Problems solved by technology

[0004] In the GPON (Gigabit Passive Optical Network) system, according to the ITU-T G.984 standard, the OLT uses the OMCI (Optical Network Equipment Management and Control Interface) method to manage the ONU, and defines the manageable parameters, but the management of some personalized ONU-specific modules in other industries such as electric power and radio and television also has the problem that the standard is not defined or the existing chips cannot be realized.

Embodiment Construction

[0049] The invention solves the management problem of the ONU expansion module that does not define management parameters in the PON standard protocol, or cannot be realized by existing chips, but needs remote management. The present invention utilizes the two-layer (that is, the data link layer of the second layer of the OSI network protocol seven-layer model) message to obtain and distribute the IP address for mutual communication, and uses the UDP message to communicate between the OLT and the ONU, and remotely manages the ONU extension The module uses a variety of judgment conditions to ensure communication connection and configuration delivery.

[0050]1. The implementation content on the ONU side is as follows:

[0051] (1) When the ONU is powered on, it sends a defined Layer 2 broadcast packet to the OLT, carrying the ONU PON MAC and CPU MAC, to obtain the IP address for extended communication.

[0052] (2) After the ONU receives the Layer 2 message (carrying the IP ad...

Abstract

The invention provides a method for realizing extension communication between an OLT (Optical Line Terminal) and an ONU (Optical Network Unit). The method comprises the steps of obtaining and distributing IP (Internet Protocol) addresses in mutual communication by utilizing two layers of messages, carrying out the communication between the OLT and the ONU by utilizing a UDP (User Datagram Protocol) message, remotely managing an ONU extension module, and ensuring communication connection and configuration issuing by utilizing multiple judging conditions. According to the method provided by the invention, the problems that management parameters are not defined in a PON (Passive Optical Network) standard protocol, or the management of the ONU extension module is not realized by an existing chip but needs to be subjected to remote management can be solved.

Description

technical field [0001] The invention relates to a method for implementing extended communication between an OLT (Optical Line Terminal) and an ONU (Optical Network Unit) in a PON (Passive Optical Network) network. Background technique [0002] With the development of PON technology, its application scope has expanded from traditional telecom operators to industries such as electric power and radio and television. According to their own business characteristics, these emerging application industries have put forward many personalized application requirements for the PON system, and corresponding ONUs have also been produced accordingly. For example, the ONU that supports the extended serial port function is used to connect the meter reading system in the power industry to realize remote meter reading. Another example is the ONU that supports the CATV (cable TV) function, which is used to transmit CATV signals to the home and realize the triple play of fiber-to-the-home. But...
