<p>An automatic telecommunication switching system handles all communications, whether voice or data, in packet switching manner. The switching network consists of a multi-stage network of co-ordinate matrix elements each of which has memory and processing means. Such an element is a single-chip VLSI device. Each packet has a header which includes the address of the network outlet to which that packet is to be routed, each such address consisting of a digit for each stage via which the packet is to be routed. At each matrix element the appropriate digit of that address is used to route the packet to the appropriate outlet from the matrix element.</p> |
