Introduction

About the 5600 Series DSL Router

The SpeedStreamTM 5600 Series Ethernet to ADSL router provides
ATM-based network access for home users, telecommuters, or remote
offices and are equipped with one Ethernet port and one Asymmetric
Digital Subscriber Line (ADSL) port. These internet sharing devices use
Discrete Multitone (DMT) technology to s et data transmit rates. When the

unit is first powered on, it will “train” the line to ge t the best data
transmission rate.

The 5600 Series internet sharing device can be used as either a router or a
bridge. It is configured t o operate as a router when it is first installed. To
use it as a bridge, you must log into the router and change the mode to

bridge mode.

Router Mode (factory default mode) :

• Provides IP routing between a Local Area Network (LAN) and the Wide

Area Network (WAN).

• Can be configured to use

• PPP (factory default)

• RFC 1483 routed encapsulation

• RFC 1483 bridged encapsulation

Bridge Mode:

• Provides high-speed connectivity from an Ethernet LAN to the WAN

over the ADSL connection

• Uses RFC 1483 bridged encapsulation over ATM

Routing vs. Bridging

What is the difference between routing and bridging?

• Bridges determine where to send data packets between local area

network (LAN) segments based on the MAC address of the sending and
receiving computers or devices (nodes) on the network. The MAC
address is a unique identifier that is programmed into the network

interface card installed in a network node. Bridging is a simple
transmission scheme and th ere is little software manage ment invo lved in
the sending of packets. Packets are simply forwarded from one node to
the next.

• Routers are much more complex than bridges. Routers send packets

from node to node based on IP addresses. An IP address can be viewed
as a modifiable identifier that is mapped to the MAC address of network
node. The IP address of a node may change dynamically or by user
configuration. Therefore, there are protocols and databases on the
network that must keep track of the IP address assignments for the
nodes on the local area network. Other features of a router allow you to
restrict the types of data packets that are allowed onto your local area
network from the wide area network (WAN) and vice versa.

Where and Why to Use the
Router

The 5600 Series router supports multiple or individual users at a remote,
small office or in a home office that is connected via ADSL to a central
office or network service provider.

The drawing below shows several computers (network nodes) attached via

Ethernet cables to an Ethernet hub at the end-user’s office. The hub is
connected to the 5600 Series router. The device is connected to the outside
world (internet) via a telephone jack that has been configured to support
DSL service.

Installation Requirements

To successfully install the 5600 series router, you will need the following:

• A computer equipped with an Ethernet network interface card OR an

Ethernet hub

• A DSL-ready telephone line installed at the installatio n site

• If you want to configure the router via the serial port before placing it

into service on a network, you will need a co mputer that has terminal
emulation software such as Microsoft HyperTerminal or ProComm.

Package Contents

Your package should contain the items listed below. If anything is missing
or damaged, please contact the dealer from whom the equipment was
purchased.
