Abstract
UN TERMINAL (22) PARA UN SISTEMA DE TELECOMUNICACIONES QUE PROPORCIONA UN ACCESO A UNA O DOS LINEAS DE TRANSMISION SINCRONICA DE ALTA VELOCIDAD (10, 12) PARA LINEAS DE TRANSMISION DE BAJA VELOCIDAD (16) Y LINEAS DE ABONADO (20). UN NUCLEO MODULADO INCLUYE INTERFACES (32) PARA LAS LINEAS DE ALTA VELOCIDAD (10, 12) UN INTERCAMBIADOR DE CUOTAS DE TIEMPO (34), UN INTERFACE (42) PARA LAS LINEAS DE TRANSMISION DE BAJA VELOCIDAD (16), PROCESADORES (40) Y CIRCUITO SUPLEMENTARIO (40) PARA APOYAR EL TERMINAL (22). UN MODULO DE ACCESO (26) INCLUYE UNA PLURALIDAD DE ESTANTES DE LINEAS (48) CONECTADOS A LINEAS DE ABONADOS (20); CADA ESTANTE DE LINEA (48) INCLUYE UN PAR DE PROCESADORES (68) Y CUATRO ASIGNADORES DE CUOTAS DE TIEMPO (82). UNA VIA EN SERIE DE MULTIENLACES (44) CONECTA EL INTERCAMBIADOR DE CUOTAS DE TIEMPO (34) AL MODULO DE ACCESO (26) Y AL INTERFACE DE BAJA VELOCIDAD (42) Y PROPORCIONA UN ACOPLAMIENTO ESTRECHO ENTRE LOS PROCESADORES (40) EN EL MODULO DEL NUCLEO (24) Y LOS ESTANTES DE LINEAS(48). LOS PROCESADORES COOPERAN A LA HORA DE PREPARAR LA INFORMACION DEL ABONADO DE DICHAS LINEAS DE ABONADO (20) PARA Y A PARTIR DE CUOTAS DE TIEMPO EN DICHA LINEA DE ALIMENTACION DE ALTA VELOCIDAD (10, 12) Y DICHA LINEA DE BAJA VELOCIDAD (16). TAMBIEN SE PUEDE HABILITAR LA INFORMACION DEL ABONADO ENTRE CUOTAS DE TIEMPO DE LA LINEA DE ALIMENTACION DE ALTA VELOCIDAD (10, 12) Y LAS LINEAS DE TRANSMISION DE BAJA VELOCIDAD (16) ENTRE CUOTAS DE TIEMPO DENTRO DE CADA LINEA DE ABONADO (20).
