Abstract

PURPOSE:To prevent crosstalk between facsimile communication and telephone communication by identifying the kind of incoming information informed from a communication network receiving a call, applying facsimile communication in the case of facsimile information and calling the operator in the case of telephone voice information to bring the state into the communication state. CONSTITUTION:A network interface section 1 monitors the state of an ISDN circuit 2 at all times and when an incoming notice comes from the circuit 2, it is informed to a network control section 3. The network control section 3 analyzes what the incoming signal represents and when it is a telephone voice, it is informed to a speech control section 4 to call the operator and a speech section 5 uses for the communication. If it is identified that the call is a call from a facsimile equipment, it is informed to a transmission control section 6 and a printer section 7 records image information. Thus, the speech control section 4 is not started in the case of facsimile call and no ring tone is caused.

Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) (Industrial Application Field) The present invention relates to a facsimile device connected to an ISDN line.

(Prior art) Conventionally, the line to which a facsimile machine is connected is DD.
It was limited to X lines or public telephone lines.

In the former case, only facsimile information can be passed, and voice information cannot be passed.

The latter case has the advantage of allowing both telephone and facsimile information to pass through.

Furthermore, SDN lines, which are scheduled to be realized in the near future, will also be capable of transmitting both telephone and facsimile information.

(Problem to be Solved by the Invention) However, conventional facsimile machines connected to public telephone lines do not have a signal to identify the type of information received, so they are connected to telephones even though they are facsimile machines. There have been problems with incorrect connections, such as being connected to a facsimile machine even though it is a telephone.

This invention was made in view of the above problems,
Its purpose is to
To automatically perform facsimile communication if the received information is facsimile information, or to automatically perform voice communication if the received information is telephone information, in a facsimile device connected to an SDN line.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides at least an IS
A network interface unit that realizes connection to a DN line, a transmission control unit that sends and receives facsimile information while performing encoding and decoding processing, a printer unit that outputs decoded image information, and a telephone unit that executes telephone operations. An incoming call information identifying means, located in a facsimile machine having a call control unit and a network control unit for transmitting/receiving the facsimile information and controlling call procedures related to telephone calls, identifies the type of incoming call information notified from the network at the time of incoming call. and, if the incoming call information identified by the incoming call information identifying means is facsimile information, facsimile incoming notification means notifies the transmission control unit of the incoming facsimile, and the incoming call information identified by the incoming call information identifying means In the case of a telephone, the network control section is further provided with a telephone incoming notification means for notifying the telephone call control section of the incoming telephone call.

(Function) According to such a configuration, the type of incoming information notified from the network at the time of incoming call is identified, and if the identified incoming information is facsimile information, the transmission control unit is notified that the received facsimile is being received. In the case of a phone call, the call controller is notified of the incoming call.
When receiving facsimile information, it is possible to reliably connect to the facsimile communication, and when receiving telephone calls, it is possible to reliably connect to the telephone.

(Embodiment) FIG. 1 is a block diagram showing an embodiment of a facsimile apparatus according to the present invention.

In the figure, a network interface section 1 is a section that controls the interface with an ISDN line 2.

The network control unit 3 controls call procedures related to facsimile 'ifl@' and telephone calls.

This network control unit 3 includes a call information identifying means 3a for identifying the type of call information notified from the network when a call arrives, and if the call information identified by the call information identifying means 3a is facsimile information, facsimile incoming notification means 3b for notifying the transmission control unit 6 of incoming facsimile calls;
When the incoming call information identified by the incoming call information identifying means 3a is a telephone call, an incoming call notification means 3C is provided for notifying the call control section 4 of the incoming call.

The call control unit 4 controls voice communications such as telephone calls.

The call els 5 does not indicate a handset or the like for making a call.

The transmission control section 6 executes facsimile procedures such as G4/G3 procedures.

The printer section 7 converts the received image information and the like into a hard copy.

Next, the general operation of a facsimile machine having such a configuration will be explained.

If you receive a facsimile call from ISDN number 1!2,
The network interface section 1 detects this and notifies the network control section 3 that there is an incoming call.

1J, the network control unit 3 identifies that the incoming information is facsimile information based on the notification from the SDN line, notifies the transmission control unit 6 of the incoming 71 facsimile call, and Execute call procedures.

Thereafter, the transmission control unit 6 executes a facsimile procedure, and in the case of facsimile reception, decodes the facsimile information into image information and transfers it to the printer unit 7.

The transferred image information is converted into a hard copy by the printer section 7.

Further, when there is an incoming voice (telephone) call from the ISDN line B2, the network interface section 1 detects this and notifies the network control section 3 of the incoming call.

The network control unit 3 identifies that the incoming call information is a telephone call based on the notification from the ISDN line, notifies the call control unit 4 of the incoming call, and executes the call procedure via the network interface unit 1.

Thereafter, the call control unit 4 calls the operator using a ring tone or the like.

The operator makes a call using the call unit 5, such as a handset.

Next, FIG. 2 is a flowchart showing a main part of the operation of the apparatus of this embodiment, and the operation of the apparatus of this embodiment will be systematically explained below with reference to this flowchart.

When starting this operation, the network interface section 1 constantly monitors the state of the tSON circuit a2, and this 18D
When there is an incoming notification from the N line 2, this is notified to the network control unit 3.

As a result, the network control unit 3 analyzes a signal indicating the type of incoming call information from the ISDN line 2, and if the information is voice (telephone) (step 201), a signal to that effect is sent to the call control unit 3. The operator is notified by a ring tone, etc., and a call is made using the communication unit 5 (step 207).
.

Further, when the network control section 3 identifies that the information is an incoming call from a G3 facsimile (step 201), it notifies the transmission control section 6 of this fact.

Then, the transmission control section 6 executes the G3 facsimile procedure, and if the status of the printer section 7 is ready (step 204), the facsimile information is decoded and the image information is recorded by the printer section 7. (Step 2o6).

If the state of the printer unit 7 is such that a failure has occurred such as an operation failure (step 204), the incoming call is rejected and a disconnection procedure is executed (step 205).

Furthermore, if the type of incoming information from the ISDN line 2 is not specified (step 201), the network control unit 3
If automatic reception is set (step 202>), the transmission control unit 6 is notified of this, and the transmission control unit 6 receives the G4
If there is a response from the other party and the printer unit 7 is in an operable state (step 203), the facsimile information is decoded and recorded by the printer unit 7.

If there is no response from the other party or if a failure has occurred in the printer section 7 (step 203), the call control section 4
is activated, and prompts the operator to respond with a ring tone or the like (step 207).

Also, if automatic reception is not set (step 2)
02), the call control unit 4 is activated, and the operator is prompted to respond by using a ring tone or the like (step 207).

In this way, when it is determined that the call is an incoming facsimile call, the call control unit 4 is not activated and no ring tone is produced.

Furthermore, if it is determined that the call is a voice call, the transmission control unit 6 will not be activated and the facsimile procedure will not be executed.

〔Effect of the invention〕

As is clear from the above description, according to the present invention,
If the facsimile information is identified, it immediately starts executing the facsimile procedure and performs facsimile communication, and also receives voice information (telephone information). ), the operator is immediately called by a ringing tone or the like, so that a telephone conversation can be made.

Therefore, even though it is a facsimile reception, when the telephone is connected and the ring tone sounds and the operator responds, you may hear a signal tone peculiar to a facsimile, or even though it is an incoming telephone call, the facsimile There is no longer a need for the other party to hear a signal tone unique to a facsimile.
