Abstract

Groups of N incoming and outgoing multiplex highways and P incoming and outgoing supermultiplex highways are each formed of N multiplex highways and have aN time slots where a is the number of time slots in a multiplex highway. The supermultiplex highways are multiplexed two by two and with themselves to form double supermultiplex highways each having 2aN time slots. Thus there exists a double supermultiplex highway simultaneously containing any time slot assigned to a calling party and any time slot assigned to a called party whatever be these time slots. The buffer stores of the switching network unit can thus be rendered bidirectional and their number is P(P+1)/2 instead of P2 in the prior art.
