  • Method and apparatus for detecting echo cancellers
    Patent number: 6970559
    Abstract: A method is provided for detecting echo cancellation in a communication network. The method includes the steps of transmitting from an originating unit a pre-defined echo cancellation detection signal to a receiving unit. The resulting signal is detected by the receiving unit and analyzed to determine whether the differences between the resulting signal and a stored pre-defined signal indicate the detection of echo cancellation on the communication network.
