AI Technical Summary

Technical Problem

In the existing network management system, the ONU only supports single protocol communication between the master device, which cannot meet the efficient needs of bidirectional information interaction, and does not support complex configuration operations such as WAN and LAN IP, which is inconvenient to manage.

Method used

Dual protocol communication (RS485 and TTL) technology is adopted to dynamically allocate addresses to multiple ONUs through the address allocation module, and to realize complex configuration and management operations such as WAN and LAN IP through the management module.

Benefits of technology

It enhances the flexibility of data transmission between the master control device and multiple ONUs, avoids address conflicts, supports the access and management of multiple ONUs, and has comprehensive monitoring and control functions to meet the usage needs of large-scale and multi-device scenarios.

Abstract

The invention discloses a multi-ONU (optical network unit) centralized management system for dual-protocol communication. The multi-ONU centralized management system comprises main control equipment and at least one optical network unit, each optical network unit is provided with two groups of 10PIN pin headers, and the plurality of optical network units are connected in series through the 10PIN pin headers; the main control equipment is connected with an idle 10PIN pin header of one optical network unit; the main control equipment comprises an address distribution module and a management module; the address allocation module is used for performing address allocation on the optical network unit through an RS485 protocol and a TTL protocol; the management module comprises a WAN configuration unit, an LAN side IP setting unit, a PON mode configuration unit, an LAN port configuration unit and a restart recovery unit. According to the invention, the flexibility of data transmission between the main control equipment and the plurality of ONUs is enhanced.
