DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 1003
Blue Alarm Inquiry Test (#139)
A remote DS1 endpoint sends a blue-alarm signal across the DS1 link when it is out-of-service.
When a local DS1 Interface circuit pack detects a blue alarm from the remote DS1 endpoint, the
circuit pack sends both:
● Periodic yellow alarms to the remote DS1 endpoint
● A BLUE ALARM message to the maintenance software
The Blue Alarm Inquiry test checks the remote DS1 endpoint’s blue-alarm status. After the blue
alarm is confirmed, maintenance software
● Takes every DS1 trunk on the circuit pack out of service
● Runs this test every 10 minutes until the blue alarm is cleared
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. Verify that the board’s translations are correct. Use the add ds1
location 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 whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
3. If the board was found to be correctly inserted in step 1, enter
busyout board
4. Enter reset board
5. Enter release board
6. Enter test board long
This should re-establish the link between the internal ID and the port.
