Abstract

PURPOSE:To realize various operating modes of a conference telephone set not realized by a conventional technology by applying all rolls fulfilled by the conference mode belonging to its channel in time division within a time of one time slot given to each channel. CONSTITUTION:A conference number register 21 and a conference mode register 22 are scanned by a channel counter 25 representing the same channel number in the same rate as an input PCM signal and output a conference number signal and a conference mode signal corresponding to each channel. A control register 23 receives all entered signals at its address and applies a control signal specified by each conference mode into a micro code. Then the register 23 uses an output of the conference number register 21 to apply address designation to a final channel register 24, reads the output signal of the channel counter 25 for each channel within one time slot and then writes it as the scanning, the output and the output of channel write 25 are observed by a number coincidence detection circuit 26 to inform the final channel number to each conference group.
