发明名称 Method and apparatus for testing a subscriber loop-based service
摘要 A network interface device is positioned between a subscriber loop and the internal wiring of a subscriber's premise. Operational and performance data is captured and stored in memory for later use and analysis. Commands issued to the network interface device selectively loop-back transmitted data at either the network or subscriber side of the network interface device and/or selectively engage or disengage one or more of the addressed subscriber and premise loops.
