Abstract

PURPOSE:To realize the automatic response of data transmission by a general subscriber telephone set, by providing a control means which judges whether transmission is the data transmission or not based on the presence/absence of high tone transmission from an opposite station at the time of receiving the transmission and changes a mode to a required reception mode based on a result. CONSTITUTION:The titled system is provided with a telephone circuit main body 3, a data transmission modem 4 which modulates/demodulates data to a trunk line signal, a voice signal recording means 5 which records a bit of message information as a voice signal, and a control means 6 which originates a required message to an opposite station by driving the voice signal recording means 5 when a line is connected to the telephone set of the opposite station, and judges whether the transmission is the data transmission or not based the presence/absence of the high tone transmission from the opposite station at the time of reception, and changes the mode to the necessary reception mode, based on the result. In such a way, the connection of a data transmitter by the automatic response can be realized in the general subscriber telephone.

Description

[Detailed description of the invention] Chestnut-grown chestnuts! TECHNICAL FIELD The present invention relates to telephone equipment, and more particularly to general subscriber telephone equipment to which an automatic answering data transmission device can be connected.

[Sub] Shigeru Mold For example, an answering machine is OGM (Out G).

ing Message-) and ICM (In C.

ming Message), and has an additional function that allows you to listen to the message content from outside as a remote control. A flowchart of the answering operation of this answering machine is shown in FIG. First, when you receive a call and receive a ring pulse 2-3 times, step #1
Proceed to #2, connect the tip rings with characteristic impedance (off-hook state), and connect the telephone line to the answering machine side. In step #3, play OGM and let the other party know that you have an answering machine. Next, the process proceeds to step #5, and the message from the other party is received by the ICM. If you confirm that the other party's message has finished in step #6, disconnect the line and wait for the next call (in an on-footer state).

Also, when listening to the content using the remote control, if it is confirmed that there is a call in step #5,
Proceed to step #7 and transmit the contents contained in the ICM to the called party. When the call is finished, the line is disconnected and the ICM is reset to wait for the next call in step #9.

On the other hand, the data transmission protocol on the general public line is as shown in FIG. First, when a telephone call is made and a ring pulse is received two or three times, the process proceeds from step #11 to step #12, in which the tip rings are connected with characteristic impedance and the telephone line is connected to the data transmission device. The operation up to this point is the same as in the case of an answering machine. Next, in step #13, an answer tone is output and the echo suppressor, etc. on the station side is disconnected (however, this process is
It is necessary in Be1l, but it is not necessary in Be1l.

). Next, proceed to step #14 and output a high tone to check the condition of the track. If a signal is being sent, it indicates that the originator (sending) side has received a high tone, and sends out a high tone.This high tone is answered (received).
After receiving it on the side (#15), data starts after a certain period of time (#16).

Then, when the data is mutually terminated (#17), there is no more data carrier. When it is confirmed that the data has finished, the line is disconnected (on-hook state) and the next transmission data is waited for (#18).

By the way, although answering machines and data transmission devices each have functions that allow them to automatically receive voice and data, a single telephone can handle both devices. It is impossible to give it any functionality. If one phone call
If you accept both regular telephone calls (voice) and data transmission, the following problems arise.

■When receiving a ring pulse and going off-hook, it is difficult to tell whether the data transmission is from a regular phone call or not.

■Answer tones, high tones, etc. on general telephone calls make it difficult to hear and can cause discomfort.

- During data transmission, the receiving side does not operate and remains silent until the high tone comes in (therefore, the answering machine records silence.

However, in today's world where the need for data transmission is increasing, it is very uneconomical to keep a dedicated telephone in order to enable data transmission when the user is away from home.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention aims to provide a new technique that enables connection of an automatic response data transmission device to a general subscriber telephone device.

