The minor point that might have been missed is that there is a tradeoff
between point-to-point DS-3s (at 44.7Mbps in clear channel) vs ATM DS-3s
(at 34Mbps w/ ATM framing). Now if I can get four ATM DS3s for less than
I can get 3 point-to-point DS3s, then I can get a win. (raw bandwidth
being about equal... :)
