ANALOG TELEPHONE SET

PURPOSE:To realize the prevention of deterioration in a signal level and the reduction of unbalance in side tone at the time of simultaneously using plural branch-connected telephone sets. CONSTITUTION:A hybrid circuit 7, a receiving amplifier 8 and a transmitting output stage 12 are provided in a call circuit 6 which is connected to a hook switch 3 and a branch detecting circuit 13 which controls the transmitting output stage 12 of the call circuit 6 is provided. When the branch detecting circuit 13 detects the on-hook of another telephone set which is branch-connected, the impedance of the transmitting output stage 12 which shoulders the impedance as the telephone set is controlled.
