Techniques involving the transfer of signals across interconnection media are disclosed. For instance, an apparatus may include an apparatus having an interconnection medium, a first device that may drive the interconnection medium, and a second device. The second device may include a pull-up resistor that is selectively coupled between the interconnection medium and a power source. For instance, the second device may disconnect a power source from the interconnection medium when the first device is in a power saving operational state. Otherwise, the pull-up resistance is coupled between the power source and the interconnection medium.
