The host computer can set the modem into USB sleep (L1) state (to save battery power)
whenever the link is idle. To return from sleep state the host computer performs
L1Resume. This can also be triggered by the modem using L1-Remote- Wake-up. The
sleep (L1) state is introduced by “USB 2.0 Link Power Management Addendum” and
allows fast state transitions between active and sleep states.

The PC can set the modem into USB suspend state (to save battery power) when no
communication takes place or when the PC is switched into standby mode. The suspend state
also can be triggered by X-GOLD™ Baseband device through a proprietary device initiated
selective suspend mechanism. The wake up is performed by Host Resume. The modem can
wake up the host computer from standby state using Remote Wake-up
