Yellow Alarm Inquiry Test (#141)
Receiving a Yellow alarm from remote DS1 endpoint indicates th at the remote
DS1 endpoint has an out-of-frame cond ition. The Yellow Alarm Inquiry Test is
used to determine whether the remote DS1 endp oint is transmitting a Yellow
alarm. The DS1 Interface circuit pac k takes 500 msec to recog nize and report a
Yellow alarm and 500 msec to recognize and report that a Yellow alarm condition
is cleared.
When the DS1 Interface circuit pack d etects a Yellow alarm from the remote DS1
endpoint, it will send a YELLOW-ALARM uplink message to th e 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 p laces 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 pac k back to their previous s ervice state before the
Yellow alarm is raised.
This Yellow Alarm corresponds to the yellow F2 state documented in CCITT
recommendation I.431.

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 incorrec t
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 wa s 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 linkage between the internal ID and the port.
