Description

Relay Device between Internet and Phone line

The present invention connects the Internet and a telephone that is rapidly increasing in use as a relay device for relaying the Internet and a telephone, and unlike a conventional Internet phone, the apparatus directly connects the user's outgoing call to the Internet such as a dial pad. In addition, there is a UTP port to connect a computer to the Internet line, and to connect to the computer with a UTP cable.

In the prior art, a PC could not be connected to a regular telephone like a dial pad through the Internet, and a general telephone charge was generated through a general telephone network.

The present invention, unlike the existing Internet phone is connected to a relay device that acts as an Internet phone without a PC to make an outgoing call through the Internet network and the incoming call is to be connected through the existing public telephone network.

In addition, it is connected to the Internet network, which also serves as an Internet access device by using a connection terminal with a PC.

Receives a call using a regular telephone line. When sending a call, it transmits through an internet line. It can also be used as an internet relay by connecting a general PC.

The equipment configured for the purpose is a telephone signal control unit for managing the connection of the telephone network, analog to digital convert / digital to analog convert (ADC / DAC) to convert and transmit and restore the telephone signal to the Internet, digital phone It consists of a ROM that contains a program that converts and restores the signal into the TCP / IP protocol of the Internet, a controller that controls the overall operation, and an Internet signal controller that manages the Internet connection of the PC.

The function of each part according to the present invention is as follows.

A telephone network connection unit 10 connected to an external telephone line through a PSTN network, which is a public telephone network, a telephone line connection unit 20 directly connected to a telephone, and a telephone signal controller 30 for distinguishing and connecting external outgoing and incoming calls; Internet line connection unit 40 for connecting to the Internet network, RJ45 PORT 50 for connecting with an internal LAN or PC LAN card, Internet signal control unit 60 for distinguishing whether an outgoing call or an Internet LAN connection, and the whole, Control unit 70 for controlling the operation of the device, ADC / DAC unit 80 for changing the telephone signal and the Internet signal mutually, ROM unit 100 containing a program for connecting to the Internet, Internet dedicated line or cable Internet signal converter 90 to convert the connection signal of the modem and the power supply unit 110 for supplying power to the device.

The present invention is divided into a case of using a telephone and a case of using a PC.

First, when the user uses the telephone, the telephone signal control unit 30 detects the call through the telephone line connection unit 20 and does not BYPASS the telephone number the user presses to the converter which is the ADC / DAC unit 80. The program executed in the 100 is converted into a data format that can be transmitted to the Internet in the TCP / IP protocol under the control of the control unit 70, and the converted data is an Internet signal converter connected to the outside through the Internet signal control unit 60. The Internet signal converter 90 converts the data into a form suitable for an Internet dedicated line or a cable modem and transmits the data to the Internet line connection unit 40 so that the data is sent to a corresponding telephone station or Internet server through an external network. When data is received, it is transmitted through the opposite case and is omitted.

When an incoming call comes through a general telephone network, the telephone network controller detects a signal of the telephone network connection unit 10 and sends a telephone signal to the telephone line connection unit BYPASS.

In the case of using a PC, data is transmitted to the RJ-45 port 50 through the LAN cable connected to the LAN card of the PC, and the Internet signal controller 60 bypasses the data to the outside through the Internet signal converter 90. Data sent and received is sent via the reverse.

Internet telephony PC relay device having an Internet phone function according to the present invention can make the ordinary phone to be an Internet phone without a PC and can be connected to the Internet through a PC to reduce the phone costs for the user.
