When the Major alarm is cleared, the maintenance software restores all trunks or ports on the
Media Module to their previous service state before a Major alarm occurs.

ABRT Internal system error
1. Retry the command at 1-minute intervals a maximum of 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 Media Module is out of service and one or
more of the following symptoms may be exhibited:
● The MG-DS1 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
MM710 interface Media Module is restored to normal operation. All of the
trunks for the MM710 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.
1. If the facility is OK and the error occurs again after 15 minutes,
replace the Media Module.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals for a maximum of 5 times.
