Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an internet connection system, and more particularly to an internet connection system using a telephone line.

[0002]

2. Description of the Related Art In order to connect computers to each other,
Connect them both fixedly with a high-speed leased line, or connect a modem to an analog telephone line to convert them into voice, or connect a terminal adapter (TA) to the ISDN line to call and connect them when necessary. Was there.

In the case of a dedicated line, a relatively high-speed line can be prepared because the connection route is selected according to the transmission speed and fixed connection is made, but the fee is extremely expensive because the fixed connection line is occupied. Become.

Further, when an analog telephone line or ISDN line is used, the usage fee is the same as the telephone call fee because it goes through an exchange, so that a long-time connection is expensive.

Further, it is difficult to perform high-speed communication because an exchange in the telephone network or a connecting relay line in the middle is not optimally selected for high-speed data communication. With the current technology, 28 Kbps for analog per call and 64 Kbps for ISDN. Is the upper limit.

For connection to the Internet using a conventional analog telephone, the configuration shown in FIG. 3 is generally adopted.

That is, FIG. 3 is a connection diagram to the Internet using a conventional analog telephone, and in the figure, reference numeral AA
3, BB3 is a telephone exchange of a telephone exchange office, C3 is an internet provider, Cm3, Xm3 are modems, Cp3 is an internet connection computer, Cr3 is an internet connection control device, X3 is a telephone subscriber's house, Xa3, Ca.
3 is an analog telephone line, Xd3 is an analog telephone, Xp
3 is a computer.

An Internet connection using the conventional analog telephone shown in FIG. 3 will be described. Analog telephone line Xa3 installed in telephone exchange AA3 and telephone subscriber's house X3 in the telephone exchange by analog telephone line Xa3
The personal computer Xp3 is connected via d3 and the modem Xm3.

On the other hand, a telephone exchange BB3 in the nearest telephone exchange office is connected to a computer Cp3 installed in an internet providing company C3 via a modem Cm3 and an analog telephone line Ca3. Computer Cp
3 is connected to the Internet via the connection control device Cr3.

The telephone exchange AA3 and the telephone exchange BB3 are connected by a telephone network (relay exchange) to form a telephone network.

In order to connect to the Internet from the personal computer Xp3 of the telephone subscriber's house X3, modems up to the modem Cm3 in the Internet provider C3 that has a contract for Internet connection (dial IP connection) via the analog telephone lines Xa3 and Ca3. Make a phone connection using Xm3. At this time, the data signal necessary for communication is converted into an analog voice signal by the modem Xm3, enters the modem Cm3 owned by the internet connection company C3 through the telephone network, is demodulated into a data signal, and is connected to the computer Cp3. It After that, the computer Xp3 of the telephone subscriber's house X3 and the computer Cp3 of the internet provider company C3 communicate with each other to access the internet through the internet connection control device Cr3 connected to the computer Cp3.

[0012] At this time, the cost for connecting to the Internet is from the telephone subscriber's house X3 to the Internet providing company C3.
The telephone charge up to and the usage fee of the computer Cp3.

[0013]

The above-mentioned conventional connection form to the Internet has the following problems.

The first problem is that the procedure for connecting devices and connecting to the Internet is complicated, and the charges are high.

That is, the analog line and ISD of the current telephone
When using the N line, connect to the telephone line via a connection device such as a modem or terminal adapter when using a home computer, and then use the telephone line to call the connection point of the target Internet provider. However, it is necessary to use a predetermined command to enter the computer for connecting to the Internet, and the connection of the device and the connection procedure become very complicated and time-consuming. Also, the telephone charge during the communication and the computer connection charge of the internet connection company have to be paid separately, which becomes very expensive when the connection is long distance.

The second point is that communication cannot be performed at high speed.

That is, high-speed data can be passed through the telephone line installed in the home or the telephone line laid from the home to the telephone exchange office (up to 10 Mbps), but when it comes to the telephone system, the telephone exchange and relay are provided. There are many things such as line concentrators and wireless transmission devices that interfere with high-speed data communication.
8Kbps, ISDN 64Kbps is the upper limit,
Inefficient for internet connection that requires high speed data communication.

In view of the above problems of the prior art, it is an object of the present invention to provide an internet connection system using a telephone line, which can improve dryness and cost, and can also speed up.

[0019]

According to the internet connection system using a telephone line of the present invention, a computer and a telephone are connected to the telephone line via an internet connection device in the internet connection system using a telephone line. In the telephone exchange office, this wiring board is connected to the telephone exchange and the internet concentrator, the internet concentrator is connected to the internet connection computer via the telephone line, and the internet connection computer is connected to the internet via the internet connection control device. The computer is connected to the Internet via the main wiring board by setting the incoming call restriction on the telephone exchange side using the telephone.

The Internet connection system using the telephone line of the present invention is the Internet connection system using the telephone line, in which the computer and the telephone are connected to the telephone line through the Internet connection device and the book is set in the telephone exchange office. The wiring board is connected to the telephone exchange and the internet concentrator, the internet concentrator is connected to the internet connection control device via the telephone line, the internet connection control device is connected to the internet, and the telephone exchange side is used by using the telephone. By setting the incoming call restriction on, the computer is connected to the Internet via this wiring board.

That is, when the telephone is not used from the computer in the home of the telephone subscriber connected to the telephone line,
You can connect to the Internet with fewer connections using only telephone lines.

Therefore, it is possible to set a charge that is not tied to the telephone charge.

Further, since the telephone exchange station to which the telephone is subscribed can directly connect to the Internet, it can be used at a low cost even if there is no connection point of the Internet provider company near the user.
