Abstract

PURPOSE:To display the identification of a speaker on the display of a data terminal by sending a data signal containing a voice level and a channel number to all data output channels. CONSTITUTION:When a voice is inputted to voice input channels 110, 111 and 112, voice level detecting circuits 310, 311 and 312 detect respective voice levels. Signal generating circuits 320, 321 and 322 generate data signals according to respective voice levels and channel numbers. The generated data signals are sent to all data output channels 220, 221 and 222. consequently, on the display of the data terminal connected to the data output channels 220, 221 and 222, the identification display of the speaker to be voice-inputted to the voice input channel 110 is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to conference trunks in automatic private branch exchanges.

[Conventional technology]

Conventionally, conference trunks of this type have not included the ability to send channel identification signals to data circuits.

[Problem to be solved by the invention]

In the conventional conference trunk mentioned above, the channel identification signal is not sent to the data line, so in a conference system that uses voice and data, it may not be possible to determine who is speaking, which may prevent the conference from proceeding smoothly. There is a drawback that there is.

[Means to solve the problem]

The conference trunk of the present invention is used in a conference trunk of an automatic private branch exchange handling voice and data having a plurality of data input channels each corresponding to a plurality of voice input channels and a plurality of data output channels respectively corresponding to a plurality of voice output channels. , comprising an audio level detection circuit that detects the input audio level on each of the audio input channels, and a signal generation circuit that sends a different channel identification signal for each of the audio input channels to the plurality of data output channels. do. [Example] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a circuit block diagram showing an embodiment of the present invention. In FIG. 1, 100 is an audio conference trunk circuit having three channels, 200 is a data conference trunk circuit having three channels, 110, 111, 112 is an audio input channel; 120, 121, and 122 are audio output channels corresponding to audio input channels 110, 111, and 112, respectively; 210, 211, and 212 are data input channels; and 220, 221, and 222 are data input channels, respectively. This is a data output channel. Further, 310, 311, and 312 are audio level detection circuits that detect the audio levels on the audio input channels 110, 111, and 112, respectively, and 320, 321, and 322 are signal generation circuits that correspond to the audio level detection circuits 310, 311, and 312, respectively. It is.

Next, the operation of this embodiment will be explained.

When audio is input to the audio input channels 110, 111 and 112, the audio level detection circuits 310, 311, 31
2 detects each audio level. Signal generation circuit 3
20, 321, and 322 generate data signals corresponding to each audio level and channel number. The generated data signals are sent to all data output channels 220, 221, 222.
sent to. That is, the audio signal input to the audio input channel 110 is sent to the audio output channels 121 and 122 by the function of the audio conference trunk circuit 100, but at the same time, the audio level is detected by the audio level detection circuit 310 and the signal is generated. A data signal containing this audio level and channel number is generated by circuit 320 and output to all data output channels 220,
221.222.

Therefore, the display of the data terminal connected to the data output channels 220, 221, 222 displays the identification of the speaker who input the voice to the voice input channel 110.

〔Effect of the invention〕

As explained above, the present invention displays the identity of the speaker on the display of the data terminal in a conference using data and audio by sending a data signal including the audio level and channel number to all data output channels. This has the effect of allowing the meeting to proceed smoothly.
