Abstract
This closed loop multiplex communication system uses a timing unit to establish a general multiplex format consisting of 1024 frames in a multiframe. Each subscriber station transmits one message bit per frame (i.e. 1024 message bits per multiframe), but transmits only 32 signalling bits per multiframe (i.e. the eight-bit non-message blocks in four corresponding frames).
