| 发明名称 | Communication device and power saving method thereof in data transmission system | ||
| 摘要 | A communication device and a power saving method in a data transmission system are provided that can achieve the prevention of element deterioration occurring when a check signal is transmitted during sleep, as well as reductions of transmission noise and power consumption. The communication device, which is connected to another communication device through transmission/reception links corresponding to multiple channels, respectively, includes communication sections corresponding to the multiple channels, respectively, and a control section that interrupts transmission outputs of the communication element when there is no data for transmission, and sequentially changes, among the multiple channels, a channel that transmits a check signal for checking a link state during a period in which the transmission outputs are kept interrupted. | ||

| 主权项 | 1. A communication device connected to another communication device through transmission/reception links corresponding to a plurality of channels, respectively, comprising: a plurality of communication units corresponding to the plurality of channels, respectively; and a control unit that is configured to interrupt transmission outputs of the communication units when there is no data for transmission, andsequentially change, among the plurality of channels, a channel that transmits a check signal for checking a link state during at least one period in which the transmission outputs are kept interrupted. | ||
