Abstract: Recovering a Remote PHY (R-PHY) device after a power interruption. A hardware component, upon detecting that input power to the R-PHY device will be imminently interrupted, provides an alarm signal to a central processing unit (CPU) in the R-PHY device. The CPU, in response to receiving the alarm, stores running parameter data for the R-PHY device in a non-volatile memory. The running parameter data is normally obtained through network communications during a boot operation of the R-PHY device. If certain conditions are satisfied, then the R-PHY device recovers from the interruption in input power using the stored running parameter data without obtaining the running parameter data through a normal boot operation, thus shortening the boot time.
