Abstract

PURPOSE:To realize a switching system for conventions which has a function of transferring the right of updating a screen by storing an incoming-terminal equipped switching device with an originating terminal device number and incoming terminal device numbers sent from an originating-terminal equipped switching device. CONSTITUTION:When terminal devices A, B and C equipped to mutually independent switchboards are connected, the connection code of originating terminal device A is sent from switchboard EXTA, equipped with the originating terminal device, to switchboards equipped with incoming terminal devices as well as a series of pieces of connection information on terminal devices. Switchboards EXTB and EXTC equipped with the incoming terminal devices analyze the received information to make sure they are ones equipped to them and, while connecting the terminals, store the number of the originating terminal device and numbers of those terminal devices. When the right of updating the screen is transferred, this memory information is used for information transmission address discrimination., etc.
