asterisk users - Aug 2006 - can Digium FXS channels support been half mile to 1 mile length away from phone?

Hi all,

I need to setup 6 phones about 3/4 of a mile from the main box,   (can't 
do it with VoIP yet because of networking issues),  does anyone knows if 
the boards can resist such a length for FXS ports.  
Right now there is a Dialogic MSI160 working fine.

The actual length in a straight line is about half a mile,  it does have 
a single cable point to point, but can't be sure where the cable goes 
since it has to pass from one building to another,   so it might end up 
been quite a bit more distance.

If the answer is they can't handle such a distance does anyone knows  if 
there is an alternative,  (line booster or whatever similar )

thanks

Yep, there are analogue line boosters for your requirement.

 

Cheers,

Dean

With the exception of the ring generator on the digium card, the fxs 
port specs are basically the same as telephone company specs. Telco 
lines in rural areas often times exceed six miles. So, yes the digium 
card will handle your half mile just fine.

The ring generator on the card is much smaller then those used in the 
telco, and is likely limited to maybe two or three ringers at the 
distant location. Don't plan on attaching multiple phones to the fxs 
port at your remote location. (Same is basically true with the sangoma 
card.)
