A data transmission system comprising a transmit unit (2) having a buffer (22) for generating a delayed version of the transmitted data signal and the receive unit (4) comprising a buffer (47) for generating a delayed version of the received data signal error detection means for detecting errors in the received data signal and means for signalling the transmit unit (2) to transmit the delayed version of the transmitted data signal. The transmit unit (2) includes means for multiplexing data with control data and sending the multiplexed signals via at least two transmission lines.
Un système de transmission de données comprend un module d'émission (2), doté d'un tampon (22) pour produire une version retardée d'un signal de données émis, ainsi qu'un module de réception (4), doté d'un tampon (47) pour produire une version retardée d'un signal de données reçu, un dispositif chargé de détecter des erreurs dans le signal reçu, et un dispositif qui commande au module d'émission (2) d'émettre la version retardée du signal de données émis. Le module d'émission (2) comporte un dispositif de multiplexage de ces données avec des données de commande et d'envoi des signaux multiplexés par deux lignes de transmission au moins.
