Communication branch exchange for voice and/or data communication services

摘要

This branch exchange consists of a switching unit with central processor, a switching network and access unit, of subscriber terminals for the voice and/or data communication service and of at least one peripheral storage unit (SM) connected to the access unit for receiving communication service information. According to the invention, each peripheral storage unit (SM) in each case exhibits an interface module (LU) which consists of spatially separate service-specific and non-service-specific module sections (SU; PU, LU). The service-specific module sections (SU) are arranged on subracks which can be connected to the remaining module sections of the interface module (LU) by means of plug-in connection arrangements. <IMAGE>
