An RJ-11 connector is the standard modular plug on the end of today's telephone lines. The plug can have two, four or six wires. The RJ-11 jack has six terminals. Most homes use four wires.
A single line telephone would have one pair of wires attached to the plug and a two-line telephone would have two pairs. The third pair can be for a third line, or an accessory circuit for special applications.
The center pair of pins is for line one. The two pins on each side of the center pins are for line two and the remaining outside pair is for the third line or an accessory. Telephones come with the plug attached and ready to insert into the jack.
Things You'll Need
- RJ-11 wall jack
- Wire cutters
- Utility knife
Cut off 2 inches of the outer jacket on the telephone cable. Use a utility knife and carefully cut around the outside of the cable. If you nick any wires, cut the cable and try again.
Spread the wires apart with your fingers and pull the ends so the wires are straight and flat. Do not strip the ends of the wires. Insert the blue wire into slot No. 3 and the white/blue wire into No. 4. Use the plastic tool provided to push the wires into the slots on the jack. The jack will cut the insulation and allow the wire to make contact with the pin.
Insert the orange wire into slot No. 5 and the white/orange wire into slot No. 2. Push the wires in place with the tool.
Insert the green wire into pin No. 6 and the white/green wire into pin No. 1. Use the tool again to finish the wiring. Cover the exposed connections with the plastic caps that came with the jack.
Attach the jack to the wall box with the supplied screws.
Tips & Warnings
- Make sure the ends of the wires do not touch inside the jack.
- Leave excess cable in the box for future projects.
- The telephone wire may have four pairs of wires. For this project, the brown and the white/brown wires are not used.
