Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device system comprising a plurality of telephones and a plurality of data communication devices connected via a communication medium.

[Prior Art] A conventional communication system in which a plurality of telephones and a plurality of data communication devices are connected via a plurality of communication media includes, for example, a line and an outside line connected to a facsimile machine and a key telephone. There is a system that includes a main controller that accommodates a large number of lines and controls communication paths between each line.

An example of the configuration of this system is shown in FIG. As shown in FIG. 6, a plurality of button telephones AlO2 to button telephone Al
O4 and facsimile machine 110 each have extension 1.
31 to 134, and controls the formation of communication paths between these extensions and the communication paths between the extensions and connected external lines 121 and 122. The main controller 101 also includes a power supply unit that supplies power to the key telephone.

On the other hand, as another example, the line 131 connected to the facsimile machine 110 may be a line different from the other extension lines 132 to 134, and this line is normally set to the outside line 121 or the outside line 1.
22, and the manual disconnection consists of a pair of signal lines configured to be disconnected from the outside line using a device or the like. And button telephones 102 to 104
is the dedicated telephone for the main controller, and line 1 is the connection line.
32 to 134 include one pair of signal lines for control and power supply in addition to the normal line signal line, making a total of two pairs of signal lines.

However, in such a system, the button telephone and facsimile device have no relationship with each other; the facsimile device is simply connected to the control device of the button telephone, and there is no organic connection between them. It's not a thing. Therefore, when the line to the facsimile machine is not in use, the key telephone has only the ability to perform call processing using the line for the facsimile machine.

[Problems to be Solved by the Invention] For this reason, when a facsimile device, which is a non-telephone terminal, is transmitting and receiving information, it is not possible to reserve a call from the telephone, and there are only a few cases where facsimile devices are exclusively used for facsimile devices. There were only some that allowed you to make reservations for calls (telephone calls) with an attached telephone that was integrally connected to the device.

This has the disadvantage that the user has to go to the non-telephone terminal and operate it each time.

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

That is, in a communication device system in which a plurality of telephones and a plurality of data communication devices are connected via a communication medium, the data communication device calls a communication partner of the data communication device from a connected telephone during data communication. Have the means.

The present invention includes a calling means for selecting and calling a connected telephone specified by the calling means, and a communication path forming means for forming a communication path with a call request destination in response to a response from the telephone in response to the call made by the calling means.

[Operation] In the above configuration, the data communication device can communicate with a desired telephone (with a desired operator) even during data communication.
A communication device system capable of making telephone calls can be provided.

[Example] Hereinafter, an example according to the present invention will be described in detail with reference to the drawings.

Since these reception processes are also well known, detailed explanation will be omitted.

Next, telephones A to C (12
1 to 124) will be explained in detail below with reference to FIG.

In Fig. 3, 201 is a built-in ROM 201a.
A control unit 202 controls the entire telephone of this embodiment according to the program shown in FIG. 203 is a handset, 204 is a signal tone generation circuit that outputs various signal tones to the line, 205 is a speaker circuit for monitoring speech sounds on the line, 206 is a keyboard including a numeric keypad for inputting a telephone number; 207 is a display unit that displays various displays under the control of the control unit 201; 210 is a data interface that controls the interface with the data transmission control circuit 14;

Further, 213 is a call request button press detection circuit which outputs a pulse to the call call display circuit 214 every time the call request button is pressed. 214 makes a "call call" every time a pulse signal is received from the call request button press detection circuit 213.
This is a call display circuit that repeatedly turns on and off the display.
The signal line 221 is energized when the "calling" display is lit. Further, the call display circuit 214 is connected to the control unit 201.
By inputting the display reset signal 222, the "calling" display is forcibly turned off.

Reference numeral 215 denotes a pseudo-bell sound generating circuit that generates a pseudo-bell sound under the control of the control unit 201. This pseudo-bell sound may be generated directly by the pseudo-bell sound generation circuit 215 or may be generated via the speaker circuit 205. Further, 216 is a call switch, which outputs an input signal to the control unit 201 every time the switch ≠ is input.

