A telecommunication system with reduced latency of low bitrate coding transport over, ATM cells. According to the invention the system employs standard ATM cells divided into fractional segments or fractions, the header of each standard ATM cell is also the header, of the first fraction of a divided cell and each successive fraction of the cell has a header, structured as a standard ATM cell header. Always according to the invention the, VPI/VCI value contained in a specified location in the header of the first fraction, identifies the ATM connection multiplexing several low-rate sub-flows as well as the, sub-flow to which the first fraction pertains to while the VPI/VCI values , …
