Abstract
UNA INSTALACION DE INTERCOMUNICACION SIMPLEX O DUPLEX CONTROLADA POR TECLADO CON SELECCION DE LINEA. EN UNA CENTRAL HAY CONECTADOS VARIOS EQUIPOS DE ABONADOS. LA INTERCONEXION DE LAS VIAS DE LLAMADA Y ENLACE ASI COMO LA DETERMINACION DEL ESTADO DE OCUPACION DE LOS EQUIPOS DE ABONADOS SE CONTROLA MEDIANTE UN ORDENADOR DE COMUNICACION DISPUESTO EN LA CENTRAL. LOS EQUIPOS DE ABONADOS ESTAN CONECTADOS A LA CENTRAL MEDIANTE UNA VIA DE TRANSMISION DIGITAL EN SERIE, A TRAVES DE LAS QUE SE TRANSMITEN TANTO LAS SEÑALES DE CONTROL Y LAS SEÑALES DE ESTADO DE OCUPACION COMO TAMBIEN LAS SEÑALES VOCALES EN FORMA DIGITAL EN MULTIPLEX DE TIEMPO. LA ESTRUCTURA DE CANALES DE LA VIA DE TRANSMISION POSEE DOS CANALES B CON UNA VELOCIDAD DE TRANSMISION RESPECTIVA DE 64 KBIT/S. EN CADA DIRECCION Y UN CANAL D CON UNA VELOCIDAD DE TRANSMISION DE 16 KBIT/S. TODAS LAS SEÑALES VOCALES SON TRANSMITIDAS A TRAVES DE LOS DOS CANALES B Y TODAS LAS SEÑALES DE CONTROL Y LAS SEÑALES DE ESTADO DE OCUPACION A TRAVES DEL CANAL D.
