in dublin the contention is about 4:1 i.e. 3 other people are usuing as
well as yourself.
MCI worldcomm offer a 1:1 contention ratio, but that works out at about
29K per year.
for 512K line not too sure about 128K?
they are the only people who do it, if you push stentor they might as
well. I am led
to believe that contention is a serious thing to consider in factoring
price of lines,
but i'm no expert.

How are leased lines implemented in this country? Frame relay over
fractional T line, or ATM over T line? If contention is a possibility
then it must be ATM right? (frame relay is circuit-switched.. no
contention?)
(or have i got it all backwards and in need of re-reading T.baum's
"computer networks"?) :)
