Abstract
A telecommunication system performs multihop TASI over every hop with a single instance of speech activity detection for each voice call. The system utilizes a Time-Space-Time circuit switch interposed between an input and an output trunk. The input time stage is configured to collect call samples from the input trunk and to map the physical slots associated with the samples to the switch slots of the conventional space switch portion of the circuit switch portion of the circuit switch. In-b signalling of the active state of a switch slot is provided by the input time stage to the output time stage via the space switch. The output time stage is configured to assign physical slots on the outgoing trunk to active switch slots and to discard inactive switch slots.
