DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 995
2000 ABRT The test was aborted. 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.
● The DS1-BD tests (such as Tests 139 and 140) are aborting with
error code 2000.
● The tests run on the ports of this circuit pack are returning a no board
result.
● A busyout or a release command has no affect on the test results.
● A list config command shows that the circuit pack and the ports
are properly installed.
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 DS1 interface circuit pack is restored to normal operation.
Every DS1 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 recurs after 15 minutes,
escalate this problem.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL DS1 Interface circuit pack failed the Internal Looparound test.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the DS1 Interface circuit pack is a TN767, enter list
measurement ds1-log location to read the error seconds
measurement. Otherwise, skip this step.
3. Verify that both of the DS1 link’s endpoints are assigned with the same
signaling mode, framing mode, and line coding.
4. Check the physical connectivity of DS1 Interface circuit packs and
cable.
5. Contact T1 Network Service to diagnose remote DS1 endpoint.
6. If 2
to 5 are OK and the problem recurs, escalate the problem.
