| 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 (13-1 to 13-N, 141 to 14-N) corresponding to the multiple channels, respectively, and a control section (10) 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. |

1. A communication device connected to another communication device through transmission/reception links corresponding to multiple channels, respectively, comprising:
communication sections corresponding to the multiple channels, respectively; and a control section that interrupts transmission outputs of the communication sections 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. |
