Major Alarm Inquiry Test (#142)

The Major alarm raised by a MG-DS1 Interface Media Module indicates that the average bit error rate on
the DS1 facility is greater than 1/1000. The Major Alarm Inquiry Test is used to determine that the
received DS1 bit error rate is greater than 1/1000. The MG-DS1 Interface Media Module takes 10
seconds to recognize and report a Major alarm and 10 seconds to recognize and report that a Major alarm
condition is cleared.
When the MG-DS1 Interface Media Module detects a Major alarm, it sends a MAJOR-ALARM message
to the maintenance software. (32-channel interfaces send a YELLOW alarm to the far end). After the
maintenance software receives a MAJOR-ALARM message, the Major Alarm Inquiry Test is initiated to
confirm the Major alarm on the MG-DS1 Interface Media Module. The Inquiry Test runs every 10
minutes until the Major alarm is cleared. The maintenance software places all trunks or ports on the
Media Module in the out-of-service state if the Major alarm persists for more than 20 minutes.

Description/ Recommendation
Neither a Yellow alarm nor a Remote Multiframe Alarm nor a F5 state
alarm is being received from the remote DS1 endpoint.
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.
