Abstract
A common control telecommunications switching system capable of efficiently handling both narrow band and wide band information. The system uses a hybrid digital network having a time division section for switching narrow band signals and a space division section for switching wide band signals. Both networks include connection memories accessible by the central processor for writing connections therein to set up or take down communication paths between selected access ports.
