Hold on while I run outside...

I have 1 copper pair assigned to DSL and 1 copper pair
assigned to POTS.
My FlowPoint 2200 Router says I have SDSL.

http://www.3com.com/technology/tech_net/white_papers/500624.htm
The Telecommunications Handbook, Volume 3
verifies that this uses one copper pair.

For POTS wiring see:

The Telecommunications Handbook, Volume 3

The main reason most people have to get a new phone line
is that USWest[spit] runs most residential phone lines thru
a SLC-96 multiplexer at the subdivision.
That unit is *not* compatible with any DSL and the second phone
line is ususally installed to bypass the SLC-96 unit.
