PURPOSE:To accurately add the subjective data by the hardware processing without using the software processing by adding the count value to the transmission/reception data on a communication equipment and storing these count value and data in a memory. CONSTITUTION:When the operation of a communication monitor device 3 is started, a data detecting circuit 4 starts input of the data flowing on a transmission line 2. At the same time, a counter circuit 5 starts its counting operation and the data transmitted and received between both communication terminals 1 are inputted to the circuit 4 included in the device 3. The circuit 4 detects a single frame of data and also outputs the transmission/reception data after dividing them in each frame. Meanwhile the circuit 5 outputs its count value independently or synchronously with the clock of the transmission/reception data. Then the transmission/reception data and the count value are inputted to a mixer 6. The mixer 6 adds the count value to the data of a single frame and outputs them. Therefore the data on a single frame including the count value are stored in a memory 7 in the order of data. |
