We are doing this in Manhattan using Adtran TA5000 DSLAMs and Adtran Netvanta SHDSL/EFM bridges. Works great and we're able to deliver up to 40M (8 loops) over standard copper pairs. (Dry unbundled loops)

Don't get me started with SLAs. Verizon in NYC can take 3 days to fix DSL or T1 or even a T3. It's quite sad how bad it's gotten really.

If I can answer anything more specific, let me know.

Take care,

I don't know. Maybe I'm just an old cranky guy, but I think that Ethernet is for LANs and belongs inside and that Carrier is for WANs and belongs outside.

I'm just as old and cranky. I have always called it carrier ethernet. Plug your network connection into a black box and out of the other side comes DSL. Put that on a private line (even with POTS) and use another black box at the other end to connect the DSL to the remote network.

Don't know why the CGs have to make it so complicated. Just call it private DSL. And it is carrier.

DSL covers a wide variety of technologies, being imprecise works fine on the marketing side where you just have a guy that wants to get on the Internet. Most of the EFM gear is a variation on SHDSL that provides symmetrical bandwidth instead of the ADSL products.
