Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a communication system comprising communication devices such as a plurality of telephones, and a communication device having a speed dial function such as a facsimile. More particularly, it relates to a communication system in which these communication devices can share speed dial functionality.

[Prior Art] Conventional facsimile devices or private telephone devices are generally equipped with a so-called "speed dial" function.

This function includes "one-touch dialing," which allows you to make a call to a registered phone number by pressing a key such as a single digit number, and calling a registered phone number by pressing a combination of a shortcut function key and a number key. There is a narrowly defined "speed dial" for making calls.

On the other hand, facsimile machines, telephones, etc. can only perform their functions after being connected to a public telephone line. but,
Since facsimiles are not always in operation, it is not a good idea to set up a dedicated facsimile line from the standpoint of running costs. In view of this point, the applicant of this case has proposed a facsimile machine with a built-in circuit switching circuit. That is, in this facsimile, a plurality of telephones and the facsimile share a public line, and the switching circuit performs the switching operation.

[Problems to be solved by the invention] By the way, telephones and facsimile machines have fundamentally different functions, so their abbreviated telephone numbers do not use each other's numbers. That is, the registered abbreviated number of the destination facsimile is not used from the telephone, and vice versa is generally not the case. Therefore, in principle, the abbreviated registration of general telephone numbers and the abbreviated registration of facsimile telephone numbers should be performed under different controls, but from the viewpoint of equipment cost, it is desirable to share them. Furthermore, if you have a facsimile with a handset, the handset can be used as a telephone, so when you make a call from this handset,
It is desirable to be able to access abbreviated general phone numbers.

Therefore, the present invention provides a communication system that includes a communication device having a circuit switching function, such as a facsimile having the above-mentioned multifunction function, and a communication device such as a BX-like telephone, and the communication system includes a communication device such as a BX-like telephone. It proposes a shared abbreviated phone number.

[Means for Solving the Problems] According to the present invention, a single first communication device connected to a public line network via a built-in line switching section, and the line in this first communication device A communication system comprising a plurality of second communication devices connected to a public line network by being connected to an exchange via a private line, wherein the first communication device communicates with itself and the plurality of second communication devices. The present invention is characterized by comprising a registration means for storing and registering an abbreviated telephone number for the second communication device.

[Examples] Examples according to the present invention will be described below based on the accompanying drawings.

Outline of Communication System> FIG. 1 is a block diagram of a communication system according to an embodiment. This system consists of a facsimile machine 1OO, a terminal device 200, a central office line 300, and a cable 400 (local line). The terminal device 200 includes a plurality of telephones as shown in FIG. 2 (three telephones 201 to 203 in FIG. 1). These three telephones are connected in series by a facsimile 100 and a cable 400.

This cable 400 includes an audio line that conveys an audio signal, a control line that conveys a control signal, and a power line that supplies a power supply voltage.

On the other hand, there is only one central office line 300 in the embodiment shown in FIG. Therefore, of the three telephones and one facsimile machine, only one of them is connected to the public line network via the central office line 300. Of course, by increasing the number of station lines, it is possible to increase the number of terminals that can operate at one time.

<Appearance of Apparatus> FIG. 2 shows the appearance of the telephone set 200. Among the buttons provided on the panel of this telephone, those related to the operation of the embodiment are briefly described as IrA, D to IrE,
! 1 is a one-touch speed dial button, and "Register" is a button for instructing speed number registration. Other "function" keys etc. will be described later.

FIG. 3 shows the layout of the operation panel of the facsimile machine 100. A brief explanation of the buttons provided on this operation panel, especially those related to the operation of this embodiment, is as follows: ``Start button'' is a button switch that starts facsimile transmission, ``One-touch dial'' is a button switch that starts facsimile transmission, and ``One-touch dial'' is a button switch that starts facsimile transmission. When pressed, the registered destination facsimile number is set. After pressing this button, "Shorten"
When the r one-touch dial J button is pressed, the registered abbreviated number is set. ``Registration J'' is a button for instructing abbreviated number registration, and ``R Telephone'' is a button for disconnecting the facsimile 100 from the central office line 300.

<Facsimile Apparatus> The configuration of the facsimile apparatus 100 will be described with reference to FIG. The calling circuit 102 is used when making a dial call from the facsimile 100 side (as described later, each telephone has a dedicated calling circuit). Exchange circuit 10
4 connects the central office line 300 to either the telephone 200 side or the facsimile 100 side through exchange. The terminal control circuit 103 mainly controls the exchange of control signals performed via the telephone 200 and the cable 400. Registration memory 112
is a memory that registers and stores abbreviated telephone numbers and one-touch dial numbers. The configuration of this memory 112 is shown in FIG.

In FIG. 1, 106 to 111 are parts for realizing a so-called facsimile function. The microcomputer 105 operates according to the control program 107 such as ROM.
This is the part that controls 6 to 111. That is, when receiving a facsimile, received image data converted into a digital signal by the modem 106 is stored in the image memory 109, and is decoded according to, for example, MH encoding or MR encoding.
It is output to the recording circuit 110. When transmitting a facsimile, image data read from the reading circuit 111 and stored in the image memory is encoded according to MH encoding or MR encoding, and transmitted onto the central office line 300 via the modem 106.

