Abstract

The communication system has a plurality of subscribers connected through respective interface circuits to a ring feeder for the common transmission of digital source data and control data. The source data and control data are transmitted in a format which prescribes a pulsed sequence of individual bit groups of equal length. The bit groups are subdivided into component bit groups each forming a data channel. At least one date channel is provided for control data which are transmitted in data packets with a destination address. Furthermore, the interface circuit of each subscriber contains an address decoder. The communication system is simplified, and changes to the system are made easier in that at least one subscriber has a special address by means of which a received data packet is fed directly to an instruction decoder inside the interface circuit, which decodes to the bit base an instruction code contained in the data packet. The interface circuit, i.e., the subscriber reacts immediately to a corresponding instruction in the instruction code.
