Minor Alarm Inquiry Test (#143)
The Minor alarm raised by a DS1 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 DS1 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 is cleared. If ESF framing mode is selected, the DS1 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 is cleared.
When the DS1 Interface circuit pack detects a Minor alarm condition, it will send
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 on the circuit pack are kept in the
in-service state after the Minor alarm is confirmed. The Minor Alarm Inquiry Test
is run every 10 minutes until the Minor alarm is cleared.
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. Check to ensure that the board translations are correct. Use the add ds1
PCSS command to administer the DS1 interface if it is not already
administered.
2. If board was 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 link between the internal ID and the port.
