FIELD: communications engineering. SUBSTANCE: proposed system for switching cells in asynchronous transmission mode (ATM) has more than one center connected between line transmitting subscribers' data and type ATM high-speed communication line for executing transfers between subscribers' data and ATM cell, as well as ATM switching unit for receiving ATM cell from one of centers over high-speed communication line, finding address from header information, and routing ATM cell to other center. EFFECT: enhanced speed of switching automatic transmission mode cells. 20 cl, 12 dwg
