A communication system includes a plurality of digital signal transmission systems each connected to the next by a repeater installation. Signal packets travelling from a station in one system to a station in another adjacent system are picked out by a repeater station and stored in a buffer memory. The contents of the memory are compiled into a packet for transmission to the other system, with an address designating the station of the other system, and are inserted into an empty block or blocks of a periodically repeated frame of the other system with a waiting time of less than one complete frame.
