Prestige 623R-T ADSL Dual-link Router

Introduction to 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.

features and applications, accessing the web configurator and configuring the wizard screens for

initial setup.

Prestige 623R-T ADSL Dual-link Router

Chapter 1

Getting To Know Your Prestige

This chapter describes the key features and applications of your Prestige.

1.1 Introducing the Prestige 623R-T ADSL Dual-link Router

Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN interface and a high-speed DSL
port into a single package. The Prestige is ideal for high-speed Internet browsing and making LAN-to-LAN
connections to remote networks. Provided with both USB and Ethernet ports, computers can share local
resources (such as printers and files) and access to the Internet – simultaneously.

The web browser-based Graphical User Interface provides easy management.

1.2 Features of the Prestige

Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking 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.

USB Port

The USB port is useful if you have an USB-enabled computer that does not have a network interface card for
attaching to your Ethernet network. Refer to Quick Start Guide for USB driver installation procedure in
Windows 98 SE/Me/2000/XP.

High Speed Internet Access

The Prestige supports downstream transmission rates of up to 8Mbps and upstream transmission rates of 800
Kbps.

Getting To Know Your Prestige 1-1

Prestige 623R-T ADSL Dual-link Router

10/100Mbps Auto-negotiating Fast Ethernet LAN Interface

This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps 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.

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

• Transparent bridging for unsupported network layer protocols.

• DHCP Client, Server and Relay

• RIP I and RIP II

IP Policy Routing

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.

Call Scheduling

Configure call time periods to allow and restrict access to remote nodes.

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

Your Prestige supports VC-based and LLC-based multiplexing.

Encapsulation

The Prestige supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483 encapsulation
over ATM and MAC encapsulated routing (ENET ENCAP) as well as PPP over Ethernet (RFC 2516).

SNMP

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information
between network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP
agent functionality, which allows a manager station to manage and monitor the Prestige through the network.
The Prestige supports SNMP version one (SNMPv1) and version two (SNMPv2).

1-2 Getting To Know Your Prestige

Prestige 623R-T ADSL Dual-link Router

Network Address Translation (NAT)

Network Address Translation (NAT) allows the translation of an Internet protocol address used within one
network (for example a private IP address used in a local network) to a different IP address known
within another network (for example a public IP address used on the Internet).

Full Network Management

• SNMP (Simple Network Management Protocol) support.

• 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, subnet mask to 255.255.255.0 and DHCP server enabled with a
pool of 32 IP addressed starting at 192.168.1.33.

1.3 Applications for the Prestige

Here are some example uses for which the Prestige is well suited.

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 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 next.
