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 Interface circuit pack detects a Blue Alarm signal from the remote
DS1 endpoint, the circuit pack will transmit a Yellow alarm to the remote DS1
endpoint and send a BLUE ALARM message to the maintenance software. When
the Blue alarm is confirmed, the maintenance software places all trunks of the
DS1 Interface circuit pack into the out-of-service state. The inquiry test will be run
every 10 minutes until the Blue alarm is cleared.
The DS1 Interface circuit pack takes 2 seconds 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 Interface circuit pack stops transmitting
the Yellow alarm and places the trunks back into the service state before the Blue
alarm occurs.
PASS
DS1 signal is present and the physical link is healthy. In addition,
no Integrated CSU errors are detected.

NO
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.
1. Check to ensure that the board translations are correct. Use
the add ds1 UUCSS command to administer the DS1
interface if it is not already administered.
2. If board was already administered correctly, check the error
log to determine if the board is hyperactive. If this is the case,
the 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, issue
the busyout board command.
4. Issue the reset board command.
5. Issue the release busy board command.
6. Issue the test board long command.
This should re-establish the link between the internal ID and the
port.
