How The Telephone Works When a person talks into the telephone, the sound waves strike the diaphragm and make it vibrate. the diaphragm vibrates at various speeds, depending on the variations in air pressure caused by the varying tones of the speaker's voice. Learn the basics of telephone systems, including key terminology, how they work, touch tone technology, and borscht functions. understand the evolution from traditional pots to modern mobile communication. It connects telephones using a mix of wires, cables, and switches to route calls from one phone to another, whether they are next door or on the other side of the world. telephone network uses circuit switching. originally, the entire network was referred to as a plain old telephone system (pots). When we telephone someone, the mic in the first part of the telephone converts our voice into electrical waves. when these waves reach the other person's receiver, they are converted into sound again.

When we telephone someone, the mic in the first part of the telephone converts our voice into electrical waves. when these waves reach the other person's receiver, they are converted into sound again. To make a call, a telephone subscriber begins by taking the telephone “off hook”—in the process, signaling the local central office that service is requested. the central office, which has been monitoring the telephone line continuously (a process known as attending), responds with a dial tone. The first working telephones using this principle used a liquid to create the variable resistance. you would speak downward into a tube; this would cause a membrane (a small disk made of metal) to move and vibrate according to the intensity of the sounds in your voice. The sound waves that you create by speaking into a telephone's transmitter are turned into electrical signals that are carried along telephone wires and delivered into the telephone receiver of the person that you have telephoned. The two wires, usually coated green and red, are the heart of the process that makes the phone work. while the telephone rests on the hook or in its cradle, a capacitor inside the phone cradle limits the amount of electrical current flowing to the ringer, actually a chip within a small speaker.
