ABSTRACT:
The cell output control apparatus includes a cell time slot allotment circuit for allotting, cells to be transmitted, to cell time slots with the cell transmission intervals changed, a first holder circuit for holding the value of ACR (Allowed Cell Rate), a first calculator circuit for calculating the ratio, LCR (Line Cell Rate)/ACR, a quantizer circuit for quantizing the ratio, LCR/ACR and controlling the allotment of cell time slots on the basis of the quantization error produced by the quantization, a counter for counting the values of cell time slots, a second calculator circuit for calculating the cell time slots for cells, and a second holder circuit for holding the calculated results, whereby it is possible to absorb the quantization error produced when the ratio, LCR/ACR is quantized into an integral value.
