Abstract
A time-space-time switching network is shown in which there is a crossover of voice information from one rail to another rail in a large digital switching system. The time and control unit is divided into two rails both incoming and outgoing. Each rail multiplexes two 193 channel streams into one 386 channel stream of information. These two rails crossover in the terminating time switching stage but remain segregated throughout the space switching stage and the originating time switching stage.
