Abstract

PURPOSE:To attain the data transmission by the best condition by setting the data transmission characteristic based on the utility data and applying data transmission to an opposite station connected based on the set data transmission characteristic. CONSTITUTION:A call circuit 10 based on a dial operation of a telephone set outputs a telephone number to a telephone line 40. A detection circuit 50 outputs a preset data corresponding to the inputted telephone number in advance as an address when the call circuit 10 outputs a telephone number. In receiving an address from a detection circuit 50, the setting storage circuit 20 outputs a control data written in advance corresponding to the said address. A data transmission circuit 30 inputs a control data from a setting storage circuit 20, sets the frequency characteristic or the like based on the inputted control data and applies data transmission to the connected opposite exchange via the telephone line 40.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data transmission device that dials a partner station and, after connection, performs data transmission.

[Conventional technology]

Conventionally, this type of data transmission device has a calling circuit 1 which outputs a telephone number for selecting a partner station, as shown in FIG.
0, and a data transmission circuit 30 that performs data transmission with the other party via the telephone line 40 after the calling circuit 10 outputs the telephone number.
and a setting storage circuit 21 that holds control data related to the telephone line 40 and the like necessary when the data transmission circuit 30 performs data transmission and supplies it to the data transmission circuit 30.

The data transmission circuit 30 includes an equalizer for correcting frequency characteristics corresponding to the telephone line 40, and a self- and other-party data transmission [?
It has a timer that sets the response time to lfi, a received signal level setting unit that sets the signal level received from the data transmission device of the other station, etc. Settings are made based on control data to ensure good performance.

These control data are manually set in the setting section 1 circuit 21 each time the destination station is dialed, either by connecting a locking device to the setting storage circuit 21 or by operating a switch provided in the setting storage circuit 21. I had to.

[Problem that the invention seeks to solve]

Conventional data transmission as mentioned above! AW1 requires setting of control data each time data is transmitted, and this setting requires highly specialized technology, so the number of users is limited and general users cannot master it, so it is not suitable for general use. However, the disadvantage is that the desired data transmission cannot be carried out using the conventional method.

(Means for Solving the Problem) The data transmission device of the present invention includes: a calling circuit that outputs a dial number for connecting to a partner station via a telephone line; and a calling circuit that outputs the dial number. There is a detection circuit that detects the dial number and outputs a pre-written address corresponding to the detected dial number, and a detection circuit that inputs the address output by the detection circuit and stores it in advance corresponding to the input address. It has a setting storage circuit that outputs control data, and a data transmission circuit that sets data transmission characteristics based on the control data and performs data transmission with a connected partner station based on the set data transmission characteristics.

[Effect]

By simply dialing a telephone number, control data corresponding to the dialed number is output from the setting storage circuit to the data transmission circuit, so even ordinary people without specialized skills can transmit data in the best possible condition. can.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a data transmission device of the present invention.

The calling circuit 10 outputs a telephone number to the telephone line 40 based on the dialing operation of the telephone a (not shown).

When the detection circuit 50 detects that the calling circuit 10 has output a telephone number, it outputs data set in advance corresponding to the input telephone number as an address. When the setting storage circuit 20 receives an address from the detection circuit 50, it outputs control data written in advance in accordance with the address. The data transmission circuit 30 inputs control data from the setting storage circuit 20, sets frequency characteristics, timer, received signal level, etc. based on the input control data.
Data transmission is performed via the telephone line 40 with the connected partner station.

Therefore, this data transmission is executed under the best conditions set in advance for each partner station number.

〔Effect of the invention〕

As explained above, the present invention writes an address to be output corresponding to a dialed number to be called into a detection circuit, and inputs and outputs control data in advance to a setting storage circuit in accordance with an address output by the detection circuit. , departure j'! By outputting the control data corresponding to the dialed number to the data transmission circuit, the data transmission circuit can be operated in the best possible condition, so even people without specialized skills can easily perform high-quality data transmission. There is an effect that can be done.