In normal telephone calls, when the line switching circuit 4 selects a connection line and outputs a called signal, a ringing tone is output in response to the called signal. When the operator hears this and picks up the handset 203 of the telephone, a DC loop is formed in the line, and the line switching circuit 4 detects this, detects a response from the telephone, and forms a communication path.

In this embodiment having the above configuration, when image information communication processing is being performed between the facsimile units 152 of the respective control devices 150 on the sending side and the receiving side, from the telephones connected to each device, You can call any telephone of the other party.

First, a general process will be described below when an operator reservation is made to form a communication path between a telephone connected to the transmitting side control device 150 and a telephone on the other party (receiving side).

In this embodiment, this operator call is actually performed after all image information has been sent. When the control circuit 1 receives the calling telephone information of the other party from the telephone, which will be described later, after sending all the image information, the control circuit 1 sends a call request signal (for example, PIF (Facsimile Information Field ) with a PRI-EOP signal). for example,
A 1-byte calling telephone designation area is provided as a PIF signal, and the signal is sent to the other party, and when the other party's telephone responds within a predetermined time and receives a response signal (for example, a PIF signal),
A control signal is output to the telephone that has made the call request to generate a pseudo-bell sound, and the corresponding telephone is made to output the pseudo-bell sound.

When the operator responds to this pseudo-bell sound, a DC loop is formed in the line, and it is detected that the call switch 216 has been pressed, the output of the pseudo-bell sound is stopped.
A communication path is formed between the answering telephone and the destination telephone,
Allows calls between both phones.

On the other hand, if an operator call request is received from a telephone connected to the transmitting device while image information is being received, the receiving device receives a call request that includes the calling telephone information from the transmitting device after receiving the image information. When a signal (for example, a PRI-EOP signal having a PIF (facsimile information field)) is received, the connected telephone specified by the PIF signal is controlled to generate a pseudo-bell tone. When the operator responds by pressing the call button, etc., the output of the pseudo-bell sound to this telephone is stopped, and a signal (for example, PIF signal), connects the connection line and answering telephone, and forms a communication path. In this embodiment, response detection by a telephone is not limited to a response from the telephone that generated the pseudo-bell sound, but also detects a response from another telephone while the pseudo-bell sound is being output. It is assumed that this is a response from the designated called party from another telephone, and a communication path is established with the telephone that has responded.

In addition, if a normal call request signal (such as a PRI-Q signal) that does not include information specifying the telephone to be called is received, all connected telephones will receive a pseudo-bell tone. output.

Next, a case will be described in which an operator call request is received from a telephone connected to the receiving device during image information transmission. The telephone call on the receiving side is made when the reception of one page of the document is completed.

When the control circuit 1 receives a call request signal containing calling telephone information (for example, a PIF signal having a PIF (Facsimile Information Field)) from a receiving device (such as 60), the control circuit 1 performs the connection specified by the PIF signal. Controls the telephone to generate a pseudo-bell tone. When the operator responds by pressing the call button, etc., the pseudo-bell sound output to this telephone is stopped, and a signal indicating that the telephone has responded to the other party's device (for example, PRI -Q signal) to connect the connection line and answering telephone, and form a communication path. In this embodiment, response detection by a telephone is not limited to a response from the telephone that generated the pseudo-bell sound, but also detects a response from another telephone while the pseudo-bell sound is being output. It is assumed that this is a response from the designated called party from another telephone, and a communication path is established with the telephone that has responded.

Additionally, if a normal call request signal (for example, an FTP signal) is received that does not include information specifying the telephone to be called, a pseudo-bell tone will be output to all connected telephones. let

On the other hand, the operator reservation designation control of the receiving device at this time is such that when the control circuit 1 receives the calling telephone information of the other party from the telephone described later, it should call the other party's device after receiving one page of image information. A call request signal containing telephone information (for example, a PIF signal having a PIF (facsimile information field)) is sent out. When the other party's telephone responds within a predetermined time and receives a response signal (for example, a PRP-Q signal), a control signal is output to the telephone that made the call request to generate a pseudo-bell tone, and the corresponding telephone Outputs a pseudo bell sound.

