xxii Preface

Prestige 642R Series ADSL Router

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, e.g., 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?

Advantages to the Network Service Provider (NSP)

1. ADSL enables telephone companies (telcos) to use the world's nearly 750 million existing copper wires

to deliver affordable high-speed remote access to the Internet, corporate networks and on-line services
over ordinary phone lines.

2. ADSL enables new applications that require real-time, interactive multimedia and broadcast-quality

video. Such applications include collaborative computing, video conferencing, distance learning and
video-on-demand.

3. The industry is rapidly converging on standards that will enable interoperability and ultimately make a

mass market possible.

4. ADSL empowers service providers to provide either a guaranteed sustained or adaptive rate, or best

effort service similar to analog modems.

¾ Nearly 300 times faster than 24.4 Kbps modems
¾ Over 100 times faster than 56 Kbps modems
¾ 70 times faster than 128 Kbps ISDN

5. Both residential and business properties around the world are already running out of spare lines on

existing installed telephone cables. ADSL provides service providers with the capability to use one line
to provide new data services while maintaining the telephone service on the same line, thus leveraging
the existing infrastructure.

What is DSL? xxiii

Prestige 642R Series ADSL Router

6. ADSL provides telcos with the ability to offer a private, secure channel of communications between
the consumer and the service provider.

7. Data travels along the customers own line, unlike cable telephone and modem services where the line is
shared with others

8. Because it is one customer's dedicated line, transmission speeds are not affected by other users going
on-line. With cable modems, transmission speeds drop significantly as more users go on-line

9. ADSL is "always on" and connected, just like a standard telephone. There is no time wasted dialing up
the service several times a day and waiting to be connected; ADSL is on standby, waiting ready for use
whenever your customer is ready.

10. Every major service provider has conducted trials and proven that the technology works. Today,
service providers are rolling out ADSL services worldwide, with widespread deployment expected. In
support of this market, a large number of major equipment vendors are shipping second and third­generation products offering higher performance and lower costs.

11. ADSL-based networks are well suited for carrying ATM traffic, thus guaranteeing ADSL technology
for decades to come.

12. ADSL provides the communication bridge into the next century without adding new infrastructure,
costly outside plant additions and reinvestment.

Advantages to the End User

1. ADSL transforms plain old telephone lines into a high speed conduit for data, information,

entertainment and more. And while it is doing that, you can use your telephone for normal
conversations at the same time. This provides enormous advantages whether at home or at work.

2. ADSL provides affordable high-speed remote access to the Internet, corporate networks and on-line
services over ordinary phone lines.

¾ Nearly 300 times faster than 24.4 Kbps modems
¾ Over 100 times faster than 56 Kbps modems
¾ 70 times faster than 128 Kbps ISDN

For example, if there were no constraints of the Internet backbone or if fast servers were located in every
telephone central office, an ADSL modem could download the entire Encyclopedia Britannica to a user's
laptop in 16.6 minutes, compared to 6.4 days using a typical modem speed of 14,400 bps.

3. ADSL enables the use of real-time, interactive multimedia and broadcast-quality video for such new
services as collaborative computing, video conferencing, distance learning and video-on-demand.

4. ADSL gives you the ability to have both voice and data services in use simultaneously and all over one
phone line. Both residential and business properties around the world are already running out of spare
lines on existing installed telephone cables so effectively doubling your capacity in this way is a real
benefit.

5. ADSL provides a private, secure channel of communications between you and the service provider.

6. Your data travels along you own line, unlike cable telephone and modem services where the line is

shared with others.

7. Because it is your own dedicated line, transmission speeds are not affected by other users going on­line. With cable modems, transmission speeds drop significantly as more users go on-line.

use whenever you are.

Prestige 642R Series ADSL Router

Chapter 1

Getting to Know Your ADSL Internet Access

Router

This chapter describes the key features and applications of the Prestige 642

1.1 Prestige 642R Series ADSL Internet Access Router

Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN interface and one high-speed
ADSL port into a single package. The Prestige is ideal for high-speed Internet browsing and making LAN­to-LAN connections to remote networks.

1.2 Features of the Prestige 642R

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.

z High Speed Internet Access

The P642 ADSL router can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 640Kbps. The P642 also supports rate management; rate management allows ADSL
subscribers to select an Internet access speed that best suits their needs and budgets.

z PPPoE Support (RFC2516)

PPPoE (Point-to-Point Protocol over Ethernet) emulates a Dial-Up connection. It allows your ISP to use
their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver
on the Prestige is transparent to the PCs on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual PCs.

z Transmission Rate Standards

1

♦ Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2))
♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt(G.992.1)) with line rate support of up to 8Mbps

downstream and 1024kbps upstream.

♦ G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream.

z IP Alias

IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface.
The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the
Prestige itself as the gateway for each LAN network.

Prestige 642R Series ADSL Router

z IP Multicast

Traditionally, IP packets are transmitted in two ways: unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to
support multicast groups. The latest version is version 2 (see RFC2236). Both versions 1 and 2 are
supported by the Prestige

z IP Policy Routing (IPPR)

Traditionally, routing is based on the destination address only and the router takes the shortest path to
forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior
and alter the packet forwarding based on the policy defined by the network administrator.

z 10/100M Fast Ethernet LAN Interface

The P642'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.

z Protocols Supported

TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.



PPP (Point-to-Point Protocol) link layer protocol.



SUA™ (Single User Account) and NAT (Network Address Translation).



z Multiple Protocol Support

♦ Novel IPX (Internetwork Packet eXchange) network layer protocol.
♦ Transparently bridging for unsupported network layer protocols.

z DHCP Support

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has the built-in DHCP
Server enabled by default. DHCP Relay allows the Prestige to act as a surrogate DHCP server where it
relays IP address assignment from the actual DHCP server to its clients.

z Multiple PVC (Permanent Virtual Circuits) Support

Your Prestige supports up to 8 PVC’s.

z 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.

z Multiplexing

The Prestige 642R Series supports VC-based and LLC-based multiplexing.

z Encapsulation

The Prestige 642R Series supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM, MAC encapsulated routing as well as PPP over Ethernet (RFC 2516).

1-2 Getting to know your Prestige

Prestige 642R Series ADSL Router

z NAT/SUA for Single-IP-address Internet Access

The Prestige's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a
single IP account. SUA supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealAudio, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.

z Full Network Management

♦ SNMP (Simple Network Management Protocol) support.
♦ Accessing SMT (System Management Terminal) through a Telnet connection
♦ Windows-based PNC (Prestige Network Commander)

z 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.

z Filters

The Prestige's packet filtering functions allows added network security and management.

z Ease of Installation

Your Prestige is designed for quick, intuitive and easy installation.

z Housing

Your Prestige's all new compact, ventilated housing minimizes space requirements making it easy to
position anywhere in your busy office.

1.3 Applications for the Prestige 642R

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 (e.g., 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.
