Indeed. It's copper and it might have been put there decades ago. It's like this thoughout most of the former Bell South territory of AT&T and what they are attempting to use to push Uverse through. It's almost always 2 pair twisted copper wire that was optimized over the decades for ~3-4KHz voice bandwidth, sometimes with load coils, ancient connectors, etc. It was OK for DSL in the 1990s. It's a poor performer for VDSL (Uverse) which is hugely dependent upon the state of the wire and distance to the VRAD. They did this because they didn't want to lay new cable.

Because of that VDSL requires a large expensive power hungry VRAD to be installed every few 1000 feet. AT&T has rumored to have stopped installing them. Why I mentioned Edison. His DC system required a power plant to be built every few miles because low voltage DC can't handle distance. AC technology obsoleted that.

I saw that announcement from Bell Labs (actually Alcatel/Lucent). IMO, It will never be implemented in the USA. No US phone company will invest in that tech now. They will go fiber. AT&T has a Gigafiber product, but not in Charlotte. Though I've heard it might be going in in Winston-Salem and maybe parts of Raleigh.

I was thinking more along the lines of the hard line that supplies the pedestals in my neighborhood. In the 16 years I've lived there, TWC has replaced the hardline on my street twice.

And being there's a ped in my yard, I got to see the cable when they pulled it last time. Took them a couple of days to hook up the new distribution box and the cable was laying in the yard.

Glad I didn't touch it. I later learned that high voltage runs down those lines as well. Though I would hope if it was laying in the yard it wouldn't have been energized.
