Abstract

PURPOSE:To call a FAX telephone from a telephone which has not a FAX by providing a specific code of a push-phone and providing the FAX with a means which detects the specific code to generate an alarm and allowing an operator to switch a line from the FAX to the telephone and call. CONSTITUTION:An MF tone detecting part 10 sets a specific call code and is provided with a means which detects its MF tone, namely, 941Hz frequency and 1,209Hz frequency; and when these two frequencies are detected, the detection signal is sent to a main control part 1 to sound a buzzer 8. If the operator hears this sounding to hook off a telephone 6 and depressed a switch S3, the telephone 6 and a telephone line 100 are connected to make it possible to call the push-phone.

Description

[Detailed Description of the Invention] [Summary] When the operator telephone of a facsimile machine (hereinafter referred to as FAX) is set to automatic incoming call mode,
You can make a phone call during the fax procedure, but the phone is connected to the fax
Now, you cannot make a call to that fax phone.

The present invention provides a specific code for the push-tone phone that commands a telephone call, and also provides a means for detecting the specific code and generating an alarm in the FAX machine.
To provide a calling system in which a telephone is switched from an AX to a telephone.

[Industrial application field]

The present invention relates to a telephone calling system for a facsimile machine.

A FAX that is equipped with a network control device and performs facsimile communication over a telephone line is well known.

The above network control equipment is usually equipped with a telephone for the operator to make calls, but when the fax is set to automatic incoming call mode, it is not possible to call the fax and make a call except for the fax procedure. . Therefore, it was not possible to call a FAX from a telephone without a FAX, and it was inconvenient to call an operator.

FAX is normally set to automatic call receiving mode, and there is a need for a telephone calling system for FAX that solves the above-mentioned problems.

[Conventional technology]

A conventional example will be explained with reference to FIG.

Figure 3 (al is a block diagram of the line connection part of a facsimile machine that can make FAX-to-FAX telephone calls; Figure 3 (bl
is a diagram showing a calling procedure.

A FAX that uses a telephone network is equipped with a network control unit (NCU) 4 that has a line connection function, and when the FAX is set to receive calls automatically by switch S1 on the operation panel, the NCU 4 detects the ring tone 1611Z. Then, the modem 3 is connected to the telephone line 100, and facsimile reception is automatically started.

That is, the NC1J4 is equipped with a 16H2 detection section 5 that operates when an automatic call is received, and when the 1611Z detection signal 50 is sent to the main control section 1, the main control section 1 turns on the line hold signal 51 and causes the NCU 4 to switch the switch S. The telephone line 100 is connected to the modem 3 through the telephone set 6.

As described above, telephone calls cannot be made with a FAX in automatic call receiving mode, but telephone calls can be made by following the steps below during facsimile communication.

During facsimile communication, when switch S2 (telephone reservation switch) is pressed, a procedure interrupt affirmative signal (PIF) is generated when the page transmission or end of transmission is called by the receiving side, and a procedure interrupt EOP signal (PI?1-) when the transmitting side calls. HOP
), and the buzzer sounds on both the transmitter and receiver.

Due to the ringing, both operators hook off their telephones and press the switch S3 (call switch), and the main controller 1 turns off the line hold signal 51 and connects the telephone line 1.
00 is disconnected and switched to telephone 6.

[Problem that the invention seeks to solve]

As explained above, F
'AX cannot be called directly from a telephone using conventional methods.

In view of the above-mentioned problems, the present invention has been developed to
The purpose of this invention is to provide a calling method for calling an AX telephone.

[Means for solving problems]

For the above purpose, the telephone calling method of the facsimile machine of the present invention, as shown in the principle explanatory diagram in FIG. Means of occurrence (10)
and a means (3) for switching the line connected to the facsimile machine to the telephone set, the operator of the facsimile machine being called by a push-tone telephone and the line being switched to the telephone set.

[Effect]

In other words, an MF tone signal with a specific code of a touchtone (encoded by a combination of two-frequency tone signals) is sent to the FAX.
A circuit for detecting the MF tone is provided, and means for sounding a buzzer when the MF tone is detected is provided.

To call a FAX, dial from the push-tone phone, confirm the connection, and then press a specific code such as "*".
The AX side detects the MF)-on and sounds a buzzer.

When the operator hooks off the telephone and presses the switch S3, the operator can switch from the FAX to the telephone and make a telephone call using the touch-tone telephone.

〔Example〕

The details of the present invention will be explained according to the embodiment shown in FIG.

FIG. 2 (al is a block diagram of the embodiment, showing only the FAX line connection part.

In the figure, reference numeral 10 denotes an MF tone detection unit, which is equipped with means for setting a specific call code, for example "*", and detecting the MF tones, that is, frequencies 941H2 and 1209+12. When detected, a detection signal is sent to the main control section 1 to cause the buzzer 8 to sound.

Others in FIG. 3 (the same symbols as al represent the same objects.

The operation will be explained below.

(When calling the 11 FAX operator, dial the FAX phone number using the touch-tone telephone.

(In the 21NCU4, the 1611Z detection unit 5 detects the ring tone 16
112 and sends the 16+12 detection signal 50 to the main control unit l.
Send to.

(3) The main controller 1 connects the telephone line 100 to the modem 3 and sends out CHD and DIS signals to start facsimile communication, but the caller checks the connection console and enters a specific call code "*". Press down.

(MF of 41941/1209H2)-- is sent to the FAX, the MF tone detection unit 10 detects this and sounds the buzzer 8.

(5) When the operator hooks off the telephone 6 by this ringing and presses the switch S3, the telephone 6 and the telephone line 100 are connected, and a call using the push-tone telephone is enabled.

As described above, the FAX is equipped with a circuit that detects the MP tone of a specific call code of the touchtone, and when the MP tone is detected, the buzzer is sounded to call the operator.

Note that the call code for the push-tone phone is not limited to "*", and a combination of numbers may also be used.

〔Effect of the invention〕

As explained above, the present invention provides a method for calling a FAX in automatic reception mode from a push-tone, and allows calls to be made by telephone that could only be made using the conventional FAX procedure. The benefits of being able to make calls from anywhere are great.
