Communication Manager Maintenance Object Repair Procedures
2. A similar relationship exists for the PN Archangel (EAA - the active ATM-EI) and certain
TDM-bus problems. If the EAA is unable to communicate with a port board over the TDM
bus, either the EAA has a fault, the port board has a fault, or there is a problem with the
TDM bus itself. If TDM bus maintenance tests find no problems with the bus, then it is either
the port board or the EAA. It may be simpler to replace the port board than to request a
PNC interchange. However, if it is not clear which port board may be at fault or maintenance
is being performed remotely, verify that the EAA is not at fault by executing a PNC
interchange. If the interchange solves the problem, then the EAA is faulty. If the problem
persists after the interchange, but TDM bus maintenance finds no problem, then the port
board is faulty.
Error Log Entries
Whenever a PNC interchange takes place, an error is logged against PNC-DUP with a code
that conveys information about the cause of the interchange and which PNC became active.
There are no alarms associated with PNC-DUP errors, but there should be an alarm against the
PNC component that caused the interchange. There are no PNC-DUP test sequences, but
status pnc provides information regarding the status of the PNCs. The information in
Table 140: Error Code descriptions and Aux Data correlations and Table 141: Error Log
Encode Field Decoding can help to identify which areas of the Alarm Log to investigate to find
the source of the problem.
