Abstract
CIRCUITO DE TASACION DE LA CALIDAD DE TRANSMISION PARA UN SISTEMA DE CONMUTACION DE TELECOMUNICACION EN DONDE SE TRANSMITE UN FLUJO DE CELULAS DE INFORMACION DESDE UNA ENTRADA (I) A UNA SALIDA (O) SOBRE UNA MISMA VIA DE COMUNICACION. ESTA ADAPTADO, A LA ENTRADA PARA INSERTAR ESPINTESOMETROS EN EL FLUJO DE CELULAS QUE TENGA CADA UNO UNA ETIQUETA INDICATIVA DE SU POSICION EN EL FLUJO DE CELULAS RESULTANTE Y PARA CALCULAR, A LA SALIDA, LA POSICION DE CADA ESPINTEROMETRO EN EL ULTIMO FLUJO DE CELULAS. DE LA DIFERENCIA DE LA POSICION CALCULADA Y LA ALMACENADA EN CIRCUITO DERIVADO DE UN ESPINTEROMETRO SE DERIVA UNA INDICACION DEL NUMERO DE CELULAS AÑADIDAS O PERDIDAS INDICATIVO DE LA CALIDAD DE TRANSMISION.
