Yes, there was a discussion here before. If the cables between the sites 
are less than 3000ft (1000 meters) then you will have best luck with VDSL 
of some kind. A pair of VDSL modems which will give you something like 10 
meg, will set you back USD$200-400 or so. Zyxel 841 is one for instance.

If you have more copper pairs you can use VDSL equipment at both ends and 
bundle them, there is equipment that'll do 24 pairs which should give you 
quite a lot of bw. If the distance is longer you can bond more pairs with 
g.SHDSL to get more bw.

There is a g.shdsl VIC for 2600 that'll do g.shdsl as well, it'll do 
four-wire too, to double your available bw.
