Abstract
PURPOSE:To automatically control the sound volume of ringing in a slave station device by comparing, in a dispersed master station device, a collected noise with a set noise and outputting a sound volume information signal corresponding to the result of said comparison together with a ringing signal. CONSTITUTION:The dispersed master station device 3 which respond a call coming through a private branch exchange, senses and collects environmental noise by a sound volume level detection means 12, and its control part 11 compares a collected noise level with a set noise level and outputs a sound volume information signal for sound volume setting, and this signal is transmitted together with a ringing signal. These transmitted information are received by the slave station device 41, and the sound volume of ringing from a buzzer 44 is automatically controlled in a suitable value by a sound volume setting circuit 46 corresponding the sound volume information signal.
