Abstract

The present invention relates to a multi-channel provision system for a wired network. The multi-channel provision system of the present invention includes a tap-off unit (330) for dividing a frequency band, assigned to a wired network for network communication, and providing resultant frequency bands to respective subscriber units belonging thereto. An optical network device (100) is disposed at a node where one or more sectors, divided according to a number of subscriber units that enable network access through the wired network, branch off. The optical network device (100) provides a frequency band for network access to each sector so that a same frequency band is assigned to each sector, thus generating a multi-channel for the frequency band, and reusing the frequency band, assigned to the wired network, a number of times corresponding to the number of the sectors through generation of the multi-channel.

Claims

1. A multi-channel provision system for a wired network, comprising:

a tap-off unit for dividing a frequency band, assigned to a wired network for network communication, and providing resultant frequency bands to respective subscriber units belonging thereto;

an optical network device disposed at a node where one or more sectors, divided according to a number of subscriber units that enable network access through the wired network, branch off, the optical network device providing a frequency band for network access to each sector so that a same frequency band is assigned to each sector, thus generating a multi-channel for the frequency band, and reusing the frequency band, assigned to the wired network, a number of times corresponding to the number of the sectors through generation of the multi-channel; and

at least one repeater disposed between the optical network device and each of the subscriber units, the repeater amplifying intensity of network packet signals, thus increasing possible communication distance between the optical network device and the subscriber unit.

2. The multi-channel provision system according to claim 1, further comprising a splitter constructed so that, when two or more sectors correspond to the frequency band assigned to a single wired network in the optical network device, the splitter is disposed between the two or more sectors and the optical network device and is adapted to distribute the frequency band assigned by the optical network device according to the number of sectors and to assign distributed frequency bands to the two or more sectors.

3. The multi-channel provision system according to claim 1, further comprising an Ethernet Coaxial Bridge (ECB) constructed so that, when the subscriber unit is connected to the network through an x Digital Subscriber Line (xDSL) modem, the ECB is disposed between the tap-off unit and the xDSL modem and is adapted to process signal conversion between the xDSL modem and the tap-off unit.

4. The multi-channel provision system according to claim 1, wherein each of the subscriber units is one of a Voice over Internet Protocol (VoIP) modem, a cable modem, and an xDSL modem.

5. The multi-channel provision system according to claim 1, further comprising an Access Point (AC) disposed between the tap-off unit and a wireless communication device and adapted to perform wireless communication with the wireless communication device.

6. The multi-channel provision system according to claim 1, wherein the optical network device comprises:

at least one channel card mounted on a motherboard having a bus, and adapted to provide the same frequency band to each sector, thus generating the multi-channel for the frequency band; and

a media converter for processing signal conversion between an optical network and the motherboard.

7. The multi-channel provision system according to claim 6, wherein the optical network device assigns the same frequency band that is assigned to any one of subscriber units belonging to each sector, to any one of subscriber units belonging to another sector.

8. The multi-channel provision system according to claim 6, wherein the channel card is provided such that a number of channel cards corresponding to the number of sectors is provided in the motherboard.

9. The multi-channel provision system according to claim 6, wherein the channel card is provided such that at least two channel cards correspond to any one of the sectors and the frequency band is divided according to the number of channel cards.

10. The multi-channel provision system according to claim 9, further comprising a channel control unit for arranging a subscriber unit in any one of channel cards corresponding to a sector to which the subscriber unit belongs, when a communication channel access request is generated by the subscriber unit.

11. The multi-channel provision system according to claim 10, wherein the channel control unit is operated such that, when a communication channel access request is generated by the subscriber unit, the channel control unit makes the subscriber unit correspond to any one of channel cards corresponding to a sector, to which the subscriber unit belongs, channel connection being sequentially performed for the channel cards.

12. The multi-channel provision system according to claim 10, wherein the channel control unit is operated such that, when a communication channel access request is generated by the subscriber unit, the channel control unit makes the subscriber unit correspond to a channel card having a smallest number of channels formed with subscriber units, among channel cards corresponding to a sector to which the subscriber unit belongs.

13. The multi-channel provision system according to claim 10, further comprising a filter connected to an output terminal of at least one channel card corresponding to the sector and adapted to pass therethrough only a frequency band assigned to the channel card.

14. The multi-channel provision system according to claim 6, wherein the channel card comprises:

a diplexer for separating a frequency band, which is assigned to Internet communication, and a frequency band, which is assigned to broadcast signals, from the frequency band assigned to the sector;

a Radio Frequency (RF) unit for performing RF communication with the sector according to the frequency band assigned by the diplexer for the Internet communication; and

a bus interface unit for performing data communication with the media converter through the bus of the motherboard.
