Ooops, I apologize. I had ISDN myself some years ago, and I was pretty 
sure that upstream and downstream were shared, but I was wrong. Shame on 
me.  :o|

When I got DSL, I ran into the following problem: Whenever I fully 
saturated my upstream bandwith, my downstream speed collapsed. (this was 
mentioned by kami earlier on this thread.) It never happened to me with 
ISDN, and that's why I mixed things up in my memory. The reason why it 
happens with DSL and not with ISDN is that the DSL modem has it's own 
packet queue, and when the queue is full simply drops ACK packets, so 
your TCP connections are throttled. With ISDN, the packet queue is 
managed by the operating system which normally doesn't drop any packets.
