DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1005
2000 ABRT 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 test 138 and test 139) 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 has no affect on the test results.
● A list config 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 occurs again after 15
minutes, escalate this problem.
FAIL The remote DS1 endpoint is out-of-service.
1. If the DS1 interface circuit pack connects to a T1 facility, call the
vendor of the T1 carrier to diagnose the remote endpoint.
2. If the DS1 interface circuit pack connects directly to a switch, call the
system technician of the remote switch to diagnose the DS1 endpoint.
1794 FAIL The DS1 Interface circuit pack detects a Line Loopback Alarm (LLB).
1. If the DS1 interface circuit pack connects to a T1 facility, call the
vendor of the T1 carrier to diagnose the remote DS1 endpoint.
2. If the DS1 interface circuit pack connects directly to a switch, call the
system technician of the remote switch to diagnose the DS1 endpoint.
3. If the DS1 interface circuit pack connects directly to a line-side
terminating device (for example, a PRI terminal adapter), call the
vendor of the terminating device to diagnose the equipment.
