Abstract
PURPOSE:To increase the service without delaying the response to the main line caller, by avoiding the necessity of troubling the operator again in connecting a main line incoming call continuously two or more extension telephone sets, and reducing the burden to the operator. CONSTITUTION:A main line incoming call is fed to an attendant board ATT in a route 1 via a main line trunk CBWT to illuminate the incoming call dispaly lamp, and the operator responds to the main line incoming call by depressing the response key. After that, the operator depress the numeric button key for the number of extension telephone sets STA, A and B to be connected at second to store the number information to a main line trunk adaptor CBWTAU in route 2. Further, every time the trunk CBWT detects the ON-hook of the extension telephone sets A, B, the adaptor CBWTAU is started, and the information is fed to the sequential common control device MKR from the extension telephone set A or B in the number having the priority, and the trunk CBWT and the extension A or B are connected at the switch frams SW.
