To use the configuration: • Double-click the connection icon in the HyperTerminal group. When the HyperTerminal window appears, press: • [Enter] a couple of times. The router’s log in prompt will appear.
Hardware Reference 11 All configuration information is stored in flash memory as configuration scripts. these scripts contain standard router commands. When a configuration command is entered at the command prompt from a terminal, terminal emulation program, or Telnet session, the command only alters the dynamic configuration. This is not saved over a power cycle.
AR Router After the self tests are complete, the manager is given the option of forcing a mandatory boot from the EPROM release. The message: Force EPROM download (Y)? is displayed on the terminal connected to the console port (port 0) and the router pauses. If a key is not pressed within a few seconds, the start-up process continues and all steps in the start-up sequence are executed.
Hardware Reference 13 FAIL: RAM presence, invalid PD bits, SIMM 0. ERROR: RAM presence, invalid PD bits, SIMM 1. The presence detect bits for either RAM SIMM stick (Flash memory) had an invalid value. This is fatal for SIMM position 0 and an error for SIMM position 1. If this error occurs then the RAM SIMM stick is not the correct type and should be replaced. The router will function, but with less memory, provided the error occurs in position 1.
AR Router FAIL: BBR test, only 16k bytes found. The BBR size/location test completed, but only the displayed amount of memory was found. This amount is less than the minimum required to run the router software. INFO: Self tests complete. The start-up tests have finished. INFO: Downloading router software. The process of downloading the router software and vector table from ROM is about to begin. ERROR: Code load retried. FAIL: Code load failed. The load of the code from ROM to RAM failed.
Hardware Reference 15 Online Documentation This section provides a step-by-step guide to accessing online documentation. Adobe Acrobat Reader must be installed to view the online documentation. To Access Online Documentation To use the CD-ROM, follow these steps: 1. Insert your router’s Documentation and Tools CD-ROM in the CD-ROM drive. 2. If the Welcome screen does not appear. Select "Run" from the Start Menu (Windows 95, 98, 2000 or NT 4.0). Type d:\start.
AR Router The "Default file transfer directory" field specifies the directory that ATTFTP Server will read from or write to for file requests that do not include a directory specification. To prevent unauthorised access to private directories, enter a path name in the "Restrict to directory" field. AT-TFTP Server will use only the specified directory, even if file requests contain references to other directories. Select "Read only" to prevent files being written to the PC.
Hardware Reference 17 Memory All AR300 Series routers, except the AR390 and AR395, have 8MB of fixed (non-expandable) DRAM. The AR390, AR395, AR410, AR410S, AR720, and AR740 routers have 16MB of fixed (non-expandable) DRAM. The AR725 and AR745 routers have 128MB of SDRAM DIMMs. Other sizes are supported, e.g. 256 and 512MB, see your authorised Allied Telesyn distributor or reseller for upgrade options. Other supplier’s DIMMs are not approved, and therefore not supported, but may function correctly.
AR Router AR300 Series Routers The AR300 Series comprises a family of fixed function routers. Models are distinguished by the type of WAN port on the base CPU card and the number of analogue voice ports supported (Tabl e3 on page 18). Table 3: Interface configurations for AR300 Series routers.

Hardware Reference 33 For a complete description of the analogue voice port features and the commands available to configure the PABX services, see the Software Reference for your router. LAN Ports All models in the AR300 Series, except the AT-AR330, have a single Ethernet 10BASE-T LAN port. The AT-AR330 has two Ethernet 10BASE-T LAN ports. A rear panel slide switch (labelled MDX) allows the user to configure the LAN port(s) for direct connection to either a hub or a personal computer.
AR Router Several grounding options are available for coaxial connectors. The factory default should suit all countries, but the jumper selection in Tabl e14 on page 32 provides flexibility. Normal practice is to ground one end only of each cable, usually the Tx cable. The other end should be left floating or connected via a 100nF capacitor. AR400 Series Routers AR400 Series routers are high-performance broadband routers based around 10BASE-T/100BASE-TX ports.
Hardware Reference 35 The MAC slot can accommodate any one of the following MACs: • AT-AR010 EMAC, Encryption MAC. • AT-AR011 ECMAC, Compression/Encryption MAC • AT-AR011 V2 ECMAC, Compression/Encryption MAC (factory fitted in the AR410S router). • AT-AR012 CMAC, Compression MAC. MACs should only be installed by authorised service personnel. Unauthorised opening of the router lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty.

AR Router Mini Accelerator Cards (MACs) Mini Accelerator Cards (MACs) provide additional processing features or performance, but do not add extra physical interfaces to the router. A MAC can be installed in the dedicated MAC slot (labelled Coprocessor Interface) on all AR300 Series, AR400 Series, and AR720/AR740 routers. MACs should only be installed by authorised service personnel.
Hardware Reference 59 Compression MAC-based compression has the following features: ■ Local 32-bit processor for high speed control and data transfer. ■ Dedicated high performance 32-bit compression hardware. ■ High compression ratio Lempel-Ziv algorithm in hardware. ■ 2 MBytes of history memory. ■ Support for up to 127 compression channels.
AR Router Dual Mode Throughput of an encrypted link can be dramatically increased by using data compression. To support this, ECMACs support both encryption and compression to provide a dual mode which allows combined compression and encryption operations.

