摘要： The present invention discloses a system for testing subscriber lines and method thereof. The system includes a broadband line testing control module and a remote terminal subscriber access control module located at a subscriber line that is located between the broadband line testing control module and a remote terminal unit. The broadband line testing control module sends a signal of disconnecting the subscriber line to the remote terminal subscriber access control module, and tests the subscriber line. The remote terminal subscriber access control module receives said signal from the broadband line testing control module, and controls the remote terminal unit to disconnect from or connect to the subscriber line based on said signal. With the system and method according to the present invention, not only the precision of subscriber line testing is guaranteed, but also the subscriber lines can be periodically tested without manual operation.
