UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002 10-1865 555-233-123
If a loss of signal condition co-exists with ICSU and/or echo canceller errors, the
loss of signal condition takes priority, and the board and all trunks on the board
are put in the out-of-service state. Errors are logged, however, for each error type.
When the maintenance subsystem receives notification that the echo canceller
hardware error condition no longer exists, the maintenance subsystem restores
the board and all trunks to their previous service state, if the alarm can be cleared
(no other ICSU errors or loss of signal conditions exist).

Result Description/Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals for 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 has no affect on the test results.
4. 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 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.
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals for a maximum of 5
times.
