Installation ManualQuidway AR 18 Series RoutersChapter 1 Router OverviewChapter 1 Router Overview1.1 IntroductionQuidway AR 18 Series Routers (hereinafter referred to as AR 18) by HuaweiTechnologies are oriented for SOHO (small office/home office) subscribers. Currentlythe series include 3 sub-series: AR 18-1x, AR 18-2x, AR 18-3x.The five models of AR 18-1x provide diverse WAN (Wide Area Network) ports,including multi-protocol synchronous/asynchronous serial interfaces, backup ports,ISDN BRI S/T and U ports, CT1/PRI ports and E1/CE1/PRI ports. This makes itpossible for the user to flexibly combine the various technologies (such asPSTN/ISDN, FR (Frame Relay), X.25, DDN (Digital Data Network), T1 and E1 line)for networking.The AR 18-2x is Ethernet router, provides Ethernet interface in the upstream direction.The other six models of AR 18-3x, which belong to XDSL routers, provide ADSL ports,G.SHDSL ports or ISDN ports. With one or two subscriber lines, subscribers can beconnected to CO (Central Office) devices (or through a 10BASE-T Ethernet port) forbroadband Internet access. The ISDN port is often used as backup port, but it canalso temporarily serves as uplink port when the ADSL or G.SHDSL port fails. Indownstream direction, they provide four 10/100BASE-T Ethernet ports. Dataswitching between them is Layer 2 (L2) switching, which supports port isolating.With the ports compliant with the international standards. AR 18 Series Routers caninteroperate with the products of other manufacturers on all levels. Thus, theinvestment that the users have made can be protected to a maximum extent.1-1

Installation ManualQuidway AR 18 Series RoutersChapter 2 Installation PreparationChapter 2 Installation Preparation2.1 Requirements on EnvironmentAR 18 series must be used indoors. To ensure the normal operation and prolong theirservice life, the following requirements for installation site must be met.2.1.1 Requirements on Temperature/HumidityCertain requirements on temperature and humidity in the equipment room shall bemet. If the relative humidity is too high, the insulation materials in it will deteriorateeasily or even lead to electric leakage. Sometimes this will result in change to themechanical performance of the materials and rusting of the metal components. If therelative humidity is too low, the fastening screw will become loosen due to shrinkageof the isolation spacer. In an environment with dry climate, the static electricity may beproduced, putting the CMOS of the router to risk. High temperature is of the greatestrisk: for it will significantly degrade the router’s reliability, speed up the aging processof the insulating materials, and shorten the service life of the router. The requirementson the temperature and humidity for AR 18 series are shown in Table 2-1:Table 2-1 Humidity requirements in the equipment roomTemperatureRelative humidity0 o C to 40 o C 10% to 90%2.1.2 Requirements on CleannessDust undermines the normal operation of AR 18 series. Dust dropping on theequipment can cause electrostatic adsorption, which degrades the contactperformance of the metal connectors or connection points. This happens morefrequently when the indoor relative humidity is low, which will not only shorten therouter’s service life, but also cause communication failure.The recommended specification on dust content and particle diameter in theequipment room is shown in Table 2-2:2-1

Introduction to the AUX portAs an RS232-compliant synchronous/asynchronous serial interface, the auxiliary(AUX) port can be used as a secondary WAN port for dial-up. In the event that theconsole port fails, the AUX port can serve as a console port. Refer to Chapter 1Router Overview of this manual for the attributes of the AUX port.II. AUX cableAUX cable is an 8-core shielded cable. One end of the cable is an RJ45 connector forconnecting the console port of the router. The other end is a DB9 (male) connectorand a DB25 (male) connector, whichever can be used to connect the serial interfaceof a Modem, depending on the type of the port.Figure 3-9 AUX cable assembly3-9

Installation ManualQuidway AR 18 Series RoutersChapter 3 Installing the RouterIII. Connecting the AUX cableFollow these steps to connect the AUX cable:Step 1: Plug the RJ45 connector into the AUX port of the router.Step 2: Plug the DB25 or DB9 connector to the serial interface of the analog Modem.In general, the AUX port is used for remote configuration or dial-up backup. In orderto get connected to the remote device, the user should first connect the local Modemto the remote Modem through PSTN..3.7.2 Connecting the Multiprotocol Synchronous/Asynchronous SerialInterfaceI. Introduction to the multiprotocol synchronous/asynchronous serialinterfaceSynchronous/Asynchronous serial interface is usually used for the connection with aWAN device, like a Modem or CSU/DSU (Channel Service Unit/Data Service Unit).Depending on the actual situation, it can work in synchronous/asynchronous mode orDTE/DCE mode. Refer to Chapter 1 Router Overview for its attributes.1) Synchronous/Asynchronous modeThe signaling standards supporting the synchronous and asynchronous modes aredifferent.

