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 (3km) away at least. If you have any details of ATA boxes or other similar devices that I could use to do this, I‘d appreciate your input. It must be able to use a regular analog telephone handset on the far end.
I‘ve searched high and low and either I‘m not clever enough in using the right terms for this or it is rarely documented?
Any details much appreciated.
Thank you!

It's not expressed in distance. They will supply the current & voltage output and you need to apply ohm's law. That requires knowing the resistance of the cable which is dependent on length and gauge.
