Maintenance Object Repair Procedures

The Aux Data values that indicate these sources are identified in the
following table:
If the Aux Data value is in the range 1000-1007, then Packet circuit pack,
port, and endpoint maintenance has been disabled in the EPN due to a
PPN Packet Bus failure. If the value is greater than 1000, then there is also
a failure of the packet Bus in this EPN and the source of the other
information can be determined from the table above.
NOTE:
It is important to remember that problems reported by Packet circuit
packs may be caused by any circuit pack. However, only Packet
circuit packs can detect such problems (inasmuch as TDM-only
circuit packs are not affected by these problems).
h. Packet circuit pack, port, and endpoint maintenance has been disabled due
to more than one circuit pack reporting in-line errors. If this occurs more
than three times in 15 minutes (that is, if maintenance is disabled due to
errors and then re-enabled because no more errors are reported), a Minor
alarm is raised against the Packet Bus. Note that this error may still be
present in the error log even if the “Circuit Pack Audit Test” reports that only
one circuit pack has indicated a problem. This occurs if more than one
circuit pack reported errors with in any one minute interval since the Packet
Bus fault occurred.
NOTE:
Because alarms against a Maintenance Object are not resolved until
all alarming has been cleared, an alarm due to a missing
Maintenance/Test Packet Bus must be cleared by installing a
Maintenance/Test circuit pack before it can be determined if other
Packet Bus alarms have been resolved.
