Abstract
PURPOSE:To enable calling a desired terminal without hindrance from any other terminals by receiving a control signal generated in accordance with the depressing of an operational button on a connected communication terminal equipment by means of a reception means, and limiting an incoming call to a first terminal only to a second terminal by the reception means in which the control signal designates the first and the second terminals. CONSTITUTION:A central controller 2 supervises at all time a call request from respective extension interface 6, 7, 8, the time-out of an incoming call regulating timer 25, an input from a specific extension incoming call reserve button, etc. When a handset 18 connected to the controller 2 is hooked off, a corresponding interface detects this hooking-off and informs this to the controller 2 as the issuance of a call request. When subsequently a push-button 24 of an extension telephone set is depressed, a signal discrimination part 26 discriminates the signal so that the controller 2 recognizes a corresponding input telephone number and specifies an interface to be connected. Thereafter, status information is read out from a memory 4, and a call is enabled between the caller's telephone set and the called telephone set.
