Description

How to adjust the play level.

The present invention relates to a transmission level adjustment, and more particularly, when communicating with a modem of a terminal device, after calculating and storing an optimized level for each station, the communication level is optimized at the time of communication for each country. It is about a method of automatically adjusting the delivery level to enable.

In the present specification, a multifunction apparatus is described as an example of the terminal apparatus.

In general, a multifunction device, as is well known, is a multi-function terminal that combines existing terminals such as facsimile machines, scanners, printers, and copiers into a single unit. Multi Functional Product (MFP).

When a line is cut by a modem embedded in a conventional MFP, automatic dialing is performed only when it is recognized as a dial tone among a busy tone or a dial tone input through a public switched telephone network (PSTN). Level adjustments were to be sent to the level set on the MFP itself, regardless of dial tone.

Therefore, when communicating in areas where phase delay or amplitude distortion is severe on the line, attenuation may occur severely or phase delay may occur. There was a disadvantage that the phenomenon occurs.

At present, the telephone line power and line current characteristics provided by the exchanges are different in each country, so the data received at the receiving side is not very high, but there are differences.

However, because the data communication is performed by the modem, the data communication may be lost if the signal is shaken or attenuated by a small level difference (e.g. 1 to 2 dB) due to the characteristics of the modem and analog device. In communication, areas where attenuation occurred severely had a disadvantage of having to adjust the level of the terminal directly.

Therefore, the present invention was devised to solve such a problem, and an object of the present invention is to perform a user's dialing by creating a table for each country for a signal transmission level when the communication rate is highest by performing a communication test for each country. In this case, it recognizes the inputted country code (eg, '82' in 001-82-2-796-5705) and transmits the optimal signal level corresponding to the inputted country.

The number detecting unit 223 detects a number for determining whether to use an international call service, from the number generating key of the operation panel 270 or the receiving party number input by automatic dialing.

The database unit 224 previously stores transmission level data optimized for each country.

The level receiver 222 receives the dial tone transmitted from the receiver.

The comparison unit 225 compares the dial tone received by the level receiving unit 222 and the transmission level for each country stored in the database unit 224.

The control unit 221 generates a control signal for setting the delivery level according to the result value compared in the comparison unit 225.

Hereinafter, a method of adjusting the delivery level of the present invention will be described in detail with reference to FIGS. 1 to 4.

First, it is determined whether to perform automatic dialing (step S100).

That is, when the automatic dialing setting unit (not shown) included in the operation panel 270 shown in FIG. 2 is set, automatic dialing is performed to the receiving side (step: S120).

As a result of the determination, when not automatically dialing, a receiving party number is input to set up a call for data transmission / reception (step S110).

The input of the receiving number uses a number generator (not shown) provided in the operation panel 270.

It is determined whether the received receiving party number is for using an international call (step S130).
