A clock-synchronous selecting circuit operates at clock intervals for selecting one of the addresses of the line circuits which are generating the proceed-to-send requests according to a predetermined sequence of priorities so that the selected address exists for a time interval which is an integral multiple of the clock interval. A switching network is responsive to the selected address and the destination address for distributing data blocks from the line circuit of the selected address to the line circuit of the destination address through a common bus. | |
