Abstract

Abstract Translated from German Um den Speicherbedarf, insbesondere bei ATM zu reduzieren, sollen möglichst viele untereinander gleichwertige Abnehmerkanäle zur Verfügung stehen. Kombiniertes Zeit-, Wellenlängen-/Frequenz- und Raummultiplexkoppelelement ist bekannt. Raumkoppelstufen wechseln ab mit Zeit- und Wellenlängen-/Frequenzumsetzern. Mehrstufiges Koppelnetz von untereinander gleichen Schaltmodulen (10), die in üblicher Weise untereinander vernetzt sind. Jedes Modul enthält zwei Raumkoppelstufen (13, 15), einen Wellenlängen-(141, ..., 14m) und einen Zeitumsetzer (121, ..., 12n). <IMAGE> In order to reduce the memory requirement, in particular in the case of ATM, as many customer channels that are equivalent to one another should be available. Combined time, wavelength / frequency and space division multiplexing coupling element is known. Room coupling stages alternate with time and wavelength / frequency converters. Multi-stage coupling network of mutually identical switching modules (10) which are networked with one another in the usual way. Each module contains two space coupling stages (13, 15), a wavelength (141, ..., 14m) and a time converter (121, ..., 12n). <IMAGE>
