Abstract

UNA BANDA ANCHA BIDIRECCIONAL Y UNA RED TELEFONICA CONTROLABLE DESDE EL EXTREMO DE INTERCAMBIO 15. UNA FIBRA OPTICA 16 LLEVA LOS SERVICIOS A LAS CASAS DE LOS CLIENTES 30, 31 VIA SEPARADORES OPTICOS PASIVOS 17, 18. LA TELEFONIA DESDE EL BLOQUE 10 SE PROVEE EN UNA LONGITUD DE ONDA, LA DIFUSION DE LA TV DESDE EL BLOQUE 11 EN UNA SEGUNDA LONGITUD DE ONDA, E INFORMACION DE DIVISION DE TIEMPO ASINCRONA BIDIRECCIONAL DESDE EL BLOQUE 40 EN OTRA LONGITUD DE ONDA USANDO TECNICAS ATD (DIVISION ASINCRONA DE TIEMPO) . LOS INTERVALOS DE TIEMPO SE LOCALIZAN EN PAQUETES DE INFORMACION Y ASI PUEDEN VIAJAR SIN INTERFERIR Y SE AJUSTA EL CICLO DE RETRASO ENTRE ESTACIONES DESDE LAS ESTACIONES RECEPTORAS PARA ASI ALCANZAR REQUERIMIENTOS MINIMOS DE MANTENIMIENTO DEL ANCHO DE BANDA MIENTRAS. LA LOCALIZACION DINAMICA DE CAPACIDAD DE RESERVA SE PROVEE PARA SERVICIOS CARGADOS.
