AI Technical Summary

Technical Problem

Existing optical line termination devices require manual intervention for restoring configuration data due to potential damage or loss, which is inefficient and prone to errors.

Method used

An office-side optical line terminating device automatically generates backup data, divides it into fragments, and distributes these fragments to multiple subscriber-side devices for secure storage, enabling automatic recovery by collecting and combining the fragments when needed.

Benefits of technology

Enables secure and automatic recovery of configuration data without human intervention, ensuring data integrity and reducing the risk of data loss or corruption.
