METHOD AND DEVICE FOR AUTOMATICALLY TIMING STATIONS IN A TIME MULTIPLEX FOR OPTICAL BUS AND DATA TRANSMISSION AND PROCESSING SYSTEM COMPRISING SUCH A DEVICE

摘要

P IN A MULTIPLEXED TRANSMISSION SYSTEM AND DATA PROCESSING BETWEEN A NUMBER OF N STATIONS DISTRIBUTED ALONG A UNIDIRECTIONAL BUS BUS 16 AND CONNECTED TO IT THROUGH N 20A COUPLERS 20A PLACED ON THE PATH OF THIS BUS, AUTOMATIC TIME CALCULATION METHOD OF THESE STATIONS CHARACTERIZED IN THAT IT INCLUDES AN EMISSION PHASE, DURING WHICH A BINDING MEMBER 17 ALSO PLACED ON THE BUS TRAIL 16 EMET A FRAME TITLE OF EMISSION AND COMPOSED OF A SYNCHRONIZATION WORD AND ONE OR MORE INITIALLY EMPTY FRAMES OF DATA AND CORRESPONDING TO THE TIME POSITION CARRIED OUT BY EACH OF THE STATIONS, A RECEPTION PHASE WHERE THE DEMODULATION OF THE TRANSMISSION FRAME IS PERFORMED BY THE CLOCK MASTER OF THE BONDING BODY 17 THEN THE REPLACEMENT, IN THE FORM OF A FRAME RECEIVED, OF THIS FRAME TO THE COUPLER OF EACH STATION SUCCESSIVELY, AND, AFTER THE RECEPTION PHASE, NEW PHASES OF TRANSMITTING AND RECEIVING, UNTIL THE INSERTION OF DATA ON THE BUS BY EACH STATION DURING A TRANSMISSION PHASE CAN BE CARRIED OUT WITH THE PRECISION REQUIRED. / P P MINI-COMPUTERS WITH LOW GEOGRAPHICAL DISPERSION. / P
