Abstract

PURPOSE:To automatically determine a MODEM output level by discriminating the installation district of an originating station from an inputted selection signal, setting up a transmission output level corresponding to the district and executing communication processing. CONSTITUTION:A memory 7 consisting of an SRAM to be used for storing telephone book data, a RAM to be used as a work area and a ROM for storing a control program is connected to a CPU 6. A user previously registers terminating subscriber's names and FAX numbers in a telephone book memory in the memory 7. In the case of selecting a certain terminating station in the telephone book memory by an abbreviated dialing or an one-touch key on a keyboard 8 and transmitting data, whether the data are to be transmitted to a foreign country or not and whether its country number indicates a foreign country requiring the change of a MODEM output or not are discriminated based upon the FAX number as the preprocessing of the transmission. When the change of the MODEM output is required, the sending level of the MODEM is changed, and in the case of no change, data are directly transmitted without changing it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device, and particularly to a communication device that performs communication using a predetermined method with a partner station having a selection number input by a user.

[Prior Art] Conventionally, in facsimile machines, when sending overseas, it is sometimes necessary to change the output level of the modem in order to compensate for signal attenuation caused by the line conditions of the destination and the distance of transmission. .

Conventionally, this change has been made by the user or service personnel based on the error code after transmission.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, in order to deal with errors due to the modem's transmission level, there is a disadvantage in that the level must be changed for each transmission.

An object of the present invention is to solve the above problems and provide a communication device that can automatically determine the modem output level.

[Means for Solving the Problems] In order to solve the above problems, in the present invention, in a communication device that performs communication in a predetermined manner with a partner station having a selection number input by a user, The control means is configured to identify the installation area of the other station from the number, set the transmission output level according to the installation area, and perform communication processing.

[Operation] According to the above configuration, an appropriate signal transmission output level can be automatically set according to the installation area of the partner station.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 shows the structure of a facsimile machine adopting the present invention.

The facsimile machine shown in FIG. 1 is constructed by connecting the following components to a CPU 6 consisting of a microprocessor or the like.

First, the NCU (Network Control Unit) (2) performs line control such as sending out dialing signals and detecting incoming calls.

A handset 2 is connected to the NCU 1, which is used by an operator to make a call or make a conversation.

The modem 3 inputs and outputs transmission and reception signals to and from the line IO via the NCU 1. In this case, the modem 3 transmits and receives facsimile procedure signals and image signals through modulation and demodulation.

The reading device 4 includes a CCD line sensor, a document conveyance system, and the like, and is used to read document images.

The printer 5 includes a thermal recording head, a recording paper transport system, and the like, and is used to record received images or images read by the reading device 4 when copying originals.

A keyboard 8 and a display device 9 are for a user interface, and the keyboard 8 is composed of a numeric keypad, function keys, and the like, and is used for inputting the telephone number of the other party.

On the other hand, the display device 9 is composed of an LCD display or the like, and is used to display the current time, operating status, etc.

The CPU 6 includes S, which is used for storing telephone directory data.
A memory 7 consisting of a RAM, a RAM used as a work area, a ROM that stores a control program to be described later, etc.
is connected.

In the facsimile machine shown in FIG. 1, the user registers the name and fax number of the other party in the telephone directory memory in the memory T in advance, and dials the other party's station in the telephone directory memory by speed dialing or using one-touch keys on the keyboard 8. When sending by selecting the fax number, as a pre-transmission process, you can check whether the fax number is to be sent to a foreign country or not, and the country whose country code requires changing the modem output (for example, in the example below, Spain is this foreign country). ).
If so, change the modem's transmission level; otherwise, transmit without changing it.

For example, assume that the telephone number of the other station is registered in the telephone directory memory in the memory 7 in a table format as shown in FIG.

As shown in the figure, the telephone directory memory contains the name of the other party, the fax number,
Data is registered in numerical order. Here, registration data of two partner stations is shown.

FIG. 3 shows the control procedure of the CPU 6 in FIG. 1 during transmission. The procedure shown in FIG. 3 is performed when the user selects the desired destination station by operating the keyboard 8 after loading a document into the reading device 4 or reading image data into the image memory in the memory 7. It will be held in

This destination selection is performed by speed dialing or one-touch key operation on the keyboard 8.

The registered data of each partner station in FIG. 2 is in one-to-l correspondence with these operations, and it is identified to which partner station in FIG. 2 the transmission is to be made in accordance with the operation.

In step Sl in FIG. 3, it is determined whether the first three characters of the selected FAX number are 001 (whether it is an international call or not), and if so, the process proceeds to step S2; otherwise, the process proceeds to step S4. .

In step S2, it is determined whether the next two characters are 39 (Spanish or not), and if so, the process proceeds to step S3; otherwise, the process proceeds to step S4.

In step S3, the output level of the modem 3 is changed. In step S4, normal transmission is performed. In this way, the number of errors during transmission can be reduced (assuming that the number of errors caused by the transmission level of the modem 3 is large when transmitting to Spain).

According to the above embodiment, if the fax number of the other party indicates overseas transmission and furthermore, the transmission is to a specific foreign country,
Since the transmission level of the modem 3 can be adjusted as appropriate, transmission can be ensured successfully without communication errors, and there is no need for troublesome output level adjustment operations.

In the following, the modem output is adjusted when a specific country is identified based on the fax number, but the output level is not limited to overseas transmissions, and even domestic communications can be adjusted. If you know the area where you should adjust the
The modem output may be adjusted by identifying the area code of this area.

In addition, whether or not modem output adjustment is necessary is determined at predetermined intervals during communication with a partner station in a predetermined area identified by a predetermined station number in the past communication result record stored in the memory 7. By referring to the error number that occurred, it may be determined whether modem output adjustment is necessary for transmission to that area. Alternatively, the user may manually enter in advance from the keyboard 8 the FAX number for which the user wishes to adjust the modem output.

In addition, although the above example shows an example in which the destination station is selected using speed dialing or one-touch keys, the same effect can be expected even when selecting the destination station by manual input by identifying the input fax number. can. In addition, adjusting the modem output not only for transmission but also for reception has the effect of ensuring the transmission of the procedure signal, so it is not meaningful to perform this kind of processing even during pawning etc. be.

Although a facsimile machine has been exemplified above, it goes without saying that a similar configuration can be implemented in other communication devices. In that case, the FAX number may be treated as a selection number of the format used by the communication device.

[Effects of the Invention] As is clear from the above, according to the present invention, in a communication device that performs communication in a predetermined manner with a partner station having a selection number input by a user, it is possible to detect the partner station based on the input selection number. The configuration includes a control means that identifies the installation area, sets the signal transmission output level according to the installation area, and performs communication processing, so the signal transmission output can be adjusted appropriately depending on the installation area of the other station. This method has the excellent effect of automatically setting the level, eliminating the need for troublesome operations, and ensuring successful communication processing.
