There is no way that CBR over ATM is economic in the large. And if you are trying to solve a smaller TDM problem, there is lots of good gear that could be wedged into a WDM fabric to deliver smaller volumes. Either way, this use of ATM will not prolong its lifespan. The numbers just do not work. Eric Carroll Tekton Internet Associates
