Abstract

A switch in a digital PBX system supporting both centralized and distributed switching techniques. The switch has nearly universal parallel bus (10) between line card modules. The bus having a timeslot bus capable of having more than one line card module connected to it, which may communicate voice PCM or data signals during one timeslot. The bus (10) also has a signalling bus (26, 27, 28, 29) by which line card modules are selected to communicate with a central control module by a single line to maintain the universality of the bus (10). Signalling information is also passed between a selected line card module and the central control module by a pair of parallel lines (27, 28).
