The invention describes a network for switching high-speed terminals to computer ports. A space division network is used today, wherein a central control accepts the terminal's requests and establishes a path to connect them to the desired computer port. This path stays closed until the terminal requests the termination of the connection. While the path is closed, data is transmitted for less than 1% of the time, in high-speed bursts. A more efficient way to use network resources would be for the path to be closed long enough for the burst to be transmitted, and then to free the path links for other transmission. This increased efficiency is translated into a drastic reduction in implementation hardware. For example, the 2048-line DDX space division network requires 256 matrix switches.
