Abstract:
A method for testing telecommunications equipment over which two-way speech traffic can be carried between a first test point and a second test point, the method comprising;a) generating first and second test signals representative of normal conversation, and each having a predetermined vocal level, b) transmitting the first test signal from the first test point to the second test point, c) simultaneously transmitting the second test signal from the second test point to the first test point, d) measuring the quality of the test signals received at the respective test points, e) determining a vocal level adjustment to be made in response to the quality measured at each test point, and f) adjusting the vocal levels of the first and second test signals, the said steps being repeated until a predetermined condition is reached, and an output being generated when said predetermined condition is reached, the output being indicative of the quality measured; wherein the quality measurement uses a perceptual analysis process which measures the extent to which the received signals carry distortions which would be perceptible to a human listener.
