I really don't think that is the case.  Have you seen the news about the new
56kbps technology?  If you read through how that works you will find that
your above scenario isn't normally the case...

I'm not totally sure, but I don't think that ISDN goes up to 100Mbps, which
is what the uni is now supposed to be connected to the internet at.  It used 
to be a 10Mbps half duplex connection until recently.  One of the things that 
supports the idea that the modems are on ISDN is the fact that I almost
always get very consistent Signal to Noise Ratios ranging from 36.4 dB up to
37.1dB.
