Abstract: A station (ST) of a multi-station ring communications network (RN), wherein data are transmitted in a predetermined direction includes a frame receiving device (DRX) for frames received from the ring, and a frame transmission device (DTX) for transmission of frames to the ring. The station (ST) further includes a FIFO repetition memory (ERPT), disposed in series between the reception and transmission devices, wherein the reception device (DRX) decides whether the frames coming from the ring should be either destroyed or repeated and subsequently sent to the repetition memory (ERPT). The transmission device (DTX) transmits the frames contained in the repetition memory or the frames proper to the station, by deciding whether the station has the right to transmit as a function of the contents of the repetition memory.
