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.
Introduction to 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.

Getting To Know Your Prestige

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

1.1 Introducing the Prestige

Your Prestige integrates high-speed 10/100Mbps auto-negotiating LAN interface(s) 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. The Prestige is an ADSL router compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable by the Prestige for each standard are shown in the next table.
DATA RATE
STANDARD
ADSL
ADSL2
ADSL2+
The standard your ISP supports determines the maximum upstream and
downstream speeds attainable. Actual speeds attained also depend on the
distance from your ISP, noise, line quality, etc.
UPSTREAM DOWNSTREAM
832 kbps 8Mbps
3.5Mbps 12Mbps
3.5Mbps 24Mbps
By integrating DSL and NAT, the Prestige provides ease of installation and Internet access.
Models ending in “1”, for example P660R-61, denote a device that works over the analog telephone system, POTS (Plain Old Telephone Service). Models ending in “3” denote a device that works over ISDN (Integrated Synchronous Digital System). Models ending in “7” denote a device that works over T-ISDN (UR-2).
Only use firmware for your Prestige’s specific model. Refer to the label on the
bottom of your Prestige.
The web browser-based Graphical User Interface provides easy management.

1.2 Features of the Prestige

The following sections describe the features of the Prestige.
High Speed Internet Access
Your Prestige ADSL/ADSL2/ADSL2+ router can support downstream transmission rates of up to 24Mbps and upstream transmission rates of up to 3.5Mbps. Actual speeds attained depend on ISP DSLAM environment.
Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.
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.
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 computers on the LAN, which see only Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual computers.
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).
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface(s)
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.
Auto-Crossover (MDI/MDI-X) 10/100 Mbps Ethernet Interface(s)
These interfaces automatically adjust to either a crossover or straight-through Ethernet cable.
1-2 Getting To Know Your Prestige
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider.
Multiple PVC (Permanent Virtual Circuits) Support
Your Prestige supports up to 8 PVC’s.
ADSL Transmission Rate Standards
♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8 Mbps
downstream and 832 Kbps upstream.
♦ G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream.
♦ Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.lite (G992.2)).
♦ TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
♦ ATM Forum UNI 3.1/4.0 PVC.
♦ Supports up to 8 PVCs (UBR, CBR, VBR).
♦ Multiple Protocol over AAL5 (RFC 1483).
♦ PPP over AAL5 (RFC 2364).
♦ PPP over Ethernet over AAL5 (RFC 2516).
♦ RFC 1661.
♦ PPP over PAP (RFC 1334).
♦ PPP over CHAP (RFC 1994).
Protocol Support
♦ 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. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. 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.
♦ IP Alias
Getting To Know Your Prestige 1-3
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 (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.
♦ PPP (Point-to-Point Protocol) link layer protocol.
♦ Transparent bridging for unsupported network layer protocols.
♦ RIP I/RIP II
♦ IGMP Proxy
♦ ICMP support
♦ ATM QoS support
♦ MIB II support (RFC 1213)
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.
