Have I selected the wrong card then? They have an incoming E1/ISDN30 line 
going into a prehistoric PBX which they want to replace with a shiny 
new VoIP capable PBX.

All I want to do is some tests beforehand, so in the abscence of a local 
site with an ISDN30 connection to "play" with, I want to connect 2 boxes 
back to back with a TE110p card in each box and a cross-over cable... One 
box will pretend to be the BT exchange, then other the CPE. On the "BT 
exchange" box, I will place a few calls, and have it route them over the 
line to the other box which will answer them (and vice versa)
