The invention is realized by a device constructed as shown in FIG. The Internet phone connection device 100 is basically and essentially micom 101, ROM 102, RAM 103, splitter 105, selector 106, A / D, D / A converter 107, And a telephone interface 108 and a modem 109, which are connected to the ADSL line 104.

In addition, the computer interface 110 may be mounted on the modem 109 to communicate with the computer.

The Internet telephone connection device 100 configured as described above distributes the signal received through the ADSL line 104 to the selector 106 and the modem 109 through the splitter 105, and the signal received by the selector 106 is general. In the case of a telephone signal, the signal is transmitted directly to the telephone interface 108 without passing through the A / D and D / A converters 107, and the received signal is a signal coming from the Internet network or the ATM backbone network instead of the general telephone signal. Is converted into an analog signal by the A / D and D / A converter 107 and transmitted to the telephone interface 108. The selector 106 and the A / D and D / A converter 107 are controlled by the microcomputer 101.

On the contrary, when making a call, a signal is sent to the selector 106 through the telephone interface 108 and converted into an appropriate signal by the converter 107 through the selector 106, and then again to the ADSL through the splitter 105. A signal is sent out to line 104.

The ROM 102 may use a general EP-ROM, the RAM 103 may use a general D-RAM, and the ROM 102 and the RAM 103 may be used to perform an Internet telephone connection method according to the present invention. In order to process the data stored in order to be used in conjunction with the microcomputer (101).

The Internet telephony connection device 100 configured as described above performs the Internet telephony connection method according to the present invention in the same manner as the flowcharts shown in FIGS. 2A and 2B. Such a method is slightly different between receiving a call and making a phone call, all of which are controlled by the Internet telephony connection device 100.

First, when a call is received as shown in FIG. 3A, the method of connecting an Internet phone detects a signal of an incoming call in the first step (S1).

In the second step S2, it is checked whether the incoming call signal is a normal phone signal. In the case of a general telephone signal, a signal is sent directly to the telephone interface 108 without passing through the AD / DA converter 107 to the telephone connection step S6 to connect a telephone to enable a telephone call. This step is a phone call step S7.

When the signal received in the determination step S2 is not a general telephone signal, that is, a signal coming from the Internet network or the ATM backbone network, the signal is transmitted to the AD / DA converter 107 to convert the signal. This step is the converter operating step S3. In the telephone call step S4, the signal thus converted is sent to the telephone interface 108, and the telephone is connected by the interface 108 to enable telephone conversation.

The next step is to determine whether such a call is ongoing (S5), if the telephone call is continued, continuously transmits a signal to the converter operating step (S3) to continue the above steps and the telephone call is terminated when all Finish the steps

In the case of making a telephone call, the Internet telephone connection method according to the present invention is performed in the same manner as in FIG. 3B.

In step S11, when the user first makes a call, in step S12, it is determined whether or not the call is a regular phone. By the telephone connection step (S19), the user makes a call in the phone call step (S20) and ends immediately after the call.

If the signal received in the call determination step (S12) is not a normal phone, the signal is sent to step S13 to determine whether it is an Internet phone again, and in the case of the Internet phone determination step (S13), the Internet network. Send the signal to the converter operating step (S16) through the connecting step (S15), and if it is not the Internet phone, send the signal to the step (S14) to call the modem through the ATM network to the signal to the converter operating step (S16) Send the.

Similar to the subsequent process of the converter operating step S3 shown in the flowchart of FIG. 3A, the converted signal is converted into the telephone interface 108 in the telephone call step S17 via the signal converted by the converter operating step S16. And the telephone is connected by this interface 108 to enable telephone conversation.

The next step is to determine whether such a call is ongoing (S18), if the phone call is continued, continuously transmits a signal to the converter operation step (S16) to continue the above steps and the telephone call is terminated when all Finish the steps

By doing this, the telephone can be used to connect to the Internet through the ADSL network.
