Re: Wiring Two Lines on One Jack

I would like to wire one jack for two lines. Here is the setup of the

I think you will find that your house was not wired "home run" to each jack. In other words, one pair goes back to the demarc block and the two other pairs go to other jacks in the house.

The colors don't really matter other than for keeping track of what's going on. You need to start at the demarc and select an unused pair for the second line. When you get to the phone jack, you need to know if your phone is a single line or dual line phone. If its a dual line phone, then Pat's advice is correct. Wire line 1 to the inner pair of the jack (red/green on some jacks) and wire line 2 to the outer pair (yellow/black).

If the phone is a single line phone and you want it to access Line 2, you will need to wire Line 2 to the inner pair.
