PUMA T2Technical HandbookGeneral information1.2 TETRA NETWORK OVERVIEWA short overview of the TETRA radio-communication system, the referencestandards adopted, the network infrastructures, the user terminals is here reported.TETRA stands for TErrestrial Trunked RAdio (Trans European Trunked Radio).The TETRA standard, it relies on a thoroughly digital technology and it is able tooffer services and performances not yet available on alternative technologies. Byusing TETRA Networks it is possible to obtain a greater data transmission rate,that is to say that you can send more information in a shorter time. This means thatyou can send longer messages to vehicle drivers or that a greater number ofmobile users can be served under the same system resources. A typical TETRAapplication is the managing of a great number of mobile means, where voice anddata communications can be required as well. On TETRA systems Voice and Datatransmission services are supported by a radio transmission interface which hasthe following main parameters:• Channel spacing: 25 kHz or 12.5 kHz• Modulation: π/4 DQPSK• Gross channel rate: 36 kbits/s (25 kHz channels) or 18 kbits/s (12.5 kHzchannels)• Access mode: TDMA with 4 timeslots (25 kHz) or with 2 timeslots (12.5 kHz)• Transfer rate: 7.2 kbits/s per timeslot• Max transfer rate: 28.8 kbits/s (unsecured transmission)• Transfer rate (secure transmission): up to 19.2 kbits/sAn example of a TETRA system architecture is shown in Fig. 1.1.The main system elements are:• Radio base stations (covering the whole network).• Switching and control units.• Network management system.• User terminals divided in:- hand-held;- vehicular (or motovehicular);- fixed (desktop).P/N: 779-0306/01Revision 03OTE Proprietary information Page 3

PUMA T2Technical HandbookGeneral information1.2.1 TETRA NETWORK EQUIPMENTIn this paragraph, the main characters of the TETRA radio communication systemare briefly described (see Fig. 1.1). Both the equipment of the infrastructure and ofthe terminals are taken into consideration.1.2.1.1 Radio Base Station (BS)The Radio Base Station (BS) is a network element used to realize theelectromagnetic coverage of a certain cell and to guarantee the radio connectionwith the user terminals. Each base station is able to manage many RF carriers;each RF carrier manages four channels.The radiating system of the radio base station is suitably configured depending onthe present requirements.1.2.1.2 Switching and Control Node (SCN)Another element which is part of the TETRA network is the SCN, Switching andControl Node. The system switching capacity are mainly concentrated in the SCN,which, in fact, controls a certain number of radio base stations, dispatch stationsand even other SCNs.Moreover, the SCN, by using an ISI (Inter System Interface), can interface itselfwith other TETRA networks and other external networks (e.g. ISDN, PSTN, PABXetc..) through a gateway.1.2.1.3 Network Management System (NMS)The management of the TETRA network is done through the NMS (NetworkManagement System) which is implemented on a single dedicated station. TheNMS can control a certain number of SCNs and supervise the whole networksystem.1.2.1.4 Control Room Server (CRS)The Control Room Server (CRS) constitutes the interface between the TETRAsystem and the room operators. It manages a certain number of external workingstations connected, for example, through a LAN (Local Area Network).1.2.1.5 WDS, RDS and LDSThere are different types of dispatch stations:• WDS;• RDS;• LDS.The WDS is managed by an operator through a fixed terminal; the connection tothe SCN is guaranteed by a WAN (Wide Area Network).The RDS is the radio dispatch station and it is managed by an operator through aterminal; this time the connection to the system is realized via radio.Page 6 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookGeneral informationThe LDS is directly controlled by the room server and the connection is through aLAN.1.2.1.6 Terminals: fixed stations, vehicular radio and hand-held radioMobile stations are made up of radio terminals which can be divided into vehicularstations and hand-held stations. Both of them can handle concurrent voice anddata transmissions and they can communicate one each other either relying on abase station or not.The fixed station is another kind of radio terminal and it is generally installed insidea radio room.1.2.2 REFERENCE STANDARDThe standards used as a reference in the implementation of TETRAradiocommunication network are the following:• ETS 300 394-1• EN 301 489-18• ETS 300 392-2• ETS 300 396-2P/N: 779-0306/01Revision 03OTE Proprietary information Page 7

