Abstract

A binary counter consecutively delivers as addresses all channel numbers of the exchange. A register storing speech signals of a channel is marked by the counter before their switching. A comparator receives signals after switching and those stored in the register. In case of noncoincidence it sets a flip-flop, and in the case of coincidence it switches forward the counter. Devices which compare channel addresses generated by the counter with those delivered by clock controlled exchange units. They coordinate in time the comparison of speech signals of the selected channel, taking into consideration propagation time in the exchange, and their respective position in time.
