    HAPTER NTRODUCTION 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.

  • Page 16: Features And Benefits

    NTRODUCTION 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.
  • Page 17 EATURES AND ENEFITS • 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 •...

  • Page 18: Networking Concepts

    NTRODUCTION 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.

  • Page 19: Route Determination

    ETWORKING ONCEPTS 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.

  • Page 20: Routing

    NTRODUCTION 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.

  • Page 21: Network Applications

    ETWORK PPLICATIONS 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.

  • Page 22: Accessing The Internet

    NTRODUCTION ADSL Router Router 10/100 Mbps Ethernet LAN 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.
  • Page 23 ETWORK PPLICATIONS 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.

    PPENDIX LOSSARY 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.
  • Page 104 LOSSARY 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...

  • Page 105: Dynamic Routing

    LOSSARY 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.
  • Page 106 LOSSARY 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.

  • Page 107: Multiprotocol Encapsulation

    LOSSARY 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 straight-through cable.
  • Page 108 LOSSARY 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.
  • Page 109 LOSSARY 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).

  • Page 110: Virtual Circuit

    LOSSARY 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.
  • Page 111 LOSSARY 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.
