13. SPEECH NETWORKS FOR TELEPHONE SETS Abstract of the Disclosure A speech network for a telephone set including a receiver circuit and a transmitter circuit connected in parallel between a tip lead and a ring lead. An amplifying transistor can be connected in either of two modes, including a normal receive mode for amplifying received signals from the line and applying the amplified receive signal to the receiver circuit. A voice-operated switching unit is provided for sensing a voice-signal output from the transmitter and connecting the transistor in a transmit mode, in which the transistor amplifies the transmitter output for transmission to the line. A sidetone generating circuit is connected in parallel with the receiver circuit in the transmit node, for applying a reduced portion of the amplified transmit signal to the receiver.
