Abstract

Duplex transmission network by rasters of known format of digital coded messages between a master station and one of the slave stations, on watch on a same feeder. Each message transmitted to one station includes a acknowledgment signal of the last message received from that station. The device is provided to allow a retransmission of the two last messages when one message received is erroneous. To this effect, it comprises a detector (5) for the acknowledgment signal, a detector (4) for the erroneous messages received, a switch (7), a acknowledgment signal coder (6), a transmission control device (9) and two memories (10, 11). Application to data transmission and telephony.
