We've got 40 T1 ADSL customers coming into a single 1.1Mb SMDS connection

Traffic is around %3 to %5 on average with occasional spikes to %50 or
%100 for short periods. Im guessing this behaviour is due to a single PC
at the customers side -- limitations on how much traffic a single user can
generate - how much bandwidth a single stream uses. With a DS3 you could
get perhaps 5,000 to 10,000 "T1" customers is a rough guess. Look at
@Home's model for example.
