Abstract
A time-slot interchanger (TSI ) is used to control both time-slot access and distribution of signals to physical or virtual signal-processing circuits ( ). The TSI includes a control table ( ) with an entry ( ) for each time slot, that specifies the source ( ) and destination ( ) of signals received during the corresponding time-slot interval and the processing ( ) of those signals. The TSI is coupled to the signal processing circuits, and sends the received signals to the signal processing circuits for processing along with control signals to effect the processing specified by the corresponding control-table entries. For conferencing, the TSI sends all signals for each conference in sequence to the conferencing circuit ( ) before starting and sending any signals for any other conference, thereby allowing a single conference accumulator to support any number of conferences of any size.
