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, t
he call is torn down.
The test first verifies that the board is physically inserted, gets the current state
from Call Processing, gets the country code, then runs the call state audit.The
test passes if the audit is successful.
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 Test ).
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 not in a service state which is appropriate for running the test.
This test is only performed in the OOS/FE state.
1117 ABORT A service state audit message is outstanding.
1. Wait two minutes and then try again.
2100 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.
FAIL Internal system error
1. Retry the command at 1-minute intervals a maximum of 5 times.
PASS Wait 4 minutes and then check the Error Log for any new errors of type
3073. If there are none, then both sides of the ISDN connection agree on
the service state; the negotiation succeeded. If there is a new 3073 error,
then the negotiation failed (the far-end switch twice failed to respond within
2 minutes). The switch automatically retries every 15 minutes. If the trunk
was initially in-service, it is now placed in the maintenance/far-end state.
Incoming calls are accepted, but no outgoing calls can be originated. If an
incoming call is presented, another Service State Audit is immediately
performed in an attempt to put the TN2185 ISDN Trunk-Side BRI Channel
in the proper state.
