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 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, replace the circuit pack.
FAIL The DS1 Interface circuit pack detects a Major alarm. The DS1 bit error rate is
greater than 1/1000.
1. The performance of DS1 link between DS1 Interface circuit pack and
remote DS1 endpoint is very poor. If the DS1 Interface circuit pack is
TN767, enter list measurement ds1-log PCSS command to read the error
seconds measurement.
2. Verify that both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding.
3. If the DS1 interface circuit pack connects to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 interface
circuit pack connects directly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
4. Check the physical connectivity of the DS1 pack and of the cable.
5. Replace the local DS1 interface circuit pack, and repeat the test.
PASS No Major alarm is detected in DS1 Interface circuit pack.
