PS:Zyxel 網站的 642R 說明資料

Incorporating ZyXEL' s first-in-the-world PPPoE implementation, Prestige 642 series enables the users as well as the service providers to make use of the existing dial-up Internet infrastructure. It makes the Internet services charged by usage time that is similar to the dialup scenario. Users don't need to pay extra for PPPoE software while still enjoying the benefit of PPPoE.
