3-1209UDS1-BD (UDS1 Interface Circuit Pack)
3
This Yellow alarm corresponds to the yellow F2 state documented in CCITT
Recommendation I.431.
Remote Multiframe Alarm
Remote Multiframe Alarm (RMA) indicates that the remote DS1 endpoint is in a
Loss of Multiframe Alarm condition while the UDS1 Interface circuit pack is
administered using the DMI-BOS common channel signaling. The RMA is
handled as a Yellow alarm.
Yellow F5 Fault 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 I.431.

Result Description/ Recommendation
ABORT Internal system error
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 be exhibited.
1. The UDS1-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 UDS1 interface circuit
pack is restored to normal operation. All of the trunks for the UDS1
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.
