Any  of the Adtran Atlas products.  I have the "baby" - the 550.  There 
is also an 800 and (I think) an 810.  Add a zero to the model number and 
you have a fair idea of the price ;-)

The one I got was the "video-conferencing bundle".  This comes with a 
gazillion cables, the quad ISDN/BRI card, an ISDN/PRI network 
connection, and an ISDN/PRI user connection.  The other stuff we added 
as time went on.  IIRC the Adtran can convert from T-1 signaling to PRI 
signaling and back; it also converts from/to all the various switches 
out there.  It really is a very, very slick box.

It is basically a router for phone numbers, so it has a routing table 
that sends all my faxes to one pair of ISDN BRIs, a bunch of DIDs to the 
PBX, another bunch of fax numbers to the POTS lines for analog faxes, 
etc.  It even lets you  set up "failover" routing - if my PBX goes down, 
all the DIDs are automatically routed to the pre-assigned POTS lines.
