    Introduction to the HotWire DSLAM What is the HotWire DSLAM? The HotWire Digital Subscriber Line Access Multiplexer (DSLAM) is a multiservices DSL platform that provides high-speed Internet or Intranet access over traditional twisted-pair telephone wiring. The DSLAM chassis houses DSL cards that interoperate with multiple types of HotWire Remote Termination Units (RTU) to deliver applications at multimegabit speeds in support of packet services over a Digital Subscriber Line (DSL) link.

  • Page 25: Understanding The Domain Types

    Introduction to the HotWire DSLAM Understanding the Domain Types Functionally, the HotWire DSLAM network model can be divided into: Features supporting customers Features integral to supporting customers are the DSL cards and HotWire RTUs. Features supporting overall system management The central point of access for overall system management is the MCC card. However, the features integral to supporting overall system management are also distributed throughout the HotWire DSLAM and the HotWire RTUs.

    Point-to-Point Protocol/High-level Data Link Control (PPP/HDLC) Packets transmitted over DSL links on an 8546 DSL card are encapsulated in PPP/HDLC frames. PPP/HDLC is not supported on the 8540 DSL card. Packets transmitted over LAN ports are encapsulated in Ethernet II MAC frames.

    Service Domain Features Internet Control Management Protocol (ICMP) In general, ICMP is supported. However, the options field is not reflected back if the HotWire DSLAM is the destination address (i.e., the HotWire DSLAM receives the data and then returns the packet without the options field).

  • Page 28: Scenario 2: With Proxy Arp

    WS1 sends a packet to Router A. Router A consults its routing table to determine the next hop address (i.e., router IP address) for WS2 because WS2 is on another network (135.1.0.0). Now that it knows the next hop address to Router B, Router A then ARPs for Router B.

    Components of the Network Model Overview The service and management domains logically comprise the network model. This chapter describes the components that comprise these domains. Service Domain Components The primary purpose of the service domain network is to provide IP routing of customer data between the Network Service Provider (NSP) and the end-user system (ES).
  • Page 34 Components of the Network Model The following illustration shows another internetworking configuration. This configuration has multiple end users connected to the HotWire RTU using a hub. The number of supported end-user systems depends on whether you use a host or structured subnetting. For more information, see Chapter 5, Allocation NOTE: This illustration does not apply to the 5171 PC NIC and 5216 RTU.

  • Page 41: Ip Address Allocation

    IP Address Allocation Overview IP addresses are assigned throughout the network model for components comprising both the service and management domains. This chapter describes the IP address allocation schemes for the components that make up the HotWire DSLAM network model. It also describes the naming convention used for the HotWire DSLAM system interfaces.

  • Page 42: Assigning Ip Addresses

    IP Address Allocation The following illustrates the logical interface naming convention. 10BaseT Interface to Management Network Assigning IP Addresses In the HotWire DSLAM network model, there are two distinct domains: a management domain a service domain Within the management domain, there are two subnets as described in Management Domain Components of two IP address allocation schemes can be followed: host addressing or structured subnet addressing.

  • Page 43: Host Addressing

    NOTE: Structured subnetting is supported on the 8546 DSL card and the 5446 RTU. It is not supported, however, on the 8540 DSL card and its corresponding RTUs on the DSL ports. Structured subnet addressing uses the following method: Within the service domain, the NSP would provision a subnet of its domain to a DSL card and all devices behind it.

  • Page 52: Ip Routing

    IP Routing Overview This chapter presents information regarding the theory behind the configuration of routes (static and dynamic) on the HotWire DSLAM, as well as examples. Both standard destination-based routes and source-based routes are described. Routing Table The routing table stores information about possible destinations for packets that are routed through the HotWire DSLAM.

  • Page 53: Static Routes For Static Ip Addressing

    IP Routing With destination-based routing, the destination address of the packet being sent is compared to the destination address entries in the routing table. The destination address could possibly match one or more of three types of addresses in the routing table. It could match a: Host route address (that is, a specific destination IP address) e.g., 135.1.3.5, Subnet route, e.g., 135.1.3.0, or Network route, e.g., 135.1.0.0...

  • Page 56: Dynamic Routes For Dynamic Ip Addressing

    Dynamic Routes for Dynamic IP Addressing Alternatively, NSPs can administer IP addresses to the end users dynamically (automatically) rather than statically (manually). The dynamic IP addressing feature consists of the following components: DHCP relay agent The DSL card in the DSLAM acts as a DHCP relay agent. The DHCP relay agent is an intermediary function between the end-user system and the DHCP server.

  • Page 57: How Does Dynamic Ip Addressing Work

    IP Routing Automatic dynamic access control The DSL card supports IP filters to validate user access to the NSP network. If the automatic dynamic access control feature is enabled, filters are configured automatically. The IP filters examine the IP source address of the upstream traffic to validate the end-user system’s IP address.
  • Page 58 1. The end-user system requests an IP address by broadcasting a DHCP request message to the DHCP server. 2. The DSLAM performs a DHCP relay by acting as a DHCP relay agent. The DHCP relay function of the DSLAM acts as an intermediary between the end-user system and the DHCP server, and works with DHCP servers that support structured subnetting.

  • Page 59: General Dhcp Relay Agent Configuration

    See the following section, Authentication Server Administrator For detailed information about the various DHCP relay screens, see the HotWire DSLAM for 8540 and 8546 DSL Cards User’s Guide. Also Appendix A, Configuration Worksheets record your network configurations for dynamic IP addressing.

  • Page 60: Radius Authentication

    RADIUS Authentication If the authentication server is a RADIUS server, an Access-Request message will have the following format: The user_name will be the end-user’s user ID as received by the DSLAM in the type 0 client ID field of the DHCP request. If the end-user request does not contain a user ID, the corresponding domain name is used as the user_name.

    IP Filtering Overview A filter is a useful mechanism and can be used to: Secure a network by implementing security rules (policies) Prevent unauthorized network access without making authorized access difficult. By default, filtering is not active on the HotWire DSLAM system. However, you can enable filtering to selectively filter source or destination packets being routed through the MCC or DSL cards.
  • Page 65 The dynamic access control feature is configurable on the DHCP Relay Servers screen. See Chapter 6 of the HotWire DSLAM for 8540 and 8546 DSL Cards User’s Guide for more information. You can create the following filter types: An input filter to prevent packets entering the DSL card through a specified interface from being forwarded.

    This chapter provides examples of how data packets are routed through the service and management domains. Packet Walk-Through Using an 8540 DSL Card Service Domain Packet Walk-Through To examine how data packets flow through the service domain, an example of ES1 issuing a ping to NSP1 will be used.
  • Page 75 4. After ES1 receives the ARP reply, it sends the packet to the MAC address of the 8540 DSL card. 5. Upon receiving this packet, the RTU forwards it to the 8540 DSL card over its DSL interface. 6. When the 8540 DSL card receives this packet, the 8540 DSL card consults its routing table to determine how to route the packet.

  • Page 76: Management Domain Packet Walk-Through

    6. The 8540 DSL card then consults its routing table to identify the next hop to forward the packet. Since a host route is defined for ES1 (route #2), the DSL interface is used as the next hop. 7. The 8540 DSL card then forwards the packet over the DSL port to that RTU.

  • Page 77: Management Domain Packet Walk-Through

    Packet Walk-Throughs When ES1 pings NSP1: 1. ES originates a packet addressed to 155.1.2.2. Because they are both on the 155.1 network, ES1 ARPs to map NSP1’s IP address into a MAC address. 2. The RTU receives the broadcast ARP request from ES1. 3.
