Hello.
I am looking for details of the maximum allowed/usable/effective wire/cable
length of the connection from a FXS port of Digium analog cards to the
analog telephone handset.
To clarify my intention, I need to have an analog telephone connection to my
asterisk box that is 3000 meters (

The best a native cat5 can run is 100 meters. Unless you like paying your

I was doing that too. I asked this same question a few years ago and
the answer was 100-200 meters. This is just

That is a pretty long run.
The type of analog phone can be an issue. How LITTLE loop current will
it operate on? Most need more than 20 Ma to signal properly, and the
voltage output of the ATA needs to be known
Type of signaling? DTMF? pulse?
Interconnection cable wire size and capacitance will

Excellent analysis of the real world. Start with this, and work out the
issues, or go to VOIP.

There are a lot of factors that impact this. First, CAT 5, while usable is
overkill. Cat 3 (otherwise known as I/O wire) works equally well for voice
grade lines. That being said, for that long a run, a heavier gauge wire
would be better. I believe telcos use 18 - 22 guage (Cat 5 and Cat 3 a

I could be wrong but I don't think the cat5 limit of 100 meters applies to
any analog signaling over that copper. I believe it only applies to Ethernet
signaling.

For long distances, a wireless point-to-point might be more economical
than trenching.
