ABSTRACT:
An exchange having a digital switching network and peripheral units connected thereto, the peripheral units serving to interface with subscribers, other exchanges, or maintenance devices or to perform other functions, and the switching network serving to establish arbitrary traffic relations between the units, particularly to establish switched connections between attached subscribers or exchanges, characterized in that at the interface to the peripheral units, the digital switching network is overdimensioned more than twofold. The switching network may advantageously be an ATM switching network, and the interface between the switching network and the peripheral units may have narrow-band and broadband inputs and outputs.
