Abstract
SISTEMA DE MULTICONFERENCIA. EL SISTEMA OBJETO DE LA INVENCION, CUYA FINALIDAD ES LA REALIZACION DE VARIAS CONFERENCIAS SIMULTANEAS, MINIMIZANDO LA PRESENCIA DE LA SEÑAL TRANSMITIDA EN EL CANAL DE RECEPCION CORRESPONDIENTE, ESTA CONSTITUIDO POR LA ASOCIACION FUNCIONAL DE UNA SERIE DE HIBRIDAS DIGITALES (1) QUE SIRVEN DE LAZO DE UNION ENTRE UNA MATRIZ DE CONMUTACION (2) CON UNIDADES DE CONTROL REMOTO (3). LA FUNCION DE CONTROL LA REALIZA UNA UNIDAD MICROCONTROLADORA (4) A TRAVES DE UN BUS DE CONTROL (13) Y DE UN INTERFACE (5) PARA HIBRIDAS (1) / MATRIZ DE CONMUTACION (2) Y UNIDADES DE CONTROL REMOTO (3) RESPECTIVAMENTE.
