If your system has a TN778 PACCON board and "display system-parameters customer-options" has ISDN via PACCON" set to "y" then you don't need a data module and the D channel will be controlled by the PACCON card on the packet bus.
If these items do not exist then you will need a T765 Processor Interface to control the D Channel on the TDM bus and you will have to add a data module with a type of 'procr-intf' with a non-DID extension number. Assign the data module to a physical channel of the TN765 PI board (01 to 04).
Do a 'change communications-interface links' to add the information for the ISDN board. Use the same physical channel as assigned to the data module.
Enable = n
Est Conn = y
PI Ext = Data mod extension number created above
PROT = ISDN
Brd = DS1 circuit pack slot
Identification = Whatever
Do a 'change communications-interface processor-channels' and add an entry:
Appl = ISDN
Link = same as assigned to the data module
Channel = blank
Priority = h
Do a 'add or change signaling-group x.
Associated Signaling = y for Facility Associated Signaling (most likely scenerio)
n for Non-Facility Associated Signaling (another can of worms)
Primary D channel - DS1 circuit pack slot, port 24
Trunk Group = # or leave blank
Go back to the 'change communications-interface links' form and enable the link that you are using.
Give it a few minutes to sync up and then do a 'status signaling-group x'. You should see the primary as 'in-service'
