ABSTRACT:
A communications system (FIG. 7) couples together a number of entities or communications devices 710 by means of alternating stages (722, 726) of crossbar switches (712, 716) and stages (724, 728) of stride extender coupler circuits, which are preferably in the form of modules (714, 718), together with a final stage (730) of cross-connecting "termination" circuits or modules (720). The system can be expanded in performance capability (FIG. 8) by adding further stages (822, 828) of crossbar switches and stride extender coupling circuits or modules.
