Abstract
Description
- The present invention relates to a power line communication (PLC) system which includes a PLC Digital Subscriber Line Access Multiplexer (DSLAM) and a PLC coupling device, and a communication device used in the PLC system. More particularly, the present invention relates to a PLC system where a data signal is received from an Internet Protocol (IP) network via a PLC DSLAM, which is generally installed in a telephone office, the received data signal is converted into a PLC frame signal according to a predetermined PLC protocol, and the converted PLC frame signal is transmitted to at least one subscriber location via a telephone line, and a PLC coupling device of the subscriber location receives the PLC frame signal via the telephone line, couples the PLC frame signal with a power line, and transmits the coupled PLC frame signal to at least one communication terminal, and a communication device used in the PLC system.
- A power line communication (PLC) indicates a communication method which transmits/receives a data signal via a power line, wired in a house or an office to supply power. Specifically, the PLC may be embodied by modulating a data signal into a high frequency signal, transmitting the modulated high frequency signal to an alternating current (AC) line, and separating and receiving the transmitted high frequency signal via a high frequency filter. In this instance, the high frequency filter has a cutoff frequency of about 50 Hz or about 60 Hz.
- Since a network utilizing PLC technology can be constructed utilizing an existing wiring, a cost burden, which may be caused by a construction with additional wiring, may be reduced. Also, an expansion that can install an additional device to a network with only a plug-in, even after constructing the network, is guaranteed. Thus, the PLC technology is widely utilized for any type of wired/wireless network solutions.
FIG. 1 is a block diagram illustrating a configuration of a network including a subscriber network using a telephone network and a home PLC system according to a conventional art.- Referring to
FIG. 1 , atelephone office 110 includes a Digital Subscriber Line Access Multiplexer (DSLAM)111 and a private branch exchange (PBX)112. The DSLAM111 corresponds to a multiplexing device which can collect data, transmitted/received by any type of Digital Subscriber Line (xDSL), and transmit the collected data to an Internet Protocol (IP) network. Specifically, the DSLAM111 functions as an interface between an xDSL subscriber and a service provider and thus may provide the xDSL subscriber with various types of network functions. - In
FIG. 1 , the DSLAM111 receives a data signal from a video on demand (VOD) system, a Voice over Internet Protocol (VOIP) system, or an Internet network, multiplexes the data signal, and transmits the multiplexed data signal to anxDSL modem 123 of a subscriber location via atelephone line 114. In this instance, thetelephone line 114 may be coupled with another telephone line, connecting with the PBX112, by acoupler 113. Specifically, the data signal transmitted from the DSLAM111 and a voice signal transmitted from thePBX 112 are coupled with each other by thecoupler 113, and transmitted to anothercoupler 121 installed in thesubscriber location 120. - The
other coupler 121 installed in thesubscriber location 120 receives the coupled data signal and voice signal via thetelephone line 114. Also, thecoupler 121 splits the voice signal and the data signal respectively, and then transmits the voice signal to atelephone 122 and transmits the data signal to thexDSL modem 123. - The
xDSL modem 123 transmits the data signal to aPLC modem 124. ThePLC modem 124 converts the data signal into a signal corresponding to a predetermined PLC protocol, couples the converted signal with apower line 126, and transmits the coupled signal to at least one communication terminal. - In this instance, each of the at least one communication terminal includes another
PLC modem 125. Theother PLC modem 125 extracts a data signal from a PLC signal transmitted via thepower line 126, and transmits the extracted data signal to each of the at least one communication terminal. In this instance, the communication30 terminal may include a home automation device, a personal computer (PC), a television (TV), a security system, and the like. - In a PLC system according to the conventional art, a home network and various types of communication services may only be provided by utilizing a previously installed power line, without installing an additional wiring to a subscriber location. However, as described with
FIG. 1 , only when an xDSL modem and a PLC modem are separately installed in the subscriber location, a subscriber of a PLC service may utilize the PLC service. Also, only when the xDSL modem and the PLC modem perform protocol conversion according to a communication protocol between the xDSL modem and the PLC modem in the subscriber location, the xDSL modem and the PLC modem may transmit/receive a signal with an external location. - Also, in the case of an xDSL communication, a frequency band between an uplink and a downlink is different. Therefore, the at least one communication terminal, which is installed in the subscriber location, may not communicate with each other. So that a communication terminal installed in a first subscriber location may communicate with another communication terminal installed in a second subscriber location, a protocol conversion has to be performed via a PLC modem installed in each subscriber location. Also, the communication terminal of the first subscriber location may communicate with the other communication terminal of the second subscriber location only via a DSLAM.
- As an example, in the conventional art, when an xDSL modem is installed in a subscriber location, although a communication between subscribers is performed in the same apartment area, a data signal has to pass through a DSLAM of a telephone office to perform the communication. Also, in a line configuration according to the convention art, a plurality of subscriber locations may not perform a one-to-N communication and may perform only a one-to-one communication.
- Accordingly, a development of a PLC system which can outperform the conventional art, utilize an existing telephone line and a power line as is, and can apply a PLC frame in each subscriber location without performing a PLC protocol conversion, and enables a one-to-N communication between a plurality of subscriber locations when communication terminals of subscriber locations are connected to each other, is required.
- The present invention provides a power line communication (PLC) Digital Subscriber Line Access Multiplexer (DSLAM) which enables a PLC frame signal to be utilized as is in each subscriber location without performing a PLC protocol conversion with respect to a data signal in the each subscriber location via an xDSL modem and a PLC modem by receiving the data signal from a predetermined Internet Protocol (IP) network, converting the data signal into the PLC frame signal, and transmitting the converted PLC frame signal to at least one subscriber location via a telephone line.
- The present invention also provides a PLC coupling device which can embody a PLC using an existing telephone line and a power line without a protocol conversion of a data signal and additional power supply, by coupling a PLC frame signal, which is transmitted via a telephone line of a subscriber location, with the power line, and then transmitting the PLC frame signal to at least one communication terminal installed in the subscriber location.
- The present invention also provides a PLC system where a PLC DSLAM, which is generally installed in a telephone office, converts a data signal into a PLC frame signal and transmits the converted PLC frame signal to each subscriber location, and thus, when performing a communication between a plurality of closely-located subscriber locations, such as subscribers in the same apartment area, and the like, a protocol conversion of a PLC frame signal via a PLC modem and a PLC DSLAM are not required, and the plurality of subscriber locations can directly transmit/receive the PLC frame signal.
- The present invention also provides a PLC system where telephone lines installed in a section between a PLC device and a PLC DSLAM with respect to a plurality of closely-located subscriber locations, such as subscribers in the same apartment area, and the like, are coupled to be parallel with each other and thus a one-to-N communication is enabled between closely-located subscribers without a PLC protocol conversion.
