ABSTRACT:
A method for testing subscriber loop conditions includes receiving test signal data from a test signal provider, receiving a request for transmitting a test signal described by the test signal data, and transmitting the test signal over a communication channel. The test signal may correspond to a pre-qualification test signal, a qualification test signal, or an in-service test signal. Test results may be transmitted to the test signal provider or to some other designated recipient.
