Abstract

PURPOSE: To simplify and facilitate the adjusting work of a circuit constant by storing network control data at every channel area, and enabling the constant of a network control circuit to be automatically set.
CONSTITUTION: A CPU retrieves the network control data in a RAM based on an inputted channel area code, and automatically sets the circuit constant of a network control part 39 by outputting ON/OFF signals S1-S6 to photocouplers PC1-PC6 based on corresponding network control data. And the DC resistance of a DC loop formation circuit 42 is regulated by every country, and a DC resistance component goes to the synthetic resistance of a resistor R1 and the DC resistance of a transformer 44 by turning off the ON/OFF signal S1, and the DC resistance component goes to only the DC resistance of the transformer 44 by turning on it, which enables every country to be regulated by the difference of a resistance value. In such a way, it is possible to easily set the constant of the network circuit differently at every channel area with a simple operation, and to simplify and facilitate the adjusting work of the circuit constant.
