Minor Alarm Inquiry Test (#143)
The Minor alarm raised by a UDS1 Interface circuit pack indicates that the
average bit error rate on the DS1 facility is greater than 1/1,000,000, but less than
1/1000. The Minor Alarm Inquiry Test is used to determine that the received DS1
bit error rate is greater than 1/1,000,000 and less than 1/1000. When D4 framing
mode is selected, the UDS1 Interface circuit pack takes 41-minutes to recognize
and report a Minor alarm and 41-minutes to recognize and report that a Minor
alarm condition has cleared. If ESF framing mode is selected, the UDS1 Interface
circuit pack takes 10 minutes to recognize and report a Minor alarm and 10
minutes to recognize and report that a Minor alarm condition has cleared.
When the UDS1 Interface circuit pack detects a Minor alarm condition, it sends a
MINOR-ALARM message to the maintenance software. After the maintenance
software receives a MINOR-ALARM message, the Minor Alarm Inquiry Test is
initiated to confirm the Minor alarm. All trunks or ports on the circuit pack are kept
in the in-service state after the Minor alarm is confirmed. The Minor Alarm Inquiry
Test runs every 10 minutes until the Minor alarm is cleared.
PASS No Major alarm is detected in the UDS1 Interface circuit pack.
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 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.
