Call State Audit Test (#257)

If a call is active on the trunk, the switches on both sides of the connection should agree on the ISDN
state of the call, as defined in the ISDN Protocol Specification. This test audits internal call state data
by querying the far-end switch as to the ISDN state of the call. It can be helpful when trying to clear a
hung call. If the internal call state data on the near-end switch is different than that of the far-end
switch, then the call will be torn down.
As with Test #256 (Service State Audit), a PASS simply means that an appropriate message was
composed and sent to the far-end switch. The ISDN Specification allows up to 2 minutes for a reply.
If a reply is not received within the 2 minute window, a protocol time-out violation will be recorded
in the error log against the associated signaling channel (ISDN-LNK, Error Type 1).

Description/ Recommendation
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 will automatically retry
every 15 minutes. If the trunk was initially in-service, it is now placed
in the maintenance/far-end state. Incoming calls will be accepted,
but no outgoing calls can be originated. If an incoming call is
presented, another Service State Audit will be immediately
performed in an attempt to put the DS1 ISDN Trunk in the proper
state.
The test could not relate the internal ID to the port (no board). This
could be due to incorrect translations, no board is inserted, an
incorrect board is inserted, or an insane board is inserted.
Ensure that the board translations are correct. Execute the add ds1
GGGVS command to administer the DS1-MM interface if it is not
already administered.
If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the
board is shut down. Reseating the board will re-initialize the board.
If the board was found to be correctly inserted in step 1, then issue
the busyout board command.
Issue the reset board command.
Issue the release busy board command.
Issue the test board long command.
This should re-establish the linkage between the internal ID and the
port.
