PKT-BUS (Packet Bus)
e. Packet circuit pack, port, and endpoint maintenance has been disabled due
to a packet bus failure. The Aux Data value indicates the cause:

Keep in mind that although only packet circuit packs can detect and report
packet bus problems, such problems can be caused by any circuit pack.
f. 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 a Minor alarm is raised against the packet
bus. This happens when maintenance is disabled due to errors and is then
re-enabled because no more errors are reported.
This error may still be present in the error log even though the Packet
Circuit Pack Audit test (#573) indicates that only one circuit pack is
reporting a problem. This happens when more than one circuit pack has
reported errors in any 1-minute interval since the packet bus fault occurred.
g. The Maintenance/Test packet bus port (M/T-PKT) for this port network is
not in service. This alarm does not appear for EPNs in high-reliability
systems since a TN771D is not required there. The error indicates one or
more of the following:
The TN711 must be installed before other packet bus alarms can be
resolved. (Alarms against a given MO are not resolved until every
alarm-generating condition has been cleared).
555-233-142
Cause
In-line errors from packet circuit packs
Uncorrectable packet bus fault reported by the
Maintenance/Test packet bus port (M/T-PKT)
Both of the above
Packet-related circuit pack, port, and endpoint
maintenance in the EPN has been disabled due to a
packet bus failure in the PPN. The last digit has the same
meaning as the single digits listed above.
The packet bus port has been busied out (indicated by Error Type
18), and a Warning alarm is active against M/T-PKT in the same port
network. Release the port by entering release port UUCSS04.
The packet bus port has failed. Look for alarms against M/T-PKT,
and attempt to resolve these alarms.
The Maintenance/Test circuit pack was not recognized by the
system at the last system restart. Replace the Maintenance/Test
circuit pack.
There is no Maintenance/Test circuit pack in this port network. One
must be installed.
