PURPOSE:To collect sufficient data such as old telephone number, call number classified by information guide, time and date by connecting a central processing unit to an automatic notice guide device via an interface circuit to collect and analyze information. CONSTITUTION:When a control circuit 52 sends accommodate location information from an exchange to a bus 58, a control circuit 54 accesses a telephone number storage device 57 and sends old telephone number, new telephone number and notice guide type information corresponding to the accommodated information to a bus 59. A control data bus supervisory section 61 in an interface circuit 6 supervises the transmission of the accommodated location information from the circuit 52 to the bus 58 and when the transmission is detected, the section 61 gives a command to an information read section 62 to steal the information from the bus 59. The read section 62 reads the old telephone number and the notice guide type information and sends them to the central processing unit 7, and the unit 7 uses to a collation means 71 to store the collected data sequentially in a storage device 8. In this case, when the means 71 stores the collected data in the device 8, the data arrived at a prescribed time interval is added with the time information and the result is stored. |
