Test Description/ Recommendation
Result
ABORT Internal system error
Retry the command at 1-minute intervals a maximum of 5 times.
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 Media Module is out of
service and one or more of the following symptoms may be
exhibited.
The DS1-MM tests (such as Test #138 and Test #139) are aborting
with error code 2000.
The tests run on the ports of this Media Module are returning a no
board result.
A busyout or a release command has no affect on the test results.
A list config command shows that the Media Module and the ports
are properly installed.
When hyperactivity occurs, the Media Module is isolated from the
system, and all of the trunks for this Media Module are placed into
the out of service state. The system will try to restore the Media
Module within 15 minutes. When no faults are detected for 15
minutes, the DS1-MM interface Media Module is restored to normal
operation. All of the trunks for the DS1-MM interface Media Module
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, replace the Media Module.
