摘　　要：实现了国内首例全面实现 2 .5GATM/POS、GE、FE的宽带网络测试接口的研制 .测试接口采用一种产生分析模块 ,支持多种接口模块 ,之间使用标准接口连接 ,主要发送和分析逻辑采用FPGA(FieldProgrammableGateArray)实现 ,对外通讯接口是以太网口 .采用实时操作系统 ,进行系统的初始化配置等以及与终端的通讯 .系统集成度高 ,控制灵活 。A 2.5Gbps ATM IP tester interface is introduced. It is the first one in China with 2.5G ATM/POS, GE and FE interfaces. It contains a GA (generating and analyzing) module and three interface modules. Standard interface protocol UtopiaIII/POSPHY3 is used to connect the GA module and the interface module. Most of the processing is implemented in FPGA (Field Programmable Gate Array). Communication with the terminal is performed through Ethernet port. RTOS (Real Time Operating System) is used to initialize the tester system and communicate with the terminal. The system is highly integrated, flexible, easy to control and easy for software and logic upgrading.
