ABSTRACT:
The present disclosure provides a system and method for detecting faults related to lines linked to provide network services. The method includes storing a synthetic value for the performance of a line, receiving a measured value of a performance parameter of the line measured at a customer end and comparing the synthetic value with the measured value to determine if a fault condition exists.
