I believe your pushing the limits as to ethernet over Cat5.
I can suggest you use the very best cable (shielded of course) you can get,
and be meticulous in your connector installations and you might get away
with it. Avoid other wiring if possible (fat chance huh?) and anything

putting a shield on cat5 or 6 cable doesn't significantly increase the
noise rejection vs utp cat 5 at 100mb/s, you're shielding already
balanced cable pairs.
moreover they're signifcantly harder to install since they need to be
properly grounded and shielded at both ends.

you need to put a fluke lanmeter or similar device (with tdr) to validate

You could use fiber and a fiber conversion box.
Or you could use a switch or repeater half way.

Steve,
What type medium are you using? If it is normal Cat5/6 then the
limitation is 100 meters for total distance and as you approach that
limit the signal degrades. That said, 100baseFX can run for 400 meters
due to the fact that it is fiber, both are part of the fast Ethernet
specific
100 meters is, in fact, the distance limitation for Fast Ethernet, but you
can usually exceed that if the link is full duplex. Note that I'm not
recommending that you do so, just stating that it is possible.
If your run length is more than 100 meters, and you're running half duplex,
then I would

The helpful guy at NOTA indicated that ATT does have significant

only one that didn't have direct presence was T-Data, but was accessible
