I believe that ATM, even in its perhaps immature state, is useful and cost-effective in a number of applications today. In particular, the cost of wide-area DS-3 ATM services can be very attractive when compared to a number of point-to-point DS-3s. -tjs

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... :) --bill
