That's an entirely different thing altogether.  ISDN lines are digital 
from end-to-end.  That's what the "D" stands for.  Even the voice 
channels are digital.  The term "ISDN modem" is incorrect, because there 
isn't actually any demodulating going on.  The term should be "ISDN 
terminal adapter".  It is basically a demultiplexor, not unlike a net card..

But notice that this has only been tested with three very specific 
modems, which are advertised as having voice support.
