ABSTRACT:
A data transmission system for the transmission of time multiplex data between a plurality of stations via the transponder of a communications satellite wherein each pulse frame includes a code sequence (SRUW) periodically transmitted by a reference station and which can be used for synchronization by the other stations, and pulse bundles transmitted by a pedetermined sequence by the other station. A plurality of the stations are utilizable as reference stations but only one is active. Each of the stations which can be used as a reference station periodically transmits its own code sequence at the beginning of successive pulse frames, with the reference stations being synchronized with the coded sequence from the active reference station and the other stations being synchronized with the coded sequence of any of the reference stations. Upon a malfunction in the system so that the coded sequence from the active reference station cannot be received by the other reference stations, the one of the reference stations which is active is changed.
