A cable network system using a channel bonding, a channel testing method and a channel moving method are provided to automatically switch to other channel in case that a bad conditioned channel is found under environment where plural channels are bonded and used, and to reduce a network management cost. A cable network system includes a concentrating equipment(110) and a premises equipment(120). The concentrating equipment distributes downlink data to downlink channels in correspondence with capacity of a coaxial cable, transmits the downlink data via the downlink channels, reassembles uplink data distributed to and transmitted via plural uplink channels in correspondence with capacity of the coaxial cable, identifies a bad conditioned channel among the uplink channel, and moves to other channel. The premises equipment reassembles downlink data distributed to and transmitted via plural downlink channels in correspondence with capacity of the coaxial cable, distributes uplink data to plural uplink channels and transmits the uplink data via the uplink channels in correspondence with capacity of the coaxial cable.
