ONU Timing Profiles for Optical Line Termination Interoperability

The patent applies preliminary action by pre-storing multiple timing parameter profiles in the ONU before deployment. Each profile corresponds to different OLT brands or models and contains pre-configured timing parameters. When an OLT is detected, the system automatically selects the appropriate pre-stored profile, eliminating the need for manual timing parameter adjustment and reducing operational complexity while maintaining connection reliability.

The patent implements self-service by enabling the ONU to automatically detect the OLT brand or model and autonomously select the corresponding timing parameter profile from its pre-stored database. The system performs self-configuration without requiring manual intervention, thereby eliminating time-consuming brand identification and timing adjustment processes while ensuring reliable connections through automated profile selection.

The patent applies universality by equipping the ONU with a multi-functional timing parameter selection capability. Instead of being hardwired for a single OLT brand, the ONU stores multiple timing profiles corresponding to different brands or models. The system can universally adapt to various OLT types by automatically selecting the appropriate profile, thereby maintaining ease of operation while significantly enhancing adaptability and compatibility across different equipment manufacturers.
