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, 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.

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 a maximum of 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.)

ABORT
Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
