Telco Echo Return Loss (TERL)

The Telco Echo Return Loss meter shows the coupling between the transmit signal and the input to the telephone echo canceller. It is the ratio of the two levels. The range of the meter is -30 to +20dB. It is a peak meter and updates only when transmit signal is present.
