摘要： A method is described for the transmission of data among devices (D 1 ,D 2 ,... D i ,... D n ) connected to a communication channel (1) through sequences containing at least two symbols, one dominant ("0") and one recessive ("1 "). According to this transmission method, one (D TSG ) of the devices connected to the communication channel (1) has the function of time slot generator and it transmits on the communication channel (1) with a transmission frequency (f) a sequence of symbols, each defining a time slot in a sequence of time slots. The sequence of symbols comprises at least a series of recessive symbols (" 1 "). When one of the devices (D i ) has to transmit on the communication channel (1), it generates a sequence of symbols, synchronised with the sequence of time slots generated by the time slot generator device (D TSG ) and comprising at least one dominant symbol ("0").
