asterisk users - May 2004 - Loop length supported by FXS module on Wildcat TDM400 card

Does anyone know (appoximately) the max loop length that the FXS module on a
Wildcat TDM400 card will drive an analog phone(over standard - say cat3 or
26 gage twisted-pair wire).  It's clearly not going to be 18kft, but perhaps
4000 feet?
 
Thanks

I'd be wary of 4kft even if it could do it. Thats a long way for
something to short/introduce power and fry your complete computer.  It
would be pretty easy to put a cheap pc local and run a few feet of
cable. This is especially true if you run more than one line. 

Considering the last time I priced cable, a 4000ft run would cost as
much as the card or more, just put a machine local to that extension.
