Minor Alarm Inquiry Test (#143)
The Minor alarm raised by a DS1 Interface circ uit pack indic ates that the average
bit error rate on the DS1 facility is greater than 1/1,000,000, b ut 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 c ircuit pack takes 41 minutes to recog nize and report
a Minor alarm and 41 minutes to recog nize and report that a Minor alarm
condition is cleared . If ESF framing mode is selected, the DS1 Interface circ uit
pack takes 10 minutes to recog nize and report a Minor alarm and 10 minutes to
recognize and repor t that a Minor alarm condition is c leared.
When the DS1 Interface circuit pac k detects a Minor alarm cond ition, it will send
a MINOR-ALARM message to the maintenance software. After the maintenanc e
software receives a MINOR-ALARM message, the Minor Alarm Inquir y Test is
initiated to confirm the Minor alar m. All trunks on the circuit pac k are kept in the
in-service state after the Minor alarm is c onfirmed. The Minor Alarm Inquiry Test
is run every 10 minutes until the Minor alarm is c leared.
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 incorrec t
board is inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use the add ds1
UUCSS command to administer the DS1 interface if it is not already
administered.
2. If board was alread y administered co rrectly, 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.
