Blue Alarm Inquiry Test (#139)

The Blue Alarm is a signal sent by the remote DS1 endpoint when it is out-of-service. The Blue
Alarm Inquiry Test checks the blue alarm status of the remote DS1 endpoint.
When the DS1-MM Interface Media Module detects a Blue Alarm signal from the remote DS1
endpoint, the Media Module transmits a Yellow alarm to the remote DS1 endpoint and sends a BLUE
ALARM message to the maintenance software. When the Blue alarm is confirmed, the maintenance
software places all trunks or ports of the DS1-MM Interface Media Module into the out-of-service
state. The inquiry test runs every 10 minutes until the Blue alarm is cleared.
The DS1-MM Interface Media Module takes one second to recognize and report a Blue alarm and 16
seconds to recognize and report the resolution of a Blue alarm. When the Blue alarm is cleared, the
DS1-MM Interface Media Module stops transmitting the Yellow alarm and places the trunks or ports
back into the service state before the Blue alarm occurs.

Line Loopback Alarm

The Line Loopback (LLB) is used by the remote DS1 endpoint to put the DS1 board into a loopback
mode. When the DS1 board is in the LLB mode, the arriving bit pattern is regenerated and sent back.
The Line Loopback (LLB) Alarm activates when the in-band activate LLB bit pattern arrives
continuously for 5 seconds on the DS1 line. The LLB deactivates when the in-band deactivate LLB
bit pattern arrives continuously for 5 seconds on the DS1 line.
Since LLB is a maintenance condition rendering all DS0 channels unavailable for signaling or bearer
traffic, maintenance software treats this the same as a Blue Alarm.

Test Description/ Recommendation
Result
NO The test could not relate the internal ID to the port (no board). This
BOARD 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 DS1-MM 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 issue
the busyout board command.
Issue the reset board command.
Issue the release busy board command.
Issue the test board long command.
This should re-establish the linkage between the internal ID and the
port.
