System for extending distance of x Digital Subscriber Line using reserved telephone line

A method for extending a distance of x Digital Subscriber Line using a reserved telephone line, comprising:

• supplying an x Digital Subscriber Line transmission service to a subscriber terminal by a Customer-Provided Equipment;
• setting an initial link with the Customer-Provided Equipment for an x Digital Subscriber Line transmission service, and transceiving data with the Customer-Provided Equipment through the set link by a Digital Subscriber Line Access Multiplexer;
• and
• installing a distance extension module with at least more than one module between the Digital Subscriber Line Access Multiplexer and the Customer-Provided Equipment, in order to receive x Digital Subscriber Line transmission data from the Digital Subscriber Line Access Multiplexer in connection with an optional reserved telephone line selected from telephone line bundles incoming from the Digital Subscriber Line Access Multiplexer, 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, or to transmit transmission data received from the module of the back end or the Customer-Provided Equipment.

A system for extending a distance of x Digital Subscriber Line using a reserved telephone line, comprising:

• a first unit supplying an x Digital Subscriber Line transmission service to a subscriber terminal;
• a second unit setting an initial link with the first unit for an x Digital Subscriber Line transmission service, and transceiving data with the first unit through the set link;
• and
• a third unit being installed with at least more than one module between the Digital Subscriber Line Access Multiplexer and the first unit, in order to receive x Digital Subscriber Line transmission data from the second unit in connection with an optional reserved telephone line selected from telephone line bundles incoming from the second unit, and after separating the received transmission data, to transmit the separated transmission data to a module of a back end or the first unit, or to transmit transmission data received from the module of the back end or the first unit.
