What Is ADSL? xv
What Is DSL?
DSL (Digital Subscriber Line) technology 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.

Access.

Getting to Know Your Prestige 1-1
Chapter 1
Getting to Know Your Prestige
This chapter describes the key features and applications of your ADSL Internet Access Bridge .
1.1 Prestige 645M ADSL Internet Access Bridge Overview
Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN interface and a high-speed ADSL
port into a single package. The Prestige is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks.
1.2 Features of the Prestige 645M
Your Prestige is packed with a number of features that give it the flexibility to provide a complete Internet
access solution for almost any user.
Ease of Installation
Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size and lightness
make it easy to position anywhere in your busy office.
High Speed Internet Access
The P645M ADSL bridge can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 800 Kbps.
10/100Mbps Fast Ethernet LAN Interface
The P645M's 10/100M LAN interface enables fast data transfers of 10Mbps or 100Mbps in either half-duplex
or full-duplex mode depending on your Ethernet network.
Protocols Supported
♦ TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.

Prestige 645M-A1 ADSL Bridge
1-2 Getting to Know Your Prestige
♦ PPP (Point-to-Point Protocol) link layer protocol.
Networking Compatibility
Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers, making configuration as simple as possible for you.
Multiplexing
The P645M supports VC-based and LLC-based multiplexing.
Encapsulation
The Prestige 645M supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5) and RFC 1483
encapsulation over ATM.
Full Network Management
♦ SMT (System Management Terminal) through a telnet connection.
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure since the password is scrambled prior to transmission.
However, PAP is readily available on more platforms.
Filters
The Prestige's packet filtering functions allow added network security and management.
Reset Button
The Prestige comes with a reset button built into the rear panel. Use this button to restore the factory default
password to 1234, IP address to 192.168.1.1 and the subnet mask to 255.255.255.0.
1.3 Applications for the Prestige 645M
1.3.1 Internet Access
