Telephone , an instrument designed for the simultaneous transmission and reception of the human voice. The telephone is inexpensive, is simple to operate, and offers its users an immediate, personal type of communication that cannot be obtained through any other medium. As a result, it has become the most widely used telecommunications device in the world.

Billions of telephones are in use around the world. This article describes the functional components of the modern telephone and traces the historical development of the telephone instrument. In addition it describes the development of what is known as the public switched telephone network PSTN. For discussion of broader technologies, see the articles telecommunications system and telecommunications media.

For technologies related to the telephone, see the articles mobile telephone , videophone , fax and modem. Within 20 years of the Bell patent , the telephone instrument, as modified by Thomas Watson , Emil Berliner , Thomas Edison , and others, acquired a functional design that has not changed fundamentally in more than a century.

Since the invention of the transistor in , metal wiring and other heavy hardware have been replaced by lightweight and compact microcircuitry.

Such advances supplement, but do not replace, the basic telephone design. As it has since its early years, the telephone instrument is made up of the following functional components: a power source, a switch hook, a dialer, a ringer, a transmitter, a receiver , and an anti-sidetone circuit. These components are described in turn below.

The first sources were batteries located in the telephone instruments themselves, but since the s current has been generated at the local switching office. The current is supplied through a two-wire circuit called the local loop. The standard voltage is 48 volts. Cordless telephones represent a return to individual power sources in that their low-wattage radio transmitters are powered by a small e.

When the telephone is not in use, the battery is recharged through contacts with the base unit. The base unit is powered by a transformer connection to a standard electric outlet.

The switch hook connects the telephone instrument to the direct current supplied through the local loop. In early telephones the receiver was hung on a hook that operated the switch by opening and closing a metal contact. This system is still common, though the hook has been replaced by a cradle to hold the combined handset, enclosing both receiver and transmitter.

In some modern electronic instruments, the mechanical operation of metal contacts has been replaced by a system of transistor relays. Article Media. Info Print Print. Table Of Contents.

Phone spoofing is when someone disguises the number they are calling or texting from by changing their caller ID. Some businesses do this legally and for legitimate reasons. They hijack or imitate phone numbers, either to imitate a person, business or department to get money or information. Or to appear like a local or legitimate number to increase their chances of getting through to their victim.