The line switching operation in the switching circuit 104 will be explained. When this system becomes the sending side, the microcomputer 105 causes the switching circuit 104 to switch the connection between the telephone 200 side and the facsimile 100 side in response to a call request from the telephone 200 or the facsimile 100. When you become the receiving party, send the called to the terminating circuit 1.
01 is detected, the microcomputer 105 notifies each telephone to that effect via the terminal control circuit 103.

Each informed telephone sets a pseudo ring tone. When the operator picks up the handset, the telephone notifies the microcomputer 105 via the control circuit 103. Then, the microcomputer 105 connects the office line 300 to the telephone side.

On the other hand, if the telephone receiver is not picked up even after the ringing tone is sounded for a predetermined period of time, the microcomputer 105 which has been monitoring the time operates to cause the switching circuit 104 to switch the central office line 300 to the facsimile side.

Telephone> Next, the detailed configuration of the telephone 200 (201-202) will be described below with reference to FIG.

In Fig. 4, 501 is a built-in ROM 501a.
A control unit 502 controls the entire telephone of this embodiment according to a program stored in the computer, and connects the communication line from the exchange circuit 104 to any one of the handset 503, the dial signal generation circuit 504, and the speaker circuit 505. This is an interface that connects either one of the control unit 501 and the control unit 501. 503 is a handset, and 504 is a dial signal generating circuit that outputs various signal tones to the line, that is, a calling circuit. Reference numeral 505 is a speaker circuit for monitoring the sound of a call on the line, 506 is a keyboard including a ten-key pad for inputting a telephone number, and 507 is a display unit that displays various displays under the control of the control unit 501.

Further, 511 is a data interface that controls the interface with the terminal control circuit 103, 510 receives power supplied from a power line (part of the cable 400),
This is a power supply circuit that supplies voltage to each component. A timing generation circuit 512 generates an operation clock signal for the control unit 501 and a timing signal for data transmission at the data interface 511. Telephone data interface 511 and facsimile 100 side terminal control circuit 10
3, various control commands and the like are inputted and outputted using, for example, FS-modulated modulation signals.

<Transmission control between F A x + "r E L> Then,
Next, data transmission of control signals between facsimile machine 100 and telephone 200 will be explained. This data transfer is performed by polling/selecting each telephone in turn, and as shown in FIG. 5, the polling/selecting cycle is T and is performed in an asynchronous mode. Each data consists of 8 bits, and for synchronization, the data is sandwiched between a start bit and a stop bit before and after the data. In FIG. 5, reception is indicated by REC and transmission is indicated by TRN when viewed from the telephone.

First, a synchronization signal having a predetermined bit configuration is sent from the facsimile machine 100 side. When the telephones connected to cable 400 detect this synchronization signal, each telephone knows that a polling/selecting sequence has begun and follows the device number given to the telephone, as shown in FIG. Perform timer monitoring at specified time intervals. For example, in the data transfer sequence of a telephone during facsimile, the first telephone (position L) receives the synchronization signal and then transfers the data to T.

The timer monitors the time, and the second telephone (position 2) monitors the timer for T2 time... it roars. The device number is °“l”
The explanation will be given using an example of transmitting and receiving data on a telephone. First, when a synchronization signal is detected, T.

In order to receive data (command) after a certain time, the timer is set to 1.
Set 0 hours. When the T3 time is up, data reception is performed. In this way, the first dedicated data is received. Next, a time T4-T is set in the timer, and when this time expires, the common data is received by the telephones 1 to 3. This common data is, for example, a case where the facsimile 100 is receiving a facsimile and sends display data indicating that the central office line is busy to all telephones.

In this way, data reception by the facsimile (FAX) φ telephone set is completed.

Next, T on the timer! - Set the time for T4, and when the time is up, send the data (request) to the telephone (station) -> facsimile. The above operation is repeated according to the period T.

Other telephones also perform similar operations, setting the time according to the terminal number.

<Registration operation> The one-touch and speed dial registration operations are explained below. One-touch dial registration is performed using the keys on the operation panel (Fig. 2). For example, A...03-123
-4567.

Since it is registered to the 6Jl key, when the In and 6Jl keys are pressed, 0''AJI is displayed. From now on, enter data using the 10 key and the "space" key. The "space" key may or may not be used. Control during this time is solely performed by the telephone controller 501. When the input is completed, press the start key to enter the data. For the registration of the B key, the same key operations as for the registration of the A key may be performed.

Speed dial registration is basically the same as one-touch registration, so a detailed operational explanation will be omitted.

When the registration operation by the telephone is completed until the "start" key is pressed, the telephone controller 501 stores data in the RAM.
501b, create data in the format shown in Figure 8D, and send it to the facsimile 10 at the fax transmission time.
0 side via the data interface 511=>terminal control device 103. In Figure 8D, “W/
"Short" is a bit for identifying one-touch/abbreviated registration, "
"REGISTRATION" is a registration request instruction bit, followed by an abbreviated number (or one-touch number), and then an actual dialed number. The facsimile machine that receives this data stores the received registration number in the registration memory 112 according to the configuration shown in FIG.

