摘　　要：本系统根据IEEE802.3ah OAM协议设计了一种基于ARM9和PAS5001NM3的新型EPON的OAM嵌入式系统。具体阐述了如何构建此系统的软硬件平台,在硬件设计上CPU与PAS5001采用16位总线通信的新设计方法,在软件设计上充分利用PAS-API函数,给出了事例说明。本系统成本低,效率高,具有广阔的的应用前景。A new dAM of EPON embedded system based on ARM9 and PAS5001NM3 according to IEEE802.3ah dAM protocol. Software and hardware of the system is described in detail. 16 bit bus communications between CPU and PAS5001 is adopted about hardware design, and PAS-API function is made best of about software design and example is listed. This system has low cost and better efficiency, and has wide application foreground.
