FAIL
The DS1 interface circuit pack detected a slip alarm. The error code equals the
number of slips detected by the DS1 interface circuit pack since the last slip
alarm inquiry test.
1. Retry the command at 1-minute intervals up to 5 times.
2. If the DS1 interface circuit pack is a TN767, enter the list measurement
ds1-log UUCSS command to read the error seconds measurement.
3. Verify that both endpoints and all intermediate equipment of the DS1 link
are administered using the same signaling mode, framing mode, and line
coding.
4. 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 directly to a switch, call the system technician of the
remote switch to diagnose the DS1 endpoint.
5. Check the active alarm and error logs for recent alarms and errors against
the synchronization (SYNC). Follow the suggested repair procedure for
these errors.
6. Check the physical connectivity of the DS1 pack and of the cable.
7. If this continues to fail, escalate this problem.
PASS
No Slip alarm is detected on the DS1 Interface circuit pack.

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. Verify that the board’s translations are correct. Use the add ds1 UUCSS
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 whether the board is hyperactive. If so, the board was shut
down. Reseating the board will re-initialize it.
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.