PUMA T2Technical HandbookGeneral information1.4 TRUNKED MODE SERVICES1.4.1 Introduction to speech callsSpeech calls are circuit voice connections among network users. They are mainlyclassified as individual and group calls.Both half and full-duplex speech calls are available. The full-duplex call allows theradio unit to speak and listen to at the same time, whereas the half-duplex callallows the radio unit either to speak or to listen in turn.The radio unit user pushes the PTT (Push To Talk) button when he wants to speakissuing thus a request for access to the traffic channel previously assigned to thecall by the system. In a half-duplex call, when permission is granted by the system,only one radio unit user at a time can access the channel. Any PTT contention(simultaneous access requests from different users) is resolved by the systemitself. An indication (audible and visible) is sent by the system to the radio unitwhen the access request to a traffic channel is granted.All group calls are made in half-duplex mode, whereas individual and telephonecalls may be made in half or full-duplex mode.1.4.2 Individual callsAn individual speech call is a bi-directional point-to-point connection between twoterminal units such as Mobile Radio, Dispatcher, or customer’s telephone networkuser. Individual call set-up uses the on/off-hook signalling indication. In this casethe call starts as soon as the called subscriber accepts the incoming call.Individual speech calls may be half or full-duplex. Telephone (interconnect) calls,that is calls to/from PABX users, may be full-duplex whereas the radio unit isequipped with a handset.1.4.3 Talk Group callsA talk group speech call is a point-to-multi-point connection within a subset ofterminal units, such as Mobile Radios, Dispatchers, or telephone user (only ascalling party). All of these will be members of the same talk group and will sharethe same talk group identity. When the group is called, all group members areinvolved in the same call.The radio unit user will start the call by selecting and talking to by means of anopen channel unaware that the open channel service is simulated within theTETRA by means of the TETRA group call service. The radio unit user will actuallyhave to select a group identifier and set-up a group call. Each member of a groupshall be allowed to initiate an “open channel” speech call.An “open channel” group shall always have Late Entry supplementary serviceactivated, in order to allow any radio unit user to enter an ongoing call after theopen channel has been selected by him.Page 10 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookGeneral informationIf a radio unit user calls a group that has already a call in progress, he willautomatically be included in the ongoing call.For talk group calls, only direct set-up signalling is available. Direct set-upsignalling occurs when a radio unit automatically responds to a talk group callwithout any user operation.The TETRA System allocates channels only in cells where group membersactually are.Two types of group calls are supported:• Standard Group Call: this feature is made in half-duplex mode.• All Call “Announcement”: This feature allows the radio unit user to place abroadcast group call to all the radio unit users in the TETRA network. Thecalled radio unit users are only allowed to listen to.Only one traffic channel is allocated for each BS where radio unit users, currentlyattached to the group, are located. The traffic channel is independent of thenumber of radio unit users. The group geographic extension, in terms of basestations involved, is configurable from the NMS.During the call, call parties can leave the call or may lost it (i.e. a party may turn offits radio unit or drive out of the system coverage). Because the TETRA network isnot notified about it, a periodical presence checking is implemented. The TETRAsystem constantly monitors the BS and it release the channel for the BS once ithas determined that all the radio unit users are no longer registered to the BS.Unused channels, found by the presence checking mechanism, are removed fromthe call.Group calls use a hang timer mechanism. Once the transaction is over the call isautomatically released by the network unless a new transmission demand isreceived from a radio unit before the hang time expires. Whenever a newtransmission request is made, the hang timer resets.To join a talk group, the radio unit user selects the pre-programmed group on hismobile equipment by means of the group selector. The radio unit user is then ableto receive any conversation from the group selected.In order to speak, the radio unit user simply makes a call request or a transactionrequest (depending on whether the call is still active or not), to the TETRA system.A call can be released by one of the following two methods:• The radio unit user initiating the call, is allowed to release the call unless adispatcher is participating in the call.• A DC operator is allowed to release any call in which he is participating even ifhe is not the call initiator.Upon PTT activation, and while involved in an ongoing speech call, a radio unitshall issue a speech item request. This request is managed by the TETRA Systemaccording to the radio unit users talking priority privileges.The DC (Dispatching Console) operator is able to interrupt any ongoingtransaction.P/N: 779-0306/01Revision 03OTE Proprietary information Page 11

