Abstract
An arrangement comprising a host switching system and a number of remote switching modules which are selectively interconnected by a time-multiplexed switch such that voice and data traffic as well as control information is conveyed between modules without being routed through the host system network. The arrangement allows the integrated stand-alone operation of the remote switching modules and advantageously reduces traffic through the host system during normal operation.
