Table 8-539. Test #1213 Far CSU Loop-Back Test — Continued
Error Test
Code Result Description / Recommendation
2000 ABORT Response to the test was not received within the allowable time period. This
may be due to hyperactivity. Error Type 1538 in the error log indicates
hyperactivity. The hyperactive circuit pack is out of service, and one or more of
the following symptoms may be exhibited.
1. The UDS1-BD tests (such as Tests #138 and #139) are aborting with error
2. The tests run on the ports of this circuit pack are returning a no-board
3. A busyout or a release command has no effect on the test results.
4. A list config command shows that the circuit pack and its ports are
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2 FAIL The test failed because it was not set up properly. The UDS1 pack could not
successfully put the far-end CSU into loop-back mode.
1. Rerun the test ds1-loop UUCSS far-csu-loopback-test-begin command.
2. If the test continues to fail, the problem could be with the UDS1-BD board,

properly installed.
NOTE:
When hyperactivity occurs, the circuit pack is isolated from the system,
and all of its trunks are placed into the out-of-service state. The system
will try to restore the circuit pack within 15 minutes. When no faults are
detected for 15 minutes, the UDS1 interface circuit pack is restored to
normal operation. Every UDS1 Interface trunk is then returned to the
in-service state. Hyperactivity is often caused by the associated facility.
In such a case, faults (such as slips, misframes, or blue alarms) would
be entered in the error log. In addition, many hardware errors would be
logged against the associated trunk circuits. If the facility is OK and the
error occurs again after 15 minutes, replace the circuit pack.
the CPE loopback jack equipment, or somewhere between. Run the test
ds1-loop UUCSS cpe-loopback-jack-test-begin command to determine
whether the CPE loopback jack loop-back test is successful. If a CPE
loopback jack device is not being used, issue the test ds1-loop UUCSS
ds1/csu-loopback-tests command instead. If the closer loop-back test
fails, follow the maintenance strategy associated with that test.
