High capacity time connection networks

A time connection network of the kind comprising p switching units having each an input buffer store and an output buffer store, and a space stage to transmit digital information in form of words or groups of n binary digits from one input buffer store toward one output buffer store at a rate of one word per digit time slot, comprising means for serially transmitting the information signals read in an input buffer store, means for transmitting clock signals at the rate of said series transmission, means for generating a rectangular signal having a period of m words, preferably of two words, means for distributing information signals and clock signals in two paths A and B, one path being gated by the leading edges of said rectangular signal and the other path by the trailing edges of the same signal, means for serial-to-parallel converting the information signals controlled by said clock signals, means for re-phasing the transmitted signals, controlled by said rectangular signal, serial-to-parallel conversion and re-phasing being carried out in each path, and means for multiplexing signals from paths A and B and transmitting them to an output buffer store.
