Abstract

Se sincroniza una transmision, en un conmutador basado en células, de células de usuario que pueden incluir numero diferentes de bits de datos. La transmision se lleva a cabo por medio de un enlace bilateral entre entidades funcionales que incluyen cada una, una funcion de control de enlace que contiene funciones para iniciar y controlar la transmision de datos en el enlace por medio de células de sincronizacion que se intercambian entre las funciones de control de enlace. El intercambio de células de sincronizacion se controla por medio de una máquina de estados de sincronizacion que tiene tres estados (304, 308, 312). En un estado BUSQUEDA (312), la funcion de control de enlace investiga una célula de sincronizacion que proviene del enlace para establecer si corresponde con un patron predeterminado para células de sincronizacion. En un estado de PRESINCRONIZACION (304), que empieza después de haberse encontrado una célula de sincronizacion que contiene el patron predeterminado en el estado de BUSQUEDA, la funcion de control de enlace investiga un numero predeterminado de células de sincronizacion consecutivas que llegan después para establecer si contienen el patron predeterminado. Si no es el caso, el proceso de control regresa al estado de BUSQUEDA. En un estado de SINCRONIZACION (308) que inicia después de haberse encontrado un numero predeterminado de células de sincronizacion que contienen un patron predeterminado en el estado de PRESINCRONIZACION, se admite la transmision de datos en el enlace mientras se supervisan los datos en cuanto a errores. Si se encuentran errores, el proceso de control empieza otra vez en el estado de BUSQUEDA.
