PE-BCHL (PRI Endpoint Port)
Issue 4 May 2002
10-1221555-233-123
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
about 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 is 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 terminal adapter. The ISDN
Specification allows up to two minutes for a reply. If a reply is not received within
the two minute window, a protocol time-out violation is recorded in the error log
against the associated signaling channel (ISDN-PRI Signaling Link Port, which is
listed in the Error Log as ISDN-LNK; the Error Type is 1).

Result Description/Recommendation
1019 ABORT An audit is already in progress.
1. Wait two minutes and try again.
1113 ABORT The signaling link has failed. As a result, the system cannot
send any messages on behalf of this port.
1. Check the results of Test #255 (Signaling Link State
Check).
1116 ABORT The port is in an out-of-service ISDN service state.
1. A call cannot be present if the port is in an ISDN
out-of-service state. As a result, a call state audit would
be inappropriate, and no action is necessary. (Use the
status pri-endpoint <extension> command to
investigate the ISDN state of the port).
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.
To complete the test on this port, do one of the following:
1. Re-attach the disconnected PRI terminal adapter, or
2. Disable the rollabout video feature on this circuit pack by
entering the change ds1 PCSS command, and set the
field “Alarm when PRI Endpoint Detached?” to “y.”
