METHODS AND APPARATUS TO PERFORM LINE TESTING AT CUSTOMER PREMISES

摘要

A video stream DSL analyzer receives at least non-physical layer management data (e.g. packet lost, corrupted packets) and physical layer management data (e.g. FEC counter, INP, reported data rate, SES counter, CRC counter) and in response generates metric information. The generated metric information is used to characterize the performance of the video stream information and diagnose any problems if necessary. In response to the metric information, the video stream DSL analyser changes one or more DSL configuration(s) in order to improve performance.