The configuration of the registration memory 112 will be explained with reference to FIG. Each entry is configured for each registration, and the first field indicates the type of registered number, one-touch/shortened (in a narrow sense). The next field is the one-touch number or abbreviated number. The next field is the registered legal phone number.

Making a call using abbreviated numbers> This section explains how to make a call using one-touch or speed dialing.

To make a one-touch dial call, press once the key in which the destination number is registered (eg, li'A, !l [rB, n) described above. To make a speed dial call, press the "*" key, then press
Use the 10 key to enter the number where the other party's number is registered.

It is that of 05.

When the key "AJ" is pressed, the program shown in Figure 1○A is called on the telephone side.In step 2, the status (busy/ready) of the office line 300 is read from the RAM 501b.This status is as follows: It is updated by periodic telephone transmission during facsimile (Fig. 8B).If the central office line 300 is not busy, the process proceeds from step 4 to step 6, and the outside line use request bit and the bit indicating B one-touch dialing are updated. , one-touch key number (dial address), etc., in the sending buffer of the telephone (SB in Figure 12).Then, in step 8, wait for the timing to send the facsimile in your telephone, and then At this point, it is transmitted in step 10. The transmission format at this time is shown in FIG. 8C.

When the facsimile machine that receives this data recognizes that it is a one-touch dial call from the outside mail request bit, one-touch bit, etc., it proceeds from step 50 (FIG. 11) to step 22, and registers it from the registration memory 112. Read out the authorized phone number. And step 23
Then, the switching circuit 104 switches the central office line 300 to the telephone set 200 side. In step 24, wait for the timing to send the one-touch request to the phone, and then step 2
At step 6, a notification that the central office line 300 has been secured and the authorized telephone number read out at step 22 are sent as data in the format shown in FIG. 8A. Phone number is 4 bits 1
Digits are sent. - Step 28. In step 30, a status bit and a message such as "Gaisen Showchu" are sent in the common format of FIG. 8B to notify other telephones that the central office line 300 is busy.

On the telephone 200 side that received the data shown in FIG. 8A, the first
In step 40->step 42 of the 0B diagram, the received data in the receive buffer (RB) is analyzed, and step 4
Verify that the outside line (office line) is marked busy in step 4, verify that the outside line is assigned to you in step 46, verify the dialing data (regular phone number) in step 48, and then , in step 50, the number is displayed on the display section 507, and the dial signal generation circuit 50
The calling operation starts from step 4.

Incidentally, FIG. 10C is a program for data reception by a telephone other than the one that made the one-touch request. Steps 66 and 68 are for displaying the telephone number of the other party when receiving a facsimile, for example. Step 70 is for displaying a message sent from the facsimile machine (for example, "Gaisen Shouchu!l").

<Effects of Embodiments> According to the embodiments described above, (1) one-touch dialing or speed dialing data of facsimile machines can be commonly used.

(2) Memory for one-touch dialing or speed dialing on the telephone is no longer required, and the device becomes inexpensive and has a simple configuration.

(3) Memory backup of the phone is no longer necessary.

In the above embodiment, the calling operation from the telephone side is performed by the calling circuit (dial signal generation circuit 50) provided within the telephone.
4), but this circuit may be shared with the facsimile side. That is, the calling circuit is located on the facsimile side and is shared.

Further, the communication device in the present invention is not limited to a facsimile or a telephone. In short, the present invention can be applied to telex, etc., as long as a telephone number is used. Therefore, the memory for storing the registration number need not be limited to the facsimile side, but may be provided wherever there is sufficient space.

Further, in the above embodiment, the abbreviated telephone number is registered and shared both from the telephone and the facsimile. A typical facsimile machine that can register an abbreviated number does not register a regular telephone number, and conversely, does not register a facsimile telephone number from the telephone. However,
In the communication system of the above embodiment, the facsimile number of the other party can be abbreviated and registered from the telephone, and vice versa. In this case, a case may occur in which the telephone of this embodiment makes a call by confusing the other party's regular phone number and facsimile number. In this case, if the other party's fax machine is a facsimile machine designed exclusively for facsimile machines, unless it is determined that the caller has confused the caller, the other party will have to wait forever to find out why the other party does not answer the phone even though there is a dial tone. become. In order to eliminate this inconvenience, the data stored in the registration memory shown in FIG.
Make sure to also store information to distinguish whether the phone is a regular phone or not. This information can be easily added during registration.

When dialing the abbreviated number, the telephone 200 (and facsimile 100) displays a display indicating whether the registered destination is a facsimile or a regular telephone.
It is installed on the panel. In this way, the other party's phone can be identified by the display, so even if you press the wrong speed code due to confusion, at least
You can learn about the incorrect operation.

[Effects of the Invention] As explained above, according to the present invention, in a communication system including a communication device having a circuit switching function and a communication device such as a general telephone, it is possible to exchange each other's registered abbreviated telephone numbers. It can be shared.
