If you can't get a G.703 card then just get a G.703 to X.21 convertor form
someone like Blackbox.  It might make it easier for you then just doing X.21
to X.21 (you don't have to worry about timeslots!).  Oh, and use the
convertor at the server end as Coax/Cat5 is much cheaper than running a long
X.21 cable!!
