Abstract
A space stage for a T-S-T digital switching system is shown arranged into four identical space stage units (SSU). Each SSU is arranged into modular functional elements. The elements are combined in each SSU to allow the space stage to grow modularly, interconnecting from thirty-two to sixty-four originating time and terminating time stages.
