本文介紹了7 號信令采集終端的設計方法，該設計方法經過了國家十五重大專項“7 號信令網管理系統”項目測試能夠正常運轉，為下一步進行soc 設計做好了充分準備。該終端通過與傳輸網的連接向七號信令網管理系統提供可靠的信令數據來源。這個系統的硬件平臺是基于xilinx 公司的大容量FPGA 的。與以往同類產品不同的是這個系統的軟硬件部分集中在一塊fpga 中，并且有很強的處理數據的能力。經過測試，該設計方案的性能優于現有同類型的7 號信令采集產品。

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
