A LATA or local access transport arrangement line, a bare piece of copper
is measured in length in distance from one end to the co and then
distance from the other end to the CO.  It is then charged by the sum
of those two distances.  It is only really useful within the same CO.

I had one for several years, and you have to be very careful.  The
speed drops off greatly as the distance goes up.  At one mile you
can do 19200, at our length, 3-4 miles it was more line 9600 only.

The line is called a 9004 is our area, is a special beasty, and not
many of the people know about them.  It was not cheap, ran about
90/month when we dropped it over a year ago, up from the 24/month
when we started it three years before that.

Major complaint, until they invented a way to put sealing current
on it (most 9004's are really dry, no sealing current even), it would
fail once a month, or when it rained heavly.  Also, without battery,
every so often someone would swipe the pair for some other use. (Even
though the connectors had rubber covers that were marked DATA.  After
the engineering change, all went well.  We dropped due to change in
office locations.
