Yep. We have one or two customers on 26AWG at 33,000'. That's cheating a little because we've got a line repeater in the circuit. That was pulling 2.6Mbit and 350k.
We have one or two customers at 21,000' and they have a fairly steady 1.5Mbit/512k running on reach-extended adsl2.
Over 90% of the time our DSL problems are in the last few yards of wiring.
Multi-core wire put into an auto-punchdown demarc (yeah, it has dialtone but the attenuation is so high because you're only just making contact with the wire), splitters into splitters into splitters.
The last thing we have trouble with is load coils on the lines. We've had a few that haven't shown up on the line test equipment, which is usually good down to the last few feet of wire to locate it. That really attenuates DSL. That and waterlogged crimp connections.
Like I'd said, and I think you'll agree, that's what you get when you push something over a line that was never designed for it.
That said, I'm currently running 16.5M down and 2.5M up over copper. I'm 3200' from the office.
