Abstract
UN SISTEMA DE COMUNICACIONES COMPRENDE UN TERMINAL DE LINEA (1), UNA PLURALIDAD DE TERMINALES DE CLIENTES (2), Y UNA RED OPTICA PASIVA PARA SOPORTAR EL TRAFICO ENTRE EL TERMINAL DE LINEA Y LOS TERMINALES DE CLIENTE. EL TERMINAL DE LINEA (1) TIENE UNA UNIDAD DE TERMINAL (BTS(N)) PARA EL TRAFICO DE ANCHURA DE BANDA RELATIVAMENTE ESTRECHA, Y UNA SEGUNDA UNIDAD DE TERMINAL (BTS(1) A (BTS(N-1)) PARA EL TRAFICO DE ANCHO DE BANDA RELATIVAMENTE MAS ANCHA. SE DISPONE UN MULTIPLEXADOR DE DOMINIO DE TIEMPO (14) PARA MULTIPLEXAR EL TRAFICO DESDE LA PRIMERA A LA SEGUNDA UNIDAD DE TERMINAL PARA LA TRANSMISION CORRIENTE ABAJO SOBRE LA RED (18). CADA TERMINAL DE CLIENTE (2) TIENE UNA PRIMERA UNIDAD DE SERVICIO PARA UN TRAFICO DE ANCHO DE BANDA RELATIVAMENTE ESTRECHA Y UNA SEGUNDA UNIDAD DE SERVICIO PARA EL TRAFICO DE ANCHO DE BANDA RELATIVAMENTE MAYOR. CADA TERMINAL DE CLIENTE (2) TIENE UN DESMULTIPLEXOR (22) DISPUESTO PARA RECIBIR EL TRAFICO MULTIPLEXADO DESDE LA RED (18), Y PARA SEGREGAR EL TRAFICO ENTRELA PRIMERA Y LA SEGUNDA UNIDAD DE SERVICIO. CADA TERMINAL DE CLIENTE (2) TIENE MEDIOS DE CONTROL PARA GENERAR SEÑALES DE CONTROL DE UN ANCHO DE BANDA RELATIVAMENTE ESTRECHO PARA LA TRANSMISION CORRIENTE ARRIBA SOBRE LA RED, LA SEGUNDA UNIDAD DE TERMINAL (BTS(1) A (BTS(N-1)) DEL TERMINAL DE LINEA (1) ES SENSIBLE A LAS SEÑALES DE CONTROL DE UN TERMINAL DE CLIENTE DADO (2) PARA CONTROLAR LA TRANSMISION DEL TRAFICO DE UN ANCHO DE BANDA RELATIVAMENTE MAYOR A ESE TERMINAL DE CLIENTE. LA TRANSMISION CORRIENTE ABAJO ES MEDIANTE TDM Y LA TRANSMISION CORRIENTE ARRIBA ES MEDIANTE TDMA.
