Abstract

PURPOSE:To simplify an operation by a user at the time of transmission and to select an applicable line by using a dial number accordant to a numbering plan and call progress sent back from a network. CONSTITUTION:When a call for a desired calling destination is to be executed, and when read information from a reader 15 is to be transmitted, the telephone number of the calling destination is inputted from the telephone number key of an operation part 3. A comparing circuit A6 compares the set number of a calling network designating number designating part 5 and an input telephone number from a memory 4, and when a user is the subscriber of VENUS-P, the comparing circuit A6 starts a digital network communication control part 10 according to the numbering plan, accesses an international line, compares a call progress code sent back from a digital line network and the set value of a switching progress designating part 7, and decides that G3 mode communication is to be executed when the call progress code and the set value are equal. In any other case, facsimile communication control in a G4 mode is executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that is connected to a digital line network and a telephone line network and is capable of facsimile communication between the two lines.

[Prior Art] Conventionally, in a facsimile device that is connected to a digital line network and a telephone line network and is capable of facsimile communication in G3/G4 mode between the two lines, the caller has to specify the line type of the destination. The system was configured so that users should check the information in advance, manually enter and select the appropriate line designation, and then send. .

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, the caller performs the operation after confirming the caller in advance, which has the disadvantage that the operation is complicated and the user may make a mistake in the specification. If you make a mistake in specifying the destination line, there is no way to switch midway through, and after communication becomes impossible, you have to specify the correct line type again and perform the above operation.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as one means for solving the above-mentioned problems.

That is, either a telephone network communication means for performing facsimile communication with a telephone line network, a digital network communication means for performing facsimile communication with a day or digital line network, the digital line network communication means or the telephone network communication means. a selection means for selecting and activating a call progress, a comparison means for comparing whether or not a call progress received from a digital line network is a specific code while the selection means is selecting a digital network communication means; When it is determined that reception has been received, it instructs the selection means to start the telephone network communication means instead of the digit tag network communication means. and a switching means.

[Effects] In the above configuration, even if the called destination line type is different, the connection is automatically made to the correct line network.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment according to the present invention,
In the figure, 1 is a controller that controls the entire embodiment according to the program shown in FIG. 2, which will be described later, stored in a ROM 2, 2 is a ROM that also stores parameters used in this embodiment in addition to the above-mentioned program, and 3 is a controller that controls the entire embodiment according to a program shown in FIG. an operation section consisting of a telephone number key for inputting a call destination number, etc., a start key for starting facsimile communication, etc.; 4 a memory for temporarily storing the input telephone number etc. from the operation section 3; 5;
is a calling control designation number designation section used to determine the type of the called destination line network, and a designation number is set by the controller 1. However, it may also be configured to include a switch or the like and register this number depending on the setting state of this switch. 6
Comparison circuit A compares the calling pattern designation number designating unit 5 with the called destination telephone number sent from the memory 4, and if they match, outputs a match signal. 7 is a call progress "missing number" code (switching progress). a switching progress specification section that specifies
8 compares the "missing number" code from the switching progress specifying section 7 with the call progress returned from the digital line network 20 indicating the connection status of the destination terminal, and selects the "missing number" code from the digital line network 20. The comparison circuit B, which outputs a matching code when it detects a match with the "missing number" code, selects either the digital network communication control section 10 or the telephone network communication control section 11 according to the matching signals from the comparison circuit A6 and the comparison circuit B8. The switching circuit 10 is a digital network communication control unit that controls the communication interface with the digital line network 20, and in this embodiment, it controls communication in the known facsimile 64 mode. Reference numeral 11 denotes a telephone network communication control unit that controls the communication interface with the telephone line network 30, and in this embodiment controls communication in the 03 mode of the facsimile.

Reference numeral 15 is a reader that reads a placed document under the control of the controller 1 and sends the read image information to the digital network communication control unit 10 and the telephone network communication control unit 11; 16 is a digital network communication control unit under the control of the controller l; 10 and the telephone network communication control unit 11. Further, 20 is a digital line network, and 30 is a telephone line network.

In the above configuration, a call is made to a desired destination, and the reader 1
When transmitting the read information from 5, the operator inputs the telephone number of the calling party using the telephone number key of the operation section 3. This input telephone number is temporarily stored in the memory 4. On the other hand, the controller 1 includes a calling tone designation number designation unit 5.
For example, the first four-digit number "4401" indicating the service user number of the international data line VENUS-P is set in the calling arrangement designation number designation section 5. Therefore, the comparison circuit A6 compares the setting number of the calling pattern designation number designating section 5 with the input telephone number from the memory 4, and outputs a match/mismatch signal to the switching circuit 9.

The switching circuit 9 inputs the match/mismatch signal from the comparison circuit A6, selects and activates either the digital network communication control section 10 or the telephone network communication control section 11. Then, the document information input from the reader 15 is transmitted to either the selected digital line network 20 or telephone line network 30.

When a call is received from the connected line network, the communication control unit connected to the network is activated, and the activated communication control unit performs normal reception processing and sends the received image to the printer 16. Output.

