Loss of Signal Alarm Inquiry Test (#138)

This test verifies the synchronization status, echo cancellation, and continuity of the DS1 link. The Loss
of Signal alarm indicates that the MM710 Interface Media Module is unable to derive the
synchronization clock from the DS1 facility. When the MM710 Interface Media Module detects a Loss of
Signal alarm, it stops providing the synchronization clock for the system, if it is administered as a timing
source, and transmits a Yellow alarm to the remote DS1 endpoint.
NOTE:
Synchronization is not administered from the SAT. It is administered via a CLI session
with the G350 Media Gateway Processor.
When the Loss of Signal alarm is confirmed, maintenance software places all trunks or ports of the
MM710 Interface Media Module into the out-of-service state. The inquiry test will run every 10 minutes
until the loss of signal has been restored.
The MM710 Interface Media Module raises a Loss of Signal alarm after the signal has been lost for about
1 second. It will not retire the alarm until the signal has returned for about 10 seconds.

Description/ Recommendation
The Media Module initializes correctly.
Run the Short Test Sequence.
The test could not relate the internal ID to the port (no board). This could
be due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
Ensure that the board translations are correct. Execute the add ds1
GGGVS command to administer the MG-DS1 interface if it is not already
administered.
If the board was already administered correctly, check the error log to
determine whether the board is hyperactive. If this is the case, the board is
shut down. Reseating the board will re-initialize the board.
If the board was found to be correctly inserted in step 1, then use the
busyout board command.
Use the reset board command.
Use the release busy board command.
Use the test board long command.
This should re-establish the linkage between the internal ID and the port.
