Abstract

PURPOSE:To reduce the burden of a central controller, by providing a means storing numeric information and a means transmitting the stored information to the central controller for an instantaneous start trunk. CONSTITUTION:An extension telephone set 1 is connected to a main trunk via a main channel switch 2 and an instantaneous start trunk 3. When an incoming call is given from an opposing station, the trunk 3 informs the incoming call to a central controller and prepares for the reception of a dial pulse and gives the numeric information to the device 4 every time the numeric information is transmitted from the opposing station. The device 4 calls out the extension 1 according to this numeric information.
