Abstract

PURPOSE:To remove an illegal service request by providing a service supplying device with a code sending means and a collating means, providing a user device with a code returning means and sending a code from a code sending means through a set up and formed control information channel. CONSTITUTION:The service supplying device 10 receiving a service request from a user device 2 through a control information channel 4D, a digital exchange 6 and a control information channel 8D sends data channel setting information and the code from its code sending means 18 to the user device 2. The code is received by a code receiving means 12 and then returned to the device 10 through a data channel 4B, the exchange 6 and a data channel 8B. When the returned code coincides with the sent code or a previously determined collating code, service data are sent from a data sending means 22 through a formed data channel. When both the codes are not coincided with each other, a disconnection signal is sent to the exchange 6 through the channel 8B.
