selected, the DS1 Interface circuit pack takes 41 minutes to recognize and report
a Minor alarm and 41 minutes to recognize and report that a Minor alarm
condition is cleared. If ESF framing mode is selected, the DS1 Interface circuit
pack takes 10 minutes to recognize and report a Minor alarm and 10 minutes to
recognize and report that a Minor alarm condition is cleared.
When the DS1 Interface circuit pack detects a Minor alarm condition, it will send
a MINOR-ALARM message to the maintenance software. After the maintenance
software receives a MINOR-ALARM message, the Minor Alarm Inquiry Test is
initiated to confirm the Minor alarm. All trunks on the circuit pack are kept in the
in-service state after the Minor alarm is confirmed. The Minor Alarm Inquiry Test
is run every 10 minutes until the Minor alarm is cleared.

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 be exhibited.
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.
