The control part 4 gives the instruction to stop the transmitting sound generator 11, gives the instruction to connect a line connector 6B to a line connector instructing part 8, and gives the instruction to disconnect a line connector 12 and to connect a line connector 13 to the line signal synthetic editing mechanism.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a teleconference device, a teleconference@device having the function of simultaneous conversation by two or more people at the same time.

(Prior art) In general, a representative telephone is used to switch lines when multiple telephone lines are used with a single telephone number.
Although it is possible to arbitrarily change the connection between telephone terminals, it is only possible to have a conversation between two parties: the person making the call and the person being connected.

[Problem to be solved by the invention]

In conventional representative telephones, there is only one line connected to one telephone terminal, and calls can only be made between two parties at the same time, making it impossible for many people to make calls at the same time.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned drawbacks and to provide a telephone conference device that allows a large number of people to talk at the same time.

[Means to solve the problem]

The telephone conference device of the present invention has a line signal synthesis/editing mechanism, a control interface unit, a tone generator, a line connection device, and a line signal synthesis/editing mechanism for line signal synthesis/distribution. It consists of a device and a line connector.

〔Example〕

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

FIG. 1 is a system configuration diagram of an embodiment of the present invention. In FIG. 1, 1 is a telephone conference S device.

In this example, the number of people using the telephone conference IK device is 2 people with 3 telephone lines,
2B, 2c12 Subscribe as a representative phone using a single phone number. In a normal representative telephone, a subscriber prepares a plurality of telephone terminals, but in this embodiment, one telephone terminal (3) is prepared. The 4H control unit is in charge of the processing of the telephone conference equipment R1, and 5 is a line signal synthesis/editing mechanism in which line switching and line signal synthesis are actually performed. 6. 6A, 6B, and 6C are line connectors, and 7 is an interface unit that monitors the usage status of the three telephone lines. 8 is a line connector instruction section, 9 is an interface section for sending instruction pulses sent from the telephone terminal SONG 3 to the control section 4, and 10.1OA, 10B, 10Ca3 (7) Telephone m terminal to IE talk nl! This is a line signal synthesizer/distributor that combines and edits the audio signals from A, B, and C.

First, suppose that a call is received on telephone line A when all the telephone lines are free and unused.

Then, the interface section 7 recognizes that a call has been made to the telephone line A, and notifies the control section 4 of this information. At this time, the telephone line is connected to the control section 4, and the control section 4 instructs the dial tone generator 11 for ringing the telephone terminal 3. 1! When the caller Song 3 picks up the handset, the information is notified to the control section 4 via the interface section 9, and the control section 4 performs the following processing.

Instructs the dial tone generator 11 to stop generating the ringing tone, connects the line connector 6, instructs the line connector instruction section 8 to connect the line connector 6At, and then connects the line connector 12t. The line signal synthesis and editing mechanism 5 is instructed to do so. Then, he picks up the receiver and sends a message to the two people on the phone line that the phone line is connected via the Inter7 Ace section. A conversation with the person begins. At this time, the four-wire signal flow is at the MI connector 6.6A. 12 and line signal combiner/distributor 10, IOA? It will be mediated by

Next, go to the line connection status in the above case.
Suppose that 2B receives a call. The line status check unit 7 recognizes that a call has been made to the telephone line 2B,
When the control section 4 is notified and the telephone line 2B is connected to the control section 4, the control section 4 instructs the dial tone generator 1l to generate a pulse tone on the receiver of the telephone terminal SONG 3. Then, the person who is talking on the telephone terminal SONG 3 recognizes that there is another call and presses the hook button on the telephone terminal SONG 3, and the information on the hook is sent to the control section 4 via the interface section 9. Here, the control unit 4 issues an instruction to stop the beep generator 11,
An instruction to connect the line connector 6B is issued to the line connector instruction section 8, and an instruction is issued to the line signal synthesis/editing mechanism to disconnect the line connector 12 and connect the line connector 13.

In this state, the person who made the call on telephone line *2A is placed on hold, and the person on telephone terminal Song 3 starts talking to the person who called on telephone line 2B. At this time, the direction signal flow Fi passes through the line connectors 6, 68.13 and the line signal combining/distributing unit 10.10B't.

Next, in order to simultaneously start a conversation between the person at the telephone terminal 3 and the people on the telephone line 2A and il line 2B, the following process is performed.

Information caused by pressing the hook on the telephone terminal 3 is sent to the control section 4 via the interface section 9, and the control section 4 sends the information to the line signal synthesis and editing mechanism 5 to the line connectors 12, 16't! Instruct the user to continue. With the above steps, a simultaneous conversation between three parties is started.

Next, from this state, use the telephone line 2C to connect the telephone terminal 3.
A fee will be charged to explain the process when making an external phone call.

When the information from the 3T terminal is sent to the control section 4 via the interface section 9, the control section 4 disconnects the line connectors 12 and 13 to the line signal synthesis and editing mechanism 5, and (
Self) Issue an instruction to connect the line connector 15. At this time, the four-wire connector 16 is in the connected state, so the telephone line M2A and the telephone line i
A call is in progress between fM2BL7). Next, the calling telephone number information is sent from the telephone terminal SONG 3 to the control unit 4 via the interface 9t, and from the control unit 4 to the telephone line 2C via the line status check unit 7! A call number will be sent. When there is a response from the destination, the information is sent to the control unit 4 via the line status check unit 7, and the control unit 4 connects the line connector 60 and sends the information to the line signal synthesis and editing mechanism 5. Instructs to connect the line connector 15.

With the above steps, a conversation between the person on the phone end Song 3 and the person on the phone line 2C is started.

Next, the control unit 4t-j: [According to the instructions from the storyboard Song 3, the circuit connection unit 12, 13, 14, 17
By issuing an instruction to connect, a simultaneous conversation between a total of four people, the person on telephone terminal 3 and those on telephone lines 2A, 2B, and 2C, starts. In this manner, the control unit 4 changes the line connectors inside the line signal synthesis/editing mechanism 5 in response to instructions from the telephone terminal 3, thereby making it possible to conduct a variety of simultaneous calls with multiple people. [Effects of the Invention] As explained above, the present invention makes it possible to have a conversation with multiple people at the same time, without considering the other party, by using the simultaneous conversation function with two or more people. It also has the effect of allowing you to have a conversation with each other.
