Slip Alarm Inquiry Test (144)
Slips occur when transmitter and receiver are not running at precisely the same
clock rate. The DS1 Interface circuit pack can detect both positive and negative
slips on the DS1 facility. The Slip Alarm Inquiry Test is used to acquire the total
number of slips occurred on a DS1 link.
FAIL The DS1 Interface circuit pack detects a Minor alarm. The DS1 bit error rate
is greater than 1/1,000,000 and less than 1/1000.
1. The performance of DS1 link between DS1 Interface circuit pack and
remote DS1 endpoint is poor. If DS1 Interface circuit pack is TN767,
enter list measurement ds1-log PCSS 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
DS1interface circuit pack connects directly to a switch, call the system
technician of the remote switch to diagnose the DS1 endpoint.
4. Check the physical connection of the DS1 pack and of the cable.
5. Replace the local DS1 interface circuit pack, and repeat the test.
PASS No Minor alarm is detected in DS1 Interface circuit pack.
0 NO 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.
