Abstract
A time-division circuit switch which serves as a cross connect for time multiplexed signals including frames subdivided into slots serves to cross-connect input and output lines on a slot-by-slot basis. The circuit utilizes a self-routing packet switching network. An input interface attached to each input line converts incoming slots into fixed length packets which can be routed through the self-routing switching network in a synchronous manner. An output interface coupled to each output line reconverts the packets into slot/frame format. To prevent blocking, the self-routing packet switching network runs at a faster rate than the input and output lines of the switch.
