Table 236. TEST #1209 DS1 Board Loopback Test — Continued
Error Test
Code Result
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.
FAIL DS1 Interface circuit pack failed the DS1 Board Loopback Test.
PASS The BLB test executed successfully. The test pattern was transmitted and
received successfully up to the TN767E DS1 board edge.

Description/ Recommendation
1. The DS1-BD tests (such as test 138 and test 139) are aborting with error
code 2000.
2. The tests run on the ports of this circuit pack are returning a no board
result.
3. A busyout or a release command has no affect on the test results.
4. A list config command shows that the circuit pack and the ports are
properly installed.
NOTE:
When hyperactivity occurs, the circuit pack is isolated from the
system, and all of the trunks for this circuit pack 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 DS1
interface circuit pack is restored to normal operation. All of the trunks
for the DS1 interface circuit pack are 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, escalate this problem.
1. Retry test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the BLB test continues to fail, then replace the DS1 circuit pack.
