The present invention relates to a circuit automatic selection apparatus using an ID card that compares data and generates DTMF in a telephone network of a corresponding country.

Due to the development of information and communication technology, the sound quality of the telephone becomes clearer, call waiting time is shortened, and enormous amount of call processing is possible. In addition, due to competition among telecommunication companies, advanced technologies and various convenient services are provided. In line with this, telephone cards, which were initially used only for public phones, have been developed in various ways depending on their purpose of use, payment method, and functions.

Among them, discount telephone services are provided that can be used for low-cost phone calls. Discounted telephone service means that if you make a local, long-distance or international call, you can connect to the communication network provided by the telecommunication service providers and call them according to the contracted discount rate. It is to give discount.

Most telephones are connected to the main telecommunication network provided by Korea Telecom, so if you use the telephone, you will pay the telecommunication fee to the telecommunications provider KT.

However, even if the telephone is connected to the main telecommunication network of Korea Telecom, discount telephone service is possible.

Therefore, in order to solve this inconvenience, separate service providers have to provide an auto calling router (ACR) to automatically dial the service provider's access number, PIN number, and telephone number of the counterpart country. People who use it can use it like a regular phone because it automatically selects a line by pressing a hot key without dialing the operator's access number, PIN number and phone number of the other country.

However, in case of using such a conventional automatic line selection device for international calls, in most cases, the telephone system of the other country is different. In this case, the telephone number stored in the automatic line selection device is transferred to the other country by DTMF to the other country. Due to the difference in the telephone system of the other country, there is a problem in that the telephone network of the other country does not recognize the DTMF transmitted from the line automatic selection device and thus cannot be connected or incorrectly recognizes and connects to another number.

The present invention is to solve the above problems, by using the ID card to check the country code included in the phone number from the ID card and the telephone number is the same as the DTMF of the other country's telephone network, DTMF duration and duty ratio The purpose of the present invention is to provide an automatic line selection device using an ID card that controls the tone-pulse to generate DTMF that is appropriate for the country's telephone network, thereby preventing malfunctions and errors caused by differences in the telephone network system between countries.
