Yellow Alarm Inquiry Test (#141)

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 UDS1 Interface circuit pack takes 500 msec to recognize and report a

Yellow alarm and 500 msec to recognize and report that a Yellow alarm condition

is cleared.

When the UDS1 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

PASS No Red alarm is detected on the UDS1 Interface circuit

pack.

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. Ensure that the board translations are correct.

Execute the add ds1 PCSS command to administer

the UDS1 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.

3. If the board was found to be correctly inserted in

step 1, then 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 linkage between the internal

ID and the port.
