发明名称 Method and apparatus for automated asymmetric digital subscriber line loop testing
摘要 A method and apparatus for mechanizing the currently manual ADSL loop testing process is disclosed. In one embodiment, an automated loop testing device is disclosed, where the loop testing device has a pair of terminals, e.g., RJ-11 jacks on both sides of the device. The jack on one side connects to inside wiring which, in turn, connects to an ADSL modem. The other jack connects to an outside line which, in turn, connects to a central office of a network provider. In operation, the present device detects a line voltage reversal and then disconnects the input line to the ADSL Modem. When the voltage returns to normal, then the device behaves normally by being closed, essentially acting as a pass through device and again connects the input lines to the output lines.
