There is no such thing as an ATM/WAN interface per se...they just use a box that provides an ATM interface and connect it to a DS3. Note that ATM has a LOT of overhead (like 30%). so ATM over a DS3 is not nearly the bandwidth of using straight HSSI or PTP. ATM is meant as a medium that can be switched at high speed, but as a PTP mechanism it is very poor.
