[Asterisk-Users] Loop length supported by FXS module on Wildcat TDM400 card

[Elliot Eichen]

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
