Multiple access communication system including: a central unit (10); a plurality of peripheral units (20-20), connected to the central unit through a connecting means to which fix-length data packets are transmitted from said central unit (10) to said peripheral units (20-20), and vice versa. According to the invention, said connection means includes: a first, dedicated, monodirectional data connection (70) (Cell_Start_DN, Data_Clk_DN, Data_DN), where the transmission of each data packet is made in a first fixed time period (T1); a second connection (60) including a monodirectional data connection (610) and a bi-directional control connection (620), where the transmission of any one of the data packets is made in a fixed second time period (T2). Thanks to the particular configuration of the above-mentioned connection means, it is possible to supply a flexible central control in the direction going from the peripheral units (20-20) to the central unit (10) in order to limit the cost of peripheral units. The invention enables to limit the processing complexity at central unit level (10).
