I've been given a large spool of 22 gauge shield communication wire. Its got 4 individually shielded copper wires, all within an outer jacket. I know most residential phone lines are 4 wires, as is this, so I'm thinking its just a high quality phone line?

I don't see any reason why this wouldn't work for running phone lines in my house, but can anyone confirm it should be fine?

I'm going to be attempting to runsome coax in my house, so might as well replace the phone lines while I'm at it since I've only got 1 total phone jack on my 2nd and 3rd floors. I saw attempting since its a 150 year old house mostly stone house, so I may run into some roadblocks.

thanks
Bruce
