TBRI-TRK (Trunk-Side ISDN BRI)
Issue 1 May 2002

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 the prescribed 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.

Result Description / Recommendation
1018 ABORT The test is disabled.
1. Enable the test by entering y in the
Maintenance Tests? field on
page 2 of the change trunk-group form.
1019 ABORT An audit is already in progress.
1. Wait two minutes and try again.
1113 ABORT 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 ABORT The signaling link is in a transitional state.
1. Retry the command at 1-minute intervals up to 5 times.
1116 ABORT 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 the
status trunk command.)
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
