TBRI-TRK (Trunk-Side ISDN BRI Channel)
Issue 1 June 2005 2229
Call State Audit Test (#257)
This test is nondestructive.
This test performs a call state audit on an ISDN B channel, and upon successful completion,
guarantees that both sides of the interface are in a consistent call state for connections using
the B channel. The test can be helpful when trying to clear a hung call. If the internal call state
data to the near-end switch is different from that of the far-end switch, the call will be torn down.
The test passes if the audit is successful.
The test fails if the board is not inserted, if there is an internal system error, or if a reply was not
received within a certain amount of time.
The test aborts if the signaling link is disconnected, the request is already active, or if the B
channel is in an out-of-service state.

Description / Recommendation
1018 ABRT The test is disabled.
1. Enable the test by entering y in the Maintenance Tests field on page 2
of the change trunk-group screen.
1019 ABRT An audit is already in progress.
1. Wait two minutes and try again.
1113 ABRT The signaling link has failed, so the system cannot send any messages on
behalf of this trunk.
1. Check the results of Test #1251 (Signaling Link State Check).
1114 ABRT The signaling link is in a transitional state.
1. Retry the command at 1-minute intervals up to 5 times.
1116 ABRT The trunk is in an out-of-service ISDN service state.
1. A call cannot be present if the trunk is in an ISDN out-of-service state,
so a call state audit would be inappropriate. No action necessary. (Use
status trunk.)
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the test continues to abort, escalate the problem.
