Description

Internet connection device of personal computer adopting asymmetric digital subscriber line system

The present invention relates to a personal computer, and more particularly, to an apparatus for connecting a personal computer to the Internet.

In general, in order to receive data services such as the Internet through a personal computer, data services can be received by connecting to the Internet through a dial-up modem or an Ethernet LAN card. However, there was a difficulty in using a telephone when accessing the Internet and receiving data service in the above manner. In addition, the connection method through the Ethernet LAN card had to be provided with a hub and a separate cable.

As described above, a conventional telephone cannot be used to connect to the Internet, and when connecting to an Ethernet LAN card, additional equipment must be provided.

It is therefore an object of the present invention to provide an internet access device for a personal computer employing an asymmetric digital subscriber line system which can use a telephone while connecting to the internet and does not have to provide an additional device.

1 is an Internet connection diagram of a personal computer according to a preferred embodiment of the present invention;

FIG. 2 is a diagram illustrating a data processing process of FIG. 1.

The present invention for achieving the above object is connected to the Internet to transmit and receive data or Ethernet data according to the Internet service provider and the serial line Internet protocol, convert the data into data according to the high-level data link control and add identification information An asymmetric digital subscriber line terminal device for a station for transmitting to a telephone line or retrieving identification information of data received from the telephone line, converting the information into an information form according to the identification information, and transmitting the same to an Internet service provider; Connected to a subscriber line terminal device and a telephone line to transmit and receive information, retrieve the identification information of the received data, convert the information into an information form according to the identification information, and provide it to a personal computer. Data or tooth And a subscriber side asymmetric digital subscriber line terminal device which receives the net data, converts the data into data according to a high level data link control, adds identification information, and transmits the data to the asymmetric digital subscriber line terminal device for the station through a telephone line. It is characterized by.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the annexed drawings, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent to those skilled in the art that the present invention may be practiced without these specific details. And a detailed description of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

A preferred embodiment of the present invention will be described in detail with reference to FIG. 1, which shows an internet connection state diagram of a personal computer according to a preferred embodiment of the present invention, and FIG. The ISP (Internet Service Provider) 10 is an Asymmetric Digital Subscriber Line Terminal Unit-Central Office for connecting stations by Serial Line Internet Protocol (SLIP) data and Ethernet data to the Internet. ATU-C) (12). The ATU-C 12 converts the data into High Level Data Link Control (HDLC) data when the SLIP data is received through the SLIP port, and the identification information for distinguishing the data is included in the header of the HDLC data. Add. The ATU-C 12 converts HDLC data into ADSL data and provides the same to an Asymmetric Digital Subscriber Line Terminal Unit-Remote (hereinafter referred to as ATU-R) 14 connected to a telephone line. do.

The ATU-R 14 receives the ADSL data, converts it into HDLC data, and retrieves identification information of the data. The ATU-R 14 provides the personal computer 16 via the serial interface if the received data corresponds to SLIP data, and provides the personal computer 16 via Ethernet if the received data corresponds to the SLIP data.

When the ATU-R 14 receives data from the serial port of the personal computer 16, the ATU-R 14 converts the data into HDLC data and adds identification information to the header of the data. Then, data is received from the Ethernet port of the personal computer 16, the data is converted into HDLC data, and identification information is added to the header of the data. The ATU-R 14 converts the HDLC data into data for ADSL transmission and provides it to the ATU-C 12.

The ATU-R 12 receives the data, converts the data into HDLC data, reads identification information, and transmits the identification information to the ISP 10 through the Internet according to the SLIP protocol. According to the transmission to the ISP (10) via the Internet.

Since the information is transmitted and received from the Internet through the asymmetric digital subscriber line system, it is possible to use a telephone when transmitting and receiving information. In addition, it is not necessary to provide additional equipment even when using Ethernet as the data is processed as described above.

As described above, the present invention is advantageous in that it is possible to use a telephone when transmitting and receiving information through the Internet, and even when Ethernet is used, no additional equipment is provided.
