FAIL The far-end trunk did not respond to the seizure of the near-end trunk
within the allowable time period. This test could have associated in-line
errors in the error log.
1. 1) Enter the list configuration board UUCSS command. If the circuit
pack is a TN767B vintage 8 or 9, a failure of test 136 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.
2000 FAIL Response to the seizure message was not received within the allowable
time period.

pack is a TN767B vintage 8 or 9, a failure of test 136 causes a

documentation or to the UDS1-BD (UDS1 trunk circuit pack)
Maintenance documentation.
