In FIG. 1, the higher-level device not shown is the interface section 1.
It is connected to the communication control unit 2 that performs transmission control via the communication control unit 2, and data is exchanged. The arithmetic processing section 3 is connected to the ink face section 1 and the communication control section 2, and controls the connection between the host device and the line. The communication control section 2 is connected to a modem or terminal device (not shown) via a line via line connection sections 4' and 5.6 that perform line control, and data is exchanged.

Here, the feature of the present invention is the communication amount detection section 7. That is, the start time and stop time are set by the timer 8 from the outside. A cutting signal from a timer 8 is connected to a detection circuit 9 to start and stop detection. The communication control section 2 is connected to the detection circuit 9, and the transmission control signal of each line detected from the detection circuit 9 is connected to the measurement circuit 10, and the usage time of each line is measured. The usage time of each line is connected from the measuring circuit 10 to the register 11 and accumulated.

The output signal of the timer 8 and the cumulative usage time of each line from the register 11 are connected to an arithmetic circuit 12, and the usage rate of each line within a certain period of time is calculated. The output signal of the arithmetic circuit 12 is connected to a display circuit 13, and the usage rate of each line is displayed externally.

The operation of the communication control device having such a configuration will be explained. In FIG. 1, a timer 8 is a timer whose start and stop times can be set by external input, that is, by manual setting or by a program, and the detection circuit 9 starts and stops detection based on this output signal. The detection circuit 9 is connected to the communication and control unit 2 and detects STX, which is the beginning of a data block, and EO, which indicates the end of data transmission.
A transmission control code such as T is detected and the output is sent to the measurement circuit 1.
Enter ゜. Thereby, the measuring circuit 10 measures the time that the line is used for communication, and stores the result in the register 11.

The register 11 has a function of accumulating the time measured by the measuring circuit 10 within the time set by the timer 8, and is generated from the stop time set by the timer 8 and sent via the detecting circuit 9 and the measuring circuit 10. The accumulated contents are cleared by the Kururi Cent signal. The arithmetic circuit 12 inputs the time for measuring the amount of communication from the timer 8 and the accumulated time used for communication on each line from the register 11, and calculates the amount of communication per unit time.

A display circuit 13 that displays the output of the arithmetic circuit 12 as a bar graph with a scale or as a numerical value on a display.

The traffic detection unit 7 described above is configured to be able to detect the traffic of a plurality of lines at the same time. Furthermore, although the case where there are three line connection units has been described, the same implementation is possible with three or more line connection units.

〔Effect of the invention〕

As explained above, the present invention has the excellent effect of being able to detect the traffic of each line and display it externally by adding a traffic detection unit to the communication processing device. Therefore, the operator can know the actual amount of communication, and there is an advantage that the communication processing device can construct an information device having a line configuration that provides optimal load distribution.
