ABSTRACT:
The method deals with the transmission of data frames that comprise address information, useful data, and a check sequence, through a transmission channel. The data sources evaluate a data collision signal whose value corresponds to the logic AND combination of all the output signals of all the data sources using the transmission channel. Each data source transmits, between two data frames, an idle bit sequence, which is given by a sequence of logic one values in the event of non-identity between the output signal of the data source and the data collision signal, and is given by a FLAG signal after the complete transmission of a data frame or after the abortion of the transmission of a data frame or if the data collision signal contained in direct succession a larger number of logic one values than the transmission abort signal.
