摘要： PURPOSE:To prevent mis-adjustment due to noise and to improve the reliability and operability by detecting a PB signal level transmitted from a pushbutton dial telephone set and adjusting automatically a storage or reproduction level based on the detected level. CONSTITUTION:In storing a sound message or reproducing it to/from a voice storage reproducing device VRS, after a subscriber connects a pushbutton dial telephone set T to the VRS via an automatic exchange SW, the control information is transmitted by a PB signal according to the command from the VRS. A level detector LDT of the VRS detects the PB signal level. Then a processor PU calculates the attenuation from the PB signal level to the telephone set T and the level adjusting information correcting the attenuation is set to a voice level control register VCR. An analog digital converting section CNV applies level adjustment based on the level adjustment information set afterward.

摘要： PURPOSE:To reduce the number of circuits for adjusting a sound transmission level by providing a sound transmission level adjusting circuit between a sound transmitter and a switch for forming a circuit network and adjusting the sound transmission level with the aid of a control signal from a controller. CONSTITUTION:The level adjusting of sounds transmitted from a sound transmitter 4 is executed in signal processors 7a and 7b, while the level setting is carried out by the arithmetic processing of a sound signal and values which a controller 8 writes in a RAM of the processors 7a and 7b. The value which the controller 8 writes in the RAM of the processors 7a and 7b is decided by an attenuating amount of a circuit led to an input trunk, and half fixedly inputted to the controller 8 by circuit. The controller 8 inputs the value for deciding the circuit attenuating amount at every circuit. Whenever the input trunk at the input side of a time division switch 3 is connected to the transmitter 4 at the output side, the value for deciding the attenuating amount of the corresponding circuit is simply inputted to the processors 7a and 7b.

摘要： PURPOSE:To secure a natural cell level over a wide line length by inputting an output of a detection means of a call current to a cell loss compensation means and controlling a call loss compensation amount in accordance with the call current value. CONSTITUTION:A sound signal, which arrives from a terminal device 1 and appears at both ends of a resistance 38, is amplified by an amplifier 312 of a call loss compensation circuit 31. On the other hand, a DC voltage in correspondence to a subscriber line length is outputted from a current detection circuit 30, and impressed to a base input of an FET310 through a current reducing resistance R5. When a line resistance value is small, a call current becomes larger, whereby the voltage impressed to the base input of the FET310 is large. Then a conduction resistance is small, and gains of the circuit 31 become small. Meanwhile, when the line resistance is large, gains of the circuit 31 become large, thereby compensating losses of a sound signal.
