In an ATM cell multiplexing apparatus for assembling data, which arrives from multiple terminal lines, into cells, time-division multiplexing the cells and transmitting them to a network, traffic management is performed in each cell assembler, based upon service category and traffic, for every channel accommodated by the terminal lines, and traffic management on a per-cell-assembler basis is performed in an ATM bus scheduler taking into consideration service categories and traffic of all channels accommodated by the cell assemblers. Further, the ATM bus scheduler creates a main schedule table and a subschedule table, which is referred to after the main schedule table, for allocating more transmission privileges to a cell assembler that accommodates a CBR channel, and grants transmission privileges to the cell assemblers upon referring to the main schedule table and subschedule table.
