When running the Short Test Sequence of tests, pay close attention to the
results of the Call State Audit Test (#257).
b. This is a software audit error that does not indicate any hardware
malfunction. Run the Short Test Sequence and investigate associated
errors (if any).
c. The far-end switch changed its ISDN
service state to either out-of-service
or maintenance. This may be a temporary condition due to testing of that
trunk by the far-end
or a hardware problem with the trunk. Outgoing calls
will not be allowed over the trunk. To investigate the status of the trunk,
issue the status trunk <trunk_group/trunk_member> command.
d. This error type indicates that the circuit pack has been removed or has
been insane for more than 11 minutes. To clear the error, reinsert or
replace the circuit pack.
e. These error types indicate a disagreement between this switch and the
switch at the other end of the trunk connection with regard to the ISDN
service state of the DS1 ISDN Trunk. This switch will automatically try to
recover by performing a service state audit. You can use the status trunk
<trunk_group/trunk_member> command to determine the state of the
trunk.
When running the Short Test Sequence, pay close attention to the results
of the Service State Audit Test (#256).
f. This trunk is not recognized by the far-end switch. Investigate the trunk
administration for both switches and make changes as necessary.
g. This error indicates a failure of the DS1/UDS1 Interface circuit pack. When
running the Short Test Sequence, the results of the Signaling Link State
Check Test (#255) are important.
h. Two Service State Audit attempts have failed (see Test #256). The trunks
will not be usable for any outgoing calls (although incoming calls will be
accepted) until the test passes and the trunk state is changed to
in-service (use status trunk trunk_group/trunk_member to investigate
trunk status).
i. Error Type 3585 appears when the switch receives an ISDN RESTART
message for an ISDN trunk. Calls are cleared with the RESTART message.
Therefore, this error type may be associated with a dropped call report
from a user.
The following Aux Data values for Error Type 3585 represent the trunk’s
ISDN call state at the time the unexpected request to restart the channel
was received from the remote switch. This information can be useful if
dropped calls (cutoffs) are being reported by users of the ISDN-PRI
trunks. The meanings of the various Aux Data values are shown below.
Aux Data values of concern; any others can be ignored.
0 A idle trunk received a restart.
