Error
Code Test Result Description/ Recommendation
None
2100 ABORT System resources required for this test are not available.
1. Retry the command at 1-minute intervals a maximum of 5 times.
FAIL The test failed because the circuit pack did not return the circuit pack code
or vintage.
NOTE:
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 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 result.
4. A list config command shows that the c ircuit pack and the p orts are
properly installed.
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 the command for a maximum of 5 times.
2. If the problem continues, check for hyperactivity. Resolve the problem,
as appropriate.
3. If there is no longer hyperactivity, retry the command for a maximum of 5
times.
4. If the test continues to fail, escalate this problem.
PASS Communication with this circuit pack is successful.
