Method and system for positioning of the characterization and line failure of line micro filter state to the network interface device

摘要

Is a system and method for the probe and / or monitoring DSL activity on the line from the CPE side. In an embodiment, the detected PSTN (Public Switched Telephone Network) line conditions is associated with a line data collected to determine the state of the microfilter on the line. Other line failure location is positioned relative to the dry and based on the estimation of in or NID location based on a comparison of the active CPE line NID (Network Interface Device).
