VDSL及以太网宽带接入

VDSL and Ethernet Broadband Access

首先回顾了宽带接入技术的发展,然后介绍了VDSL和以太网交换这两种技术的现状,着重分析了它们的基本工作原理和设计思想。最后以亿恒公司的芯片解决方案为例,为采用VDSL和以太网交换的宽带接入系统给出了一种功能完整的实现方法。

After reviewing the develop-ment background of broadband access technologies,the basic principle and de-sign conception of VDSL and Ethernet switch are presented.Then a broadband access solution with complete functions based on chipset(10BaseS,AR2224)from Infineon Technology is given as an application example.
