Prestige 650M-17 ADSL Modem
xii Preface
Preface
Congratulations on your purchase of the Prestige 650M-17 ADSL Internet Access modem.
The Prestige 650M-17 is an ADSL modem used for Internet/LAN access via an ISDN line. The Prestige
can run maximum upstream transmission rates of up to 832Kbps and maximum downstream transmission
rates of 8Mbps. The actual rate depends on the copper category of your ISDN wire, distance from the
central office and the type of ADSL service subscribed to. See the What is DSL section for more
background information on DSL and ADSL.
The Prestige’s 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
Your Prestige is easy to install and configure. All functions of the Prestige are software configurable via the
SMT (System Management Terminal) using Telnet. Advanced users may configure the Prestige using CLI
(Command Line Interface) commands.
Register your Prestige online at www.zyxel.com for free future product updates
and information.

xiv What is DSL?
What is DSL?
DSL (Digital Subscriber Line) enhances the data capacity of the existing twisted-pair wire that runs
between the local telephone company switching offices and most homes and offices. While the wire itself
can handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000
Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to
improve access to the Web - hence DSL technologies.
There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The
services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the
downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for
Internet users because more information is usually downloaded than uploaded. For example, a simple
button click in a web browser can start an extended download that includes graphics and text.
As data rates increase, the carrying distance decreases. That means that users who are beyond a certain
distance from the telephone company’s central office may not be able to obtain the higher speeds.
A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no
dialing required.
What is ADSL?
It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, this works well for a typical Internet session in which more information is
downloaded, for example, from Web servers, than is uploaded. ADSL operates in a frequency range that is
above the frequency range of voice services, so the two systems can operate over the same cable. What are
the advantages of ADSL from the point of view of the Network Service Provider (NSP) and the end user?

1.3 Applications for the Prestige
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your Prestige supports the TCP/IP protocol,
which the Internet uses exclusively. It is compatible with all major ADSL DSLAM (Digital Subscriber
Line Access Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a
backbone network interface/connection (for example, T1, OC3, DS3, ATM or Frame Relay). Think of it as
the equivalent of a modem rack for ADSL. A typical Internet Access application is shown below.
Figure 1-1 Internet Access Application
1.3.2 LAN to LAN Application
You can use the Prestige to connect two geographically dispersed networks over the ADSL line. A typical
LAN-to-LAN application for your Prestige is shown as follows.
