I’m going to venture a guess someone got pretty creative for the 9.6 example you mentioned and used the customer payload allocated to the BRI-D channel that is also 9.6 Kb. And then set the card up as D-only ISDN. … Since you’re looking for a 56 Kb DDS could technically run on a B-channel of a BRIU2 could technically carry the data and put it on to the cable pair… I can’t for the life of me figure out an option on the end-user end to treat a 1-b-chanel with no D-channel signaling.
