ADSL (Asymmetric Digital Subscriber Line) is the

hottest technology for Broadband Internet Access

as well as for providing voice services

simultaneously on the same copper line. ADSL

line rate using DMT line coding supports up to

8M/1.5M bps downstream, which is more than

140 times faster than analog modems, and 800k/

512k bps upstream for Full-Rate (T1.413 Issue2

and G.dmt) / G.Lite standard. This asymmetric

nature makes it ideal for the SOHO environment,

where the downstream traffic is typically much

higher than the upstream traffic. Users can now

enjoy multi-media and real time applications

such as online gaming, video conferencing and

other bandwidth-consuming services by

subscribing to ADSL.

Multiple-ﬂavor ADSL Standard

The Prestige 645 series offers auto-sensing between Full-Rate and

G.Lite standards according to Central Ofﬁce switch or DSLAM

(Digital Subscriber Line Access Multiplier) so a user can easily be

upgraded from a G.Lite service to a Full-Rate service or vice versa

without the cost of a new ADSL modem or router.

Plug-and-Play Connectivity

Pre-conﬁgured with service provider’s settings, the Prestige 645 series

can be automatically installed and work with your ADSL connection

without any manual conﬁguration.

First PPPoE Implementation in the World for Virtual Dial Up

Incorporating ZyXEL’s first-in-the-world PPPoE implementation, the

Prestige 645 series enables users as well as service providers to make

use of the existing PPP/PAP/CHAP based authentication and

accounting infrastructure. Users don’t need to pay extra for PPPoE

software while still enjoying the benefit of PPPoE.

Ease of Use and Management

The Prestige 645’s SMT(System Managment Terminal) and the

optional Web-based configurator makes the configuration easier for

the users while saving time and support effort for service providers.
