された信号を上記端末器に伝送する専用線路、この専用
線路に接続され、上記信号の伝送中に上記専用線路に発
生する線路損失を測定して、所定の損失値との差異に応
じた補正信号を送出する線路損失の測定回路、上記専用
線路端と上記端末器の入力端との間に接続され、上記測
定回路より入力した補正信号に応じて利得を補正して、
上記専用線路端より入力した上記信号を所定の出力に調
整して上記端末器に送出する利得の調整回路を備え、上
記専用線路の線路損失が変動しても上記端末器の出力変
動を防止する自動利得制御回路。A dedicated line connected between a transmitter and a terminal and transmitting a signal sent from the transmitter to the terminal, a line connected to this dedicated line and generated on the dedicated line during transmission of the signal. A line loss measurement circuit that measures loss and sends out a correction signal according to the difference from a predetermined loss value, connected between the dedicated line end and the input end of the terminal, and input from the measurement circuit. The gain is corrected according to the corrected signal,
A gain adjustment circuit is provided to adjust the signal input from the end of the dedicated line to a predetermined output and send it to the terminal, thereby preventing output fluctuations of the terminal even if the line loss of the dedicated line changes. Automatic gain control circuit.
