Information with random traffic volume is preferably trans- mitted in packet form over virtual circuits, with the packets being equal in length. In a packet-switching facility it may happen that two or more packets intended to be forward- ed on the same line arrive simultaneously on different lines. Therefore, buffers must be provided in which the packets that cannot be forwarded immediately can wait. The amount of storage needed for this purpose, besides depending on the length of the packets, depends particularly on the number of incoming lines, the type of traffic, and the re- quired transmission quality. In prior-art packet-switching facilities, about 80% of the area of all chips in the switching network are used for these buffers. According to the invention, 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.
