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.
Claims21
A method for detecting echo cancellation in a communication network, the method comprising:
- transmitting from an originating unit a pre-defined echo cancellation detection signal to a receiving unit;
- detecting a resulting signal after transmission;
- and
- analyzing the resulting signal 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.
A system for detecting echo cancellation in a communication network, the method comprising:
- means for transmitting from an originating unit a pre-defined echo cancellation detection signal to a receiving unit;
- means for detecting a resulting signal after transmission;
- and
- means for analyzing the resulting signal 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.
A computer-readable medium having encoded therein computer-executable instructions for performing a method for detecting echo cancellation in a communication network, the method comprising:
- transmitting from an originating device a pre-defined echo cancellation detection signal to a receiving device;
- detecting a resulting incoming signal after transmission;
- analyzing the resulting signal to determine whether the difference between the resulting signal and a stored predefined signal indicate the detection of echo cancellation on the communication network.
A system for performing the method for detecting echo cancellation in a communication network, the system comprising:
- transmitter programmed to transmit a pre-defined echo cancellation detection signal from an originating unit to a receiving unit,;
- signal comparator to detect a resulting signal after transmission, and to analyze the resulting signal to determine whether between the resulting signal and a stored pre-defined signal indicate the detection of echo cancellation on the communication network;
- and
- memory in which the predefined signal is stored for comparison with the resulting signal.
