摘要
详细介绍并且分析了7号信令采集卡链路层设计的总体方案和工作原理,并对其接收和发送流程涉及到的重要环节进行了介绍。在已经成功研发的7号信令数据采集卡中,通过实际数据测试,已经成功地对7号信令的信号单元进行了正确的接收重组和组装发送,测试效果良好,符合测试要求。
This paper introduces and analyzes the total scheme and work principle of the No. 7 signaling system data acquisition card detailed, according to the whole key taches which concerned in that procedure in receiving and transmitting of L2, it gives all detailed introductions. Through the actual data testing, the data acquisition card can receive, reassemble and resend correctly the cell among No. 7 signaling system . Many times measurements of the No. 7 signaling system data acquisition card show that the design accords with the requirement of the testing, and has a good effect.
