Call State Audit Test (#257)
This test audits the internal call state by asking the far-end switch for the ISDN call
state. The test is particularly useful when you are trying to clear a hung call. If the
internal call state on the near-end differs from that on the far-end, the call is torn
down.
The ISDN specification allows up to 2 minutes for a reply. If a reply is not received
within the 2 minute window, the test logs a protocol time-out violation against the
associated signaling channel (ATM-DCH, Error Type 1).
NOTE:
PASS simply means that an appropriate message was composed and sent
to the far-end switch.
1114 ABORT Signaling link in transitional state
1. Retry the command up to 5 times at 1-minute intervals.
1116 ABORT Trunk not in Out-of-Service/Far-end state and country protocol

1117 ABORT Service-state audit message outstanding
1. Wait 2 minutes, then try again.
2100 ABORT Could not allocate needed resources
1. Retry the command up to 5 times at 1-minute intervals.
1113 FAIL Signaling link failed
1. See the ‘‘ATM-SGRP (ATM Signaling Group)’’ and
ISDN-LNK (ISDN Signaling Link Port) maintenance objects.
FAIL Internal system error
1. Retry the command up to 5 times at 1-minute intervals.
PASS 1. Wait 4 minutes, then check the Error Log for any new Error
Type 3073.
■
If there are none, 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 request timed out).
