Abstract

SISTEMA QUE PERMITE LA SINCRONIZACION DE TODAS LAS INSTALACIONES DE PARTICIPACION EN UNA RED-COMUNICACION. CONSTA DE UN SINCRONIZADOR PRINCIPAL (Z) QUE ESTA DISPUESTO EN EL PUNTO ESTRELLA DE LA RED, QUE EMITE PREVIAMENTE EL RETICULO DE RECEPCION DE TODAS LAS INSTALACIONES DE PARTICIPACION (T). COMPRENDE TAMBIEN UNOS DISPOSITIVOS DE TIEMPO, DISPUESTOS ENTRE LA CONEXION DE CABLES Y LAS INSTALACIONES DE PARTICIPACION, EN LOS QUE EL TIEMPO DE RECORRIDO DE LA SEÑAL DESE UNA INSTALACION DE PARTICIPACION A CUALQUIER OTRA SE HACE IGUAL A UN TIEMPO DE RECORRIDO MAXIMO; EN DICHAS INSTALACIONES DE PARTICIPACION ESTA AVANZADO EL RETICULO DE EMISION FRENTE AL RETICULO DE RECEPCION POR ESTE TIEMPO DE RECORRIDO MAXIMO. DE APLICACION EN EL INTERCAMBIO DE NOTICIAS EN CLAVE.
