Help with PRI/DTI on Option11c

Can some help me with disabling and enabling the D-CH and DTI card on Option 11c. The DCH # is 4. I can' t remember if it's all done in LD 96 or LD 96/LD 60.

And, if he's got a TMDI, he'll need to kill MSDL x

Also, do not re-enable the DCH. If you enable the loop, it should bring up the DCH automatically.

If DTI/PRI type of PRI card, then disable by going to the following loads below and performing the associated commands:

LD 60 STAT [ insert loop (card) number here]. Examine the desired loop/card for the associated D-Channel you need to disable. If you don't know which board has the desired D-Channel then just type in STAT and press enter. then examine the output of the command and look for the D-Channel and card you need.

LD 96 DIS DCH [insert D-Channel Number here] This command will disable the D-Channel for the board.

LD 60 DISL [ insert loop (card) number here] This will disable the DTI/PRI card. But not the Clock controller daughterboard .

** If the DTI/PRI card has an associated Clock Controller daughterboard then don't forget to swap the clock and disable the Clock Controller daughterboard as well.

Commands to disable the Clock Controller daughterboard:

LD 60

SSCK [ insert cabinet number here ] Status for the Clock Controller daughterboard. Usually Cabinet 0 but could be another.

Examine the output of the command. Choose either the secondary source, or Free Run for the next command.

TRCK FRUN 0 This will set Cabinet 0 to Free Run.

DIS CC 0 This will disable the Clock Controller board for Cabinet 0.

SSCK [ insert cabinet number here ] Perform this command once more and ensure the Clock Controller daughterboard for the cabinet is disabled.

After the above steps are completed and verified then you can safely remove The DTI/PRI Card.

Hope This helps.

Better yet read and understand the document "Communication Server 1000M and Meridian 1, Small System Maintenance" chapter on "Replacing equipment". There are procedures on how to perform the actions above. Other chapters as well on "Fault Clearing".
