But just to be safe, don’t work on phone wiring with wet hands or when standing in water. Rotate the strippers as needed to cut all the way around the sheathing, being careful not to cut into the insulated wires inside the cable. In this case, start by stripping only a small amount of the sheathing using wire strippers, then use the pull cord to cut back the sheathing two to three inches. Trim off the cut sheathing. Untwist the individual cable wires from one another.

In most cases, you need to strip only two of the wires, based on which phone line you are adding to:. Remove the cover from the front of the phone jack, exposing the mounting plate and mounting screw holes. Mount the plate to the wall, molding or other structure, using a drill-driver and small wood screws or drywall screws. Connect the stripped wires from the phone cable to the corresponding screw terminals on the jack, using the following color combinations; each jack terminal is identified by the color of the wire that is preattached to it:.

To make the wire connections, loosen each terminal screw with a screwdriver. Wrap the bare copper end of the wire around the screw with needlenose pliers. Tighten the screw to secure the wire. The wire insulation should stop just before the screw; none of the insulation should be under the screw. Reinstall the cover on to the jack’s mounting place.

Doing your own telephone wiring

I’m not familiar with the phone wiring conventions outside the U. In years gone past, it was the responsibility of the phone company not only to bring phone service to your house but to do the phone wiring within your house as well. This is no longer the case. When you order phone service to your house, the local phone company installs a network interface device , a sturdy grey plastic box usually mounted either in your basement or on an outside wall. You can do your inside wiring yourself, or you can pay the local phone company or a third party such as an electrician to do it for you. Doing residential phone wiring is easy, however, and the local phone company’s charges for this service are steep. Even if you have to buy wire and modular jacks, you’re going to come out way ahead if you do your own work. Installing extra lines can be a problem if you rent an apartment in a multi-unit building. The wiring between the network interface device and the apartment is not the phone company’s responsibility, so you’ll have to work out with your landlord who’s going to do the in-between wiring if you need additional lines. Your landlord may not want you to do the wiring for fear you don’t know what you’re doing; but the landlord may also object to picking up the tab if the phone company does the work. Whose responsibility it actually is probably depends on your lease. I once had a deadbeat landlord who I didn’t even bother approaching when I needed a second line installed.

To disconnect the line, find the telephone interface box which is usually mounted on an outside wall where the phone lines runs into your house. On older interface boxes without a test jack, unscrew the terminals and detach the wires, remembering which one went on which terminal. Remove the jack from the wall, noting which colored wires are hooked up to the terminals so you can match them to the new one. While only two wires are required for a phone to work, the cable usually contains four or more to provide for additional lines or in case one line should fail. These are color coded with red and green normally used for the first line, yellow and black for the second, and blue and white for the third.

The cable in your home may consist of only 2 pairs, 3 pairs or may be a 4 pair cable. Even though larger cables are made, it is unlikely that you would find them in your home. Color Code One is the old solid color code. Not used in new installations anymore. Each pair can be used as a phone line, so in this example you can use this cable for up to four phone lines. The primary color of the conductor is the first color listed, the second color is the tracer.

Wires, plugs, and the network interface The basics of the wiring is pretty easy to understand. Most telephone wires are one or more twisted pairs of copper wire.
