Telephone connections enable users to communicate with other telephone users around the neighbourhood and around the world. Though the telephone network and connection may seem like a complex and highly technical system to those unfamiliar with its operation, you can wire your own telephone connection using only basic tools and a little knowledge.
- Skill level:
Things you need
- Phillips screwdriver
- Flat head screwdriver
- Wire strippers
- Wire cutters
- Length of standard telephone wire
- Telephone jack
Run a length of telephone wire from the intended jack location to the network interface device (NID). Starting from the location where you intend to install your jack, run a length of standard four-wire telephone line to the grey or beige telephone network interface device (NID) outside your home or office. Note that you may need to drill through floors or walls to run this line.
Strip away the insulation from each end of the telephone wire. Use the wire strippers to strip away about 1 to 2 inches of the grey or beige outer insulation from each end of the telephone wire. The four inner colour-coded wires should become exposed when you remove the outer insulation.
Strip away the insulation from the appropriate inner wires. If you intend to wire only one line in your telephone connection, use the wire strippers to remove about one-quarter of an inch of insulation from the red and green inner wires. If you intend to wire two lines in your telephone connection, strip away one quarter of an inch of insulation from all four wires bundled inside the outer insulation.
Open the jack. The jack you purchased should come from the factory in a closed position. If a screw holds the jack together, use a screwdriver to remove the screw and pull away the outer case of the jack. If the jack does not feature a screw, it may be held together by small plastic clips; if no screw secures the jack together, grasp the plastic casing and the plastic backing then firmly pull them apart.
Connect the appropriate wires. Once you open the jack, you will notice four wire terminals featuring the same colour codes as your telephone wire. If screws hold the terminals closed, use a screwdriver to loosen the screws. Do not remove the screws. Wrap the exposed portion of each wire to its colour coded terminal, wrap the exposed portion around the screw and re-tighten the screw to secure the wire in place. Repeat this process for the red and green wires if you are only wiring one line, or for all four wires if you are wiring two lines.
Reassemble the jack. With all wires secured in the appropriate terminals, replace the jack cover and firmly squeeze it into place. If the jack does not use a screw, the jack cover should make a snap sound as it connects to the base. If a screw holds the jack together, insert and tighten the screw after reassembling the jack. Use care to ensure the telephone wire exiting the jack goes through the provided hole in one side of the jack.
Mount the jack to the wall. Your jack should have come from the manufacturer with either mounting screws or double-sided tape. If the jack attaches to the wall using screws, place the jack in your desired location, insert one screw through the jack's screw eye and use a screwdriver to affix the screw to the wall. If the jack came with double-sided tape, remove the backing from the tape, adhere one side to the jack, place the jack in your desired location then press it firmly to the wall.
Connect the telephone line to the NID. Outside your home or office, the telephone company has attached a grey or beige box that connects your telephone jacks to the company's network. Open this box by removing any apparent screws and firmly pulling the cover back. Inside, you will find the same colour codes featured in the jack. Strip away the appropriate insulation as you did when wiring the inside jack, then use a screwdriver to loosen (but not remove) the screws securing the red and green terminals. Wrap the exposed portion of each wire to its colour coded terminal, wrap the exposed portion around the screw, and re-tighten the screw to secure the wire in place. Repeat this process for the yellow and black wires if necessary. Close the NID and replace any removed screws.
Tips and warnings
- Most telephone companies allow customers to access the NID, though some restrict access. If your NID contains instructions to call your local telephone company before opening, stop and dial 6-1-1 for assistance.
- If your telephone connection does not work or if you hear static after performing these steps, check for loose connections inside the jack and NID.
- Telephone lines carry low voltage electricity at all times; though the voltage and amperage on a telephone line are very low, always use caution when working with electricity of any kind.
