Embodiment Construction

[0018] Referring now to the accompanying drawings, figure 1 It is the format diagram of the communication line from the ordinary telephone office to the CPE.

[0019] refer to figure 1 , as for a communication method like xDSL, xDSL is transmitted from the telephone office to the adjacent home DSLAM 20 through an optical cable, and is connected from the DSLAM 20 to the CPE 30 using a telephone line (twisted pair).

[0020] At this time, most of the telephone wires are bundled into a bundle, and the bundle is bundled by multiple telephone wires, and is divided into the entrance of each family through a distributor or junction box (TAB) to connect with the family.

[0021] Typically, the telephone lines assigned to each household in a bundle are provided by about 4 to 5 spare telephone lines 2 . Of these telephone lines, however, only one with the best performance is used 1 . That is to say, 3 to 4 telephone lines 2 are provided to each household as spare lines even if they a...

Abstract

A system for extending an x Digital Subscriber Line (xDSL) distance using a reserved telephone line in accordance with the present invention, includes: a Customer-Provided Equipment (CPE) for supplying an x Digital Subscriber Line (xDSL) transmission service to a subscriber terminal; a Digital Subscriber Line Access Multiplexer (DSLAM) setting an initial link with the Customer-Provided Equipment (CPE) for the x Digital Subscriber Line (xDSL) transmission service, and transceiving data with the Customer-Provided Equipment (CPE) through the set link; and a distance extension module being installed with at least more than one module between the Digital Subscriber Line Access Multiplexer (DSLAM) and the Customer-Provided Equipment (CPE), in order to receive x Digital Subscriber Line (xDSL) transmission data from the Digital Subscriber Line Access Multiplexer (DSLAM) in connection with an optional reserved telephone line selected from telephone line bundles incoming from the Digital Subscriber Line Access Multiplexer (DSLAM), and after separating the received transmission data, to transmit the separated transmission data to a module of a back end or the Customer-Provided Equipment (CPE) or to transmit transmission data received from the module of the back end or the Customer-Provided Equipment (CPE).

Description

[0001] This application claims the benefit of Korean Patent Application No. 2003-111479 filed on February 24, 2003, the disclosure of which is hereby incorporated by reference. technical field [0002] In general, the present invention relates to a system for extending x DSL (xDSL) distance using spare telephone lines, and more particularly, to a system for extending xDSL distance using spare telephone lines, which overcomes the problem of extending xDSL distances by using bundled The access multiplexer (DSLAM) is connected to the telephone line in the home, as the backup line provided by the xDSL distance limit exists for the backup phone line. Background technique [0003] In terms of the communication line form from the ordinary telephone office to the customer-provided equipment (CPE), as for the communication method similar to xDSL, the xDSL is transmitted from the telephone office to the DSLAM of the adjacent home through an optical cable, and the telephone line (twiste...
