Avaya 03-300430 User Manual

●

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 location04.

●

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.

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).

Investigate tests in the order presented below. Clearing Error Codes associated with the one 
test may also clear errors generated from other tests in the sequence.

This test queries the Maintenance/Test packet bus port about the state of health of the packet 
bus. If the Maintenance/Test circuit pack indicates that the packet bus has faults, the test fails. 
The corresponding failure code describes the severity, type, and number of faults. The test 
passes if the packet bus is fault-free.

Note:

A Maintenance/Test circuit pack is usually absent from a standard-, duplex-, or 
high-reliability system’s PNs. However, customers may optionally install a 
Maintenance/Test circuit pack both to utilize its enhanced analog-trunk and 
digital-line testing capabilities and to enhance the system’s ability to quickly 
recognize a packet bus failure.
