ABSTRACT:
A modularly structured digital communication system. The hardware of the communication system is structured in three hierarchic levels. Periphery modules undertake the adaptation to different terminal equipments and lines, whereby connector modules are connected by a module processor control to two PCM lines allocated to a periphery module and to two control information lines respectively. In a pre-processing level, a control information transmission assembly is allocated to each periphery module and respectively two such transmission assemblies have an input/output processor allocated to them. The highest hierarchic level is represented by a central control processor that is connected by a multiplex bus to the input/output processor and to a switching matrix network device.
