Telephone communication device MCQ - Practice Questions with Answers

The mouthpiece is the speaking part of a telephone. It receives the user’s voice and converts the sound information into a signal for transmission through the telephone system. The receiver performs the opposite function by reproducing incoming sound for the listener. A cable only carries signals between parts or across the network; it does not accept the voice directly. A dialer is used to enter or select the called number, so it is linked with connection setup rather than voice conversion.
