Slip Alarm Inquiry Test (#144)

Slips occur when transmitter and receiver are not running at precisely the same clock rate. The DS1-
MM Interface Media Module 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 DS1-MM Interface Media Module detects a slip condition, the Media Module 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 DS1-MM Interface Media Module 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 DS1-MM Interface
Media Module. All trunks or ports of the DS1-MM Interface Media Module remain in the in-service
state.

Description/ Recommendation
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.
Ensure that the board translations are correct. Execute the add ds1
GGGVS command to administer the DS1-MM interface if it is not
already administered.
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.
If the board was found to be correctly inserted in step 1, then issue
the busyout board command.
Issue the reset board command.
Issue the release busy board command.
Issue the test board long command.
This should re-establish the linkage between the internal ID and the
port.