The detailed algorithm will be explained below with reference to the flowchart of FIG.

First, in step S1, the controller 1 checks whether or not there is a call request such as input of a telephone number from the operation section 3. If there is no call request, the controller 1 proceeds to step S2 and performs corresponding processing. For example, when either the digital network communication control unit 10 or the telephone network communication control unit 11 receives a call from the line network, and the corresponding communication control unit is activated, the incoming data is received and the printer Processing such as printing is performed from 16.

On the other hand, if there is a call request in step S1, the process advances to step S3, and the telephone number input from the operation section 3 is stored in the memory 4. This process continues until the start key is input, and when the start key is input, the process advances from step S4 to step S5, and the controller 1 receives a number preset in the ROM 2 (or a number set by an unillustrated switch circuit). number) to determine whether this terminal is a VENUS-P subscriber.

As a result of the determination, if this terminal is a subscriber of VENtJS-P, the process advances to step S6, and the input telephone number to the memory 4 is 9 digits according to the number plan, and the first 4 digits are "4408".
Check whether it is. If the first four digits are "4408", the process advances to step SIO, where the digital network communication control unit 10 is activated and the international line is accessed. If the other subscriber does not exist as a result of access, a call progress code indicating a "missing number" is returned from the network, so comparison circuit B
8 is the call progress code and switching progress specification section 7 returned from the digital line network in the subsequent step Sll.
If they are equal, it is determined that G3 mode communication will be performed (when a missing number code is sent) and the process advances to step S12. In step S12, the telephone network communication control unit 11 is activated, and in step S13, a call is made to the telephone network 30, and facsimile communication in G3 mode is performed.

If it is determined in step Sll that a code other than "missing number" is returned, the process advances to step S15 and facsimile communication control in G4 mode is executed. If another call progress code is sent, the corresponding process is executed to indicate that the other party is a G4 mode communication terminal, but another network failure has occurred. do.

On the other hand, if the terminal is not a VENUS-P subscriber in step S5, and if the first four digits are "4408" in step S6,
If not, the process advances to step S20, and it is checked whether the user is a VENUS-P service user via an NTT line. Here, if the user is a VENUS-P service user via an NTT line, the process advances to step S21, and it is determined whether the first number is "4401" among the 11 digits according to the numbering plan. If the first number is "4401", the process proceeds to step S12 and subsequent steps, and the digital network communication control unit 10
Start up and access the international line as well.

If you are not a VENUs-P service user in step S21 and if the first number is not "4401" in step S21, the process advances to step S22, and the first digit is "0".
Check whether it is or not. If the first digit is "0", the called destination telephone number is a long-distance prefix number to the telephone line network 30, so the process proceeds to step S12 and subsequent steps, starts the telephone network communication control unit 11, and connects the telephone line network Perform facsimile communication with 30 in 03 mode.

If the first digit is not "0" in step S22, the process proceeds to step S25, and the number is 7 digits according to the domestic line numbering plan of the digital line network 20, and the first 2 digits are a number specified by the region. If the number is specified by the region, the process similarly proceeds to step SIO, and facsimile communication is performed via the digital line network 20.

As explained above, according to this embodiment, by using the numbering plan and the "missing number code" of the call progress code, it is possible to automatically select a line without requiring the user's intervention. .

Of course, in the case of the second or subsequent transmission using the same number, if the previous transmission mode is memorized, the line type can be accurately and automatically determined without any need for a determination routine.

Note that the same digital line has both a packet-switched network and a circuit-switched network, so it is necessary to check in advance which network the transmitting side is compatible with and whether or not communication is possible. However, in the case of a facsimile, in general, the 04 machine is compatible with a circuit switched network due to its nature, so if the facsimile to be transmitted is compatible with a circuit switched network, there is no need to take this into account.

Since the flowchart shown in FIG. 2 shows the case of a packet switching network, there is a determination routine for VENUS-P, but in the case of a circuit switching network, this step S5.6.
It is natural that 20.21 becomes unnecessary.

[Other Examples] The present invention is not limited to the above embodiments, and can be modified in various ways. For example, as another embodiment, the comparator circuit A
6, B8, etc., without having a special hardware circuit, these may be determined by program control (software) of the controller 1 and the connection line network can be switched.

In addition, if you add a function to the 04 function that checks the ID (abbreviation) of the recipient on the sender side, it will be possible to check whether the destination has been selected correctly, so there will be no problem in terms of confidentiality. .

As explained above, according to this embodiment, a means is provided for detecting a match with a "missing number" code in the call progress indicating the connection status of the destination terminal returned from the digital network, and switching to the G3 mode. By providing a means to select the G3/G4 mode by comparing the dialed number entered by the user with the number according to CCITT recommendations, X, 121, and the national numbering plan, the corresponding line can be automatically selected without user operation .

[Effects of the Invention] As explained above, according to the present invention, by using the dialed number according to the numbering plan and the call progress returned from the network, the user's operation at the time of transmission is simplified, and the corresponding You can select the line.
