FAIL The trunk cannot be seized for an outgoing call. This could cause in-line
failures to be reported against the trunk (no answer would report error type
257 with auxiliary data 57487 in the error log).
1. Verify that the Trunk Type field on the trunk administration screen form
matches the trunk type administered on far end switch.
2. Look for DS1-BD/UDS1-BD errors in Hardware Error Log. If present,
refer to the appropriate DS1-BD/UDS1-BD (DS1/UDS1 Trunk Circuit
Pack) Maintenance documentation.
3. Retry the test at 1-minute intervals for a maximum of 5 times.
4. If the test continues to fail, escalate the problem.
2000 FAIL Response to the seizure message was not received within the allowable
time period.
1. Enter the list configuration board PCSS command. If the circuit pack
is a TN767B vintage 8 or 9, a failure of test 314 causes a subsequent
failure of test 7 due to a firmware bug. Eventually, the board and all of
its ports will be taken out of service and extraneous on-board alarms
will be generated. Replace the circuit pack with a TN767C V3 or later.
2. Verify that the ’Trunk Type’ field on the ’Trunk Administration’ screen
matches the trunk type administered on far-end switch.
3. Look for DS1-BD or UDS1-BD errors in the hardware error log. If
present, refer to the DS1-BD (DS1 trunk circuit pack) maintenance
documentation or to the UDS1-BD (UDS1 trunk circuit pack)
maintenance documentation.
4. Retry the test at 1-minute intervals for a maximum of 5 times.
5. If the test continues to fail, escalate the problem.
2053 FAIL At least one of the following errors was found on the DS1 circuit pack: loss
of signal (1281), blue alarm (1793), red alarm (2049), yellow alarm (2305),
or hyperactivity (1537).
1. Look for these error types in the hardware error log and then follow the
procedures given in the maintenance documentation that is
appropriate for the error type that was found.
PASS The trunk can be seized for an outgoing call.
