Abstract

PURPOSE:To avoid an increase of traffic following a connection change, by constituting so that a part or the whole of a channel used by a trunk whose connection change is not executed yet can be used by a trunk whose connection change has been executed. CONSTITUTION:In case when there has been an incoming call through a board to a subscriber TELA through a main wire trunk COT, a pulse 4 is set, and when an operator performs a selective operation of the TELA, a connection change is executed in accordance with the following procedures and a call is set. (1): A controlling circuit 6 selects an idle path from a path idle/busy storage part 8, sets a path 1 to a control part, and sends a call signal to the TELA. (2): The path 1 is stored in a reserved path storage part 9. (3): Information of the path 1 is fetched and is used for selecting a connection setting path 2. (4): The path 2 is stored in the storage part 9. (5): In case of selecting a path 3 required for a split call, too, information of the path 1 or 2 stored in the storage part 9 is used. Said operations are executed by a program of a program storage part 7.