AR Router Transition cables can be changed at any time. It is not necessary to power-down the router. When an RS-232 DCE transition cable is connected to a synchronous interface configured to generate clocks, the maximum clock speed is 38400 bps. When an X.21 DCE or V.35 DCE transition cable is connected to a synchronous interface configured to generate clocks, the maximum clock speed is 2 Mbps. Modems and NTUs Modems and NTUs are used to transfer digital information over wide area Telecom links.
Hardware Reference 71 Ethernet Dual 10BASE-T/AUI Interfaces The AT-AR022 ETH PIC has a dual 10BASE-T/AUI Ethernet interface. Only one Ethernet interface type can be active at any one time. The PIC auto-senses which Ethernet interface type is in use. The AUI interface is able to supply the required +12 Volts to attached transceivers. The +12 Volts is fused to prevent any transceiver faults from causing problems with the router.
AR Router Primary Rate ISDN Interfaces Primary Rate ISDN interfaces on the AT-AR390 and AT-AR395 support connection to either 75Ω or 120Ω networks. The 75Ω interfaces conform to the standard BNC method of connection to 75Ω coaxial cable (Table 31 on page 72). Since there is currently no official international standard for “pluggable” connection to a 120Ω system, 120Ω interfaces employ the RJ-45 method of connection used by most other manufacturers (Table 32 on page 72).
Hardware Reference 73 Test Facility A Test Facility designed to test the router’s physical interfaces is built into all AR router software. The test Facility can be thought of as a specialised interface module like PPP or Frame Relay. Although the router can continue to operate normally during specific tests, any interfaces being tested are dedicated to the Test Facility. For more information on the Test Facility’s operation, see the Test Facility chapter of your router’s Software Reference.
AR Router Asynchronous Interface Tests Asynchronous interfaces require a loopback plug to be installed before the test will operate. See “Cables And Loopback Plugs” on page 75 for details of how to make a loopback plug. To start a test of an asynchronous interface, use the command: ENABLE TEST INT=PORTn where n is the interface number. This will run the test for 4 minutes. Use the SHOW TEST command (from the Test Facility chapter of your router’s Software Reference), to observe the test progress.
Hardware Reference 75 Cables And Loopback Plugs This section describes how to make cables for connecting the AR router to networks, terminals, and printers. It also describes loopback plugs, which are required for testing most AR router interfaces. Transition Cables for Network Interfaces AR router synchronous ports use AMPLIMITE 50-way connectors wired as universal connectors to supp/rt RS-232/V.28, V.35 and X.21 interface standards. DTE and DCE modes are supported.
AR Router It is very important that the cables do not degrade EMC emission standards of the router (e.g., FCC, CISPR). The cable foil shield must be connected to the AMPLIMITE metalised backshell with a 360 degree ferrule. In addition, on specified cables, a clip-on cable ferrite must be attached to the cable at the AMPLIMITE end, no more than 25 mm from the rear of the backshell of the AMPLIMITE connector. Contact your authorised Allied Telesyn distributor or reseller for a list of approved ferrites.

AR Router Loopback Plugs for Testing Interfaces Loopback plugs are used in conjunction with the Test Facility software (see the Test Facility chapter) to test the router’s physical interfaces. The purpose of a loopback plug is to connect the output pins on the interface to the input pins so that any data transmitted over the interface is looped back (hence loopback plug) and received at the same interface. On interfaces with control signals, these are also looped back.

Hardware Reference 97 If any MAC tests fail, check that the MAC is correctly installed in its slot and repeat the tests. Contact your authorised Allied Telesyn distributor or reseller if the MAC does not operate correctly. Once the MAC is operating, its functionality can be tested either by using the Test Facility software, which is built into the router, or by configuring a module to use the MAC.
AR Router Installing a PAC PACs can be installed in AR725, AR740, and AR745 routers, one PAC per router. PACs should only be installed by authorised service personnel. Unauthorised opening of the router’s lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty. Before installing a PAC: 1. Check that you have the correct tools and equipment. You will need a medium-sized posidrive screwdriver. 2. Avoid injury by working in a safe environment.

AR Router Testing a PAC There are several ways to check that the PAC is installed and operating correctly. First, check that the router has recognised the card. Turn on the router and enter the command: SHOW SYSTEM to display system information (Figure 61 on page 96). The first part of the display shows details of the cards installed in the router. There should be at least two entries, one for the router base card and one for the PAC. Both the serial number and the part name should be displayed.

AR Router Installing a Flash SIMM Early models of AT-AR720 routers can be upgraded from the factory default 4MB of flash memory to 8MB of flash memory by installing a 4MB 80-way Single Inline Memory Module (SIMM) stick. SIMMs should only be installed by authorised service personnel. Unauthorised opening of the router lid may cause danger of injury from electric shock, damage to the router, and invalidation of the product warranty. Before installing a flash SIMM: 1.

AR Router Replacing Boot EPROMs AR300 Series routers have one boot EPROM and AR720/AR740 routers have two boot EPROMs. Boot EPROMs contain bootstrap code, which loads the main code from a software release file in flash memory. In rare circumstances the boot EPROM(s) may need to be changed. AR725 and AR745 routers do not have boot EPROMs. Boot EPROMs do not need to be replaced, except in rare circumstances. Boot EPROMs should only be replaced by authorised service personnel.
Hardware Reference 109 router base CPU board. Remove the boot EPROMs using the extraction tool. Alternatively, a small flat-bladed screwdriver can be used. If so, gently lever each end of a particular boot EPROM a few millimetres at a time until it comes free. Table 41: Diagrams showing the locations of EPROMs for each router model.
