Abstract

METODO Y APARATO PARA LA IDENTIFICACION DE CELDAS VALIDAS EN UNA UNIDAD DE COMBINACION DE CIRCUITO REDUNDANTE DE UN INTERRUPTOR DE MODO DE TRANSFERENCIA ASINCRONA. SE PROPORCIONA UN METODO Y APARATO PARA LA IDENTIFICACION DE CELDAS VALIDAS EN UNA UNIDAD DE COMBINACION DE CIRCUITO REDUNDANTE DE UN INTERRUPTOR DE MODO DE TRANSFERENCIA ASINCRONO QUE TIENE PLANOS DE CONMUTACION DUPLICADA. EL METODO CONSTA DE LOS PASOS DE:A) IDENTIFICACION DEL PLANO DESDE EL QUE PASO LA ULTIMA CELDA CON RESPECTO A UNA LLAMADA EN PARTICULAR, B) COMPROBACION DE QUE UN NUMERO DE SECUENCIA ASOCIADO CON LA CELDA NO ES SUPERIOR AL ALMACENADO EN UN MEDIO DE ALMACENAMIENTO, C) COMPROBACION DE QUE LA ULTIMA CELDA QUE PASO EN LA LLAMADA EN PARTICULAR FUE DESDE EL MISMO PLANO, D) COMPROBACION DE SI LA CELDA ES UN DUPLICADO DE LA ULTIMA CELDA EN LLEGAR A ESTE PLANO, Y, E) PASO DE LA CELDA A UN ALMACEN DE SALIDA SI (C) ES VERDAD Y (D) NO ES VERDAD Y ALMACENAMIENTO DEL NUMERO DE SECUENCIA DE LA CELDA EN EL MEDIO DE ALMACENAMIENTO.
