Yellow Alarm Inquiry Test (#141)
Receiving a Yellow alarm from a 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 sends 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 or ports
on the circuit pack into the out-of-service state. The Inquiry Test runs every 10
minutes until the Yellow alarm is cleared.
When the Yellow alarm is cleared, the maintenance software restores all trunks or
ports on the UDS1 Interface circuit pack back to their previous service state
before the Yellow alarm was raised.
PASS
No Red alarm is detected on the UDS1 Interface circuit pack.
0
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. Ensure that the board translations are correct. Execute the
add ds1 UUCSS 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.
