iv Information for Canadian Users
Information for Canadian Users
The Industry Canada label identifies certified equipment. This certification means that the equipment meets
certain telecommunications network protective, operation, and safety requirements. The Industry Canada
does not guarantee that the equipment will operate to a user's satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of
the local telecommunications company. The equipment must also be installed using an acceptable method
of connection. In some cases, the company's inside wiring associated with a single line individual service
may be extended by means of a certified connector assembly. The customer should be aware that the
compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility designated
by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions,
may give the telecommunications company cause to request the user to disconnect the equipment.
For their own protection, users should ensure that the electrical ground connections of the power utility,
telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution
may be particularly important in rural areas.
Caution
Users should not attempt to make such connections themselves, but should contact the appropriate electrical
inspection authority, or electrician, as appropriate.
Note
This digital apparatus does not exceed the class A limits for radio noise emissions from digital apparatus set
out in the radio interference regulations of Industry Canada.

What is DSL? xiii
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 VDSL?
VDSL is the next generation of DSL technology that offers a much higher bandwidth than most DSL
technologies. VDSL is the only feasible solution for bandwidth-demanding and video-rich applications such
as video-on-demand, high definition television, tele-medicine, surveillance systems and other switched video
services. VDSL supports both symmetric and asymmetric applications using existing copper wire (telephone
wire) and therefore saving the cost of using traditional T1/E1 service for small/medium-sized business and
residential users.

GETTING STARTED
This part covers Getting to Know Your Prestige and Hardware Installation.

Getting to Know Your VDSL Modem 1-1
Chapter 1
Getting to Know Your VDSL Modem
This chapter covers the key features and main applications of your Prestige.
1.1 Introducing the Prestige
The Prestige can be used for high-speed Internet access through a VDSL connection over the telephone
line. The Prestige supports data transmission speeds of 50 Mbps downstream and 30 Mbps upstream. The
actual rate depends on the copper category of your telephone wires, distance from the central office and the
type of DSL service you subscribe to. Its 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 using CLI (Command Line Interface) commands.
1.2 Features of the Prestige
The following features make the Prestige a complete and the flexible networking solution for most users.
High Speed Internet Access
The Prestige supports transmission speeds of up to 50 Mbps downstream and 30 Mbps upstream.
10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required. It enables fast data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.
Auto-crossover 10/100 Mbps Ethernet LAN
The LAN interfaces automatically adjust to either a crossover or straight-through Ethernet cable.
Protocols Supported
• TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
Encapsulation
The Prestige supports RFC-2684 (Multiprotocol Encapsulation over ATM Adaptation Layer 5 ).

Prestige 861 VDSL Modem
1-2 Getting to Know Your VDSL Modem
RFC 2684 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5).
The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based
multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual
circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.
Ease of Installation
Your Prestige is designed for quick, easy and intuitive installation. Its compact size and light weight make it
easy to position anywhere in your busy office.
1.3 Application Scenario for the Prestige
This section provides an example of how your Prestige can be used.

Connect the Prestige directly to the wall jack using a telephone wire (RJ-11 connector).
2.3.2 LAN 10/100M
The Prestige has four 10/100Mbps auto-negotiating, auto-crossover Ethernet ports. The LAN interface is
auto-crossover, so you may use a crossover cable or a straight-through Ethernet cable to connect your
Prestige to a computer/external hub.
