ABSTRACT:
Several communication stations are connected to the electrical distribution circuit and emit on the latter information by injection of carrier currents, in the form of frames comprising a predetermined number of bits emitted sequentially. In the course of the emission of each bit, a bit is received as echo of the emitted bit and the echo bit is compared with the emitted bit. In the event of detection of a collision, the stations involved in said collision are placed in a state of listening for a succession of items of information emitted on the electrical distribution circuit respectively by the other communication stations according to a predetermined order of priority.
