Abstract

See full text

The invention is a telephone system capable of operating on a single internal telephone line as commonly found in the home or small businesses, which is economically implemented within an integrated circuit chip to provide a one chip telephone and which provides most of the components necessary for a full-featured, reliable and easy to install office communication system. The multiband audio network (MAN) transfers four audio bands and a digital data band over a single twisted pair of wire. A 6,000 bits per second full duplex digital data channel is also provided on the same twisted pair. Each station unit includes all the control and interface support necessary to perform conventional telephone functions. These functions include a combination of keyboard and display support circuitry such as strobe and debounce circuitry, LED buffers, piezo ring drivers, control registers and communication hardware. Everything needed to provide a programmably customized communication and telephone network is available using only one basic chip design in the system as described above. Not only are standard telephone communications possible on a single twisted pair, but a network of telephone receivers, computers, modems, telefax devices, answering machines and any other type of information handling or communication device now known or later devised for use on a telephone line can be networked and accommodated within the system.
