TELEPHONY

Telephony is the transmitting of sounds over a considerable distance by means of electric current, using wires. Telephony as a means of communication is widely used in modern life all over the world. By means of a telephone apparatus people can communicate with each other at distances of thousands of kilometers.

The transmission of sounds over a distance is known to be transmission of oscillations. In order to carry on communication, the frequency of the transmitted oscillations should be constant during the whole period of communication. The circuit, which is closed when the line is connected, consists of a transmitter and a receiver connected by an electric conductor.

A telephone transmitter is usually a carbon microphone. Its main parts are microphone housing, carbon chamber, carbon diaphragm, carbon granules, insulating spacer, and conductor.

By means of the carbon microphone, variable electrical impulses are caused to flow through the circuit. These variable impulses depend on the nature of the sounds supplied into the microphone. During the process of communication current passes through the diaphragm, carbon chamber, and carbon granules. The sound pressure on the diaphragm varies the pressure on the granules of carbon. These granules either make more contacts and decrease the resistance of the granules, or make fewer contacts and increase the resistance.

Sound waves produce oscillations of the same frequency as those of the sound body. As a result, both the transmitter resistance and the current in the circuit change.

The varying current passes through the receiver connected to the network. The receiver of a telephone apparatus consists of electromagnetic coils, a steel magnet, and a diaphragm. The diaphragm, magnet, and the coils are housed in a plastic cap. During the process of communication, the cap of the receiver is pressed to the ear. A variable current passing through the magnets coils changes the position of the diaphragm; it makes it vibrate. The frequency of these oscillations is the same as that of the transmitter. Therefore the receiver reproduces the same sounds as those that are spoken into the microphone.

TELEPHONE SET PROTECTION

Transmitting lines that serve telephone seta may have contacts with power lines or with lightning. Therefore telephone sets and their lines need protection. Protector units connected to the transmitting lines serve as protection devices.

Usually a protector unit consists of carbon protector blocks connected between each wire of the line and the ground. Fuses are also the widely used elements of the protector blocks; they protect protector against power contact currents.

It should be noted that fuse is an important part of protector blocks; without it power contact currents may overheat the protector or its ground conductor. But sometimes fuses are not used. No fuse is used in case the building is served by insulating wires that are connected to metal-sheathed cables on the line pole.