When the operator responds to this pseudo-bell sound, a DC loop is formed in the line, and it is detected that the call switch 216 has been pressed, the output of the pseudo-bell sound is stopped.
A communication path is formed between the answering telephone and the destination telephone to enable communication between the two telephones.

The details of the above operation control are shown in Figures 4 (A) to (D) and 5.
This will be explained below with reference to the flowchart shown in the figure.

First, the communication control operation of the control device 150 shown in FIG. 2 will be explained with reference to FIGS. 4(A) to 4(D).

When the control device 150 is powered on, the process proceeds to step S1, instructs the line switching circuit 4 to open the line 31, and in the subsequent step S2, controls the data transmission control circuit 14 to switch all connected telephones. A reset signal is output to de-energize the call display circuit 214, followed by step S3.
The pseudo bell sound generating circuit 215 is deenergized. Then, in step S4, it is monitored whether a call request is input by inputting a one-touch dial or abbreviated dial on the operation unit 22, or whether the handset 203 of the connected telephone is off-hook and a call request is made. If there is a call request, the process proceeds to step S5, and it is checked whether or not the facsimile communication transmission mode is set at this time.If the facsimile communication transmission mode is not set, the process proceeds from step S5 to step S6, and a known predetermined telephone line is set. Performs call processing.

On the other hand, in the case of facsimile transmission mode, step S5
The process then proceeds to step S10, where the line switching circuit 4 is instructed to form a DC loop on the line 31 to issue a call request, and the line 31 is connected to the hybrid circuit 6. In the following step Sll, pre-procedure processing is executed to perform processing such as synchronization with the receiving side device, and the process proceeds to step S12. Then, the transmission image information is read from the transmission document set in the reader 10, and transmitted, for example, one page to the recipient. When the sending of the image information is completed, the process advances to step S13, and the P I
The F/PIN signal is received and it is checked whether an operator call has been received from the other party. If the operator has not been called, the process advances to step S30; if the operator has been called, the process advances from step S13 to step S.
Proceed to step 15. In step S15, it is checked whether telephone designation information for any of the connected telephones is included. Specifically, it is checked whether the PIF/PIN signal includes PIF. If the telephone designation information is included, step S15
The process then proceeds to step S16, where the connected telephone specified by the received PIF signal is controlled to generate a pseudo-bell tone, and the process proceeds to step 818.

On the other hand, if a normal call request signal (for example, a PIF signal) is received that does not include information specifying the telephone to be called, the process advances to step S17, and all connected telephones receive a pseudo call request signal. Control is performed to output a bell sound, and the process proceeds to step S18.

In step S18, it is monitored whether the operator responds within a predetermined time, such as by pressing the call button on the telephone that outputs the pseudo-bell sound. Here, if there is no response within the predetermined time, the process advances to step S19, where it is checked whether there is still a document to be sent, such as when there is still a document to be sent on the reader 10, and there is a document to be sent. If so, the process advances from step S19 to step S20, where the previously energized pseudo-bell sound generation circuit 215 is deenergized to eliminate the pseudo-bell sound, and the process returns to step S12 to continue transmitting the next page. If there is no document to be transmitted, the process advances to step S21, performs a known post-procedure process, and returns to step S2.

On the other hand, if a response such as input of the outgoing call switch 216 is made within a predetermined time, the process advances from step S18 to step S22, where the output of the pseudo-bell sound to the previously activated telephone is stopped, and in step S23 the other party A signal indicating that your phone has responded to the other device (for example, P
RI-Q signal), and in step S24, the connection line and answering telephone are connected to form a communication path, and in step S2
5 to make a call.

