Talking with the techs working on the DSLAM near my house, this summer, 
all said it was still ATM--and much of what went into the DSLAM was 
brand new.  So someone is still making ATM gear.

Still, it's very clear that the big expense in telco is still that "last 
mile"  Cabinets full of punch-down blocks and wire, wire, wire. Techs 
working for weeks with paper charts, one wire at a time.

I think the cable guys have it easy.
