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 control includes detector circuitry to detect that one of the inputs has an incoming packet signals for transmission to one of the outputs, includes determining circuitry for determining if the one of the output modules will accept the incoming packet signals, and includes enable circuitry, responsive to the determining circuitry, for enabling the acceptance of the incoming packet signal by the output module for transmission to the output. The control is distributed throughout the switching element in output modules, one module for each output from the switching element.
