We order these all of the time ( as a CLEC) for EoC connections or DSL on our
equipment. The correct terminology is usually 2-wire or 4-wire copper loops.
There will be specific NC/NCI codes depending on the iLEC region you are in and
LEC you are working with.
Within these loops, you will generally see at least the following "types" of
circuits, normally these are really just different levels of qualifications the
LEC is required to meet on the copper they provide (in terms of noise,
attenuation, load coils, and # feet of bridge tap):
HDSL (best)
ADSL
UCL (Unbundled copper loop - worst)
Now the main issue is that these circuits are normally provisioned between a CO
and an end-user location. I don't know if you'd be able to get them directly
between two sites that are not ATT facilities without going back to the CO
first (greatly increasing total loop length and probably decreasing max DSL
speeds).
The other thing to know is that in "busy" CO's, some of these line types
(especially the higher quality loops) may be "blacklisted" meaning you either
can't order them at all, or you can order them a different way at a much higher
rate.
The last issue I can think of is that you may not be able to get these at all
from ATT's retail or business side of the house. If that is the case, find a
local CLEC and see if they will help you out.

Subject: AT&T Dry Pairs?
Has anyone had any luck lately getting dry pairs from AT&T? I'm in the Chicago
area attempting to get a dry pair between two buildings (100ft
apart) for some equipment, but when speaking to several folks at AT&T the
response I get is "You want AT&T service without the service? That's not
logical!". Had no problems 3-4 years ago getting these sorts of "circuits", but
it appears it's gone the way of the dodo now. Any emails off-list are
appreciated.
