Abstract: A method for registering customer premises equipment to provide an Internet service to the customer premises equipment by a network management apparatus of an access network structure, wherein the network management apparatus and the customer premises equipment are connected through a bundle cable including a plurality of lines in the access network structure, the method includes: transmitting a registration signal toward a customer premises equipment; receiving registration response signals transmitted from the customer premises equipment through the plurality of lines; analyzing the registration response signals introduced from the plurality of lines and distinguishing a direct signal transmitted through a properly connected line and interference signal from the registration response signals; and establishing a link with the customer premises equipment connected to the properly connected line.

Abstract: A method for configurating a transmission mode to provide an Internet service to a customer-premises equipment by an transmission mode configurating apparatus in an access network structure is provided. At least one network management equipment and at least one customer-premises equipment are connected through a bundle of cables including a plurality of transmission lines. The method includes determining the number of transmission lines connected to the customer-premises equipment; determining at least one of available transmission mode to provide depending on the number of transmission lines; if a plurality of available transmission modes are determined, calculating a transmission performance in each of the available transmission modes; and selecting the transmission mode with the highest performance among the plurality of the available transmission modes.

Abstract: Disclosed is a method for performing transmission frequency control for a subscriber line of a customer premise device by a transmission control apparatus in an access network structure in which at least one network management device and a plurality of customer premise devices are connected through a bundle cable including a plurality of subscriber lines. The transmission control method includes: setting a partial frequency band in an entire service frequency band provided by the subscriber line as a transmission frequency band of the customer premise device; and varying the transmission frequency band in the entire service frequency band when a triggering event occurs, in which traffic of the customer premise device is transmitted and received in the transmission frequency band.

Abstract: Disclosed is a device and method for decreasing interference in a cable bundle. The device includes a plurality of concentration devices, an interference measurer, and a concentration device. Each concentration device accesses an uplink and provides a network service to a terminal through a cable bundle in an access section. An interference measurer is connected between the cable bundle and the terminal. The interference measure is configured to measure an interference signal by measuring a signal transmitted to the terminal through the cable bundle, calculate an interference coefficient for generating a quasi-interference signal, and transmit the same to the concentration devices. The concentration devices is configured to calculate an additional signal for offsetting an interference signal by using the interference coefficient, add the additional signal to the original signal, and transmit the additional signal to the cable bundle.
