I checked out these sites and see teles offering the card for
$159US, which is considerably better than the bitsurfr:

Anyone care to speculate exactly how much work it would be to start
with the existing BISDN driver and one of these cards and get to the
point of having a working ISDN for FreeBSD solution?

Where could one find the protocal specs for "the D channel"?
