Conventionally, as a signaling system for electronic exchange, there is a common line signaling system, as shown in FIG. 2, in which signals are sent and received through a dedicated data line separated from a speech line. This method allows you to obtain signals of many types of information, and allows signal transfer even during a call.
It has features such as faster signal transfer. In the figure, 1 shows a communication path, 2 is a telephone, 3 and 4 are trunks, 5 is a control section of the communication section 1 using a control signal 13, 18 is a signal processing section, and 11 and 12 are
2W telephone signal, 14 and 15 are voice signals, 19 and 20 are speech lines, and 21 is a control data line.

However, as mentioned above, since the signal line and the telephone line are separated, even if there is a failure in the telephone line, for example, the user will be billed. It has drawbacks such as being uneconomical for small bundles of communication lines where signal line failures have a large effect.

As explained above, the present invention is not a system in which control signals for each call line are collectively sent and received, but a method in which call signals and control signals are multiplexed on each call line by compressing the audio signal band. This makes it possible to send and receive multiple control signals. Signal transfer is possible even during a call. Signal transfer is as fast as 32kb/s. A failure in a call line is a failure only in that line, and can be transmitted to other lines. Does not cause any harm, does not require common lines other than the telephone line, and is economical even with a small number of telephone lines.
