The present invention relates to a wired telephone sharing apparatus, and more particularly, is provided between a wired telephone line of a public switched telephone network (PSTN) network and an internet network and is connected to a PSTN network from a remote personal computer (PC) connected to the Internet network. The present invention relates to a wired telephone sharing device that allows a wired telephone such as a home or an office to communicate with another subscriber's wired telephone through a wired telephone sharing device.

The PSTN network for analog phones has a long history and has been widely deployed all over the world, and users of existing landline phones still make most of their voice calls using the PSTN network.

Voice calls using the PSTN network have advanced call quality, more subscribers, and security than voice calls implemented on Internet phones (VoIP phones). However, voice calls are relatively expensive and places where wired telephones are located. In other regions, it is difficult to make a call and the incoming call can be made by paying a separate service fee.

An object of the present invention is to allow incoming and outgoing calls from a landline telephone connected to a PSTN network to be made from a PC connected to the Internet regardless of the place where the landline telephone is installed. Its purpose is to provide a wired telephone sharing device that allows each user to share and use the PC in different places.

The present invention for achieving the above object, PSTN network interface unit for transmitting and receiving voice data through the PSTN connection port and processing the control signal of the control and conversion unit in accordance with the voice data transmission and reception protocol used in the PSTN network;

An internet network interface unit for transmitting and receiving voice data through an internet access port and processing a control signal of a control unit and a conversion unit in accordance with a protocol for transmitting and receiving voice data with a PC of an internet network;

Characterized in that it comprises a control and conversion unit for converting the voice data of the PSTN network and the voice data of the Internet network to the appropriate voice data and the control of the wired telephone sharing device to match the other network.

Hereinafter, with reference to the accompanying drawings, the configuration of the invention in detail as follows.

1 is a system configuration of a wired telephone sharing apparatus according to the present invention is applied.

PC (20, 21) installed with a voice call program for transmitting and receiving voice data with the wired telephone sharing device 30 is connected to the Internet network 10, PSTN network 40 is used to make a voice call General landline phone 1 (50) of the office or home and the common landline phone 2 (60) coupled to the wired telephone sharing device 30 is connected. In addition, a wired telephone sharing device 30 for converting signals and voice data to match the heterogeneous manganese is connected to the Internet network 10 and the PSTN network 40.

Meanwhile, although the wired telephone sharing apparatus 30 of the present invention is described as an external device separately connected to the wired telephone 2 60 in FIG. 1, the wired telephone sharing apparatus 30 may be implemented as a device in the form of a telephone combined with the wired telephone 2 60. have.

The PCs 20 and 21 log in to the wired telephone sharing device 30 through the Internet network 10 and receive a connection permission for sharing the wired telephone 2 60.

In general, if you make a call from a landline phone 1 (50) to a landline phone 2 (60), the bell rings at the landline phone 2 (60) and at the same time the wired phone sharing device 30 receives the incoming signal to the Internet network (10). Sends an incoming call to the logged-in PC (20, 21) through).

Among the PCs 20 and 21 that receive the incoming signal, the landline phone sharing apparatus 30 controls the call so as to make a call to the PC that has accepted the incoming call to form a call line with the landline 1.

The PCs 20 and 21 may also set whether to allow incoming calls when logging in.

The logged-in PC (20, 21) is able to make a call to the landline phone 1 (50) by running a voice call program, the logged-in PC (20, 21) is a landline phone to the current state of the landline phone 2 (60) Received from the sharing device 30, the landline phone 2 (60) is available when the state can be used, the PC to be sent to the wired telephone sharing device 30 to send the telephone number of the called party, the wired telephone sharing The device 30 sends an outgoing signal to the telephone station switch to form a call line with the landline 1.

The target of the telephone that can be dialed can be dialed not only for the wired telephone 1 50 in the PSTN network 40 but also for all the telephones for which the wired telephone 2 60 can make a call.

2 is a block diagram of a wired telephone sharing apparatus according to the present invention,

As shown in the drawing, the Internet connection port 31 and the PSTN connection port 32 are physically connected to each communication line, and serve as a passage for transmitting and receiving signals and voice data with each communication line.

The internet network interface unit 34 is connected to the internet network 10 to perform a data communication function in accordance with a protocol used in the network, and supports a protocol required for communication with voice call programs installed in the PCs 20 and 21. . In addition, voice data input and output between the Internet access port 31 and the PSTN network interface unit 35 is performed, and data generated during the process is converted into an appropriate format.

The PSTN network interface 35 performs DTMF (Dual Tone Multi Frequency) generation, ring detection, and on / off hook control functions for connecting to the PSTN network 40, and the PSTN connection port 32 and the Internet network interface unit ( 34) Performs input and output of voice data, converting data generated during the process into an appropriate format.

When the voice data generated in the PSTN network 40 and the Internet network 10 is transmitted to the other party through the PSTN network interface 35 and the Internet network interface 34, When the voice data is converted to match the other side network and the control signal and the control data generated from the PSTN network interface unit 35 and the Internet network interface unit 34 are detected, the control unit performs the above control. Command to output the signal.

According to the present invention as described above, by controlling the incoming and outgoing calls from the landline telephone installed in the home or office from multiple PCs, it is possible to share one landline telephone with multiple PCs. Therefore, the efficiency of the landline phone is increased, and even where it is difficult to install the landline phone, there is an effect that the landline phone can be used without any restrictions on the place. In particular, when a landline telephone is shared and used at a remote location such as a local or a foreign country, the call fee can be saved.
