Major Alarm Inquiry Test (#142)
The Major alarm raised by a UDS1 Interface circuit pack indicates that the
average bit error rate on the DS1 facility is greater than 1/1000. The Major Alarm
Inquiry Test is used to determine that the received DS1 bit error rate is greater
than 1/1000. The UDS1 Interface circuit pack takes 10 seconds to recognize and
report a Major alarm and 10 seconds to recognize and report that a Major alarm
condition is cleared.
When the UDS1 Interface circuit pack detects a Major alarm, it sends a
MAJOR-ALARM message to the maintenance software. (32-channel interfaces
send a YELLOW alarm to the far end). After the maintenance software receives a
MAJOR-ALARM message, the Major Alarm Inquiry Test is initiated to confirm the
Major alarm on the UDS1 Interface circuit pack. The Inquiry Test runs every 10
minutes until the Major alarm is cleared. The maintenance software places all
trunks or ports on the circuit pack in the out-of-service state if the Major alarm
persists for more than 20 minutes.
When the Major alarm is cleared, the maintenance software restores all trunks or
ports on the circuit pack to their previous service state before a Major alarm
occurs.
PASS Neither a Yellow alarm nor a Remote Multiframe Alarm nor a F5 state alarm
is being received from the remote DS1 endpoint.
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.
