Abstract

Disclosed is a home gateway apparatus having an in-home telephone network switching function, and an embodiment method thereof. The home gateway apparatus offers high-speed access to an access network using xDSL (“x” variety of Digital Subscriber Line) protocols such as ADSL or VDSL and an in-home network using VoIP (Voice over Internet Protocol) functions and a variety of protocols, and has xDSL and VoIP interfaces with PSTN (Public Switching Telephone Network) and VoIP functions that enable easy installation and application in different in-home telephone network environments. Using this, in-home VoIP/POTS (Plain Old Telephone Service) networks and high-speed HomePNA networks can be freely constructed through a single home gateway, bypassing the existing two-wire or four-wire in-home telephone lines.

Claims

1. A home gateway apparatus, which provides a connection of an in-home network to an access network to offer a variety of services in an integrated network, the home gateway apparatus comprising:

an XDSL (“

x”

variety of Digital Subscriber Line) central processor for providing access to the access network through a first connector, and processing a signal communicated with the connected access network;

a HomePNA (Home Phoneline Networking Alliance) processor for providing HomePNA access to the in-home network through the first connector, and processing a HomePNA signal communicated with the connected in-home network;

a VoIP (Voice over Internet Protocol) processor for providing POTS (Plain Old Telephone Service)/VoIP access to the in-home network through the first connector, and processing a POTS/VoIP signal communicated with the connected in-home network; and

a telephone line switching processor for connecting at least one PSTN (Public Switching Telephone Network) channel transferred from the XDSL central processor to the HomePNA processor and the VoIP processor.

2. The home gateway apparatus as claimed in claim 1, wherein the xDSL central processor provides access to a two-wire and four-wire access networks.

3. The home gateway apparatus as claimed in claim 2, wherein the XDSL central processor uses high-pass and low-pass filters to separate XDSL and PSTN signals received from the connected two-wire and four-wire access networks, and sends the separated signals to an xDSL auxiliary processor and the telephone line switching processor.

4. The home gateway apparatus as claimed in claim 2, wherein the telephone line switching processor is connected using a medium according to a change of the connected in-home network, and is changeable in setting by a user'"'"'s simple manipulation of switches.

5. The home gateway apparatus as claimed in claim 4, wherein the medium includes a relay and a jumper wire.

6. The home gateway apparatus as claimed in claim 1, wherein the HomePNA processor and the VoIP processor are connected to the in-home network using second and third connectors.

7. An embodiment method for a home gateway apparatus, which provides a connection of an in-home network to an access network to offer a variety of services in an integrated network, the embodiment method comprising:

(a) providing access to a two-wire and four-wire access networks through a first connector, and processing a signal communicated with the connected access network;

(b) providing HomePNA access to the in-home network through the first connector, and processing a HomePNA signal communicated with the connected in-home network;

(c) providing POTS/VoIP access to the in-home network through the first connector, and processing a POTS/VoIP signal communicated with the connected in-home network; and

(d) connecting at least one PSTN channel transferred from the connected access network to a HomePNA processor processing the HomePNA signal and a VoIP processor processing the POTS/VoIP signal communicated with the connected in-home network.

8. The embodiment method as claimed in claim 7, wherein (a) comprises:

separating XDSL and PSTN signals received from the connected two-wire and four-wire access networks using high-pass and low-pass filters.

9. The embodiment method as claimed in claim 7, wherein (b) and (c) comprise:

providing access to the in-home network using second and third connectors.

10. The embodiment method as claimed in claim 7, wherein (d) comprises:

providing a connection using a medium including a relay and a jumper wire according to a change of the connected in-home network; and

allowing a user to change the setting by a simple manipulation of switches.

11. A recording medium with a built-in program, which includes an embodiment method for a home gateway apparatus providing a connection of an in-home network to an access network to offer a variety of services in an integrated network, the program comprising:

providing access to the access network through a first connector, and processing a signal communicated with the connected access network;

providing HomePNA access to the in-home network through the first connector, and processing a HomePNA signal communicated with the connected in-home network;

providing POTS/VoIP access to the in-home network through the first connector, and processing a POTS/VoIP signal communicated with the connected in-home network; and

connecting at least one PSTN channel transferred from the connected access network to a HomePNA processor processing the HomePNA signal and a VoIP processor processing the POTS/VoIP signal communicated with the connected in-home network.
