ABSTRACT:
A non-blocking exchange switch for communicating information samples between points, including a time slot interchange, a voice conferencing system and a network interchange. The time slot interchange includes an interchange memory having a single storage location associated with each point connected from the switch. A point address memory provides point addresses corresponding to points and associated interchange storage locations. A connection memory provides corresponding connection addresses corresponding to interchange storage locations associated with points with which a point is communicating. The voice conferencing system includes a conference memory means providing conference addresses corresponding to points in a conference connection, and a sample memory means for storing individual samples from corresponding points. A conference processor means provides corresponding conference samples to conference communicating points, each conference sample comprising a summation of individual samples.
