The Alcatel‑Lucent 7302 ISAM is a high-capacity IP access node designed to deliver ultra-broadband services primarily over copper infrastructure. Its 16-slot shelf architecture supports multi‑DSL line cards, enabling deployment of VDSL2, G.shdsl, ADSL2+, and multi‑DSL services with exceptional density and flexibility.
The platform is optimized for broadband central office deployments, offering up to 48 VDSL2 ports per card, along with support for multi-ADSL, POTS, SHDSL, Ethernet subscriber interfaces, and integrated inline splitters—all within a high-performance chassis.
Later software releases utilize a Gigabit Ethernet switching fabric, with controller options supporting up to 100 Gb/s throughput. This allows multiple GE uplinks per shelf and ample backhaul bandwidth, ensuring support for high-speed services across densely populated service areas.
Designed to make full use of existing copper networks or to be combined with fiber front-end modules, the 7302 ISAM provides a cost-effective, scalable platform for delivering high bit-rate broadband services. Depending on line quality and distance, the system can support speeds of 100 Mb/s and beyond per subscriber.

The Alcatel 7302 ISAM is a high-capacity, modular IP access platform designed to support a wide range of broadband technologies over copper infrastructure. It features a 16-slot chassis that can be populated with a variety of line cards supporting VDSL2, ADSL2+, G.SHDSL, POTS, and Ethernet subscriber interfaces. Each VDSL2 line card supports up to 48 subscriber ports, enabling dense broadband access from a single node.
The platform incorporates a high-performance Gigabit Ethernet switching fabric, with controller cards offering up to 100 Gb/s of switching capacity. Depending on configuration, each shelf can support multiple Gigabit Ethernet uplinks or higher-capacity links for traffic aggregation and connection to the core network. This allows the system to accommodate increasing bandwidth demand while maintaining low latency and high service reliability.
Subscriber services are delivered using IP protocols, and the 7302 ISAM is fully compatible with IPv4 and IPv6, making it suitable for modern IP-based networks. It supports standard Layer 2 and Layer 3 features, VLAN tagging, QoS enforcement, multicast handling, and subscriber authentication, enabling delivery of voice, video, and high-speed data services in a triple-play environment.
The system is designed for central office installation and conforms to telecom-grade requirements, including NEBS and ETSI standards. It supports redundant control and power modules, ensuring high availability and resilience. Each module is hot-swappable, allowing for live maintenance and scalability without service interruption.
The 7302 ISAM also supports remote management and provisioning through standard protocols such as SNMP, CLI, and integration with Alcatel-Lucent’s service management systems. Diagnostic tools, real-time performance monitoring, and alarm reporting are built in to facilitate proactive maintenance and reduce operational costs.
