[Problems to be Solved by the Invention] However, in such conventional line switching devices, manufacturing drawings must be prepared for each communication control device, and extra connection cables are required. There were drawbacks that hindered the development of The present invention solves the above-mentioned drawbacks, and provides a line switching device that can unify manufacturing drawings of communication control devices, reduce the number of device-connecting cables, thereby making the device smaller and easier to maintain. With the goal. [Means for Solving the Problems] The present invention is a line switching device provided in each of a plurality of communication control devices connected by a line, which selects a communication control unit and a communication control unit of the other party. In the line switching device, the line switching unit includes a line adapter unit that connects to the line group of the own communication control unit, and a line switching unit that provides a selection signal to the line adapter unit, the line switching unit connecting the line group of the other party communication control unit A register that holds a number, a switch that sets the number of the own communication control section, and a signal that selects a predetermined cable position to connect the communication control section of the other party based on the output of this switch and the output of the above register. The present invention is characterized by comprising a conversion circuit that outputs the selection signal as described above. [Operation] According to the present invention, a register holds the number of the other party's communication control unit, and a switch sets the number of its own communication control unit. Based on the number of the communication control unit of the other party and the number of the own communication control unit, a selection signal for selecting a predetermined cable position to connect the communication control unit of the other party is output from the conversion circuit to the line adapter unit. By connecting the communication control device to the own line group, it is possible to standardize the manufacturing drawings of the communication control device, reduce the number of device connection cables, thereby making the device smaller and easier to maintain. [Example] An example of the present invention will be described with reference to the drawings.

ADR is a destination communication control unit address register that holds the destination communication control device number. SW is a communication control unit address switch that holds the own communication control device number and allows the number to be changed. P-ROM
is the output address of the destination communication control unit address register ADR and the own communication control unit address switch.
This conversion circuit has a conversion bit pattern for selecting one communication control device among n+1 communication control devices CCP 0 to CCP o according to the output address of the SW. R 1 and R 2 are dividing resistors for pull-up resistors for supplying a "1" potential as the address input of the conversion circuit P-ROM when the address switch SW of the own communication control section is "off". V is the pull-up power supply and E is the ground. The output of the address switch SW of the own communication control unit sets the own communication control device number by setting the potential to "0" when it is "on" or to "1" when it is "off". SD and RD are a transmitting circuit and a receiving circuit that connect the communication control unit CCU and the line group LA.
LAB is a line adapter common part with transmit circuits SD and RD. The operation of the circuit switching device having such a configuration will be explained.

The transmission line SD and reception circuit RD with CCU o are selected, and the circuit group LA 0 of the communication control device CCP 0 and the communication control unit CCU o of the communication control device CCP o are connected. The table shows the conversion pattern of the conversion circuit of the line switching device of the present invention, and shows the case where there are five communication control devices CCP. In the table, the conversion circuit input consists of the own communication control unit number bit “3” and the connected communication control unit number bit “3”, and the conversion circuit P-
This becomes the ROM address bit. The conversion circuit output is a bit pattern in the conversion circuit P-ROM selected by the above address, and the bit pattern is configured so that one of the five communication control devices is selected. In this embodiment, the line adapter common part LAB at the bit position corresponding to the "1" potential is selected, and the selected line adapter common part LAB

(The communication control device number and the communication control unit number are the same.)
When the destination communication control device number "0" is specified in the line group LA, the conversion circuit output becomes "01000" and the line adapter common section LAB 1 is selected. This line adapter common section LAB 1 is connected to the communication control device CCP 0 (communication control section
CCU 0 ).
