Abstract

Abstract An apparatus for the transmission of information between a plurality of stations by means of a common transmission path for light call installations, light call speaking installations, speaking installations, surveying installations, remotely operative installations, person-investigating installations, remote indicators, remote control means, and the like, which comprise receivers, an impulse exciter and a counter chain including flip-flops. The receivers are operated only upon occurrence of a predetermined binary code in the receivers, the binary code being delivered by the impulse exciter by means of the counter chain which includes the flip-flops. A time period section, divided into two partial time periods, is coordinated to each of the receivers, and a corresponding receiver is selected by the binary code during the time period section within one of the part-time periods and information is transmitted to the receiver within the other of the partial time periods. Synchronously running counter chains and a conduit common to all stations are also provided and the counter chains are connectable with the impulse exciter by means of the conduit for setting the time period stations. The counter chains have at least as many flip-flops, as are required for the number of provided channels corresponding with the binary coding given by the flip-flops. Decoding circuits respond to the same counter position and are connected with the counter chains of the stations to be coordinated relative to each other. A gate is applied to the conduit. Time gaps, disposed between the impulses of the impulse exciter applied to the gate serve the transmission of the information. Upon expiration of at least one of the partial time periods for the synchronization of the entire installations a synchronous impulse is transmitted by filling out of the last of the impulse gaps, and at least one joint main station is provided for a plurality of extension stations connectable with the transmission path.
