Problems with optional equipment / 591 P0603534 02Modular ICS 6.1 Installer Guide Problems with optional equipment Analog Terminal Adapter 1. Check the connections to the jack. 2. Check the connections to the ATA. 3. Disconnect the ATA and replace it with a working telephone. If the telephone still works properly, the ICS and/or the station modules (SM) are operating properly. 4. Verify that the programming has been done as described in the Programming Record and the Norstar Analog Terminal Adapter Installation Card . 5. If the trouble seems to be in the ICS or SM, double-check all wiring and programming options. Also refer to Problems with BRI service on page 600 or Data Module down on page 605. OR If the trouble seems to be with the ATA, disable the ATA and replace it with a known working one. Running a Maintenance session to test an ATA 1. Run a Maintenance session to ensure that the ATA is not disabled. See Port/DN status on page 514. 2. Disable the port connected to the ATA using Port/DN status. 3. Enable the port connected to the ATA using Port/DN status.

Problems with optional equipment / 593 P0603534 02Modular ICS 6.1 Installer Guide External paging 1. Use the Button Inquiry feature (≤•‚) to verify the feature of a programmable memory button. 2. Check the wiring between the 50-pin connector and the paging amplifier or between the connections shown in the external paging wiring chart. External paging wiring 3. Test external paging ≤fl¤ to ensure that it is working. The nominal output signal from the Norstar ICS is 100 mV across 600 Ω. Music on Hold/Background Music trouble Although Music on Hold and Background Music are separate features, they share the same wiring and customer-supplied music source. 1. Ensure that the proper feature access code (≤°fl) is turned on. Adjust the volume using the volume control bar. 2. Use the Button Inquiry feature (≤•‚) to verify the feature on a programmable memory button. 3. If there is trouble with Music on Hold or Background Music, check Featr settings in System prgming. 4. Check the wiring between the music source and the 50-pin connector. See Wiring charts on page 252.

Any music source with a low-output impedance, less than 3,300 Ω, can be connected. The output level must be less than one volt. KIM not working The key interface module (KIM) that attaches to a T7316E telephone to create a central answer position (CAP) can be reset in two ways. • If you want to maintain the programming, you can warm start the module by physically unplugging the module from the telephone. When plugged back in, the module will perform a startup. Try this first when you receive an Addon error message on the telephone display. • If you want to restart the module and erase the programming, you can perform one of two cold starts described below. Cold starting the KIM If the KIM does not recover after a warm reset, or if you want to reset the programming for the KIM, there are two types of cold starts for the modules: For both types of cold starts: 1. Unplug and replug the T7316E line cable. The telephone restarts and all the icons flash. When the telephone icons stop flashing, the KIM module icons start flashing.
Problems with optional equipment / 595 P0603534 02Modular ICS 6.1 Installer Guide 2. When the KIM icons start flashing, do one of the following: • KIM single-module cold start If you just want to cold start an individual module, on that module, simultaneously press the two top and two bottom buttons on the lower button set, as shown in the following diagram. The KIM displays a random pattern of icons as the KIM resets. •KIM multi-module cold start If you want to cold start all the KIMs attached to your telephone, simultaneously press the top two buttons on the upper button set, and the bottom two buttons on the lower button set, as shown in the following diagram.
596 / Problems with trunk cartridges service Modular ICS 6.1 Installer GuideP0603534 02 Problems with trunk cartridges service Check first for user problems, then wiring and programming errors before replacing Norstar equipment. 1. Check that the cartridge is properly inserted in the ICS or Trunk Module. 2. Run a Maintenance session to ensure that the cartridge is not disabled. If the problem persists: If the Trunk Cartridge is installed in the ICS and the AC power is present and the LED indicator on the ICS is off, replace the ICS. If the Trunk Cartridge is installed in a Trunk Module: 1. If AC power is present and the LED indicator on the Trunk Module is off, replace the Trunk Module. 2. Replace the fiber cable. 3. Replace the Trunk Cartridge. 4. Replace the Expansion Cartridge. 5. Replace the ICS. Notify service provider of T1 or PRI signaling disruption. Notify your T1 or PRI service provider before disconnecting your T1 or PRI lines, removing power to your system, or performing any other action that disrupts your T1 or PRI signaling. Failure to notify your T1 or PRI service provider may result in a loss of T1 or PRI service.
Problems with trunk cartridges service / 597 P0603534 02Modular ICS 6.1 Installer Guide Refer to Installation on page 219 for information about replacing components. Digital Trunk Interface trouble 1. Run a Maintenance session to verify that the Trunk Cartridge is enabled and that the lines are provisioned. 2.

598 / Problems with trunk cartridges service Modular ICS 6.1 Installer GuideP0603534 02 •Receive Alarm — yellow LED on indicates a problem with the digital transmission being received. This half- duplex link is unusable. •Receive Error — yellow LED indicates a minor error as a result of degraded digital transmission. Possible causes are an ohmic connection, water ingress, or too long a loop. •Transmit Alarm — red LED on indicates an inability to transmit. Alarm indication signal (AIS) is being transmitted to the terminating switch. This half-duplex link in unusable. •Transmit Error — yellow LED on indicates a remote alarm indication (RAI) carrier failure alarm (CFA) is being sent to the terminating switch. If the Transmit Alarm is not on, this indicates a far-end or cable problem. •In service — a flashing green LED indicates that the T1 or PRI trunks are out of service because of a running loopback test, or because the DTI is being initialized. •Loopback test — red LED on while a continuity loopback test is running. •All LEDs flashing continuously — the DTI is being initialized. 3. Run a Maintenance session and any loopback tests as appropriate. 4. Check the pinout of the cable that connects the DTI to the termination point from the T1 or PRI service provider or the external channel service unit, and check that the cable is properly connected. 5. Check with your T1 or PRI service provider to see if through-fed repeaters are used on the T1 or PRI span. The DTI does not provide the DC connection required for through-fed repeaters.
Problems with trunk cartridges service / 599 P0603534 02Modular ICS 6.1 Installer Guide If through-fed repeaters are used on the T1 span, disable the internal CSU and connect the DTI to an external CSU. 6. If the problem persists, replace the DTI. Monitoring the T1 or PRI signal If you are finding minimal faults with the T1 or PRI signal, you can monitor the signal to try and isolate the problem. The monitor jack on the DTI faceplate provides non-intrusive, bridged in-service monitoring of the T1 or PRI signal. Connect a protocol analyzer or other test equipment into the monitor jack to monitor the signal received from the network, and the signal transmitted by Norstar. Notify service provider of T1 or PRI signaling disruption. Notify your T1 or PRI service provider before disconnecting your T1 or PRI lines, removing power to your system, or performing any other action that disrupts your T1 or PRI signaling. Failure to notify your T1 or PRI service provider may result in a loss of T1 or PRI service. Receive signal Transmit signal
600 / Problems with BRI service Modular ICS 6.1 Installer GuideP0603534 02 Problems with BRI service Each LED on front of a BRI-ST or BRI-U Card corresponds with a loop, or indicates an overall state of the BRI connections. The BRI card is connected to the ISDN network (U loop) but the LED for one of more loops is not lit Possible problem The physical connection or configuration for the network connection is not correct (no Layer 1). Solution 1. Verify the wiring from the network to the distribution block. 2. Verify the wiring from the distribution block to the ICS. 3. Use a Meridian 2500 set to test for data on the BRI trunk.
