If you have line of sight and are prepared to DIY, consider an optical through the
air solution. (assuming you can get some sort of computer installed at the
property boundary).  The 'ronja' project offers plans for a 20Mbit/s full
duplex Ethernet link with a proven range of 800m.  A 200Mbit/s version is
in the pipeline.

There are also numerous projects out there to do analog modulation if you
just want to repeat the signals on the phone line.  For phone line frequencies
(4kHz), you should be able to get away with a cheap LED/phototransistor combination.

If necessary, use a cheap 'winmodem' as a legal form of line termination
unit, to get Telsta's signals into a domain where you can do what you want
with them.
