Abstract

PURPOSE: To transfer the data of large capacity in a short time by providing a control system/calling system interface device between the control system data bus of an electronic exchange and a calling system time-dividing data bus.
CONSTITUTION: A control system/calling system interface device 6 is connected between a central control device 2 and a calling system time-dividing data bus 5. The control system/calling system interface device 6 fetches the data of the specified time slot of the calling system time-dividing data bus 5 and the data are sent to the central control device 2. Then, data from the central control device 2 are inserted to the specified time slot of the calling system time-dividing data bus 5. Accordingly, the data can be transmitted and received between the central control device 2 and the calling system time-dividing data bus 5. Thus, data transferring can be executed at a high speed with using the calling system time-dividing data bus.
