Abstract
PURPOSE: To make the incoming call of a dialing system arrive at an optional telephone set by terminating the incoming call to an extension telephone set, which is located in a storage position to meet an extension designating signal, while referring to the table of a storage device.
CONSTITUTION: When an extension signal is transmitted from a station, a multifrequency signal analyzer 4 analyzes this signal and informs an information to a central control device 5. The device 5 refers to the table, in which the number of the extension designating signal, stored in the storage device 8, and the storage position of the extension telephone set are made to correspond to each other, and it finds out what extension telephone set the incoming call of the direct dialing should be terminated to. Then, it connects the extension telephone set in the storage position to a ringing device 7 through a terminal supervisory equipment 2, and rings a bell. When the extension telephone set is off-hooked, the device 5 disconnects the device 7, and builds up a channel through a dial-in line and a channel switch 6.
