Phone Extension Length FROM cable router

[barlaventoexpert]

Here in Portugal I have a client with a branded ZON cable router with a RJ11 phone socket.

When you plug a phone directly to the sockect or via a short RJ11 extension cable the line works.

However, I would like to run a phone extension cable of about 35m to another part of the building.

What is the maximum length for a such phone cable from the RJ11 socket on the router to a phone?

Will the extension length be limited by the router´s power output?

I don't remember how far a phone can go, they run phone lines from the phone company to your house so it is a lot. You will have no issues at all with 35m. The phone jack is designed to provide power to the phone without affecting the router.
