Call State Audit Test (#257)
If a call is active on the port, 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 terminal adapter
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 terminal adapter, the call will be torn down.

Result Description/ Recommendation
1113 ABORT The signaling link has failed, so the system cannot send any messages on
behalf of this port.
1. Check the results of Test #255 (Signaling Link State Check).
1117 ABORT A service state audit message is outstanding.
1. Wait 2 minutes and then try again.
1700 ABORT Rollabout video abort. The PRI terminal adapter associated with this PRI
endpoint extension is detached from the circuit pack. This is a normal abort
when the rollabout video feature is enabled.
1. Either reconnect the disconnected PRI terminal adapter or disable the
rollabout video feature on this circuit pack. To do the latter, enter change
ds1 UUCSS and set the field labeled ‘‘Alarm when PRI Endpoint
Detached?’’ to ‘‘y.’’
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
FAIL Internal system error
1. Retry the command at 1-minute intervals for 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 terminal adapter twice failed to respond within the
mandatory 2-minute window). This switch will automatically retry approximately
every 15 minutes. If the port was initially in the INS (in-service) state, it will now
be placed in the MTC/FE (maintenance, far-end problem) state (refer to the
‘‘Service States’’ section which precedes the PE-BCHL ‘‘Hardware Error Log
Entries and Test to Clear Values’’ table); incoming calls will be accepted, but no
outgoing calls will be originated this port. If an incoming call is presented,
another Service State Audit will be immediately performed in an attempt to bring
the PRI endpoint port the proper state.
