Abstract
A cell buffer is provided for storage of cells for each quality class. A counter is provided for each cell buffer. A threshold value which regulates the respective readout interval is set for each quality class. The count of the counter for each quality class is increased by 1 for each time slot. When the count for a certain quality class reaches the threshold value, if a cell is stored in the cell buffer for that quality class, that cell is read out and output, and, at the same time, the count is decreased by the threshold value. When the count for a certain quality class reaches the threshold value, if a cell is not stored in the cell buffer for that quality class, the count is left unchanged.
