    Subscriber Isolation

    • The ISM provides subscriber isolation at both layer two and layer three, preventing cross-talk between DSL subscribers and forwarding all subscriber traffic to the aggregation router.
    • At layer two, the AN-2000 IP-DSLAM ensures that two subscribers cannot communicate with each other without going through the upstream aggregation router, even if they are in the same bridge group.
    • At layer three, VRDs provide subscriber isolation, applying priority queuing and traffic policing to each VLAN to ensure conformance to the SLA provided to the VPN subscribers.

    Network Architecture

    • The AN-2000 IP-DSLAM chassis consists of two controller slots and 16 network/line module slots for user data traffic.
    • The slots can contain three types of modules: Internet Concentration Modules (ICM), IP Service Modules (ISM), and Line Card Modules (L/C).
    • The ICM provides Ethernet switching capability, aggregating upstream traffic from DSL line cards to the WAN uplink and segregating downstream traffic from the WAN to DSL line cards.
    • The ISM provides B-RAS functionality and WAN uplink through its Ethernet and ATM interfaces.
    • The L/C comprises 24 DSL ports for DSL connections to subscriber CPE.

    Network-Layer VPNs

    • The ISM supports three types of network-layer VPNs: L2TP, IP-IP, and IP-GRE.
    • Subscriber traffic is transported by VPN tunnels when it leaves the DSLAM.