In addition, in this embodiment, the response detection by the telephone is as follows:
Not only the response from the telephone that generated the ringing sound, but also
Even if there is a response from another phone while the pseudo ring tone is being output,
It is assumed that this is a response from the designated called party from another telephone that has responded, and a communication path is established with the telephone that has responded. Then, in step S26, the process waits for the call to end and the line to be released, and when the line is released, the process returns to step Sl.

On the other hand, if the operator has not been called in step S13, the process advances to step S30, and as in step S19, it is checked whether there is still a document to be sent, such as when a document to be sent is still placed on the reader 10. If there is a document to be transmitted, the process returns to step S12 to continue transmitting the next image information.

If it is the last document, the process advances to step S31, where the control signal 221 from the call display circuit 214 of the connected telephone is activated, and it is checked whether there is a call request. If there is no call request, the process advances to step 856 to execute post-procedure processing, and if there is a call request, the process advances to step S32. Then, it is checked whether the call request signal includes information specifying the telephone to be called, and if there is a call destination specified, the call request signal containing the telephone information to be called is sent to the other party's device (for example, step S33). PR with PIF
I-EOP signal).

On the other hand, if the call request signal does not include information specifying the telephone to be called, the process proceeds to step S34, where a normal call request signal (for example, a PRI without PIF) is used.
EOP signal).

Both then proceed to step S35.

In step S35, it is determined whether a response signal (for example, a PIF signal) indicating that the other party's telephone has responded within a predetermined time has been received. If a response signal is not received within a predetermined time, the process proceeds to step S56. move on. On the other hand, if a response signal is received within a predetermined time, the process advances to step S36;
A control signal is output to the telephone that has made the call request to generate a pseudo-bell sound, and the corresponding telephone is made to output the pseudo-bell sound. Then, in step S37, it is checked whether the operator responds to the pseudo bell sound within a predetermined time and a DC loop is formed in the line, or whether the call switch 216 is pressed and inputted to respond. If there is no response, the process proceeds to step S56, and if there is a response, the output of the pseudo-bell sound to the previously activated telephone is stopped in step S38, and the process proceeds to step S24.

On the other hand, if there is no call request in step S4, step S4
0, it is checked whether the called detection circuit 28 has detected a call from the line 31 or the like, and if the call has not been detected, the process returns to step S4.

Here, when the called detection circuit 28 detects a called signal, if a telephone that should output a calling signal (should ring a bell) is specified, it connects the designated telephone and the line 31,
Outputs a ring tone from a compatible telephone. Then, in step S41, it is checked whether or not a called signal has been received a predetermined number of times (for example, three times), and if the called signal has not been received, the calling is continued. If the handset 203 is picked up during that time, a communication path is established between the telephone set and the calling party, and a conversation is made.

If the handset 203 is not picked up even after receiving the called signal a predetermined number of times, the process advances from step S41 to step S42, instructs the line switching circuit 4 to respond by forming a DC loop on the line 31, and disconnects the line 31. Connect to hybrid circuit 6. Then, in the following step S43, it is checked whether or not data is received with a carrier signal, which is facsimile reception. If no carrier signal is detected on the line, it is not a data communication, so it is assumed that the call is a mistake, and the line is opened and restored in step S44, and the process returns to step S4. Note that if other specific processing is determined in step S44, the corresponding processing will be executed.

