- (a) 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 has been resolved, the alarm will be retired after a predetermined amount of time.
- (b) This Error Type and Aux Data will occur 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 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 has been resolved, the alarm will be retired after a predetermined amount of time.
- (c) This error type is logged when the port in question is busied out by maintenance personnel. Make sure port is released from busyout via the release port GGGVSpp command.
- (d) This error type indicates that the Media Module has been removed or has been insane for more than 21 minutes. To clear the error, reinsert or replace the Media Module.
- (e) Problems transmitting to the voice terminal. This problem can be caused by defective wiring. Defective wiring 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.
- (f) This is an in-line event that produces this error type when a favorable response is received from running the Digital Line Electronic Power Feed Test (#11). No craft action is necessary. This alarm will be resolved with the passing of time.
- (g) With Aux Data 40963, this error type is a result of an overcurrent condition. With 40988, this error type indicates that the EPF 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 due to "leaky bucket" strategy. If the problem cannot be resolved by one of the steps above, then replace the Media Module.
- (h) An in-line maintenance error has generated an off-board warning due to some 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.
- (i) This indicates that 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 craft action is necessary.
- (j) 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).
- (k) No terminal is connected to the Digital Line board. No maintenance action is required.
- (l) An uplink message has been logged indicating that the Electric Power Feed (EPF) is on with no load on it. No action is necessary.
- (m) 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.
- (n) Internal system error. No action is necessary.
- (o) 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.
