Abstract: PURPOSE: To obtain intelligent network service such as credit communication service by adding a function part which processes a DTMF signal system capable of direct communication with a subscriber to a repeating exchange. CONSTITUTION: When digits from an exchange are a credit communication service call as an intelligent network service call, the origination number and origination class are gathered from the exchange and then an R2MFC transmitter receiver 4 is reset. Then a channel to the exchange is formed and an existing subscriber signal system (DTMF) is placed in operation to send out a guidance broadcast prompting secret number input from a guidance broadcast sending-out device 10. Then the device 10 and a DTMF reception device 6 are reset once a secret number is gathered to carry on the service. Consequently, the intelligent network service which should receive information from a subscribed during the service like the credit communication service can be provided.
