PoE Powered Device Dynamic Power Reclassification

The patent combines the power delivery functions by allowing the IP telephone to act as an intermediate power source for the plug-in module. The telephone receives power from the PoE device and redistributes it to the module, eliminating the need for separate power cubes and external power supplies. This merging of power delivery paths reduces device complexity and removes location constraints.

The IP telephone serves as an intermediary device between the PoE power source and the plug-in module. It detects the module's power requirements through classification signals and dynamically adjusts its power consumption profile to request sufficient power from the PoE device, then provides the appropriate power level to the module through the data connection.

The system implements dynamic power adjustment by allowing the IP telephone to change its power classification in real-time. When a module is detected, the telephone transitions from its original power class to a higher power class that accommodates the combined power requirements of the telephone and module, ensuring continuous operation without power deficits.

The power management system uses feedback from module detection and classification signal exchange to dynamically adjust power allocation. The telephone monitors the module's presence and power needs, then communicates updated power requirements to the PoE device through reclassification, creating a closed-loop power management system that adapts to changing conditions.
