Slip Alarm Inquiry Test (#144)

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

Description/ Recommendation
No Minor alarm is detected in the MG-DS1 Interface Media Module.
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 MG-DS1 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 use the
busyout board command.
Use the reset board command.
Use the release busy board command.
Use the test board long command.
This should re-establish the linkage between the internal ID and the port.
