Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a conference telephone system.
This invention relates to a communication network control system including a control device.

(Description of the Prior Art) In the conventional conference telephone system, the conference telephone activation circuit requires manual operations, including turning on the power, at all times or when starting the conference call, to enable the conference call. The control station side connects the call line regardless of the status of the conference call station, even if there is a call line failure and a conference call is not possible. For this reason, the input/output terminals of the audio signal mixing/distributing circuit may become short-circuited (communication lines 2 and 1 are open), and the terminals and interference may be in a mismatched state. Reflections may affect other iIn channels, causing inconveniences such as noise and debris.Also, when a predetermined number of conference participants gather at the left telephone station, However, because conference calls remain enabled for long periods of time, there is a problem in terms of management, which is incompetent and uneconomical.

[Purpose of the invention]

In order to solve these problems, the present invention provides a remote conference telephone station with a function for controlling volume, a function for pre-checking, and a reporting communication means when controlling the connection of the telephone line at the IIYI fffll station. The purpose is to provide an efficient and economical conference telephone system.

(Summary of the Invention) The present invention provides a plurality of conference telephone stations including a conference call circuit for performing conference calls using microphones and speakers, connection control of call lines of the conference telephone stations, and mixing and distribution of audio signals. In a conference telephone system comprising a network control station including a connection control circuit, the network control station includes a connection command operation section, an activation signal sending circuit,
The conference telephone station is equipped with a response signal receiving circuit and an automatic dial/message transmitting circuit.
The present invention is characterized in that it includes a J signal receiving circuit, a conference call starting circuit, a display, a response signal receiving circuit, and a ready switch means (6ii).

[Explanation based on examples]

Next, embodiments of the present invention will be explained with reference to the drawings.

Power is supplied to the circuit I2, and the activation signal sent to the communication lines 3r, 2 is received and detected by the activation signal receiving circuit 12.

When the signal 1 is detected, the display 17 lights up.

Further, by detecting and outputting this activation signal, the first switch section IG-8 and the second switch section 16-b of the conference call activation circuit 16 are operated, and the conference call circuit 11 is connected to the communication line and the power is supplied. The electric current 141 (+() is supplied to the circuit 14 to enable a conference call using a microponse and a speaker.

At the same time, the response signal receiving circuit 13 is transmitted from the start signal receiving circuit 12.
and sends a response signal to the communication line 8.

The response signal sent to the communication line 8 is received and detected by the response signal receiving circuit 5 of the station 1111 on the network side. This is the connection command made by iM n1:3 and i51 is selected and j!
It is checked whether or not it is being sent to the 0-stuffed line, and if they match 2, the connection control circuit +1'32 is operated; g-u', and the corresponding iIn talk line is connected. Also, the start signal receiving circuit 4

Therefore, neither the display 17 nor the conference call circuit (the terminal 16 is in operation) nor the response signal from the response signal transmitting circuit 13 are transmitted. Therefore, the network control station 1 (7) response signal receiving circuit 5 sends the activation signal! 734, the activation signal is sent i,%2', and the response signal is not received within a certain period of time. Connection control for the corresponding 1m talk line is not performed. At this time, the automatic dialing/me/semi/sending circuit C is activated, and the dial number corresponding to the call line for which the call is not received is sent to the connection command operation unit 3. The system automatically dials the line 7, calls the corresponding conference telephone station 10, sends out a voice message 7, and instructs the conference call station 10 to promptly prepare for the event.

After this, when the ready switch step 15 is turned on and activated, power is supplied to the start signal receiving circuit 12 from the power supply circuit 14, and the reception detection operation of the start signal is performed, and the above-mentioned three start operations are performed. and j! ] The communication line connection operation is performed.

The ready switch means 15 is configured to control the power supply to the response signal receiving circuit 12 via the power supply circuit 14, so if you forget to turn on the power to the JN telephone station 10, the above-mentioned :u Q'j! ＋ 'nJ
