CHAPTER 1 INTRODUCTION Congratulations on your purchase of the Barricade 2-Port Broadband Router with built-in ADSL Modem. We are proud to provide you with a powerful yet simple communication device for connecting your PC to the Internet. The Barricade is an Asynchronous Digital Subscriber Line (ADSL) network device that provides high-speed Internet access over existing phone lines. It supports both full-rate Discrete Multi-Tone (G.
INTRODUCTION services requiring guaranteed Quality of Service (QoS). The Barricade enables true telecommuting for the first time. It also provides multiprotocol encapsulation for bridging Windows NetBEUI and Novell’s IPX protocols directly to a remote site for complete access to corporate resources, or for routing TCP/IP traffic for Internet connections.
FEATURES AND BENEFITS • Supports pass-through for three of the most commonly used Virtual Private Network (VPN) protocols – PPTP, L2TP, and IPSec • Security protocols, including Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol (CHAP) • Always-on digital connection eliminates dial-up delays, and transparent reconnection when initiating a network request • Concurrent data and voice over a single connection (needs splitter for G.dmt but not G.
INTRODUCTION Networking Concepts ADSL Digital Subscriber Line (DSL) technology transmits both data and voice over ordinary telephone lines. Signals above 4 kHz are cut off in normal telephone communications as noise, so DSL uses this spectrum to transmit data. Since Internet users and people telecommuting from home normally download more data than they upload, Asymmetric Digital Subscriber Line (ADSL) is the preferred choice.
NETWORKING CONCEPTS Data flows are broken up into fixed length cells, each of which contains a Virtual Path Identifier (VPI) that identifies the path between two nodes, and a Virtual Circuit Identifier (VCI) that identifies the data channel within that virtual path. Each virtual circuit maintains a constant flow of cells between the two end points. When there is no data to transmit, empty cells are sent. And when data needs to be transmitted, it is immediately inserted into the cell flow.
INTRODUCTION Routing If ATM Protocol Encapsulation is set for PPP/ATM or IP/ATM, the router will forward incoming IP packets and use RIP 2 for routing path management if enabled. The router supports both static routing and dynamic routing. • Static routing requires routing information to be stored in the router, either manually or when a connection is set up, by an application outside the router.
NETWORK APPLICATIONS Network Applications The Barricade can be configured as a bridge for making a transparent connection to a remote site, or as a router for accessing the Internet. These applications are briefly described in the following sections. Accessing a Remote Site The Barricade can be configured to act as a transparent bridge between a local PC or LAN attached to the Ethernet port and a remote site across the ADSL link.
INTRODUCTION ADSL Router 10/100 Mbps Ethernet LAN Router 10/100 Mbps Ethernet LAN Figure 1-1. Transparent Bridged Network Accessing the Internet To access the Internet, which uses TCP/IP protocols exclusively, the Barricade must be configured to function as a router. One interface is the port attached to a local Ethernet LAN (or directly to a host PC with an Ethernet adapter), while the other is the ATM transport service running on the DSL port.
NETWORK APPLICATIONS When the system is powered on, the Barricade builds its own routing database according to previous static routing entries, and/or collects routing information from adjacent routers through RIP 2 protocol. RIP-1 is generally supported by all routers, but RIP 2 carries more information which allows the Barricade to make better choices on the most appropriate path to a remote network.

CHAPTER 2 INSTALLATION Before installing the Barricade, verify that you have all the items listed under “Package Contents.” If any of the items are missing or damaged, contact your local distributor. Also be sure that you have all the necessary cabling before beginning the installation. After installing the Barricade, refer to the Web-based configuration program (see Chapter 3) to learn how to configure the router.
INSTALLATION Hardware Description The Barricade provides a high-speed Asynchronous Digital Subscriber Line (ADSL) that connects to a remote site (via bridging) or to the Internet (via routing). It transports data over standard telephone wire at full-rate ADSL (G.dmt: 8 Mbps downstream, 640 Kbps upstream) or splitterless ADSL (G.lite: 1.5 Mbps downstream, 512 Kbps upstream) connection speeds.
HARDWARE DESCRIPTION LED Operation USB Activity Description On: The Barricade is in USB configured state and driver is loaded Off: The Barricade is NOT in USB configured state or driver is not loaded Slow blink: The Barricade flash memory is corrupt or flash memory is being updated.
INSTALLATION System Requirements You must have access to an ADSL network that meets the following minimum requirements: 2-4 • ADSL service from your local telephone company or Internet Service Provider (ISP), or access to an ADSL Digital Subscriber Line Access Module (DSLAM) at your local site. • PC configured with a fixed IP address or using dynamic IP address assignment via DHCP, as well as a Gateway server address and DNS server address from your service provider or network administrator.
