Abstract
A data transmission system has a time interval allocation system with a time interval management unit (UGIT) and a plurality of counters (CSO.sub.1 to CSO.sub.n) connected to one another in a cascaded series. The input of a counter (CSO.sub.i) is connected to the output of the preceding counter (CSO.sub.i-1) in the series. The input of the first counter (CSO.sub.1) is connected to the output of the time intervals management unit. Each counter (CSO.sub.i) is associated with an input carrying a time interval allocation demand signal (dem.sub.i) and provided with a command input for receiving the allocation demand signal (dem.sub.i) and delivering either the time interval value (ITin) present on its input if the allocation demand signal (dem.sub.i) is inactive, or the time interval value present on its input increased by a unit (ITin+1) if the demand signal (dem.sub.i) is active. The output of each counter (CSO.sub.i) is connected to the input of a register (RegAd.sub.i), having a command input for receiving the corresponding demand signal (dem.sub.i). Then, each register (RegAd.sub.i ) delivers an allocated time signal (ITa) if the corresponding demand signal (dem.sub.i) is active.
