ABSTRACT:
A space division switching network having a plurality of stages is disclosed for use as part of a time-space-time division switching system. The network employs MOS technology with standard printed circuit boards enabling very compact assembly. To enable a maximum number of stages to be placed on a standard board with appropriate electrical connections to each stage over the standard number of terminals, addresses of crosspoints are supplied in parallel over common address conductors and the appropriate stage is then switched through an enable signal.
