Abstract
Systems and methods can provide for power saving in broadband communications devices. In some implementations, such systems and methods can generate and/or receive interrupts to ascertain external power unavailability, operate on battery power, instruct functional modules to enter power saving mode, await restoration of external power, and instruct modules to resume normal operations. In other implementations, such systems and methods can detect external power unavailability via polling, operate on battery power, instruct any or all of primary and auxiliary processor(s) to enter power saving mode, monitor when external power has been restored, and instruct functional modules to resume normal operation. Power saving mode can reduce the rate of modem battery drain and thus reduce the likelihood of a service outage and extend service duration.
