How to Install Telephone Equipment

    • 1). Mark locations of where telephone jacks will be installed. Use an electronic stud finder to make sure that you're not drilling into or cutting into a wall stud. For ease of installation, you will be wiring the telephone jacks using a Buss Topology, where the telephone jacks are wired in parallel with each telephone jack acting as a feed through device carrying the service to the next jack. If you are installing a cordless telephone system, the telephone jacks should be located adjacent to electrical outlets.

    • 2). Cut the openings in the wall finish for the device boxes using one of the device boxes as a guide in outlining the cutouts. The objective is to make the cutout conform as close as possible to the dimensions of the box. Installing boxes in the wall isn't mandatory, but using them makes for a neater, more professional appearance. For neatness in appearance make these cutouts so they will be even with the electrical outlets in the room. As a rule the top of these boxes are 12 inches above the finished floor line, but check the other outlets in the room in case there is a variation.

    • 3). Drill a 3/8-inch hole in each corner of the cutout and then use the portable jigsaw to remove the cutout.

    • 4). Drill down through the wall's sill plate into the basement or crawlspace using a 1/2-inch spade bit. Use the drill extension if needed.

    • 5). Open the customer's access side of the NID box. The NID is usually located on the outside of your home in close proximity to the electric power meter. Once inside the NID box, you will see four color-coded screw terminals. The two that you are interested in if you're installing a single-line telephone system are the red and green terminals; the yellow and black terminals would be used for the second line if you had two lines coming into your home. There's also a short cable with an RJ-11 plug that couples the Telcom side of the NID to your side. Unplug this coupler until you finish your wiring.

    • 6). Route the telephone station wire from the NID to the first telephone jack. Route another section of wire from the first jack to the second one. Repeat until you have wire running to all the jacks. Use a fish tape to pull the wires up through the sill plate and into the room.

    • 7). Insert the cables into the device boxes, place the device boxes into the wall cutouts and secure them in place by tightening the screws drawing the mounting wings tightly against the inside of the wall surface.

    • 8). Remove 6 inches of the outer jacket and remove 1/2-inch of insulation from each red and green wire. Connect the red and green wires to the red and green wires (terminal screws) on each of the jacks. Secure the jacks in the device boxes. The jacks are actually part of the box cover plates.

    • 9). Connect the red and green wires at the NID, reconnect the patch cord, and close up the box.
