Minor Alarm Inquiry Test (#143)
The Minor alarm raised by an MM710 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 MM710 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 MM710 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 MM710 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.

BOARD
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.
be due to incorrect translations, no board is inserted, an incorrect board
is inserted, or an insane board is inserted.
1. Ensure that the board translations are correct. Execute the add ds1
location command to administer the MM710 interface if it is not
already administered.
2. 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.
board is shut down. Reseating the board will re-initialize the board.
3. If the board was found to be correctly inserted in step 1, then enter
the busyout board location command.
4. Enter the reset board location command.
5. Enter the release board location command.
6. Enter the test board location long command.
5. Enter the release board location command.
6. Enter the test board location long command.
This should re-establish the linkage between the internal ID and the port.
