CATV equipment fast boot after power interruption

A method for recovering a remote node after a power interruption, comprising:

• upon detecting that input power to the remote node has been or will imminently be interrupted, providing an alarm signal to a central processing unit (CPU) in the remote node,
• wherein the remote node is a Remote MACPHY node (RMN) that comprises a Remote MACPHY device (RMD), a wireless base station, a CATV amplifier, a Wi-Fi hotspot, a microcell, or a passive optical network (PON) switch;
• the CPU storing running parameter data for said remote node in a non-volatile memory, wherein running parameter data is normally obtained during a boot operation on the remote node through network communications;
• and
• upon determining certain conditions are satisfied, recovering from the interruption in input power to said remote device using said stored running parameter data without obtaining said running parameter data through a normal boot operation of said remote node.

A Cable Television (CATV) equipment for recovering after a power interruption, comprising:

• one or more embedded central processing units (CPUs);
• a hardware component capable of providing an alarm signal to at least one of the one or more central processing units in CATV equipment upon detecting that input power to the CATV equipment has been or will imminently be interrupted,
• wherein the hardware component is a Remote MACPHY node (RMN) that comprises a Remote MACPHY device (RMD), a wireless base station, a CATV amplifier, a Wi-Fi hotspot, a microcell, or a passive optical network (PON) switch;
• the at least one CPUs capable of storing running parameter data for said CATV equipment in a non-volatile memory, wherein running parameter data is normally obtained during a boot operation on the CATV equipment through network communications;
• and
• the CATV equipment configured to, under certain conditions being satisfied, recover from the interruption in input power using said stored running parameter data without obtaining said running parameter data through a normal boot operation.
