What is the telephone's purpose?

To enable two remotely located users to communicate by voice between each other Telephone conversations started as analog signals over wires. Later, many of the signals were transmitted long distance by microwaves through the air. For several years now, the user's voice travels as digital signal over most of the distance.

The normal analog telephone is connected to the CO (central office) through copper wires. This portion of the conversation is in analog form. The analog voice is converted to digital form in the CO and it travels as high speed data to the destination CO, where it is converted back to an analog form to be sent to the end user.

More and more analog telephones are being replaced by digital telephones. The digital telephone converts the users analog voice signal from the microphone to a digital signal inside the telephone itself. The digital data then travels to the destination user with very little chance for noise or distortion to affect its quality.

The signal is often so good that you often don't know if the connection has been lost or not without the usual hiss and static that we are accustomed to. The digital signals on the public phone system travel by microwave over land, from ground stations to satellites, or as light waves over optical fiber or through the air. Light communications by air are only for short distances Companies like Vonage, Skype, Covad, and Speakeasy provide what is called VoIP or Voice over Internet Protocol.

With VoIP, you can make a call using several methods One is by using your computer to convert your analog voice to digital and then transmitting the digital conversation over your digital Internet connection Another VoIP method is by connecting your regular analog telephone through the service provider's 'black box'. The box is a device that has its own small computer inside which manages the telephone conversation, communicating with the Internet to find the service provider's server. The voice signal is converted to digital form.

The controller then sends the conversation through the VoIP server to the destination user. If the destination user has a VoIP telephone connection they receive the conversation in digital form. If the distination user has a regular analog connection, the digital conversation data must first be converted back into analog form.

This can be done in the CO through special equipment designed for this purpose Yet, another VoIP method is by using digital telephones on a digital data network. The digital phones can communicate through a VoIP PBX (private branch exchange)to the Internet or directly to the service provider out on the Internet Answer After 9/11, the purpose is to give the government agencies a way to monitor your activities without bothering you by ringing your doorbell and asking yes!
