摘要
采用Infineon的ATM与PDH系统芯片评估板,研究在ATM通过保留E1/T1设备的电路仿真服务(CES,circuitemulation service),实现PDH的E1/T1线路与ATM网络的互连。主要讨论了基于IDT77105的传输速率为25Mbps的ATM物理层硬件设计与软件实现,并在此基础上,完成了基于ATM的PDH数据传输实验过程。
With Infineon's ATM-PDH chipset evaluation board,this paper studies cover implement of interconnection between PDH El/T1 circuit and ATM by CES (circuit emulation service).This paper mainly discusses the hardware and software design of ATM PHY for this system on which PDH over ATM data transmission test is accomplished.
