UDS1-BD (UDS1 Interface Circuit Pack)
Issue 1 June 2005 2425
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 UDS1 Interface circuit pack takes 500 msec to recognize
and report a Yellow alarm, and 500 msec to recognize and report that the alarm’s condition is
cleared.
Once the alarm is confirmed, the maintenance software places every trunk or port 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 every trunk or port on the
UDS1 Interface circuit pack back to its previous service state before the alarm was raised.
This Yellow alarm corresponds to the yellow F2 state documented in CCITT Recommendation
I.431.
Remote Multiframe Alarm
An RMA (Remote Multiframe Alarm) indicates that the remote DS1 endpoint is in a Loss of
Multiframe Alarm condition while the UDS1 Interface circuit pack is administered using the
DMI-BOS common-channel signaling. The RMA is handled as a Yellow alarm.
0NO
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 translations are correct. Execute add ds1
location 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 so, the board is 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 location
4. Enter reset board location.
5. Enter release board location.
6. Enter test board location long.
This should re-establish the linkage between the internal ID and the port.
