ABRT System resources required for this test are not available.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL The test failed because the circuit pack did not return the circuit pack code
or vintage.
Note: 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 Tests 138 and 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 command has no affect on the test result.
● 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 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.
1. Retry the command up to 5 times.
2. If the problem continues, check for hyperactivity. Resolve the problem,
as appropriate.
3. If there is no longer hyperactivity, retry the command up to 5 times.
4. If the test continues to fail, escalate this problem.
PASS Communication with this circuit pack is successful.
