Abstract
PARA ENDURECER TRANSMISIONES EN LOS DOS SENTIDOS ENTRE UNA ESTACION MAESTRA (1) Y UNA ESTACION ESCLAVA (2), SE MEMORIZA EN CADA UNA DE ESTAS ESTACIONES UNA TABLA (7), (14) DE VALORES DE PARAMETROS DE CONEXION QUE HAN SIDO UTILIZADOS SEGUN UNA DECISION DE LA ESTACION MAESTRA. CADA MENSAJE DE UNA ESTACION HACIA LA OTRA CONTIENE LAS INDICACIONES QUE PERMITEN A ESTA ULTIMA DETERMINAR LOS VALORES DE LOS PARAMETROS A ELEGIR EN LA TABLA DE MANERA A ELIMINAR LOS VALORES QUE CORRESPONDEN A UN RIESGO DE INTERFERENCIA IMPORTANTE.
