly via a modem?Some Internet services require an active connection coming from the Internet. Butthe configured filter rules prevent this. Plus, it is not possible to establish incomingInternet connections with the PCs directly owing to the network address translationprocess.It is possible to redirect incoming connections in the Configurator, menu NETConfiguration: Port Forwarding. You should secure the redirection target (PC orserver) with a suitable firewall software.208

Frequently Asked QuestionsInternetIt is not possible to access the Internet with the OpenPhone 27.The requirement for this is that the set should be configured as Handset+data.The telephone number used by the OpenPhone 27 to establish an Internet connectionmust also be specified in the respective user profile (Configurator, UserManager: User menu).With the OpenPhone 27, the Internet can be accessed either directly via theremote data transfer network or indirectly via RAS access on the OpenCom 510.For direct access you can directly dial any provider. Indirect access uses the routingfunction of the OpenCom 510, accompanied by the configured security features,for example.Directly via remote data transfer networkIf the Internet is accessed directly via the remote data transfer network, make surethat■■the remote data transfer network is properly installed on your PC and that thecorrect ISP access data is configured,the internal number used by the OpenPhone 27 to establish the data connectionis configured for outgoing call distribution (Configurator, PBX Configuration:Call Distribution: Outgoing menu).Indirectly via RAS accessIf the Internet is accessed indirectly via RAS, the system administrator should makesure that:■■■permission has been given for Internet access via RAS (Configurator, Net Configuration:Firewall menu),an internal number is configured for RAS access (Configurator, Net Configuration:Connections: RAS menu),your user group has been granted RAS access rights (Configurator, UserManager: User Groups menu).For information on the installation of software and on configuring Internet access,refer to the “OpenPhone 26/27” user guide.A SIP connection only passes unidirectional voice. What is the reason?You did not use the OpenCom 510 as internet router or the STUN server of the SIPprovider is unavailable. You need to activate the SIP support at your internet209

Frequently Asked QuestionsInternetrouter, such as “SIP-ALG” or “Full Cone NAT” functions. You can also use theOpenCom 510 for internet access. Correct the STUN setting in the PBX Configuration:SIP Provider menu.Is it possible to use Q.SIG-IP connections via an Internet access with dynamicIP address?Q.SIG-IP connections require a fixed IP assignment for technical and securityreasons. Therefore you need an Internet access with a fixed IP address. It is possibleto tunnel a Q.SIG-IP connection through a VPN connection. A VPN connectionoffers the possibility to determine the peer’s IP address with a DynDNSservice during connection setup. VPN and DynDNS can be realized with externalservers or routers.210
