Abstract
A cordless telephone system in which a communications path is established and maintained between a base and a remote unit with the transmission of a binary coded pulse train. Maintenance of the communications path in this manner does not require multiple carrier signals and avoids interference between adjacent remote units. A microphone switch is also provided that prevents accidental turn-on of the remote unit, thus preventing accidental battery depletion.
