Abstract

Fixed numbers of packets are combined into frames within the switching facility, and all packets are divided into subpackets of equal length and distributed to subframes. Switching takes place on the basis of subframes using synchronous time-division multiplexing. The amount of storage space needed in the switching network is reduced in the ratio of frames:subframes. The buffers are those which are necessary for synchronous TDM switching anyhow.
