Thanks for the inso...
So T1 lines in the United States also use copper lines from the company to
the telephone exchange in some installations?
What's the benefit to the subscriber to this?

Any T1 I've seen in the last 3 years has actually been DS1-over-HDSL2.
What
comes in to the building is a single pair of copper into the smartjack,
and
then you have a traditional DSX1 to plug in to. I don't think "real" T1s
(in
the physical sense) have existed for years.
Before DS1-over-HDSL2 the ones I had provisioned were DS1-over-HDSL (2
copper
pairs)... never had a real, genuine T1.
But again... you don't get to play with that side of it. You order a T1,
you
get a smartjack that has a T1 jack (DSX1) on it and what's on the other
side
is irrelevant.