If it is a data signal in step S43, step S45
Then, pre-procedure processing, such as detection of various device states, is executed, and synchronization processing with the partner device is executed. Then, in the subsequent step S46, a process of receiving image information sent subsequent to the pre-procedure process is executed. At the same time, in step S47, the received information is sent to V27/V2 via the above-mentioned route.
The signal demodulated by the demodulator 16 is sent to the decoding circuit 17 without going through the memory circuit 19, and is printed out by the printer 18. When the reception of the image information is completed, the process advances to step S48, and it is checked whether or not there is an operator call request from the telephone connected to the transmitting device while the image information is being received. Specifically, after receiving the image information, it is checked whether a call request signal (for example, a PRI-Q signal with PIF) including calling telephone information has been received from the transmitting device. Here, if there is an operator call request, step S5
0, and it is checked whether the call request signal contains information specifying the telephone to be called. If information identifying the telephone is included, step S51
Then, the connected telephone designated by the PIF signal is controlled to energize the pseudo-bell sound generation circuit 215, thereby generating a pseudo-bell sound. On the other hand, if a normal call request signal (such as a PRI-Q signal) that does not include information specifying the telephone to be called is received, the process advances to step S52, and all connected The telephone is controlled to energize the pseudo-bell sound generating circuit 215 to generate a pseudo-bell sound. And step S together
The process proceeds to step 53, where it is checked whether or not the operator has responded by pressing the call button in response to this on the connected telephone within a predetermined time. If there is no response within the predetermined time, the process proceeds to step S54, where the previously energized pseudo-bell sound generation circuit 215 is deenergized to eliminate the pseudo-bell sound, and the process proceeds to step S55. In step S55, it is checked whether or not the last document information has been received, and if it is not the last, step S4
Return to step 8 and continue receiving the next page. If the last document has been received, the process advances to step S56, a known post-procedure process is executed, and the process advances to step S31.

On the other hand, if a response such as input of the outgoing call switch 216 is made within a predetermined time in step 353, the process advances from step S53 to step S60, where the output of the pseudo bell sound to the previously activated telephone is stopped, and step S
In step S24, a signal (for example, a PIF signal) indicating that this telephone has responded is sent to the other party's device in step S24.
Proceed to.

Furthermore, if there is no operator call request from the other party's device in step 348, the process advances to step S65, where it is checked whether or not there is a call request from the connected telephone, such as when the call switch 216 is pressed. If there is no call request, the process advances to step S55 to continue the data transmission process, and if there is a call request, the process advances to step S66.

In step S66, it is checked whether the call request includes designation information of the called party's telephone, and if there is telephone designation information, the process advances to step S67, where the call request signal includes the calling telephone information (for example, if the call request has PIF). PIF signal) is transmitted. Note that designated telephone information is stored in the FIF. Then, the process advances to step S70.

On the other hand, if the call request signal does not include information specifying the telephone to be called, a normal call request signal without PIF (for example, a PIF signal) is transmitted to the destination connection device. Then, proceed to step S70, step S
In step S70, it is checked whether a response signal (for example, a PRI-Q signal) has been received from the partner connection device within a predetermined time, and if it has not been received within a predetermined time, the process advances to step S55. If a response signal has been received within the predetermined time, the process advances to step S71, and the pseudo-bell sound generating circuit 215 of the telephone that has output the call request is activated to generate a pseudo-bell sound. Then, in the following step S72, a check is made to see if the call switch has been input from any of the connected telephones within a predetermined time, and the call request button press detection circuit 213 has detected this and notified the connection control device 150. Note that this response may not be valid even from any telephone, but may be valid only from the telephone that generated the pseudo-bell sound.

Here, if there is no response from the telephone and no notification has been received, the process advances to step S54, and if there is an input from the call switch 216, the process advances to step S73. In step S73, the pseudo bell sound generation circuit 215 of this answering telephone
is deenergized, the pseudo bell sound is stopped, and the process proceeds to step S24.

By controlling as described above, it is possible to talk to any telephone even while data is being sent and received, and the recipient can quickly obtain the desired reception information without taking unnecessary actions. .

In addition, the above explanation has been given using an example in which the telephone to be called can be specified in the call request signal, but the control for specifying the telephone and the analysis control of the telephone specification information are omitted, and the PIF signal is The configuration may be such that information identifying the telephone is not included in the information, and all telephones may be displayed and called.

Next, referring to FIG. 5, the control of the telephone in the above processing by the control device 150 will be explained.

The control unit 201 checks in step 5lot whether the data interface 211 has received a control signal from the data transmission control circuit 14, and if the control signal has not been received, checks in step 5102 whether there is any key input from the keyboard 206. . If there is no key personnel, the process returns to step 5101.

