Kai Shao · Electrical Measurement & Instrumentation · 2007
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 E1-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.
