Home Telephone System

Although the telephone company owns the wires that bring telephone service to the house, repair and new installation can take place in any part of the telephone system that extends past the company's demarcation jack. The demarcation jack is usually located in a basement or utility area, although it may also be mounted on a baseboard in a home's living quarters.

Because the voltage running through telephone wires is very low, there is little danger of shock when working on the wiring. Still, it is best not to work in wet conditions when repairing any wiring. Also, do not work on a phone system if you wear a cardiac pacemaker, because the mild electrical currents in phone lines can interfere with the device.

Common telephone repairs include replacing a loose or broken modular connection, installing a modular jack in place of an outdated jack, and installing a junction box that allows additional phone jacks to be run anywhere in the house.

A phone can be plugged directly into the demarcation jack to find out if a problem lies in the house wiring or in the phone company's wires and equipment. If there is no dial tone at the demarcation jack, the problem lies outside the home and should be fixed by the phone company. If there is a dial tone, however, this means that any problem lies inside the house.

Note: As the needs for Internet service and network data links in the home become increasingly important, larger and stronger telecommunication cables are needed in place of standard two-way telephone lines. Pages 272 to 293 contain information on telecommunication cable and home network systems available for home installation that allow faster and more reliable pathways for data and telephone transference.

Telecommunication System Wiring

Two methods are used to wire phone systems. Relatively new systems are wired using the home run method (shown above), in which a wire distribution hub, or junction box, feeds individual lines to various phone jacks in the house. A junction box allows new jacks to easily be added by running new wires from the box to the new location. If one line becomes dam aged. the other jacks will still operate. Older systems use a continuous loop method. With this method, various jacks are installed along a single loop of wire running throughout the house. A continuous loop is easier to install but less reliable since a single problem in the wire can render all the jacks inoperable.
