Abstract

PURPOSE:To dynamically and flexibly determine the number of conference groups and the number of conference participants by writing the transmission signal from each subscriber in a memory area corresponding to each subscriber and reading out and adding contents of a designated conference room memory area and subtracting contents corresponding to a designated subscriber. CONSTITUTION:After transmission signals of all subscribers transmitted through an input highway 1 are stored in memory areas of 1 channel memory 3, the transmission signal of the subscriber designated for conference speech and contents held in the address of the conference room memory area corresponding to this subscriber in the channel memory 3 are added by a conference operation circuit 6. After the addition result is written again in the address part of the conference memory area, the transmission signal of the subscriber designated for conference speech which is held in the memory area of the channel memory 3 is subtracted from contents held in the address of the corresponding conference room memory area by a conference operation circuit 7, and the subtraction result is sent onto an output highway 5 as the reception signal of said subscriber.
