尽管ADSL的高速和畅通无阻的特性引起了用户的关注,但是,要想真正成为拨号调制解调器的替代产品,硬件成本必须降低。设计人员必须把研发重点放在调制解调器内的芯片组上,才能降低硬件成本,因为芯片组是决定产品特性和综合成本的关键元素。 Despite the high-speed and unobstructed nature of ADSL that draws the attention of users, hardware costs must be reduced in order to truly become an alternative to dial-up modems. Designers must focus their research and development on chipsets in their modems to reduce hardware costs as the chipset is a key element in determining product features and overall costs.
