ABSTRACT:
A time division switching system to which incoming and outgoing transmission channels designed for the transmission of bit streams subdivided into bits are connected. The system has a number N of time division switching stages, a number N of distributors and a number N of collectors, each distributor has N inputs to which an incoming transmission channel is connected, each collector has N outputs to each of which is connected an outgoing transmission channel, each distributor has N outputs, each of the N outputs of a distributor being connected to an input of each of the time division switching stages for a proportionate distribution according to a predetermined pattern of the bit stream of each incoming transmission channel over the N time division switching stages, and each collector has N inputs, each of the N inputs of a collector being connected to an output of each of the time division switching stages for collecting according to a predetermined pattern the bit streams for each outgoing transmission channel.
