DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1013
When the Major alarm is cleared, the maintenance software restores all trunks on the circuit
pack to their previous service state before a Major alarm occurs.

ABRT Internal system error
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2000 ABRT 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.
● The DS1-BD tests (such as test 138 and test 139) are aborting with
error code 2000.
● The tests run on the ports of this circuit pack are returning a no board
result.
● A busyout or a release has no affect on the test results.
● 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 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 DS1 interface circuit pack is restored to normal operation. Every
DS1 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, escalate this
problem.
