Abstract
Devices, systems and methods for performing maintenance in Data over Cable Service Interface Specification (DOCSIS) network CPE devices and for improving recovery to a normal operating state from maintenance are provided. The devices, systems and methods provide for entering a standby mode for an electronic device for a duration of a maintenance period. A currently-used RF communication channel frequency of the electronic device is stored as a last known channel frequency into a memory. RF communication channel operation between the electronic device and an upstream content distribution device is suspended for the duration of the maintenance period. After the maintenance period, the last known channel frequency is used to reestablish a communication connection between the electronic device and the upstream content distribution device.
