Abstract
A method that uses a test system at one end of a communication link to test the communication link for high speed service by coupling the test system to the communication link, placing a telephonic call to telephonic equipment located at an other end of the communication link and testing the communication link with the test system after the call has been terminated at the telephonic equipment.
