PURPOSE:To monitor the data on the internal data bus of an exchange and to display the data on the screen of a general-purpose terminal. CONSTITUTION:A bus interface 21 which decides the interface function set to an internal bus 101 and an information error sends the error deciding result and the bus data to an information editing means 23. The means 23 edits the transmitting destination address of the bus data, the data information, the error deciding result, the error occurring time, etc., and sends these editing results to an accumulating memory 25. A time setting means 24 sends the error occurring time to the means 23. A general-purpose terminal 30 is able to display the contents of the memory 25 on a screen through a general purpose interface. An exchange bus monitor circuit 20 of such a constitution is set into an exchange so that the faults can be effectively detected.
