APPARATUS FOR CONNECTING EXTENSION LINE NUMBERS IN KEYPHONE SYSTEM

摘要

PURPOSE: The apparatus for connecting extension line numbers in a keyphone system is provided to transmit a call request signal to a selected extension number by searching extension numbers registered in a main device of a private branch exchange through a user's telephone for call connection with a requested extension number, after connecting the dialing signal from the external. CONSTITUTION: A control part(110) stores user number information for extension telephones in a storage part(130) and generates a dialing signal to connect a call request signal transferred from external to an extension number selected by a selection part(150). A setup part(120) connected to a keyphone(100) sets up the user number information of extension telephones. The storage part(130) stores the user number information of extension telephones. A display part(140) displays user information in a form corresponding to user number information so that the selection part(150) can select the user number information of extension telephones stored in the storage part(130). The selection part(150) selects an extension phone number corresponding to the call request signal from the user number information of extension telephones stored in the storage part(130). A receiving part(160) receives the call request signal transmitted from the external.
