I can't speak for the whole Telco segment, but I work on DSLAMs for a
living and have done so for the past 15 years. Our earliest generation
DSLAMs were ATM based (T1 IMA fed), but within a couple of years
transitioned to Ethernet. Almost all of the equipment that I come in
contact with is Ethernet at this point, but I'm not on the front-lines and
I don't have a lot of exposure to voice services though, but I think it is
safe to say that telcos are vested pretty heavily in Ethernet these days.

I'll have to ask a co-worker about the makeup of the networks he's seen in
the field, but pretty much all the talk I hear about these days is all
Ethernet. I occasionally hear about GR303, SIP and pseudowire ( a tech that
allows for timely delivery of packetized TDM streams primarily for POTS
services).
