Abstract

SE PRESENTA UNA ESTACION TERMINAL DE CABECERA (1) PARA UN SISTEMA DE RED OPTICA PASIVA DISPUESTA PARA TRANSMITIR Y RECIBIR ESTRUCTURAS DE DATOS MULTIPLEX. LAS ESTRUCTURAS DE DATOS INCLUYEN UNA PLURALIDAD DE ESTRUCTURAS BASICAS (BF), CADA DE LAS CUALES COMPRENDE UNA PLURALIDAD DE BITS DE TRAFICO Y UNA PLURALIDAD DE BITS DE CONTROL. LA ESTACION TERMINAL DE CABECERA (1) INCLUYE UN RECEPTOR DE DATOS QUE COMPRENDE UN PROCESADOR DE CONTROL (12) DISPUESTO PARA RECIBIR LOS DATOS DE CONTROL, UN "BUFFER" DE DATOS DE CONTROL (13, 14) QUE SUMINISTRA UNA ENTRADA DE DATOS EN PARALELO AL PROCESADOR DE CONTROL, UNA "INTERFACE" DE TRAFICO (15) Y UN CONVERSOR SERIE A PARALELO (11). EL CONVERSOR (11) RECIBE LAS ESTRUCTURAS MULTIPLEXADAS TDMA Y LA SALIDA EN PARALELO DEL CONVERSOR SE CONECTA EN PARALELO A LAS ENTRADAS RESPECTIVAS DEL "BUFFER" DE DATOS (13, 14) Y DE LA "INTERFACE" DE TRAFICO (15). UN TRANSMISOR DE DATOS PARA DICHA ESTACION TAMBIEN INCLUYE UN PROCESADOR DE CONTROL (12''), UN "BUFFER" DE CONTROL (13'', 14'') Y UNA "INTERFACE" DE TRAFICO (15''). UN CONVERSOR PARALELO A SERIE RECIBE LOS TDMA. LA ENTRADA EN PARALELO AL CONVERSOR SE CONECTA EN PARALELO AL "BUFFER" DE DATOS DE CONTROL (13'', 14'') Y A LA "INTERFACE" DE INTERCAMBIO (15''). EN UN ASPECTO MAS ADECUADO DE LA INVENCION, LAS ESTRUCTURAS TDMA INCLUYEN UNA ZONA DE CABECERA (H) QUE PRECEDE A LA PLURALIDAD DE ESTRUCTURAS BASICAS (BF) Y LOS "BUFFERS" DE LOS DATOS DE CONTROL (13, 14, 13'', 14'') ESTAN DISPONIBLES TANTO DURANTE LA ZONA DE CABECERA COMO DURANTE LAS PARTES DE LAS ESTRUCTURAS BASICAS QUE CONTIENEN LOS BITS DE CONTROL.
