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 will send 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
PASS Neither a Yellow alarm nor a Remote Multiframe Alarm
nor a F5 state alarm is being received from the remote
DS1 endpoint.
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. 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.
