Table 535. TEST #143 Minor Alarm Inquiry Test — Continued
Error Test
Code Result
PASS No Minor alarm is detected in the UDS1 Interface circuit pack.
0 NO The test could not relate the internal ID to the port (no board). This could be
BOARD due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
This should re-establish the linkage between the internal ID and the port.
Slip Alarm Inquiry Test (#144)
Slips occur when transmitter and receiver are not running at precisely the same
clock rate. The UDS1 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 that have occurred on a DS1 link.
When the UDS1 Interface circuit pack detects a slip condition, the circuit pack
increments the on-board slip counter by one. A SLIP-COUNT message is
spontaneously sent to the system software after the counter reaches a threshold
(for example, 88). When the maintenance software receives the SLIP-COUNT
message, the Slip Alarm Inquiry Test is initiated to query the slip counters on a
UDS1 Interface circuit pack and total the slip counts in the maintenance software.
If the count of slips is over the threshold, a Minor alarm is raised against the UDS1
Interface circuit pack. All trunks or ports of the UDS1 Interface circuit pack remain
in the in-service state. If the UDS1 Interface circuit pack is used to supply the
system synchronization source, the MINOR alarm will initiate a synchronization
source switch. See
details.

Description/ Recommendation
1. Ensure that the board translations are correct. Execute the add ds1
UUCSS command to administer the UDS1 interface if it is not already
administered.
2. If the board was already administered correctly, check the error log to
determine whether 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, then 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.
