With an IDSN line, you have two discrete data channels.  In order to get the 
full bandwidth, you have to have a way to bond them together as a single 
pipeline.  For some reason this was seldom done in the modem, so software on 
the PC was responsible.  I think Microsoft calls it "multilink", others call 
it "channel bonding".  It's included with any software that supports ISDN 
connections.

The fun thing is, it doesn't care what kind of channel you're bonding.  I've 
seen it work with two ISDN channels and two dial-up modems going through two 
different ISP's, all carrying data for the same FTP transfer.
