摘要
The invention provides a system and method for testing a telephone or communications line to determine if the line qualifies for a particular type or class of communications service, for example DSL service. In accordance with one embodiment, a potential customer can download a software program. The program first performs a DSL distance qualification calculation. If the customer's line passes this step, the program determines whether the line coupled between the customer and a central office servicing that customer is electrically qualified for DSL communications. A series of tests to measure signal levels, noise, and other characteristics are performed by a test server, which generally include local loop tests to determine the presence of bridged taps, load coils, and subscriber line concentrators. After the tests are completed, the customer can receive the results, order completion and other instructions.
