Abstract
PURPOSE:To reduce the burden of an operator, by automatically connecting to an extension telephone set by directly dialing an extension number, in case when a line wire telephone is a pushphone telephone set. CONSTITUTION:When a call from a line wire telephone set TEL1 comes in, a primate branch exchange PBX, at first, connects the TEL1 to a talkie return trunk TKT. Subsequently, from the TKT, such a voice as ''Pushphone's caller! Please push an extension number.'', etc., is returned to the TEL1, and immediately the TEL1 is connected to a push register trunk PBRT. When the TEL1 is a pushphone telephone set and its extension number is pushed, the TEL1 is connected to an extension telephone set without an operator's work. On the other hand, in case when the TEL1 is a dial telephone set, a pushphone signal is not received even after a constant interval of time has passed, therefore, after the constant interval of time has passed, the TEL1 is connected to an attendant board.
