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 193: Error Code descriptions and Aux Data correlations
on page 596 and
Table 194: Error Log Encode Field Decoding
on page 597 can help to identify which areas of
the Alarm Log to investigate to find the source of the problem.