CONNECT THE SYSTEM Connect the System Phone Line Configuration Installing a Full-rate Connection If you are using a full-rate (G.dmt) connection, your service provider will attach the outside ADSL line to a data/voice splitter. In this case you can connect your phones and computer directly to the splitter as shown below: Plain Old Telephone System (POTS) Residential Connection Point (NID) Voice Splitter Data ADSL Router or Ethernet hub or switch Figure 2-2.
INSTALLATION Installing a Splitterless Connection If you are using a splitterless (G.lite) connection, then your service provider will attach the outside ADSL line directly to your phone system.
CONNECT THE SYSTEM Connect the ADSL Line Run standard telephone cable from the wall jack providing ADSL service to the ADSL port on your Barricade. When inserting an RJ-11 plug, be sure the tab on the plug clicks into position to ensure that it is properly seated. If you are using splitterless ADSL service, be sure you add low-pass filters between the ADSL wall jack and your telephones. (These filters pass voice signals through but filter data signals out.
INSTALLATION Notes: 1. Use 100-ohm straight-through shielded or unshielded twisted-pair cable with RJ-45 connectors at both ends for all connections. Use Category 3, 4, or 5 for 10 Mbps connections, or Category 5 for 100 Mbps connections. 2. Make sure each twisted-pair cable does not exceed 100 meters (328 feet). Warning: Do not plug a phone jack connector into any RJ-45 port. This may damage the Barricade. Use only twisted-pair cables with RJ-45 connectors that conform with FCC standards.
CHAPTER 3 WEB-BASED MANAGEMENT Web-Based Configuration and Monitoring The ADSL Barricade provides an embedded HTTP Web agent. This agent can be accessed by any computer on the network using a Java-supported Web browser (including Internet Explorer 4.0 or above, and Netscape Navigator 4.0 or above).

APPENDIX D GLOSSARY 10BASE-T IEEE 802.3 specification for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTP cable. 100BASE-TX IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTP cable. Asymmetric Digital Subscriber Line (ADSL) ADSL allows more data to be sent over existing copper telephone lines than analog or ISDN technologies. ADSL supports data rates up to 8 Mbps downstream rate and up to 640 Kbps upstream.
GLOSSARY Bridging A device that connects two LANs, or two segments of the same LAN. Unlike routers, bridges are protocol-independent. They simply forward packets without analyzing and re-routing messages. Consequently, they may be faster than routers, but are less versatile. Challenge-Handshake Authentication Protocol (CHAP) A type of authentication in which the authentication agent (that is, the router) sends the client a key to use to encrypt the user name and password.
GLOSSARY Dynamic Routing Dynamic routing uses a routing protocol to exchange routing information with neighboring routers on the network. It calculates routing tables based on a given metric, such as least number of hops or shortest path. It can respond to changes in the status or traffic on the network, re-routing traffic as required.
GLOSSARY G.lite A standard that defines the more economical splitterless ADSL connection that transmits data at up to 1.5 Mbps downstream and 512 Kbps upstream. This ADSL option can be installed without an on-site visit by the service provider. IEEE 802.3 Defines carrier sense multiple access with collision detection (CSMA/CD) access method and physical layer specifications. IEEE 802.3u Defines CSMA/CD access method and physical layer specifications for 100BASE-TX Fast Ethernet.
GLOSSARY Media Access Control (MAC) A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes. Media Dependent Interface (MDI) The IEEE standard for the UTP interface to twisted-pair Ethernet. MDI defines a straight-through pin assignment that allows you to connect the router to any workstation or server that has a properly installed network adapter card using the supplied crossover cable.
GLOSSARY almost arbitrary number of connections is multiplexed using TCP port information. Password Authentication Protocol (PAP) A basic form of authentication, in which a user’s name and password are transmitted over a network and compared to a table of name-password pairs. Permanent Virtual Circuit A virtual network circuit that is permanently available. Ping A utility used to determine whether a specific IP address is accessible.
GLOSSARY Protocol Multiplexing See Multiprotocol Encapsulation Quality of Service (QoS) A network protocol used to specify a guaranteed throughput level. This protocol is often used by ATM providers to guarantee their customers a minimum end-to-end latency. Rate Adaptive ADSL (RADSL) An ADSL service that automatically adjusts the transmission rate depending on line quality and loading to ensure data quality (such as, keeping within a maximum error rate).
GLOSSARY Routing Routing forwards incoming IP packets using statically defined routes or a dynamic routing protocol such as RIP 2. Routing Information Protocol (RIP) A protocol that specifies how routers exchange routing table information. Splitter A hardware device used in G.dmt to split the data and voice traffic before passing it on to the network and phone system.
GLOSSARY Virtual Host A network device, such as this router, or a server configured to perform Network Address Translation (NAT). Virtual Path An ATM network connection between two nodes that spans across a series of routers or Layer-3 switches. Virtual Server Transparently redirects specific service requests (such as Web or FTP) to a dedicated local server.
