Abstract

PURPOSE:To avoid a trouble when a charge is collected by providing a discrimination control part to a key telephone system, which can calculate the call charge of a line wire, print the result and output it, and refusing transmission with a transmission control part when the transmission is a charge non-calculable area. CONSTITUTION:A hand-set, which is not shown in the figure, to be included in a key input part 8 is hung up from a telephone set T and a line wire button of not-being used, whose idle condition is displayed by an LED, is pushed. Then, the line wire is supplemented and a dial transmission is executed. Thus, the information of an off-hook, line wire button selection and a dial signal are impressed to a control circuit 7 and the processed information are sent through a data transmitting and receiving circuit 6 to a data transmitting and receiving circuit 2 of a main device M. The circuit 2 adds the receiving information to a CPU3 and here the information are processed and transmitted to a discrimination control part 5, a dial signal sending circuit 1 and a call charge calculating circuit 4. In the discrimination control part 5, a dial number is received and discriminates whether an area is the calculable area of the calculating part 4 or not. When it is the calculable area, the charge is printed to a printer P.
