摘要
通道化线卡是一类特殊的POS型线卡。研究OC48 POS线卡的设计与实现,给出线卡的整体设计方案。采用PM5360型链路层器件完成底层信号处理,而采用FPGA进行报文处理。重点讨论PM5360应用中的关键问题。通过设计灵活的芯片配置方案,该线卡可以适应OC48信号内低速率的OC3和OC12子层信号的灵活组合。
The channelized linecard is a special POS linecard.This paper researched the design and implementation of OC48 linecard,the whole design scheme was given.The design adopted the link layer chip PM5360 to process the low-level signals, and used FPGA to process messages.The key points in applying PM5360 is mainly discussed.By designing a flexible configuration trick for PM5360,the linecard can accommodate the low speed OC3 and OC12 signal's dynamic combination in the channelized OC48 signal.