PUMA T2Technical HandbookGeneral informationTo change the current talk group, the radio unit user is required to detach from thecurrent group and re-attach to the new one. The procedure is performed on air,according to pre-defined TETRA attachment /detachment procedures.On the mobile terminal, the group addresses are assigned to a group selectorwhich is mapped to a related Working Profile Subset (WPS). Up to six WPS,selectable by the radio unit user, are programmed in the mobile terminal thusproviding a maximum of 96 available group addresses.1.4.4 Telephone Interconnect CallTelephone interconnect calls enable the users of the customer’s telephone networkto connect to TETRA users and Talk Groups.Individual calls can be full or half-duplex according to the capability of the TETRAusers equipment.Talk groups connections are always half-duplex. PABX user can be part of the talkgroup only as a calling party, i.e., by dialling into the talk group through the PABXinterface.During a half-duplex interconnect call, the PTT request from the PABX user ismanaged by the SCN PABX interface using voice activity detection.For an incoming call from the PABX gateway to the TETRA System, the connectedSCN can accept either direct or over dialling (see note) during the call set-up.NoteWith over-dialling the PABX user dials the PABX gateway address, whereupon a voice announcementinvites the user to dial the required mobile user address.Regardless of where the user is located in the network, the system infrastructurewill be able to call dialled user.When a TETRA user (individual or group) is called by a PABX user, the completeTETRA seven-digit address identifier must be dialled.DC operator intervention is required to call the radio unit or talk group not havingthe rights to receive automatic telephone interconnect calls.Outgoing calls from the system to the PABX, require the privileged radio unit userto select the telephone interconnect call mode (e.g. by a functional key), and dialthe telephone number.Page 12 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookGeneral information1.5 DATA CALLS1.5.1 Circuit Data ServicesCircuit data service is a feature allowing a user to transfer a virtually unlimitedamount of data to an individual or group identifier.The circuit data service employs traffic channels to establish a switched connectionamong the users.Different data rates are available according to the option of data protection (TETRAcoding) required. The following are the achievable speeds for each slot:• 2.4 kbit/s high data protection• 4.8 kbit/s low data protection• 7.2 kbit/s no data protection.The use of a multi-slot service can involve up to four slots circuit data. Theconnection may only be half-duplex.The equipment shall support single-slot circuit mode data communication in fullduplexmode. Both protected and unprotected data shall be supported with thefollowing bit rates:• 2.4 kbit/s high data protection• 4.8 kbit/s low data protection• 7.2 kbit/s no data protection.During the circuit call set-up, the selected speed and use of data protection mustbe specified.1.5.2 Short Data ServiceThis feature allows a user to transfer limited amounts of data to an individual orgroup identifier over the control channel.Both status messages and short data messages can be sent to/by users alreadyinvolved in a speech call or circuit data call (individual or group call). Themessages are routed over control channels associated with the traffic channelsused by the on-going calls.Short data services are classified as• Pre-defined (status messages) or• User-defined (short data messages).Both services are available between TETRA users (mobile radios anddispatchers).Status messages are pre-defined bit configurations known to both users and thesystem.P/N: 779-0306/01Revision 03OTE Proprietary information Page 13

PUMA T2Technical HandbookGeneral information1.6 PRIORITY GROUP SCANNINGPriority group scanning (PGS) is a mechanism by which a radio unit isprogrammed to simultaneously attach to a list of talk group identities, by assigningeach of them a priority (on a per-user basis) to be used for incoming callmanagement.1.6.1 Class of Usage (CoU) PrioritiesThe class of usage (CoU) value (priority) is generated by the radio unit user anddefines the scan priority associated to a priority group scanning list.CoU values define the scanning priority of the talk groups. The radio unit user setsappropriate CoU values by means of a “CoU updating” utility that can be disabledduring radio unit set-up (by default enabled). All the group identities and CoUvalues of the scanning list are attached by the radio unit as a single message andforwarded to the system. This procedure is carried out whenever a new list isdefined or the PGS mechanism is activated.1.6.2 Scanning AlgorithmWithin the TETRA system, the priority group scanning (PGS) algorithm isimplemented on the radio unit and therefore group call implementation (by thesystem) can be applied even where PGS has been instigated on a radio unit.Page 14 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookGeneral information1.7 OVER THE AIR PROGRAMMING (OTAP)With over the air programming (OTAP), the NMS operator has the facility to reconfigureradio unit databases remotely over the air interface, and to manage andprogram talk group aliases (up to 12 characters). OTAP facilitates the centralisedprogramming of a talk group database in the radio units and allows an easy talkgroup selection on the radio unit.P/N: 779-0306/01Revision 03OTE Proprietary information Page 15

