Error type 0: Run the short test sequence first. If every test passes, run the long test sequence.

Error type 1, Aux Data 40987: Could indicate a noisy port or link. This is an off-board problem detected by the port circuit. Check for defective wiring, a defective voice terminal, or move voice terminal closer to the switch in terms of feet of wire from the jack to the switch. If the problem still exists, replace the media module. Once the problem is resolved, the alarm is retired after a predetermined amount of time.

Error type 1, Aux Data 1 - 20: Occurs when at least 15 off-board problems with the link to the terminal have been detected. When an error with the link is detected, an on-board counter is incremented.

The user could experience a noisy port or link. This is an off-board problem detected by the port circuit. Check for defective wiring, a defective voice terminal, or move voice terminal closer to the switch in terms of feet of wire from the jack to the switch. If the problem still exists, replace the media module. Once the problem is resolved, the alarm is retired after a predetermined amount of time.

Error type 18: The port in question is busied out by maintenance personnel. Use release port location to release the port from busyout.

Error type 130: The media module has been removed for more than 21 minutes. To clear the error, reinsert or replace the media module.

Error type 257: Problems transmitting to the voice terminal. This can be caused by defective wiring, which can cause varying degrees of problems on different types of sets. Sets such as the 7410 appear to be more susceptible to wiring problems than other sets. This is usually an on-board problem and can be ignored if no user complaints are received.

Error type 767: A favorable response was received from running the Digital Line Electronic Power Feed Test 11. No action is necessary. This alarm is resolved with the passing of time.

Error type 769, Aux Data 40963: An unfavorable response was received from the Digital Line Electronic Power Feed Test 11. See the test for repair procedures.

Error type 769, Aux data 40988: The EPF/PTC circuit has been turned off due to an overcurrent condition.

Once the problem has been resolved, it may take up to 1 hour for the alarm to clear. If the problem cannot be resolved by one of the previous steps, then replace the media module or media module.

Error type 769, Aux Data 40989: The Communication Manager software sends an EPF query to the port board for a particular port. The board returns the failure message 40989. This means that the power for this particular port is not working. As a recovery strategy, you may busy out or release the port and then re-test the port. However if the failure still continues, replace the board.

Error type 1026: There is a problem with the voice terminal EEPROM. When the voice terminal is repaired the alarm will be resolved with the passing of time.

Error type 1537: An off-board warning was generated due to a problem with the link to the voice terminal. This can be ignored if no user complaints are received. Otherwise, make sure the voice terminal is connected, check for defective wiring, check for a defective voice terminal, and move voice terminal to a jack that is closer to the switch in terms of feet of wiring between the jack and the switch. If the problem still exists, replace the media module. Once the problem has been resolved, the alarm will be retired after a predetermined amount of time.

Error type 2304: Internal system error. No action is necessary.

Error Type 2305, Aux Data 32770: This indicates that the station went off-hook while it was in the ready-for-service state. Use status station to determine the state of the station. The off-hook should have moved the station to ready-for-service. No action is necessary.

Error Type 2305, Aux Data 40967: An off-board warning was generated due to some problem with the link to the voice terminal. This can be ignored if no user complaints are received. Otherwise, ensure the voice terminal is connected, check for defective wiring, check for a defective voice terminal, and move voice terminal to a jack that is closer to the switch in terms of feet of wiring between the jack and the switch. If the problem still exists, replace the media module. Once the problem has been resolved, the alarm will be retired after a predetermined amount of time.

Error type 2817: Port Level Hyperactivity. Fifty or more CCMS uplink messages were received from the port within ten seconds. The user is taken out of service for a short interval of time default 30 seconds.

Error type 3073: This error occurs when Communication Manager sends a query to the endpoint for the serial number and the endpoint does not respond. Communication Manager sends this query to the endpoint periodically and during endpoint initialization.

Error type 3585: An attempt to execute a firmware download of a DCP terminal has failed. The DCP terminal must be replaced before the firmware download can be executed successfully. Replace the DCP terminal and re-execute the firmware download.

Error type 3840, Aux data 40965: No terminal is connected to the Digital Line board. No maintenance action is required.

Error type 3840, Aux Data 40989: The Electric Power Feed (EPF) is on with no load on it. No action is necessary.

Error type 3841: The media module’s message buffer is full. This may be caused by having many display phones with heavy traffic connected to the media module. No action is necessary.
