How does the phone work?

The basic electromechanical functions that cause the phone to work are relatively simple and straightforward. This explanation describes the processes that cause the phone line to function. The processes that cause mobile phones to work and allow voice phones to operate over the Internet (VOIP) are a little more complicated, require radio waves and internet protocol (IP). However, the basic principles for the functioning of any phone are the same.

You want to create a fixed line, two copper wires must transmit two things: signals and voice. Two wires, usually covered with green and red, are the heart of the process that causes the phone to work. While the phone rests on the hook or in the cradle, the capacitor inside the phone's cradle limits the amount of electric current flowing to ring, in fact the chip in a small speaker. The capacitor prevents short -circuit in wires and the local phone replacement device acknowledges that the phone is suspended.

for the correct phone operations, the sound must be mediated along the same wires that activate the ringtone. The handset of all phones contains a microphone that allows you to transfer sound pulses to electrical pulses. The second integral part of the headphone, the receiver, converts the audibly modulated electric current back to the sound waves and the voice is heard. Therefore, the transmission and intake of voice depends on the sound waves and on the electric pulsation.

When the phone is in the cradle, only the ringtone, the chip is electrically connected. When the phone receives an incoming call, the local phone replacement sends a high alternating current (AC) to the cradle switch. This overvoltage suppresses the capacitor and the integrated circuits of the cradle (IC) cause the phone to ring. For US phones, this increase is usually in the range of 20 Hertz (Hz). The phone receives the calls selected using multifrequency pulses (DTMF) dialing, buttons on the calling side keyboard. When selecting transmission andReceiving the headphones The switch in the cradle transmits the electric surge from the alternating current to the direct current (DC), allowing the voice transmission over two wires. Two cradle switches then energize the shorts of resistance through their respective wires, create at the end of the broadcast tone and activate the ringing at the receiving end.

The alephone primary wires run from phones to phones and in the entrance boxes in the house or building. From there, telephone cables strung on the ubiquitous telephone poles along the street pass calls for local exchange. From local exchange, fibrous optical line, radio transmission and for remote calls, satellite transmissions transmit a call to a destination where it ends back to two copper wires.

Radio waves are used to make a mobile phone correctly. Internet protocols (IP), network digitization and packet switching are used to ensure the operation of the VoIP phone.
