Abstract
Abstract Electronic business communication systems are generally comprised of a number of independent switching modules each of which is comprised of a time slot interchange circuit. These time slot interchange circuits are all interconnected by a separate central switching network. The subject switching network control arrangement provides a flexible method of interconnecting the subscribers served by the telephone switching system and, in particular, of summing the conversations of various conferees in a conference call situation to thereby minimize the traffic in the central switching network as well as provide various feature enhancements.
