DSLAM

A DSLAM (Digital Subscriber Line Access Multiplexer) is an integrated hardware and software system that enables access to broadband services and telephone calls over a single pair of copper wires.
DSLAM delivers high-speed data transmission over existing copper telephone lines, separating voice-frequency signals from high-speed data traffic.
DSLAM controls and routes digital subscriber line (xDSL) traffic between the subscriber's end-user equipment and the network service provider's network.
DSLAM aggregates connections from many customers onto a single, high-capacity connection to the Internet.

AN-2000 IB Solution

Offers unlimited scalability, building out the network as needed with a modular, high-density architecture that scales from 24 to 2,424 subscribers per system.
Provides an open interface, interoperating with third-party gear and networks as needed, and supporting multiple xDSL standards.
Enables new revenue-generating services, such as IP multicasting for video and value-added services, and delivers always-on broadband data and video, high-speed Internet access, VPNs, distance learning, and enterprise networking.
Offers high-speed remote access, providing satellite-to-headquarters connectivity for business customers with an economical high-speed LAN-interface solution.

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.
