6 Avaya MultiVantage Software-Controlled Maintenance:
This test, in addition to querying for a loss of signal condition and CSU errors, also queries MM710
to confirm the echo canceller error. A minor alarm is raised if the error is confirmed. The trunks of the
board remain in-service since the board is still functional except for the echo cancellation capability.
If a loss of signal condition co-exists with CSU and/or echo canceller errors, the loss of signal
condition takes priority, and the board and all trunks on the board are put in the out-of-service state.
Errors are logged, however, for each error type.
When the maintenance subsystem receives notification that the echo canceller hardware error
condition no longer exists, the maintenance subsystem restores the board and all trunks to their
previous service state, if the alarm can be cleared (no other CSU errors or loss of signal conditions
exist).
Note: The DSU functionality is not available in this release of AVAYA G700 systems
software.

Test Description/ Recommendation
Result
ABORT Internal system error
Retry the command at 1-minute intervals for 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 (MM710) interface Media Module is restored
to normal operation. All of the trunks for the 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.
ABORT Could not allocate the necessary system resources to run this test.
Retry the command at 1-minute intervals for a maximum of 5 times.
