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.
Claims5
An exchange comprising a digital switching network (TS, AS, PS) and peripheral units (TO, . . . , T6143), said peripheral units being connected to said switching network by switching elements, said peripheral units serving to interface with subscribers, other exchanges, or maintenance devices, and said switching network serving to establish arbitrary traffic relations between said peripheral units, particularly to establish switched connections between attached subscribers or exchanges, characterized in that at the switching element (TCEO, . . . , TCE6143) connected between at least one of said peripheral units and said switching network, the maximum traffic rate between the switching element and said switching network is more than twice the maximum traffic rate between said at least one of said peripheral units and the switching element.
