Abstract

PURPOSE:To improve the transmission efficiency and the reliability of transmission by registrating a telephone number or its part with deteriorated line quality and sending a data at the designated transmission speed when the registered telephone number or its part is called. CONSTITUTION:The telephone number of a destination for data transmission is registered to one-touch key 26 in advance. As to the transmission speed corresponding to the telephone number, the transmission speed set to be optimum depending on the characteristic of the communication line and in the actual operation is registered. When the operator selects the one-touch key 26 and depressed the key No.4, the telephone number and the transmission speed corresponding to No.4 are read from a telephone number memory 23 and a transmission speed memory 28. Thus, the deterioration in the transmission efficiency due to quality of line is avoided and the optimum transmission speed of one communication is decided.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a transmission speed designation device having a telephone function, and particularly to a transmission speed designation device that can designate transmission speed for each registered telephone number. It is.

・ [Prior Art] Conventionally, in the case of voice-data communication devices, for example, taking a facsimile as an example, since the facsimile is used as a data communication cover and a telephone line is used, a telephone function is added. Depending on the user's intention, one of these two functions can be selected for communication. Figure 4 shows
This shows the outline of this facsimile machine.As a data source to be transmitted, a document (1) is driven by a paper feed roller (10 and scanned in the horizontal direction). The nine-stroke data read by is processed for one line by the reading circuit (4), and when the processing by the encoder (5) is finished, the pulse motor drive (9) moves the paper feed roller α1 into the l-line feed system. , reads the next line.At this time, the encoder (5) encodes the data length of one line according to a certain rule and compresses the number of data.In the 03 recommendation as an international standard, the MH code MR encoding, MR encoding, etc. are determined. When the encoding by the encoder (5) is completed, the pulse motor drive (9) is driven.The encoded signal is sent to the modem interface +61) , a control signal, error correction encoding, etc. are applied, and at the transmission speed commanded by the transmission speed command (61), when the telephone-data switch (7) is on the data side, the transmission output terminal ( 6), the data is sent to the communication line (6).

Before this facsimile transmits data, the telephone (
From 8), the telephone-data switch (7) is a normal telephone, so it goes through the transmitting side output terminal (b) 1 communication line (6), the receiving side input terminal (to), and the telephone-data switch (to). A voice link is formed from the telephone to the telephone, which is called the telephone function. During manual reception, as mentioned above, both the telephone and data switch (7) and αυ are set to telephone, but when automatic reception is performed, the telephone and data switch (g) automatically detects the signal and switches to data. can be switched to the side.

Assuming that the signal has already been switched to the data side, the data signal received from the receiving side input terminal is decoded by the modem interface αQ to decode the 11 control signals, and only the encoded data is sent to the decoder (b). At this time, the transmission speed command (62) is transmitted to the telephone circuit 1 on the receiving side.
When the error rate of the communication line (2) is high, the transmission speed is fixed at a low speed and the receiver behaves as if it had a low speed transmission capability. decoder Q't)
The encoded data sent to is restored to image data for one line in the horizontal scanning direction and sent to the write circuit OsK. Here, the image is stored on the storage paper 3υ at a writing timing suitable for the thermal head (1). When the numbering for one line is completed, the pulse motor drive σ drives the discharge roller (F) to advance the recording paper (C) for the next one line. As mentioned above, the transmission speed command (61
)II'i, the speed command was only given to the modem interface (6), but the capabilities of the device itself were changed and applied to all communications. However, the error rate of the communication line is
It varies depending on the line used, the number of relay links (2), international communication, switching equipment characteristics, and maintenance conditions, and not all lines are unsuitable for high-speed transmission.With conventional methods, even lines capable of high-speed transmission are forced to operate at low speeds. The disadvantage was that it took a long time to transmit.

FIG. 5 shows the functions of the telephone (8) in more detail, particularly the one-touch or shortcut function. According to the registration key, the user can compare the phone number normally used with the individual numbers of the one-touch key (e), and for example, enter the key number 1 of the one-touch key W.
Click 06-491-8021 from the registration key (foundation).
If you enter , the main control @Yoshimi talk number memory (to) will be displayed.
to memorize 06-491-8021. You can register as many one-touch keys one after another. Users can memorize frequently used phone numbers. Now, when making a call, the user presses the one-touch key (1)
Pressing 1 of
Instruct them to dial 6-491-8021.

In the dial circuit (b), since the telephone-data switching circuit (7) is on the telephone side, the telephone number 06-491-8021 is sent out as a dial signal from the transmission side output terminal αη. Here, the line quality of the telephone line 1 communication line (6), especially the transmission speed command (61) based on the error rate, and the dialing signal transmission of the telephone number are set independently and have no relation to each other. The drawback was that the transmission speed could not be changed depending on the line quality.

[Problem to be solved by the invention]

Conventional transmission speed designation devices gradually reduce the transmission capacity of the equipment starting from the highest transmission speed, so even if a line with good line quality and low error rate can be used, the speed will be lowered. This has the disadvantage that it takes a long time to transmit the data, and the purchaser of the equipment has the problem that even though he has purchased a high-speed device, it can only demonstrate its capabilities at low speeds.

This invention was made to solve the above-mentioned problems. When a particular telephone line has a poor line error rate, the bad line can be changed to a telephone number, country code, area code, or % regular carrier. This allows you to specify the transmission speed for some telephone numbers such as connection codes. By specifying the transmission speed depending only on the line quality and efficiently demonstrating the performance of the equipment, you can shorten the transmission time. The object of the present invention is to obtain a transmission speed specifying device that allows the transmission speed to be specified.

[Means to solve the problem]

The transmission speed designation device according to the present invention registers a telephone number with poor line quality or a part thereof, and when the registered telephone number or a part thereof is called, data can be transmitted at the designated transmission speed. This is what I did.

[Effect]

The transmission speed device of this invention can set the transmission speed in advance when registering a telephone number that uses a line with poor line quality and a high error rate, and can also be used on most lines such as international lines. When the maximum speed cannot be used, or when the line quality of the area code depending on the exchange is poor, the transmission speed is divided into groups, and when a telephone number in the above condition or a part of it is called, the transmission speed is Specify a slower speed.
