COMPACT ROUTER ADSL
1.3 Features of the Compact Router ADSL
The following sections describe the features of the ADSL Router.
High Speed Internet Access: The ADSL Router can support downstream
transmission rates of up to 8Mbps and upstream transmission rates of 832 Kbps.
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 ADSL Router 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-negotiation Ethernet/Fast Ethernet Interface: This autonegotiation feature allows the ADSL Router 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.
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 client.
Multiple PVC (Permanent Virtual Circuits) Support
The ADSL Router supports up to 8 PVC’s.
ADSL 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.994.1
and G.996.1 (for ISDN only); G.991.1;G.lite (G992.2)).Supports OAM F4/F5 loopback, AIS and RDI OAM cells.ATM Forum UNI 3.1/4.0 PVC.Supports up to 8
PVCs (UBR, CBR, VBR).Multiple Protocols over AAL5 (RFC 1483).PPP over
AAL5 (RFC 2364).PPP over Ethernet (RFC 2516).
A02-RA110 Pag. 2
COMPACT ROUTER ADSL
DHCP Support: DHCP (Dynamic Host Configuration Protocol) allows individual
clients (computers) to obtain TCP/IP configuration at start-up from a centralized
DHCP server. The ADSL Router 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 ADSL Router 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: IP Alias allows you to partition a physical network into logical networks
over the same Ethernet interface. The ADSL Router supports three logical LAN
interfaces via its single physical Ethernet interface with the ADSL Router 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.
Protocol Support: PPP (Point-to-Point Protocol) link layer protocol.PPP over
PAP (RFC 1334).PPP over CHAP (RFC 1994).RIP I/RIP II.IGMP Proxy,ICMP
support,MIB II support (RFC 1213),PPPoE feature,PPPoE idle time out,PPPoE
dial on demand.
Networking Compatibility: The ADSL Router is compatible with major ADSL
DSLAM (Digital Subscriber Line Access Multiplexer) providers.
Multiplexing:
Encapsulation: The ADSL Router series supports PPPoA (RFC 2364 - PPP over
ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM, MAC encapsulated
routing (ENET Encapsulation) as well as PPP over Ethernet (RFC 2516).
Network Management: Embedded Web Configurator,CLI (Command Line
Interpreter),SNMP manageable,DHCP Server/Client,Built-in Diagnostic Tools.
Syslog, TFTP/FTP server, firmware upgrade and configuration backup/support
supported.
Diagnostics Capabilities: The ADSL Router can perform self-diagnostic tests.
These tests check the integrity of the following circuitry:
The ADSL Router supports VC-based and LLC-based multiplexing.

1.4 Applications for the ADSL Router
Here are some example uses for which the ADSL Router is well suited.
1.4.1 Internet Access
The ADSL Router is the ideal high-speed Internet access solution. The Compact
Router ADSL Router 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 (for example, T1, OC3,
DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for
ADSL.

Chapter 4: Wizard Setup
This chapter provides information on the Wizard Setup screens in the web
configurator.
4.1 Wizard Setup Introduction
Use the Wizard Setup screens to configure your system for Internet access
settings and fill in the fields with the information in the Internet Account
Information table of the Compact Guide or Read Me First. Your ISP may have
already configured some of the fields in the wizard screens for you.
4.2 Encapsulation
Be sure to use the encapsulation method required by your ISP. The ADSL Router
supports the following methods.
4.2.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only
implemented with the IP network protocol. IP packets are routed between the
Ethernet interface and the WAN interface and then formatted so that they can be
understood in a bridged environment. For instance, it encapsulates routed
Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a
gateway IP address in the Ethernet Encapsulation Gateway field in the second
wizard screen. You can get this information from your ISP.
4.2.2 PPP over Ethernet
PPPoE provides access control and billing functionality in a manner similar to
dial-up services using PPP. The ADSL Router bridges a PPP session over
Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC
(Permanent Virtual Circuit) which connects to ADSL Access Concentrator where
the PPP session terminates. One PVC can support any number of PPP sessions
from your LAN. For more information on PPPoE, see the appendix.
4.2.3 PPPoA
PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). It
provides access control and billing functionality in a manner similar to dial-up
services using PPP. The ADSL Router encapsulates the PPP session based on
A02-RA110 Pag. 19
COMPACT ROUTER ADSL
RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the
Internet Service Provider's (ISP) DSLAM (digital access multiplexer). Please refer
to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more
information on PPP.
4.2.4 RFC 1483
RFC 1483 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.
4.3 Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is
carrying. Be sure to use the multiplexing method required by your ISP.
4.3.1 VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific
virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be
dominant in environments where dynamic creation of large numbers of ATM VCs
is fast and economical.
4.3.2 LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information
being contained in each packet header. Despite the extra bandwidth and
processing overhead, this method may be advantageous if it is not practical to
have a separate VC for each carried protocol, for example, if charging heavily
depends on the number of simultaneous VCs.
4.4 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel
Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255
and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM
traffic). Please see the appendix for more information.
4.5 Wizard Setup Configuration: First Screen
