【Abstract】 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.更多还原
