Abstract

PURPOSE:To execute the telephone service efficiently, by connecting a B board and a private branch exchange through a remote control device by a leased circuit or a privately owned line and by controlling the private branch exchange of another region by the B board belonging to a separate region. CONSTITUTION:Private branch exchanges PBX0-PBXn are provided in region numbers #0-#n, and a group of B boards ATT0-ATTn connected to respective exchanges is installed in the region #0. When a call comes from a general pay station line network T to the exchange PBX1 installed in the region number #1, a central office truck COT1 detects the incoming and uses remote control devices A1 and B1 to report its information to the B board ATT1 through a leased circuit l1. Then, the server of the region number #1 confirms the indication of the incoming of the B board ATT1 and answers and transfers the trunk line to an extension of the region number #1. Thus, the private branch exchange in another region is controlled by the B board belonging to a separate region to execute the telephone service efficiently.