Here, if there is a key input from the keyboard 206, the process advances from step 5102 to step 5103, where it is checked whether or not the input is from the call switch 216. If the input is from the call switch 216, the process advances to step 5120, where the call switch 216 is pressed. If it is not an input, the process advances to step 5105 to execute the process corresponding to the key force, and after the corresponding process is completed, the process returns to step 5101 to prepare for the next key force. For example, when the handset 203 is off-hook and a telephone number key is input, the corresponding processing instructs the signal tone generating circuit 204 to send out a corresponding telephone number signal (DTMF signal, etc.), and the call switch 216 In the case of inputting the other party's telephone number after inputting , the input number is temporarily held and then output together with the call request signal.

On the other hand, if a control signal from the data transmission control circuit 14 is received, the process proceeds from step 5IOI to step Sl10, where it is checked whether the received control signal is an energizing signal for the call display circuit 214. If the activation signal is the activation signal, the call display circuit 21 is activated in step 5111.
4 is activated to display "calling", and the process proceeds to step 5115 in preparation for a response such as taking the handset 203 off-hook.

If the received control signal is not an activation signal for the call display circuit 214, the process proceeds to step Sl12, where it is checked whether or not a deactivation signal for the call display circuit 214 has been received. In some cases, step St 1
3, the call display circuit 214 is deenergized, and the process proceeds to step 5115.

If the received control signal is not a deactivation signal for the call display circuit 214, the process proceeds to step 5115, and step Sl 1
In step 5, it is checked whether the signal is an energizing signal for the pseudo bell sound generating circuit 215 or not. If it is the activation signal for the pseudo bell sound generation circuit 215, the pseudo bell sound generation circuit 215 is activated in step 5116 to generate a pseudo bell sound, and the process proceeds to step 5120.

If the reception control signal is not an activation signal for the pseudo bell sound generation circuit 215, the process proceeds to step Sl17, where it is checked whether or not a deactivation signal for the pseudo bell sound generation circuit 215 has been received, and the pseudo bell sound generation circuit 215 is turned off. If it is a positive signal, step 8
The process proceeds to step 118, where the pseudo bell sound generating circuit 215 is deenergized to stop the pseudo bell sound, and the process proceeds to step 5120.

If the reception control signal is not a deactivation signal for the pseudo bell sound generating circuit 215, the process proceeds to step 5119, where processing corresponding to the reception control signal is executed, and the process proceeds to step 5120. In step 5120, it is determined whether or not the call display circuit 214 is activated. If the call display circuit 214 is not in the call display state, the call flag is reset in step 5140, and the process proceeds to step 5125. If the call is displayed, step 5
The process proceeds to step 121, where it is checked whether the call flag in the control unit 201 has been reset. If the call call flag has been reset, the call call flag is set in step 5122, the timer flag is reset in the following step 3123, and the control unit 20 (not shown) is set in step 5124.
1 is set for a predetermined time, for example, a 5 second timer, and the process proceeds to step 5L25. In step 5L25, the current state of the telephone is transmitted as a control signal from the data interface 211 to the data transmission control circuit 14. The telephone status includes a call setting status, a calling telephone number information input status, a call switch input status, and the like.

On the other hand, if the call flag has been reset in step 5121, the process advances to step 5130, where it is checked whether the timer flag has been set. If set, the process advances to step 5125. If it has not been set, the process proceeds to step 5131, where it is checked whether the timer started previously in step 5124 has timed out. If the time has elapsed, the timer flag is set in step 5132, the calling telephone number input is cleared, and the process proceeds to step 5125.

If it is not timed out in step 5131, step 5
The process proceeds to step 135, and it is checked whether the designated input of the calling telephone number has been completed, and if the input has not been completed, the process proceeds to step 5125.
If the input has been completed, the input telephone number is stored in the memory in step 5136, a timer flag is set in step 5137, and the process advances to step 5125.

