Abstract

Un método prueba la línea de abonado. Incluye proporcionar un clasificador para predecir una característica de rendimiento de la línea basado al menos en parte en el valor de una variable auxiliar. Cada valor de la variable auxiliar representa una propiedad de la línea. El método también incluye realizar mediciones eléctricas sobre la línea de abonado, utilizando las mediciones para predecir un valor de la variable auxiliar, y predecir la característica de rendimiento de la línea. El acto de predecir la característica aplica el clasificador al valor predicho de la variable auxiliar. Se aplica en telefonía y transmision de datos.
