摘　　要：提出了一种用于SDH分析仪的开销捕获模块的设计方案,设计的开销捕获方式包括手动捕获模式、告警误码触发自动捕获模式和预设值触发自动捕获模式。在此基础上,创新性地提出智能分析映射与复用路径的开销捕获模式,不仅实现对RSOH、MSOH、HPOH、LPOH的相关开销内容进行捕获,而且还实现了对帧的复用及映射路径的智能分析功能。同时,采用具有FIFO结构的双端口RAM存储器,保证了捕获的数据存储的可靠性。A design scheme of overhead capture module for SDH analyzer is presented. It is designed with some mode of capture, it includes manual capture mode, automatically capture mode triggered by error or alarm, automatically capture mode triggered by the preset value; Based on the three modes, the innovative mode of intelligent capture and analysis path is designed. It not only capture the overhead of MSOH, RSOH, HPOH and LPOH but also can intelligently analyze the frame path of multiplexing and mapping. At the same time, the dual port RAM with FIFO structure is designed to ensure to storage the data of capture reliability.
