Abstract
The transmission of digital data takes place over a network comprising a data transmission line and a control and synchronizing line connecting together a master station, alone capable of transmitting over the control line, and several slave stations. The two lines are unidirectional and looped back to the master station and the stations transmit information in phase over the two lines. For that, each slave station comprises means for extracting clock information from the signal permanently present on the control line.
