摘要: A method of making conference call connections in computer-controlled telephone exchanges includes combining voice signals participants on a digital basis, forming signal total speaking levels given number the most active participants, distributing an undamped manner, and suppressing inactive participants. bit stream reaching assembly through incoming line is distributed to m adding processors having n channels each, PCM words are linearized with code table stored level memories for each particular participant. linear values formed, added individual participant evaluation totals The transmitted processor which determines by using delayed mean value transmits it processors. created all channels. Transmission formed compressing signal, being substracted before compression. thus transmitting outgoing line.
