Alarm codes

The Norstar ICS system generates alarm codes after system disconnections or after certain anomalies in system operation. All alarm codes appear at the Alarm telephone and in the System test log of a Maintenance session.

For a more complete description of alarm and event codes, consult your technical support representative. The following figure shows an alarm code appearing on a Norstar Alarm telephone display.

Tips - The Alarm telephone is assigned in Featr settings of system programming.

Alarms have a higher severity than events. Attend to alarm

codes before event messages.

2. If the problem persists, replace Trunk Cartridge Y on DS-30 port X. Refer to the previous table for the definition of X and Y.

 

Alarm: 61-X-Y

1. Check that the proper Trunk Cartridges are inserted in the proper slots of the ICS or Trunk Module.

2. Enter programming and look under the Trk/Line data heading. Check that the Trunk Cartridge type is correctly configured. Alarm codes / 553 Check that the Trunk mode and Answer mode settings do not conflict for every line connected to Trunk Cartridge Y. If Trunk mode is set to unsupervised, Answer mode must be set to manual. OR Install a Trunk Cartridge in slot Y that matches the type of trunk you have configured.

 

Alarm: 62-X-Y

1. Check that the proper Trunk Cartridges are inserted in the proper slots of the Trunk Module.

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. 612 / Problems with trunk cartridges service

Refer to Installation on page 227 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. Check the LEDs on the front of the DTI:

• 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 loop back test, or because the DTI is being initialized.

• Loop back 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.
