Zyxel 645 ADSL (Asymmetric Digital Subscriber Line) is the hottest technology for Broadband Internet Access as well as providing voice services simultaneously on the same copper line. ADSL line rate using DMT line coding supports up to 8M/1.5Mbps downstream which is more than 140 times faster than analog modem and 800K/512Kbups upstream for Full-Rate (T1.413 Issue2 and G.dmt) / G.lite standard. Such asymmetrical nature makes it ideal for the SOHO environment, where the downstream traffic is typically much higher than the upstream traffic.Users can now enjoy the multi-media and real time applications such as online gaming, video conferencing and other bandwidth-consuming services by subscribing to
