In order to reduce the memory requirement, in particular in ATM, the maximum number possible of consumer channels equivalent to one another should be made available. …<??>A combined time, wavelength/frequency and space-division multiplex switching device is known. …<??>Space-division switching stages alternate with time and wavelength/frequency converters. …<??>A multistage switching network comprises identical switching modules (10) which are networked with one another in the conventional manner. Each module contains two space-division switching stages (13, 15), a wavelength converter (141, ..., 14m) and a time converter (121, ..., 12n). …<IMAGE>… |
