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

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

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

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.

You may be able to boost the battery voltage with a simple dc adapter in

floating with respect to ground and wire it in. Don't be afraid of
hurting the phone, you won't.
But it is possible to hurt the ATA if it