PUMA T2Technical HandbookGeneral information1.8 DIRECT MODE SERVICES1.8.1 Speech CallsDirect mode operation (DMO) is a TETRA operating mode in which two or moremobile stations communicate together without using the switching andmanagement infrastructure. This operating mode is similar to the back-to-backoperation of conventional half-duplex radio schemes used by many existing privatemobile radio systems such as the emergency services.In all direct mode operations a pre-emptive facility is included and it allows higherpriority direct mode radio units to seize the channel from lower priority users. If agateway is included in the call, then it is even possible for a dispatcher to take overthe call.An individual call is a point-to-point communication between one calling party andone called party. It may only be set up between two radio units which haveselected the same DM RF carrier.• RF carrier: The operating DM RF carrier is defined by the frequency relatedto the current position of the group selection rotary knob (the group rotaryknob in fact selects a group identifier and a corresponding carrier frequencyfor each position).• Presence Check: Presence check allows the call initiator to find out whetherthe called party radio unit is switched to the DM RF carrier and responds to aninterrogating message in advance of the call being set up.• Operating mode: The operating mode is simplex (half-duplex on the sameRF carrier).• ON/OFF hook signalling: Unlike TMO, in DMO there is no facility forON/OFF hook signalling. With DMO, response to all calls comes from theradio unit (i.e. there is no facility to wait for the user to go off hook).A Group Call is a two-way point-to-multipoint communication between a callingparty and one or more called parties. It may only be set up between radio units thathave selected the same DM RF carrier.• RF carrier: When the radio unit is working in single attachment mode, theoperating RF carrier is defined by the frequency related to the current positionof the Group rotary knob.When the radio unit is working in multiple attachment mode, the operating RFcarrier is defined for the currently selected Working Profile Subset (WPS); theposition of the Group rotary knob identifies the Talk group to be used for outgoingcalls. The radio unit receives all the active Talk Groups calls using that RF carrier.• Pre-defined Group Number (GTSI): The members of a group have onecommon pre-defined number which is called their Group Number (GTSI) andby which they are addressed. The radio unit air interface uses the addressingPage 16 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookGeneral informationscheme for Group Numbers defined in TMO. The air interface supports morethan one group on a DM RF carrier although only one group is able tocommunicate using the channel at any given time. Only one number (GroupNumber-GTSI) is sent on the air interface and no acknowledgement isexpected.• Operating mode: The operating mode is Simplex.• ID number: The Talking Party Identification is supported but only using the IDnumber: the alias string is not transferred on the DM air interface. When theID number is contained in the radio unit local agenda the alias string isdisplayed.• Late Entry: Late Entry allows a radio when it accesses an active DM RFcarrier to enter an ongoing call if that call is addressed to a group of which it isa member. A radio unit may access a DM RF carrier in a number of ways, forexample:- the user switches on the radio unit and selects that RF carrier- the user switches from another DM RF carrier to that RF carrier- the radio unit returns to DM coverage after a period of lost coverageThe user switches the radio unit from V+D mode to DM and selects that RFcarrier.1.8.2 Short Data ServicesShort Data Services is a feature that enables a user to transfer a limited amount ofdata to an individual or group identifier over the control channel. Short DataServices are classified as:• pre-defined (Status Messages) or• user-defined (Short Data Messages)Status Messages are pre-defined bit configurations known to both users and thesystem.Both Status Messages and Short Data Messages can be sent to or by usersalready involved in speech or circuit data calls (individual or group calls).P/N: 779-0306/01Revision 03OTE Proprietary information Page 17

PUMA T2Technical HandbookGeneral information1.9 EMERGENCY SPEECH CALLThe user can make an emergency call by pressing the emergency red button onthe top of the radio (for at least two seconds) and then the PTT button to speak;the radio must be in the coverage radio area to make the emergency callsuccessfully.The TETRA system makes all the resources available for this kind of call even ifthey are used for other calls. The emergency call is always transmitted at themaximum power. The emergency call is directed to the selected group or to apredefined identifier, and it is the highest priority call: all eventual isofrequencialcalls are terminated.Page 18 OTE Proprietary information P/N: 779-0306/01Revision 03

