ISDN-TRK (DS1 ISDN Trunk)
d. 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.
e. 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.
f. 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).
g. This trunk is not recognized by the far-end switch. Investigate the trunk
administration for both switches and make changes as necessary.
h. An unexpected SERVICE or SERVICE ACK was received. Possibilities
include:
i. 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.
j. 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).
