RPR综合业务接入平台的POS接口单元设计

Design of POS interface unit for integrated service access platform of RPR

针对RPR综合业务接入平台,提出并实现了一种基于FPGA的POS接口单元设计方案,主要完成了平台中IXP1200网络处理器IX接口的转换,对外提供两路POS-PHYLevel2接口。仿真和综合结果表明,该设计灵活有效,占用资源面积小,支持的工作频率高,良好地满足了高速接入的要求。

In this paper, we propose a design scheme of POS interface for integrated service access platform of RPR. In this scheme, we mainly realized the conversion between IX bus of network processor IXP1200 in the platform and two POS-PHY Level 2 ports for external devices. Moreover, the interface design was implemented on FPGA, simulation and synthesis results show that the interface supports high data rate at reasonable complexity.
