Abstract: PURPOSE: To allow the channel switch to accommodate even a service at a super transmission rate by feeding back grouped cells to an input processing means when the cells make a switching request in excess of a channel capacity. CONSTITUTION: An input processing 21 conducts read control of cells received externally, synchronization adjustment between the externally received cells and cells blocked and fed back by a trap section 23, and transmission control of switching control data to a channel grouping section 22. The grouping section 22 outputs input cells in a same group among received switch control data to consecutive output ports for grouping. The track section 23 discriminates whether or not the grouped cells make a switching request in excess of a concerned channel capacity and feeds back the cells making a switching request in excess of a concerned channel capacity to the input processing section 21 so that the cells are received by the switch simultaneously with cells received externally at a succeeding cell time.
