Abstract
PURPOSE:To automatically switch a call from a telephone set to a telephone set and a call from a terminal equipment to a terminal equipment by receiving an incoming call without ringing for a prescribed time on the callee's side, and detecting the presence/absence of a terminal calling signal during said prescribed time. CONSTITUTION:When a push-button 3 is depressed, a DC loop including a controller 18 is formed, a calling tone transmitter 14 is driven under a command from the controller 18, and a telephone calling tone is returned to the caller's side. In case the caller's side is a facsimile equipment, a facsimile calling signal is transmitted, hence the calling signal is detected by a calling signal detector 13 whose output is impressed the controller 18. The presence/absence of the facsimile calling signal is detected during this prescribed time, during which time, a telephone set 6 is does not generate ringing tone. Further, under an instruction from the controller 18, the operation of the transmitter 14 is stopped, relay contacting points 10, 11 are operated and switched, and at the same time, the facsimile equipment 7 is activated in order to receive a message.
