The Alcatel 7302 ISAM XD (Extreme-Density) is a high-capacity, IP-based broadband access platform engineered for ultra-dense deployments in central office environments. It is designed to deliver next-generation broadband services over copper and fiber using a modular, scalable architecture.
This version of the ISAM series separates the line termination and splitter functions into distinct subracks, allowing operators to scale efficiently while maintaining operational flexibility. With the ability to support up to 3,456 splitterless DSL lines per node, the XD platform is ideal for high-density residential and business broadband delivery.
The system supports a wide range of access technologies, including VDSL2, ADSL2+, SHDSL, and Ethernet, enabling providers to meet diverse service needs across legacy and modern network environments. Each chassis supports high-density line cards with up to 72 ports per card, and its switching fabric allows for 24 Gb/s to 100 Gb/s throughput, ensuring sufficient bandwidth for current and future service demands.
Designed with reliability and service continuity in mind, the Alcatel 7302 ISAM XD features redundant controllers and power supplies, hot-swappable modules, and full support for in-service upgrades. It is optimized for delivering triple-play services such as IPTV, VoIP, and high-speed data, backed by advanced QoS, VLAN handling, multicast support, and subscriber management.
This platform is well-suited to large-scale broadband deployments where space, performance, and flexibility are critical. It supports centralized provisioning and remote management, allowing operators to maintain control and visibility across complex network topologies.
Carritech offers complete support for the 7302 ISAM XD, including spare parts, hardware servicing, and technical consultation to help operators maintain and extend the lifecycle of their broadband infrastructure.

The Alcatel 7302 ISAM XD is designed for ultra-dense broadband access deployments, with a scalable architecture that separates line termination and splitter functions into dedicated subracks. This modular layout allows for highly efficient use of space, with support for up to 3,456 DSL lines per node in splitterless configurations. Each subrack can accommodate multiple high-density line cards, including 72-port VDSL2, ADSL2+, SHDSL, and Ethernet modules.
The system includes a high-performance switching backplane with a capacity ranging from 24 Gb/s to 100 Gb/s, depending on the controller card configuration. Multiple Gigabit Ethernet uplinks are supported for high-speed aggregation and backhaul, ensuring the platform can handle modern bandwidth demands and triple-play services without bottlenecks.
The 7302 ISAM XD supports a wide range of subscriber services, with advanced features such as VLAN tagging, Quality of Service (QoS) classification, multicast replication, and subscriber session management. These capabilities allow operators to offer differentiated services for voice, video, and data with guaranteed performance levels.
It is fully compliant with telecom standards for central office deployment, including NEBS and ETSI, and is engineered for carrier-grade reliability. The chassis supports redundant controllers and power supplies, with hot-swappable components that enable maintenance and upgrades without service interruption.
The system is managed via standard interfaces such as CLI and SNMP, and integrates with centralized network and service management tools. Built-in diagnostics, alarm handling, and real-time performance monitoring simplify operations and support efficient troubleshooting and lifecycle management.
Designed for long-term scalability and flexibility, the Alcatel 7302 ISAM XD allows operators to expand service offerings while minimizing operational overhead and infrastructure costs.
