En Alcatel 7302 ISAM FD (Fully-Dense) is a high-capacity IP access node featuring a robust 18-slot chassis architecture, optimized for delivering ultra-broadband services over copper (VDSL2 and Multi-DSL) or fiber. Designed for carrier-grade performance in central office and aggregation sites, the FD variant offers maximum line density and flexible media integration.
Supporting a combination of subscriber access and splitter modules, the 7302 ISAM FD can host up to 16–18 line cards—including high-density DSL cards (48-port VDSL2, 72-port ADSL, SHDSL, POTS, or Ethernet)—allowing operators to scale up to 1,296 subscriber lines per chassis using 72-port modules.
The platform is equipped with a controller/backplane that supports optional high-throughput Ethernet connectivity—either 24 Gb/s or upgraded to 100 Gb/s, enabling multiple Gigabit Ethernet backhaul links and ensuring sufficient switching capacity for bandwidth-intensive services.
With integrated DSL line management, IP subscriber aggregation, and advanced VLAN/QoS processing, the 7302 FD supports triple-play services including IPTV, VoIP, and high-speed data. It also supports in-service expansion and line-card mix flexibility, making it ideal for both incumbent operators and new deployments.
Carritech offers comprehensive support for this platform, providing spare parts, hardware servicing, and technical support to extend operational life and ensure continued reliability.

En Alcatel 7302 ISAM FD is a high-capacity IP access platform built for ultra-broadband service delivery over copper and fiber. It features an 18-slot chassis, with space for up to 16 high-density line cards and two controller or splitter modules, depending on the configuration. Each chassis supports a mix of VDSL2, ADSL2+, SHDSL, POTS, and Ethernet interfaces, with line cards offering up to 72 ports per card, allowing for a total of 1,296 subscriber ports in a single shelf.
The system is powered by a high-performance switching backplane capable of handling 24 Gb/s in the standard version or up to 100 Gb/s in enhanced configurations. This switching fabric supports multiple Gigabit Ethernet uplinks, enabling flexible and high-throughput connectivity to the core network.
Subscriber traffic is managed with full IP routing and aggregation capabilities, supporting advanced features such as VLAN tagging, Quality of Service (QoS) enforcement, multicast streaming, and subscriber authentication. These capabilities make the platform well-suited for triple-play service delivery, including high-speed internet, IPTV, and VoIP.
The ISAM FD chassis is designed for central office deployment, compliant with ETSI and NEBS standards, and includes options for redundant power supplies and controller modules to ensure high availability. All major components, including line cards and controllers, are hot-swappable, allowing maintenance or expansion without service interruption.
The system is managed using standard protocols such as SNMP and CLI, and integrates with Alcatel-Lucent’s broader service and network management suites. Built-in diagnostics and alarm reporting allow operators to monitor performance and rapidly respond to faults.
