ABSTRACT:
In an arrangement for transmitting digital data signals between subscriber stations which are connected to a common data and control line, each subscriber station contains a clock generator with all clock generators synchronized via a common clock line. The station sending data signals switches the data during a given clock phase to the data line, and the stations receiving data likewise accept the data during a given clock phase. All clock generators are held in the given clock phase until data are accepted so that all clock generators are synchronized to the slowest clock.