1. In order to achieve the above-mentioned object of fortune-telling, the telephone device of the present invention comprises a telephone circuit body, a data transmission modem that demodulates data into a central office line signal, and records message information as an audio signal. A voice signal recording means is configured to drive the voice signal recording means when connected to the telephone of the other station to send a necessary message to the other station, and also to record a high tone transmission from the other station when receiving a message. The present invention is characterized by comprising a control means that determines whether or not data is to be transmitted based on the presence or absence of the data, and changes to a necessary reception mode based on the result.

The operation of the present invention will be explained in detail in the following examples.

However, FIG. 1 is a block diagram showing a data transmission device with an answering machine as an example of the present invention, where 1 is a 00M device, 2 is an I
It is a CM device. These devices 1.2 consist of, for example, tape recorders. 3 is a telephone circuit, which includes a connection device for connection to the general telephone network, a telephone transformer, a telephone handset,
It consists of a dialing device, etc. Reference numeral 4 denotes a data transmission modem device for demodulating data into a local line signal, which is composed of a data converter and a modem. Reference numeral 5 denotes an audio signal recording means for recording necessary message information as an audio signal, such as a speech synthesis circuit, a speech analysis and synthesis circuit, or a tape recorder. Reference numeral 6 denotes a central processing unit (hereinafter referred to as CPU; however, it includes ROM and RAM), which controls each of the above-mentioned devices 1 to 5 to perform predetermined operations.

FIG. 2 shows a flowchart illustrating control operations performed by the CPU 6 on the receiving side of data or general telephone calls. First, when a ring pulse is received in step #21, the tip-rings are connected by characteristic impedance (off-footer state) and connected to the answering machine side (step #22).

Then, the audio signal recording means is driven to record the time required for tasks such as data reception and other necessary information (
Step #23) Next, in step #24, an answer tone is output and the echo suppressor on the station side is disconnected.

Next, output a high tone (#25), and check the line condition and whether data is being transmitted (#26). This confirmation can be done by waiting for a carrier or high tone of data from the transmitter. In other words, if it is not sent from the sending side, it can be confirmed that it is not data transmission. If it is a general voice communication, play OGM again (#27), enter answering machine mode (#27 to #33), and process steps #27 to #33 in steps #3 to #9 in Figure 4. Since this is the same as before, the explanation will be omitted.

On the other hand, if it is data transmission, steps #26 to #34
Go to and enter data transmission protocol mode. Processing in this mode is shown in steps #34 to #37, which are the same as steps #15 to #18 in FIG.
Explanation will be omitted.

Next, FIG. 3 shows a flowchart illustrating control operations performed by the CPU 6 on the transmitting side.

First, step #41. After detecting that the receiving side receives the ring pulse two or three times and goes off-hook in step #42, the process proceeds to step #43, where the audio signal recording means is driven and the necessary message is sent to the receiving side.

When the transmitting side transmits data, the silent state continues until the receiving side emits a high tone as described above.

Therefore, if the receiving side responds manually instead of automatically, and data is sent, there is a risk that the receiving side will misunderstand it as a mistaken call or a prank call because the sending side is silent, and the line will be disconnected. Therefore, in step #43, a necessary data message is sent to notify the receiving side that it is a data transmission. As a result, even if the receiving side is in manual mode, if the message enters a silent state after receiving the message, the recipient will determine that it is a data transmission and will manually switch to the required mode. The processes following step #44 are necessary for data transmission. That is, a high tone is sent from the receiving side (#44), the high tone is sent back (#45), data is started (#46), and when the data carrier is finished (#47), the on-footer state is entered. Turn (94B).

As explained above, the telephone device according to the present invention includes a telephone circuit main body, a data transmission modem that demodulates data into a central office line signal, and an audio signal recording means that records message information as an audio signal. When connected to the telephone of the other station, the voice signal recording means is driven to send a necessary message to the other station, and when receiving, data transmission is performed depending on whether or not a high tone is transmitted from the other station. Since it is equipped with a control means that determines whether the reception mode is correct and changes the reception mode to the required reception mode depending on the result, it is possible to automatically respond to data transmission using a regular subscriber telephone, and a separate dedicated line for data transmission can be used. There is no need to install one, making it very economical and convenient.
