Minor Alarm Inquiry Test (#143)

The Minor alarm raised by a MG-DS1 Interface Media Module indicates that the average bit error rate on
the DS1 facility is greater than 1/1,000,000, but less than 1/1000. The Minor Alarm Inquiry Test is used
to determine that the received DS1 bit error rate is greater than 1/1,000,000 and less than 1/1000. When
D4 framing mode is selected, the MG-DS1 Interface Media Module takes 41-minutes to recognize and
report a Minor alarm and 41-minutes to recognize and report that a Minor alarm condition has cleared. If
ESF framing mode is selected, the MG-DS1 Interface Media Module takes 10 minutes to recognize and
report a Minor alarm and 10 minutes to recognize and report that a Minor alarm condition has cleared.
When the MG-DS1 Interface Media Module detects a Minor alarm condition, it sends a MINOR-
ALARM message to the maintenance software. After the maintenance software receives a MINOR-
ALARM message, the Minor Alarm Inquiry Test is initiated to confirm the Minor alarm. All trunks or
ports on the Media Module are kept in the in-service state after the Minor alarm is confirmed. The Minor
Alarm Inquiry Test runs every 10 minutes until the Minor alarm is cleared.

Description/ Recommendation
No Major alarm is detected in the MG-DS1 Interface Media Module.
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 MM-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.
