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.
