Abstract
A method for establishing a duplex connection for data transmission between transmission units in a communications system, wherein the transmission units each have a transmit unit and a receive unit, where the duplex connection includes oppositely directed, unidirectional transmission channels, by which a communications link for each data transmission between respective transmit and receive units of the transmission units is established, during a synchronization phase transmit units independently emit in a periodically repeated manner a first synchronization signal respectively, where following detection and synchronization with the respective first synchronization signal by the respective receive unit, the respective transmit unit belonging to the same transmission unit is instructed to emit at least once a second synchronization signal respectively, where a changeover to data transmission is implemented once the second synchronization signal respectively has been detected at least once by respective receive units of the transmission units.
