Error type 0: Run the short test sequence first. If every test passes, run the long test sequence. Refer to each test’s description, and follow its procedures.

Error type 1 with Aux Data 40987: Could be caused by 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 the voice terminal closer to the switch, in terms of feet of wire from the jack to the switch. If the problem persists, replace the circuit pack. Once the problem has been resolved, the alarm disappears after a predetermined amount of time.

Error type 1 with Aux Data 1-20: Occurs when at least 15 off-board problems have been detected with the link to the terminal. 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 the voice terminal closer to the switch, in terms of feet of wire from the jack to the switch). If the problem persists, replace the circuit pack. Once the problem has been resolved, the alarm disappears after a predetermined amount of time.

Error type 18: the port in question is busied out by maintenance personnel. Make sure the port is released from busyout by release port location.

Error type 257: Indicates problems transmitting to the voice terminal, which can be caused by defective wiring. Defective wiring can cause varying degrees of problems on different types of sets.

Error type 513: The result of an ID Request failure to respond to the digital endpoint audit.

Error type 767: An in line event produces this Error type when a favorable response is received from running the Digital Line Electronic Power Feed Test 11. No action is necessary. This alarm will be resolved with the passing of time.

Error type 769 with Aux Data 40963: The result of an unfavorable response to the Digital Line Electronic Power Feed Test 11.

Error type 769 with 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 one hour for the alarm to clear. If the problem cannot be resolved by one of the steps above, replace the circuit pack.

Error type 1025: 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: There is 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 the 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 persists, replace the circuit pack. Once the problem has been resolved, the alarm disappears after a predetermined amount of time.

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

Error type 2305 with Aux Data 32770: The station went off-hook while it was in the ready-for-service state. Use the status station command 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 with Aux Data 40967: 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 the 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 persists, replace the circuit pack. Once the problem has been resolved, the alarm disappears after a predetermined amount of time.

Error type 2817: The endpoint caused a large number of control channel messages to be sent to the switch within a short period of time (50 or more CCMS uplinks within 10 seconds). The station will be taken out-of-service for 30 seconds due to the hyperactivity. This may be completely normal during heavy traffic periods.

Error type 3840 with Aux Data 40965: No terminal is connected to the board. No maintenance action is required. This is also the code that is generated when the link between the circuit pack and the voice terminal is successfully reset. No action is necessary.

Error type 3840 with Aux Data 40989: Indicates an uplink message has been logged indicating that the Electric Power Feed (EPF) is on with no load on it. No action is necessary.

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