摘要
宽带无源光网络(BPON)系统是一种优良的高速、宽带接入解决方案,是实现光纤到户(FTTP)的重要解决方案之一.在介绍BPON系统的网络分层结构基础上,分析了光网络终端(ONT)设备实现的主要功能,讨论了实现方案.利用嵌入式思想开发ONT系统,并研究了软件设计的主要方法.将软件划分为5个模块,设计出每一模块的流程,并讨论了其中的消息处理核心功能的实现过程.
BPON（Broadband Passive Optical Network based on ATM） is a kind of excellent broadband access platform with high speed and is one of the most important solution to realize fiber to the premise. After introducing the layered structure, principle of BPON, analyzing the main function of ONT,the hard ware designing process is discussed. The ideas of embedded designing ONT is given in this paper, and the key techniques of TC layer are researched. The software designing methods are also issued. There are five models in software low level desiging. The flowchart of each is given, and the key method of messege handling is researched.
