Abstract
SISTEMA DE INTERCAMBIO DE COMUNICACIONES AUTOMATICO. INCLUYE UNA CENTRAL DE CONMUTACION CENTRAL, TAL COMO UNA CENTRAL TELEFONICA, CON SUS LINEAS DE ABONADOS Y QUE PUEDE CONECTARSE A UNA RED DE COMUNICACIONES, Y UN DISPOSITIVO DE CONMUTACION ADICIONAL QUE INCLUYE AL MENOS UN CIRCUITO DERIVACION QUE SE PUEDE CONECTAR A UNA RED DE COMUNICACION, TAL COMO UN CIRCUITO EN ANILLO CERRADO CON DOS VIAS DE TRANSMISION, UNA PARA LA TRANSMISION EN EL SENTIDO DEL RELOJ Y OTRA EN EL SENTIDO CONTRARIO AL DEL RELOJ. EL CIRCUITO DERIVACION INTERCONECTA UNA PLURALIDAD DE TERMINALES DISTINTOS A LAS LINEAS DE ABONADOS, TALES COMO DISPOSITIVOS DE PROCESAMIENTO DE INFORMACION, ESTANDO CONECTADO CADA TERMINAL AL CIRCUITO MEDIANTE UNA UNIDAD INTERFAZ. ALGUNAS DE LAS UNIDADES DE INTERFAZ CONECTADAS AL CIRCUITO DERIVACION PUEDEN ESTAR CONECTADAS TAMBIEN A LA CENTRAL. PUEDE INCLUIR TAMBIEN OTROS TERMINALES INTERCONECTADOS COMO UNA RED EN MALLA ACOPLADA A UNO O VARIOS DE LOS CIRCUITOS DERIVACION Y A LA CENTRAL.
