Method for the detection of conditions or failures in telephone lines of the subscriber.Method for the creation of a sequence of classifiers for the detection of faults of line and device for storing program used for that method.A method of testing a subscriber line.The method includes providing a classifier to predict the performance characteristic of the line based at least in part in a value of an auxiliary variable.Each value of the auxiliary variable represents a property of the line.The method also includes performing electrical measurements on the subscriber line using the measurements to predict the value of the auxiliary variable, and the prediction of the performance characteristic of the line.The Act provides for the characteristic applies the classifier to the expected value of the auxiliary variable.Alkyl radical, cicloalquila, alquinila, cianoalquila alcoxicarbonila, aralcoxicarbonila or (cicloalquil) oxicarbonila and R ^ 48 ^ represents a hydrogen atom or an alkyl radical.Alquinila or cianoalquila.
