Maintenance-Object Repair Procedures
555-233-143 8-1742 Issue 1 May 2002
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 every trunk on the board
is 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’s error condition no longer exists, the maintenance subsystem restores
the board and its trunks to their previous service state, if the alarm can be cleared
(no other ICSU errors or loss-of-signal conditions exist).

Description / Recommendation
ABORT Internal system error
1. Retry the command at 1-minute intervals up to 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 Tests #138 and #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 effect on the test results.
4. A list config command 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 UDS1 interface circuit pack is restored to normal operation. Every
UDS1 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, 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 up to 5 times.
