Abstract

A telephone system comprising remotely located stations each of which contains in a single unit the equipment for simultaneous communication on two different channels, signaling equipment for calling an abandonment of motor on either of the two channels, and a pair of receivers selectively assigned one to each channel, in which a subscriber in any channel is called by a call signal appearing at the output of one of said receivers, characterized by detector equipment and call signal transducer in each station comprising a single call detector means capable of differentiating between the call signals from said receivers, a single call signal transducer and switching means under the control of said detector means to switch said transducer to the channel associated with the receiver in which said signal appears call.
