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.
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.
