Abstract
A self-routing switching element in a packet switch functions in a packet synchronous mode in which a plurality of the incoming packet signals are switched by the switching element concurrently during a common time period. For each incoming packet signal received during the common time period, the switching element detects that one of the inputs has an incoming packet signal for transmission to one of the outputs, determines if the one of the output modules will accept the incoming packet signals, and responsive to the determination, enables the acceptance of the incoming packet signal by the output module for transmission to the output. The control circuitry is distributed throughout the switching element in output modules, one module for each output from the switching element.
