PURPOSE:To achieve a charging processing system in which a charging system can rationally be constituted as an adaptor, an electronic automatic private branch of exchange is not expensive for the addition, and the functions of the exchanger can hardly be entirely stopped at the production of failures. CONSTITUTION:Central processing devices CPU0, CPU1 and main storage devices MM0, MM1 which perform exchange and charging processings are independently provided functionwise to share the functions. The reception/transmission of information between both the processing units is made by a temporary storage device TM(TMB, TMF) which is directly connected to bus lines BUS0 and BUS1 tying the respective central processing unit and the main storage device and is accessible from the central processing units, and the amount of information exchange is kept minimum between the both via the temporary storage device, and the charging processing after the reception of the required information at the charging device from the electronic exchanger is made all at the charging device side. |
