(raw bandwidth > being about equal... :) Wide-area DS-3 ATM service can often be cost effective because: o The number of DS-3 local loops is often reduced [For example, three DS-3s connecting three sites require six local loops, while three DS-3 ATM connections require only three local loops.] o DS-3 ATM pricing seems to typically be distance-insensitive. -tjs - - - - - - - - - - - - - - - - -
