Abstract

PURPOSE:To smoothly perform calling and transmission by performing dial transmission in accordance with a telephone number transmitted from an originating subscriber side by means of off-hook and making the line between the originating side and incoming side serviceable by connecting the line between both sides. CONSTITUTION:Data input and instruction for transmission against a control processing section 2 are performed through a key pad 1 and each processing necessary for transmission is performed at the processing section 2. A line processing section 9 sets data to a transmittable state by connecting the originating and incoming sides with a public line by using as NCU 8 upon judging a call and causes the data transmission to be carried out. Upon completing the data transmission, the processing section 9 releases the line and terminates the transmission. Thereafter, the processing section 9 registers the telephone number of the calling station in a telephone number memory section 10 and, at the same time, causes a buzzer 12 to produce a ringing tone. When a receiver 11 is set to its off-hook state while the buzzer rings, the processing section 9 dials the telephone number registered in the memory section 10 and connects the originating side with the called side so as to establish a talking state.

．． It is composed of a receiver 11 and a buzzer 12. Note that 6 in the figure is an exchange.

The keypad 1 is used to input data (key presses) and give instructions for transmission to the control processing section 2. The processing section of the control processing section 2 performs various processes necessary for transmission, connects the public line 5 through the NCU 4, connects the receiving side through the public line 7 via the exchange 6 by dialing, and receives the ringing. This is done for the NCU3 on the side (connection ringing is NTT).

The line processing unit 9 determines that it has been called, and the NCU 3
is used to connect to the public line 7, the calling side and the receiving side are connected to enable data transmission, the control processing unit 2 transmits the call data to the line processing unit 9, and upon completion, the line is released. to end the transmission. Thereafter, the processing section of the line processing section 9 registers the telephone number of the calling station in the telephone number memory section 10, and the buzzer 12 generates a ring tone (1).