For twodevices connected directly, one should operate as DTE, and the other as DCE. TheDCE provides a synchronous clock and specifies the transmission rate, the DTEaccepts the synchronous clock and communicates at the specified transmission rate.Usually, the router serves as a DTE device. To determine whether the deviceconnected to the router is DTE or DCE, see the manual that came with that device.Generally, the asynchronous serial interface is used as a dial-up port when connectedto an external Modem or Terminal Adapter (TA). In this case, it is unnecessary todetermine whether the device is DTE or DCE, and you just need to choose anappropriate baud rate.For the operating mode of the synchronous/asynchronous serial interface, refer toVRP Operation Manual Volume I.II. Synchronous/Asynchronous serial cableThe synchronous/asynchronous serial interface on the router is a DB50 receptacle.Proper connection cable needs to be selected for the applied protocol. By far, 9 typesof synchronous/asynchronous serial cables are available. One end of all the 9 typesof cables is DB50 connector, but the other end (network end) varies with cable type:• V.24 (RS232) DTE cable: DB25 (male) connector• V.24 (RS232) DCE cable: DB25 (female) connector• V.35 DTE cable: 34PIN (male) connector• V.35 DCE cable: 34PIN (female) connector• X.21 DTE cable: DB15 (male) connector• X.21 DCE cable: DB15 (female) connector• RS449 DTE cable: DB37 (male) connector• RS449 DCE cable: DB37 (female) connector3-11

First, according to the transmissionmedium of the WAN, configure the physical operating parameters (e.g., the operatingmode of the serial interface, baud rate and synchronous clock) of the interface. For adial-up port, you need to configure the DCC parameters. Then, configure the linklayer protocol encapsulated on the interface and the related operating parametersaccording to the WAN type.Step 4: Configure the IP addresses or IPX network numbers of all the interfaces onthe router on the basis of subnet division.Step 5: Configure the routes. If it is necessary to start the dynamic routing protocol,you should also configure the related operating parameters for the protocol.Step 6: If security is required, perform the security configuration for the router.Step 7: If reliability is required, perform the reliability configuration for the router.Please see VRP1.7 Operation Manual or VRP3 Operation Manual for detailedintroduction to the protocol and function configurations of the router.4-7

Characteristics of the command line interfaceThe command line interface of Quidway Series Routers has a number ofconfiguration commands, which can be used to configure and manage the routers.The command line interface has the following characteristics:• Performing local configuration through CON port.• Performing local or remote configuration through the telnet command, which canbe used to directly log on and manage other routers.• Implementing configuration on the router through the dumb terminal (here, theterminal refers to the asynchronous port, including the terminal connected toAUX port).• Configuring the hierarchical user protection (includes guest, operator,administrator). Only administrator users are authorized to configure and managethe routers, so that unauthorized users would not be able to intrude the routerillegally.• Users can enter at any time to get online help.• Providing network diagnostic tools, such as Tracert and Ping, to quickly diagnosethe accessibility of the network.• Providing all kinds of detailed debugging information to diagnose network faults.• The command line interpreter adopts fuzzy search for the keywords of thecommand. Thus, you only need to enter the conflict-free keyword for theinterpretation of a command. For example, for the interpretation of a displaycommand, you can just input ”dis”.II. Command line interfaceThe command line interface of Quidway Series Routers provides plenty ofconfiguration commands. Hierarchical user protection is adopted to preventunauthorized users from intruding.In the system view, to facilitate the router management, all the commands aregrouped. Each group associates with a view. Users can use these commands toswitch between different configuration views. Normally, only certain commands canbe executed under a certain configuration mode. But some commands in commonuse (such as ping, display current-configuration, and interface) can be executedin all views.4-8