In addition, although the above explanation has been given as an example of a case where it is possible to specify a telephone to be called in a call request, control for specifying a telephone and specifying a telephone can be omitted and the telephone to be called can be omitted. If a response from one of the telephones is sufficient, in the above explanation, step 812
In place of control below 0, a control signal indicating the state of the telephone such as the state of the signal line 221 (calling state) and the on/off state of the call switch 216 from the call display circuit 214 is sent to the control device 150. You can control it like this.

As described above, according to this embodiment, when data is received by the data communication device, the reception can be known from a nearby telephone, and the received data can be quickly retrieved.

As a result, even if the telephone is placed on the desk and the facsimile machine is placed in the corner of the room, the recipient of the information can immediately know that the information has been received while sitting at the desk. The received information can be immediately output.

[Second Embodiment] In the above embodiment, an example was explained in which a "call" is made from a connected telephone, but the system does not need to be a system in which a data transmission device and a telephone terminal are connected; It is also possible to connect a dedicated telephone, arrange a call request button in the operation section, and input the telephone number within a predetermined time using the button input function. Accordingly, when the operator is near the facsimile section 152, there is no need to go to another telephone installation location.

[Third Embodiment] The above explanation has been made with reference to an example in which the telephone number of the communication partner is entered and the display destination telephone is specified manually using this number, but the present invention is not limited to this, and the present invention is not limited to this. Rather than specifying the recipient's phone by inputting it, the receiver inputs the name, etc., and has a table that associates names and phone numbers on the sending or receiving side, and identifies the phone number by referring to this table. You may. Furthermore, the corresponding name on the phone is 1.
However, if a plurality of phone names are given, one telephone may be specified for each phone number.

If the name is sent to the recipient and there is no corresponding name, the phone corresponding to the name closest to the name can be identified.

By configuring in this way, it is possible to specify by a commonly used name rather than a list of numbers that are difficult to remember, and it is possible to provide an easy-to-use device that does not cause specification errors.

[Fourth embodiment] Also, in the above explanation, there is one external connection line (external line).
Although the case of a book has been described as an example, it goes without saying that multiple outside lines may be input. Similarly, it goes without saying that a configuration with a plurality of communication devices may also be used.

For example, consider a case where two communication devices are in operation.

At this time, the connection button telephone is configured to be able to display the telephone number of the outside line connected to the movable communication device and the ID of the communication device connected to the outside line. For example, if communication devices are connected to outside line 1 and outside line 2 and are in operation,
phone number (aaa-bbb-cccc) and ID (X
YY Co., Ltd.), external line 2 phone number (AA-BBB-
CCCC), and the ID of outside line 2 (X Co., Ltd. yy department) is displayed.

When making a telephone reservation from a telephone, for example, after pressing the telephone reservation button, press and input the specified outside line number that is displayed, and if necessary enter the telephone number of the telephone connected to the other party's communication device. Press to input.

Furthermore, when receiving a telephone call from the other party, the telephone may be configured to output only information on the outside line that made the call, and to notify the operator from which outside line the call was made.

[Fifth Embodiment] In the above description, an example has been described in which a call is made after starting data communication, but this is not limited to after starting data communication, and it is also possible to make a call before starting data communication.

In other words, even if the fax machine is set to automatically receive calls,
It is also possible to make a preliminary telephone call that enables a telephone call to be made with a telephone designated by a call request signal from the calling party without entering the data transmission mode.

In this case, after receiving the initial identification signal from the calling side, a call request signal (e.g. PR'I-Q signal) containing pre-designated calling telephone information in the PIF is sent, and the receiving side sends a call request signal (for example, a PR'I-Q signal) that includes the calling telephone information. When a call request signal having a PIF is received, the specified telephone may generate a ringing tone to notify the information recipient.

As a result, information can be transmitted after confirming that the recipient is present, and wasteful transmission can be prevented.

[Effects of the Invention] As explained above, according to the present invention, a person who should receive information can reliably and quickly know that the information has been received, and can quickly obtain information while also reducing waste. This will prevent you from making any strange movements.
