So you put in a parallel SONET/TDM infrastructure for volume deployment of
TDM services. 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.
