Because the same pair of wires is used for simultaneous transmitting and receiving (full duplex transmission) the terminal equipment should attenuate its transmitted signal towards its receiver to prevent feedback. Such feedback is called sidetone. Too little sidetone in a handset telephone can conv ...
