DS1-BD (DS1 Interface Circuit Pack)
Issue 1 May 2002
8-617555-233-143
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 appear.
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 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 DS1 interface circuit pack detected a yellow alarm sent by the remote DS1
endpoint. An out of frame condition occurred at the DS1 endpoint.
1 FAIL The DS1 Interface circuit pack detects a Remote Multiframe Alarm sent by the
remote DS1 endpoint. An out-of-frame condition occurs on the remote DS1
endpoint.
2 FAIL The DS1 Interface circuit pack is reporting a yellow F5 State alarm. There is a
fault in the user-network interface from the user (PBX) to the network.
1. Verify that both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding. Likewise, verify that any
intermediate CSUs are administered correctly.
2. 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.
3. Check the physical connectivity of the DS1 pack and of the cable.
4. If this continues to fail, escalate this problem.
