Telephone Jack - How to Wire It

A surface mount telephone jack can be wired in ten minutes by connecting all similar color wires together.

1. Open the Network Interface Device (NID), or small grey box mounted on a wall just outside your home. 
2. Unplug the short telephone cable from its jack inside the NID. Unplugging the jack will disconnect the telephone company wires from your household wires and make it safe for you to touch the wires.
3. Remove the telephone jack cover.
4. Loosen the terminal screws on the jack counterclockwise, then connect each wire coming from the telephone cable onto each terminal by wrapping the wire clockwise onto a terminal having same color.
5. Tighten each screw and replace the jack cover.

Tips:

       A single line (Line 1) telephone uses a green and a red wire.

       The second line (Line 2) uses a black and a yellow wire.

Things Needed:

• Screwdriver
