| 摘 要： | 随着TD-SCDMA网络的建设,网络信令测试仪成为了TD产业链中的重要一环.目前TD网络的传输主要采用基于ATM的STM-1接口和基于IMA的E1_IMA接口.这几种接口信令数据的采集,最终都体现为对ATM信元的处理.本文介绍了TD-SCDMA网络信令测试仪中ATM数据采集卡的实现方案,主要分析了ATM数据采集卡嵌入式软件的各个模块,详细说明了数据采集卡的数据处理流程,以及驱动的设计.实际使用表明,本文提出的数据采集卡已经成功地对ATM不同适配层的信元进行了正确的接收重组和组装发送,具有很大的实用价值.

| Abstract: | With the developing of TD-SCDMA network, Network Analyzer has become more important in the TD industry chain. At present, the transport of TD-SCDMA mainly adopt the interface of STM-1 based on ATM and the interface of EI-IMA based on IMA. All the data acquisition is based on the process of ATM cell. This paper dedicates the implementation of ATM data acquisition card for TD-SCDMA network analyzer, analyses mainly the each module of embed software, illuminates detailed data processing flow and driving program. It had proved through practical appli cation that the data acquisition card can receive, reassemble and resend correctly the cell among ATM adapter layers. |
