Abstract

PURPOSE:To share one circuit with a telephone set and a facsimile equipment by detecting an incoming call from the network exclusive for facsimile communication and connecting the circuit and the facsimile equipment. CONSTITUTION:When a 16Hz incoming signal comes from a subscriber network via a line 1, a 16Hz detection circuit 3 detects an incoming signal. A control section 8 receiving the detection signal controls a calling signal 6 and a switch circuit 5 to connect the line 1 to an extension 21 connecting to a telephone set 10. On the other hand, a 1300Hz incoming signal comes from the network exclusive for facsimile communication via the line 1, then the 1300Hz detection circuit 4 detects the incoming signal. A control section 8n receiving the detection signal controls a call signal generating circuit 7 and the switching circuit 5 to connect the circuit 1 to an extension 2n connecting to a facsimile equipment 11. Thus, one circuit is shared with the telephone set and the facsimile equipment.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a telephone system such as a residential electronic switchboard or a key telephone device.

(Prior Art) In recent years, services using networks dedicated to facsimile communication have been launched. The incoming signal transmitted through this network is 13
00)-1z, which is different from the 16Hz incoming signal conventionally used in subscriber networks. However, the network dedicated to facsimile communication and the subscriber network are configured so that terminals are connected through the same line, and telephones and facsimile devices are connected through an in-home electronic switchboard, etc. This becomes a problem if

In conventional home electronic exchanges, the facsimile machine is placed in automatic call receiving mode, a line from one subscriber's network is dedicated to the facsimile machine, connected to the central office trunk, and when an incoming call is received, the direct inline function is used to , the line of the subscriber network and the facsimile machine are connected.

However, when connecting a facsimile machine to a line on a network dedicated to facsimile communication, conventional electronic home exchanges do not have the ability to detect incoming signals at 1300 Hz, so the line must be connected to the electronic home exchange. without intervening,
It was designed to connect directly to a facsimile machine. For this reason, one line can be used to receive both telephone call services from the subscriber network and services from a dedicated facsimile communication network, and the one line is shared by many telephones and facsimile machines. I couldn't.

(Problems to be Solved by the Invention) As described above, the conventional telephone system does not have a function to detect an incoming signal sent from a network dedicated to facsimile communication, and the network dedicated to facsimile communication and the subscriber network The line connected to the fax machine cannot be shared between a telephone and a facsimile machine, and the line cannot be used effectively.

The present invention was made in view of the above-mentioned drawbacks of the conventional telephone system, and its purpose is to provide a line connecting a network dedicated to facsimile communication and a subscriber network that allows communication by telephone or facsimile equipment. To provide a telephone system that can be shared by a telephone and a facsimile machine.

[Structure of the Invention (Means for Solving Problems)] In the present invention, different incoming calls are received from a first network capable of communication using a telephone or a hook-and-sink device and a second network dedicated to facsimile communication. A telephone system in which a signal arrives via one line includes a facsimile machine, an incoming signal detecting means for detecting an incoming signal sent from the second network, and after the incoming signal detecting means detects the incoming signal. , and a line connecting means for connecting the line and the facsimile machine to form a telephone system.

(Function) According to the above configuration, since the incoming call from the network dedicated to facsimile communication is detected and the line and the facsimile device are connected, it is possible to accurately sort out the incoming call from the network.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the main parts of a residential electronic exchange 9 which is an embodiment of the present invention. 1 indicates a line. Line 1 is usually provided with multiple lines, but here, typically one line is provided.
Only the line is shown. Line 1 is connected to the subscriber network and a network dedicated to facsimile communication, and line 1 also contains an incoming bell signal (18H) sent from the subscriber network.
7), a 1300 Hz detection circuit 4 that detects a 1300 Hz incoming signal sent from a network dedicated to facsimile communication, and a switch circuit 5 are connected. 21 to 2o indicate extensions. extension 2
1 to 2o can be connected to either a telephone or a facsimile machine, but here an example is shown in which the telephone 10 is connected to extension 21 and the facsimile machine 11 is connected to extension 2°. There is. Each of the extensions 21 to 2n includes a ringing signal generation circuit 6 that generates a ringing signal corresponding to an incoming bell signal, a ringing signal generating circuit 7 that generates a ringing signal corresponding to an incoming signal of 1300 Hz, and a switch circuit 5. or connected. 8 indicates a control unit, and this control unit 8 is composed of a microcomputer, = 5
- 1B) -1z detection circuit 3. Receives the detection signal from the 1300 Hz detection circuit 4, controls the calling signal generation circuit 6.7,
The switch circuit 5 is controlled as follows.

When a 16H2 incoming signal arrives from the subscriber network via line 1, 16H2 detection circuit 3 detects the incoming signal and sends a detection signal to control section 8. Upon receiving the detection signal, the control unit 8 controls the calling signal generation circuit 6 connected to a predetermined extension line to generate a calling signal corresponding to the 16H2 incoming call signal. Here, it is assumed that the calling signal generation circuit 6 connected to the extension 21 is controlled.
The calling signal reaches the telephone 10 and the bell rings. Therefore, when the telephone 10 responds, an off-hook signal is detected by means not shown, and the off-hook status is notified to the control unit 8. Thereby, the control unit 8 controls the switch circuit 5 and connects the line 1 and the extension 21.

On the other hand, from the network dedicated to facsimile communication via line 1,
When a 300 Hz incoming signal arrives, the 1300 Hz detection circuit 4 detects the incoming signal and sends a detection signal to the control section 8. Upon receiving this detection signal, the control unit 8 controls the calling signal generation circuit 7 connected to the extension to which the facsimile machine is connected (in this embodiment, the extension 2n to which the facsimile machine 11 is connected). A calling signal corresponding to the incoming signal of 1300H2 is generated. Then, the calling signal reaches the facsimile machine 11 via the extension 2n. The facsimile machine 11 receives the call without ringing, but
The facsimile machine 11 is in automatic call receiving mode,
When a response is received, response detection is performed by means not shown, similar to off-footer detection in a telephone, and the response is notified to the control unit 8. Thereby, the control unit 8 controls the switch circuit 5 to connect the line 1 and the extension line 2n.

In this way, according to this embodiment, when a call is received from the subscriber network via one line 1, the call can be received by the telephone, and when a call is received from a network dedicated to facsimile communication, the call can be received by the telephone. Sometimes, calls can be received by the facsimile machine, making effective use of the line. In addition, extension 21-2
．． Therefore, when acquiring a subscriber network or a network dedicated to facsimile communication, you can perform operations to acquire the central office line (for example, operate Dial rOJ) and then send the required dial number as before. good.

Further, in this embodiment, a ringing signal is generated, but the ringing signal generation circuits 6 and 7 are not provided, and after detecting an incoming signal, the switch circuit 5 is controlled to send the incoming signal to the corresponding extension. You may also send it directly.

[Effects of the Invention] As explained above, according to this embodiment, different incoming signals arrive from a network capable of communication by telephone or facsimile device and a network exclusively for facsimile communication via one line. In this case, after detecting an incoming signal from the latter network, it is guaranteed that the above line and the facsimile machine will be connected, so the above one line can be shared between the telephone and the facsimile machine, making effective use of the line. can be achieved.
