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
will increase the on-board slip counter by 1. 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
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. Ensure that the board translations are correct.
Execute the add ds1 PCSS 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.
This should re-establish the linkage between the internal
ID and the port.
