Abstract
Power saving in computing devices is provided. A first computing device communicates with a second computing device using a first set of tones. A low power event is detected by the first computing device. In response to the detected low power event, a request to communicate using a second set of tones is sent to the second computing device by the first computing device. The second set of tones has fewer tones than the first set of tones, and may be a subset of the first set of tones.
Claims20
A method comprising:
- communicating by a first computing device using a first set of tones with a second computing device;
- detecting a low power event by the first computing device;
- and
- in response to the detected low power event, sending a request to communicate using a second set of tones to the second computing device by the first computing device, wherein the second set of tones has fewer tones than the first set of tones.
1 more element
A method comprising:
- communicating with a first computing device using a first set of tones by a second computing device;
- receiving, at the second computing device from the first computing device, an indication of a low power event;
- in response to the indication of a low power event, sending an instruction to the first computing device to communicate using a second set of tones by the second computing device;
- and
- communicating with the first computing device using the second set of tones by the second computing device.
2 more elements
A system comprising:
- a digital subscriber line (DSL) modem that communicates using a first set of tones with a digital subscriber line access multiplexer (DSLAM);
- a power manager that detects a low power event;
- and
- a save-our-showtime (SOS) engine that, in response to the detected low power event, sends a request to communicate using a second set of tones to the DSLAM, wherein communicating using the second set of tones uses less power than communicating using the first set of tones.
