2000 ABORT
PASS
10-688 Issue 4 May 2002
Test
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 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.
A single bit error has been successfully injected into an active
framed 3-in-24 test pattern.
