Re: Extending network over a dry pair

Six miles is probably pushing it, but Proscend make some interesting Long-
Range Ethernet SFP transciever which are VDSL based. They're
horrendously documented and they draw *way* more power than the SFP
specification allows.
They also make a version which is design to terminate VDSL broadband
circuits - A couple of those found their way to my desk recently and it
turns out that despite the horrendous documentation and sightly scary
heat output (they come with a little paper note in the box which says
something along the lines of "WARNING! MODULE GETS HOT - DO NOT TOUCH
DURING OPERATION."), they do generally Just Work!

A quick question for you guys; 

If you had a single dry pair (pair of copper wires originally for
phones) to a remote site that was around 6 miles away, what would you
use? We currently are just extending a T1 line to this site, but
1.5Mbps isn't cutting it anymore. Unfortunately it's a research site
on a federally protected wildlife preserve so we can't run any new
infrastructure (fiber etc) and it isn't in a geographical place where
point to point wireless is practical. We were thinking there is some
sort of network extender that uses some form of DSL for higher
bandwidth capacity.> 
Any suggestions?
