We have recently started installing 10baseT to replace our UB ethernet 
equipment.
The standard length for ethernet transmission over tp wire is 100 meters
(328 feet).
Using rg8 you can go 500 meters(1640 feet).
Using rg58 you can go 185 meters (573 feet).
This is according to the specs published.
We experienced some troubles using teflon plenum tp wire due to the 
change in capacitance in the wire, this reduced the maximum tp distance
to around 180 feet. It will not work on non tp phone(or rs232) wire.
It will work through 4 wire tp data circuits.

All in all, I am not impressed by the David Systems that we have purchased,
our Ungermannn Bass equipment was more flexible and has  better management
(once the bugs were worked out, we were a beta test site) software, but
David Systems promises more in the near future.
