    Hardware Reference The termination jumpers (J1 and J2) are normally removed as the building wiring will provide the correct termination for an ISDN TE-to-NT circuit. When the BRI is connected in a point-to-point configuration, J1 and J2 may need to be installed to terminate the line pairs with internal 100Ω resistors. For detailed information, see the Integrated Services Digital Network (ISDN) chapter of the Software Reference or Reference Manual for your switch or router.

    Port Interface Card Hot Swapping the AR040 NSM with PICs The AT-AR040 NSM can be hot swapped with PICs installed in its PIC bays. There is no need to remove the PICs before hot swapping the NSM. When an AR040 NSM with PIC cards is hot swapped out, and an identical combination of AR040 and PICs is hot swapped into the same bay, the software configurations for the PIC interfaces are preserved across the hot swap.

The functionality of all PICs except the AT-AR026 can be checked using the Test Facility software that is built-in to the switch or router, or alternatively, the PIC’s interfaces can be attached to known working networks and devices.
  • Page 28 Port Interface Card loopback requirements. “Loopback Plugs for Testing Interfaces” on page 41 outlines how to construct a loopback plug or cable. To run the Test Facility for a specific interface, use the command: enable test interface={all|base|expansion|ethn|synn|portn| brin|prin|engine|mac|mac0|mac1|mac2} where n is the interface number. To run the Test Facility for all interfaces on a PIC, use the command: enable test interface=exp The tests will run for 4 minutes.

  • Page 29: Cables And Loopback Plugs For Pics

    Hardware Reference Cables and Loopback Plugs for PICs This section describes how to make cables for connecting PIC interfaces to networks, terminals, printers and other devices. How to make loopback plugs for testing PIC interfaces is also described. Transition Cables for the AT-AR023 PIC The synchronous port on the AT-AR023 SYN PIC uses an AMPLIMITE 50-way connector wired as a universal connector to support RS-232/V.28, V.35 and X.21 interface standards in DTE and DCE modes.

  • Page 41: Loopback Plugs For Testing Interfaces

    Hardware Reference Loopback Plugs for Testing Interfaces Loopback plugs are used in conjunction with the Test Facility software to test the physical interfaces on all PICs except the AT-AR026 and AT-AR027 (see the “Test Facility” on page 44 of this Reference, and the Test Facility chapter of the Software Reference).

  • Page 43 Hardware Reference Loopback Plugs for BRI Interfaces If your AR021 (S) BRI-S/T PIC has an MC145474 or MC145574 transceiver, you need a loopback plug to test the BRI interface (Figure 33 on page 43). For other AR021 BRI PICs, you can test the plug without a loopback plug. In this case the Test Facility will still perform an internal loopback test, but this will not test the complete physical interface.

  • Page 44: Test Facility

    Port Interface Card Test Facility The Test Facility is designed to test physical interfaces on all PICs except the AT-AR026. Testing can be performed while the switch or router is operational, but any interfaces being tested are dedicated to the Test Facility. The Test Facility can be thought of as a specialised interface module like PPP or Frame Relay.

  • Page 45: Asynchronous Interface Tests

    Hardware Reference Asynchronous Interface Tests The asynchronous interfaces require a loopback plug to be installed before the test will operate. See “Cables and Loopback Plugs for PICs” on page 29 details of how to make a loopback plug. To start an asynchronous interface test, use the command: enable test int=portn where n is the interface number.

  • Page 46: For More Information

    Port Interface Card If the switch is malfunctioning, reboot it by pressing the recessed Reset button or entering the command restart reboot. Alternatively, power OFF and ON the switch by disconnecting and reconnecting the main power supply (including, if connected, the RPS power). For More Information The Port Interface Card Quick Install Guide outlines the procedure for installing PICs.
