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 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.

PASS The trunk can be seized for an outgoing call.
