The telephone book: technology--schizophrenia--electric speech. [Avital Ronell; Richard Eckersley] -- "The book begins by calling close attention to the importance of the telephone in Nazi organization and propaganda, with special regard.

A telephone (derived from the Greek: τῆλε, tēle, "far" and φωνή, phōnē, "voice", together meaning "distant voice"), or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted.

In telecommunications, an electronic switching system (ESS) is a telephone switch that uses solid-state electronics, such as digital electronics) and computerized common control, to interconnect telephone circuits for the purpose of establishing telephone calls.

The generations of telephone switches before the advent of electronic switching in the s used purely electro-mechanical relay. Telegraph, any device or system that allows the transmission of information by coded signal over telegraphic systems have been used over the centuries, but the term is most often understood to refer to the electric telegraph, which was developed in the midth century and for more than years was the principal means of transmitting printed information by wire or radio wave.

The telegraph and telephone are both wire-based electrical systems, and Alexander Graham Bell's success with the telephone came as a direct result of his attempts to improve the telegraph. When he began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years.

Switches, PBX's, and Central Offices What is a telephone switch?Basically it is the device or system that connects one telephone line to another telephone line so that two or more people can carry on a conversation over their respective telephones or so that your computer's modem can connect to a remote modem such as a remote modem owned by an ISP (Internet Service Provider) which in turn.The purpose of this book is to give readers – in plain language – a fix on the current position of the Smart Grid and the components of modern telephony – cell phones, texting, cell towers, PDAs, etc.