PUMA T2Technical HandbookTechnical descriptionTransmitter sectionThe base band signal, represented with the two I TX , Q TX components, enters thelinearizer and is converted into a radiofrequency signal.This conversion is permitted by the synthesizer, which is also present in thereceiver section, and allows selecting PLL outputs. This is an important featurebecause it allows frequency changes in frequency adjacent channels.The switch block (LO SW), which is located after the synthesizer, generates thecarrier in the frequency range of the transmission band. This carrier is amplifiedand then enters the linearizer and permits the radiofrequency conversion.After the conversion, the signal, enters the driver RF2105L and the power mosfetamplifier 2SK2974, whose saturated power is 38 dBm in the band of the Hand-heldradio; the output signal (E2) is filtered and after the switch block is sent to theantenna.Receiver sectionThe signal coming from the antenna, enters the switch block then the low noiseamplifier (LNA).Voltages VR1 and VR2 coming out from the DAC RX are used in order to tune theLNA gain.The front end output is mixed by the mixer with the LO1RX RF. The LO1RX isselected by a synthesizer program.The output signal enters the mixer and is converted in the Fifh signal that is filteredby the high-selectivity Fifh filter. Then it is converted in the Fref signal by thesecond mixer, located in the AD607 and it is attenuated by the FI amplifier andfiltered by the Fref filter.At this point it is demodulated by the AD607 and converted into a base bandsignal, represented with the I, Q components.The base band signal components are filtered by the low band filter and sent to theanalogue/digital converter from where they are sent to the base band board.The reference signal coming out of the VTCXO is used as a reference for the PLLand also for the integrated time base.Description of the sections blocks:IQ AMPBuffer and levels’ translator (DC) from 1.5 V to 2.5 V to pilot the linearizer.LINEARIZERThis is a basic device for the transmitter.

PUMA T2Technical HandbookTroubleshootingNow turn on the terminal to be tested; it begins to search and then registers itselfwith its identifier (ITSI), which will appear on the display.When “CALL MOBILE” is pressed, the test set sends a call to the terminal undertest; when the terminal accepts the call, it is possible to check the “MODE” data onthe test set.• Power Profile: ( “Passed” must appear).• Other parameters are (see Table 1.A) “Burst Power” (it can be expressed indBm or mW), “Timing Error” (indicates the number of symbols readerroneously), “Frequency Error” (frequency error) and “Vector Error” [referredto the vector (symbol) transmitted; the mean error (RMS), the peak error(PEAK and the residual error (RESIDUAL) are specified].Even if only one of the parameters does not comply with the ETSI standard (seeTable 1.A), “Passed” does not appear next to “Power Profile”.Tab. 7.1:ParametersPhase Action Expected result1 After the antenna has beendisconnected, connect the terminalto the Tetra Test Set as explained inthis chapter of the manual.None.2 Carry out the necessary settings onthe Tetra Test Set (selection of theTETRA environment, selection oftransmission mode, operatingfrequency, etc.) to pick up thecarrier.3 Check the following on the TetraTest Set:RF powerFrequency errorVector error, mean value (RMS)Vector error, peak valueVector error, residual valueSYS INFO (correct decoding ofsystem data)If the Tetra Test Set settings arecorrect, it receives and demodulates theradio terminal carrier.

PUMA T2Technical HandbookTroubleshootingIn these tests, the TETRA TEST SET simulates the TETRA network.Power TestWhen the “CALL MOBILE” button is pressed on the test set, a call is forwarded tothe terminal being tested.After having pressed the “RF GEN” button, vary the field using the adjustmentknob (see Fig. 7.8), weakening it and thus forcing the terminal to increase thetransmitted power until reaching its MAX power (1 W for portable terminals, 10 Wfor vehicular/fixed terminals). The change in the fluctuating values (in dBm) will benoted in correspondence to “RX GEN LEVEL”.Sensitivity TestThe DYNAMIC SENSITIVITY tests are not carried out in the lab; for this reason,we refer here to STATIC SENSITIVITY.When the “CALL MOBILE” button is pressed on the test set, a call is forwarded tothe terminal under test.After having pressed the “RF GEN” button, use the adjustment knob (see Fig. 7.8)to bring the signal to -112 dBm, starting from a higher value (for example, -90dBm).The call, previously forwarded to the terminal, must remain active up to the value of-112 dBm; to guarantee this, the terminal under test will bring itself to the MAXpower value transmitted (1 W for portable terminals and 10 W for vehicular/fixedterminals).At the end of the test, the operator, besides having carried out the POWER andSENSITIVITY TESTS, also verifies the accuracy of all of the radio terminalparameters.NoteThe POWER and SENSITIVITY TESTS are closely correlated; in fact, the power is controlled by varyingthe sensitivity and vice versa.Fig. 7.8:Adjustment knobP/N: 779-0306/01Revision 03OTE Proprietary information Page 79
