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
FAIL The DS1 Interface circuit pack detects a Major alarm. The DS1 bit error rate is
greater than 1/1000.
1. The performanc e of DS1 link between DS1 Interface c ircuit pack and
remote DS1 endpoint is very poor. If the DS1 Interface circuit pack is
TN767, enter list measurement ds1-log UUCSS command to read the
error seconds measurement.
2. Verify that both endpoints of the DS1 link are administered using the same
signaling mode, framing mode, and line coding.
3. If the DS1 interface circuit pack connects to a T1 facility, call the vendor of
the T1 carrier to diagnose the remote DS1 endpoint. If the DS1 interface
circuit pack connects d irectly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
4. Check the physical connectivity of the DS1 pack and of the cab le.
5. Replace the loc al DS1 interface circ uit pack, and rep eat the test.
PASS No Major alarm is detected in DS1 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. 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 alre ady administered c orrectly, check the error log t o
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.
