1020 ABORT The DS1 Interface circuit pack is out-of-service.
1. Look for DS1-BD/UDS1-BD errors in the Hardware Error Log. If
present, refer to the appropriate DS1-BD/UDS1-BD (DS1/UDS1 Trunk
Circuit Pack).
2. Retry the command.
2012 ABORT The test was aborted due to an internal system error.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2100 ABORT Could not allocate the necessary system resources for this test.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
2000 FAIL Response to the seizure message was not received within the allowable
time period.
1. Enter the list configuration board UUCSS 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 pac k 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 command at 1-minute intervals for a maximum of 5 times.
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.
FAIL The trunk cannot be seized for an outgoing call. This c ould 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 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 Error Log. If present, refer to
DS1-BD/UDS1-BD (DS1/UDS1 Trunk Circuit Pack).
3. Retry the command at 1-minute intervals for a maximum of 5 times.
