3-580DS1-BD (DS1 Interface Circuit Pack)
3
Remote Multiframe Alarm: Remote Multiframe Alarm (RMA) indicates that the
remote DS1 endpoint is in a Loss of Multiframe Alarm condition while the DS1
Interface circuit pack is administered using the DMI-BOS common channel
signaling. The RMA is handled as a Yellow alarm.
Yellow F5 State Alarm: For 32-channel E1 operation with CRC4 on, the F5 fault
state is defined as a fault in the user-network interface, specifically in the
direction from the user (PBX) to the network. Refer to CCITT recommendation

Error
Code Test Result Description/ Recommendation
ABORT Internal system error
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 5 times.
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 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.
