Since this is an open matter, no full text was included.

1 is a module connection system diagram, FIG. 2 is a circuit diagram according to the present invention, and FIG. 3 is a concrete circuit diagram of the multiplexer portion 50 and the station modular jack portion 90 of FIG. 2 according to the present invention.

Claims (3)

In the system that can be used by connecting a general telephone and a key phone telephone, the trunk interface 10 is connected to the CO line (CO1-COM) to interface so that the voice and tone signals can be transmitted well by the control signal, and the program A central processing unit 20 for controlling the trunk interface 10 according to communication and generating a control signal according to communication; a central processing unit control circuit 60 for controlling the central processing unit 20; Receiving control signals and data from the processing unit 20, the network unit 40, which is composed of rows and columns even though paths necessary for operation of the trunk line, station, expansion port path and system are formed, and the expansion port connected to the expansion port. Door phone. Terminal, M0H... Expansion port driver 30 for driving drive signals such as; first and second subscriber line interface casings 70 and 80 for controlling n general telephones and key phone telephones; and the first and second subscriber line interface cards ( Interfacing each subscriber is selected by the station modular jack unit 90 and the data and control signals output from the central processing unit 20, which is connected to 70, 80 so that any of the general telephone and the key phone telephone can be connected to the module jack In the connection between the first and second subscriber line interface cards 70 and 80, and the network book 40, two pins are paired so that the n general telephone passes and the n keyphone telephone passes are selectively connected. An automatic hybrid system for a general telephone and a key telephone telephone, characterized in that the flexure unit 50 is configured. There is a method for controlling the port connection use of a general telephone or a key telephone telephone. In the first step and the first step, when the general conversion device or the key phone is not used, the count value is increased to count the number of connection ports of the module. And a third process of counting the number of ports in the second process and checking whether each service is completed at all ports of a general telephone or a key telephone telephone. Way. A method for handling interrupts using port connections of a general telephone or a key telephone telephone, comprising: a first step of relaying a corresponding register and signaling a corresponding port to check whether received data is invalid; A second step of checking whether the bit is in the first state and a second state if it is not invalid; and if the bit is not in the first and second states in the second step, the table of the jitter is cleared A third step of resetting and forming a path according to a general telephone or a telephone telephone; and checking the total number of ports by increasing the count value in the first and second states or from the third step. An automatic hybrid control method for both a general telephone and a key telephone telephone, characterized in that the fourth step. ※ Note: The disclosure is based on the initial application.
