TBRI-TRK (Trunk-Side ISDN BRI Channel)
Issue 1 June 2005 2231
Synchronous Commands
You can demand a synchronous outgoing test call by using the following maintenance
commands:
● test trunk grp#/mem# long [repeat number]
● test board location long [repeat number]
● test port location long [repeat number]
Whenever a circuit translates to a trunk-side ISDN-BRI channel during a long test sequence, an
outgoing test call is invoked, and the duration of the test call is 8.6 seconds. Once the test call
completes, the bit error rate is retrieved from the Maintenance/Test Digital Port. A bit error rate
greater than zero is reported as a failure to the Manager I terminal (MGRI). A failure indicates
the need to run further diagnostics.
If no Maintenance/Test circuit pack exists, an outgoing test call over a trunk-side ISDN-BRI
facility is established over a high-speed data channel on the Network Control (NETCON) circuit
pack (DATA-BD).
Asynchronous Commands
Note:
Note: Only one trunk can be tested in a given port network, until the test call is canceled
or completes.

Description / Recommendation
4 ABRT There is a problem with the Processor Interface Link.
1. See the PI-LINK (Processor Interface Link) Maintenance
documentation.
1004 ABRT B channel in use.
1. Enter status trunk to determine whether a call is active on
this trunk-side ISDN-BRI channel.
2. When the service state indicates in-service/idle, retry the test.
1005 ABRT Bad Configuration (that is, no Maintenance/Test circuit pack)
Enter test trunk grp#/mem# and make sure there is a
DATA-CHL (NETCON channel) administered.
1018 ABRT Test call is disabled.
1. Enable Maintenance on the Trunk Group screen.
