xx Preface
Prestige 791R G.SHDSL Router
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 G.SHDSL?
G.SHDSL (Single-pair High-speed Digital Subscriber Line) is a symmetrical, bi-directional DSL service that
operates on one twisted-pair wire and provides data rates up to 2.3 Mbits/sec. (The “G.” in “G.SHDSL” is
defined by the G.991.2 ITU (International Telecommunication Union) state-of-the-art industry standard).

Chapter 1
Getting to Know Your G.SHDSL Router
This chapter covers the key features and main applications of your Prestige.
The Prestige 791R Router can be used for high-speed LAN-to-LAN connections or Internet access through
a G.SHDSL connection over the telephone line. You can use your Prestige for either IP routing or bridging
depending on your ISP (Internet Service Provider) configuration.
1.1 Features of the Prestige
The following features make the Prestige a complete and the flexible networking solution for most users.
Scalability
One of the best features of G.SHDSL service is its scalability. You can increase the capacity of the Internet
connection (within certain distance limitations) without changing your ISP or purchasing new equipment.
G.SHDSL’s high symmetrical speeds are ideal for applications like web hosting and videoconferencing as
well as the two-way data traffic needs of businesses.
Symmetrical High Speed Internet Access
The Prestige 792H can support symmetrical transmission speeds of up to 2.3 Mbps. For NSP’s (Network
Service Provider) convenience, the Prestige also supports rate management depending on distance and
service charges.
The table below lists the transmission speeds available on the Prestige.
SUPPORTED TRANSMISSION SPEEDS
Min (Kbps) Max (Kbps)
SDSL
G.HDSL (G.991.2)
SNMP (Simple Network Management Protocol – versions 1 and 2)
SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your Prestige supports SNMP agent functionality that allows a manager station to manage
and monitor the Prestige through the network.
Getting to Know Your G.SHDSL Router 1-1
72 136
200 2312
Prestige 791R G.SHDSL Router
SNMP is only available if TCP/IP is configured on your Prestige.
IP Multicast
Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management
Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236);
the Prestige supports both versions 1 and 2.
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.
IP Policy Routing
IP Policy Routing provides a mechanism to override the default routing behavior and alter packet
forwarding based on the policies defined by the network administrator.
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.
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).
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is available on more platforms.
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 built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to other systems that support the DHCP client. The Prestige can now also act as a surrogate DHCP
server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.

Prestige 791R G.SHDSL Router
Encapsulation
The Prestige supports PPPoE, PPP over ATM (RFC-2364), Multiple Protocol over ATM (RFC-1483) and
ENET ENCAP.
SUA for Single-IP Address Internet Access
The Prestige’s SUA (Single User Account, equivalent to NAT) feature allows multiple user Internet access
for the cost of a single ISP account and allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently. SUA supports popular Internet applications such as MS traceroute, CuSeeMe,
IRC, ICQ, RealAudio, VDOLive, Quake and PPTP. No extra configuration is needed to support these
applications. SUA address mapping can also be used for other LAN-to-LAN connections.
Universal Plug and Play (UPnP)
Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically join a
network, obtain an IP address and convey its capabilities to other devices on the network.
Full Network Management
• Menu driven SMT (System Management Terminal) management
• SNMP manageable
• Web Configurator
Upgrade Firmware via LAN
In addition to the direct console port connection, the Prestige supports the up/downloading of firmware and
configuration file over the LAN.
Packet Filtering
Packet filtering blocks unwanted traffic from entering/leaving your network.
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.
Multiple PVC (Permanent Virtual Circuits) Support
Your Prestige supports up to 12 PVC’s.
All-in-one Console and Auxiliary Port
Set the CON/AUX switch to the “CON” side when using the CON/AUX port as a regular console port for
local device configuration and management. Set this switch to the “AUX” side when using the CON/AUX
port as an auxiliary dial-up WAN connection.
