Receiving a Yellow alarm from remote DS1 endpoint indicates that the remote DS1 endpoint 
has an out-of-frame condition. The Yellow Alarm Inquiry test is used to determine whether the 
remote DS1 endpoint is transmitting a Yellow alarm. The DS1 Interface circuit pack takes 
½ second to recognize and report either a:

●

Yellow alarm condition

●

Cleared Yellow alarm condition

When the DS1 Interface circuit pack detects a Yellow alarm from the remote DS1 endpoint, it 
will send a YELLOW-ALARM uplink message to the maintenance software. After the 
maintenance software receives the YELLOW-ALARM message, the Yellow Alarm Inquiry test is 
run to confirm the Yellow alarm. Once the Yellow alarm is confirmed, the maintenance software 
places all trunks on the circuit pack into the out-of-service state. The Inquiry test will be run 
every 10 minutes until the Yellow alarm is cleared.
When the Yellow alarm is cleared, the maintenance software restores all trunks on the DS1 
Interface circuit pack back to their previous service state before the Yellow alarm is raised.

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 add ds1 

location 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 

4. Enter reset board
5. Enter release board
6. Enter test board long

This should re-establish the linkage between the internal ID and the 
port.
