本文介绍了7 号信令采集终端的设计方法,该设计方法经过了国家十五重大专项“7 号信令网管理系统”项目测试能够正常运转,为下一步进行soc 设计做好了充分准备。该终端通过与传输网的连接向七号信令网管理系统提供可靠的信令数据来源。这个系统的硬件平台是基于xilinx 公司的大容量FPGA 的。与以往同类产品不同的是这个系统的软硬件部分集中在一块fpga 中,并且有很强的处理数据的能力。经过测试,该设计方案的性能优于现有同类型的7 号信令采集产品。 关键词:NO.7 信令,采集终端,片上系统 Abstract –This paper introduces the design method of signaling No. 7 collection terminal. The methed passes through the country’s tenth five-year-plan project testing on " signaling No. 7 managing system of network ",and can run well, making adequate preparation for carrying on SOC design in the following stage. This design method offer reliable signals to signaling No. 7 managing system through the link to transmission networks . Our Hardware plat is based on FPGA.of Xilinx Co.Different from anciently products,this system is in a fpga chip.And has powerful processing ability. After testing,the performance of the system is superior to the existing similar signaling No.7 collection products. Keywords: signalingNo.7, collection terminal, SoC
