Alcatel-Lucent 244-2091-005 High Density Digital Line Card V1.5 – Pack Circuit
The Alcatel-Lucent 244-2091-005 High Density Digital Line Card V1.5 is a powerful access line card designed for next-generation digital subscriber line (DSL) aggregation platforms. Part of the company's renowned DSLAM (Digital Subscriber Line Access Multiplexer) family, this circuit pack enables service providers to deliver ultra‑fast broadband, triple‑play services, and advanced vectoring capabilities to residential and business subscribers.
Product Architecture
This high-density line card supports up to 96 subscriber ports per card, leveraging advanced DSP technology to provide VDSL2 (including Profile 35b) and ADSL2+ support with backward compatibility. The V1.5 revision introduces enhanced vectoring co‑channel cancellation, significantly reducing crosstalk and boosting achievable data rates by up to 40% compared to previous generations. The pack circuit integrates a powerful packet processor for QoS classification, traffic shaping, and VLAN handling, ensuring optimal performance for latency-sensitive applications such as IPTV and online gaming.
The card interfaces with the system backplane via a high-speed serial bus, supporting line rates up to 10 Gbps for uplink aggregation. It also features built-in test capabilities for loop diagnostics, metallic line testing (MLT), and remote endpoint interrogation.

Key Features and Benefits
High port density reduces chassis footprint and per‑subscriber power costs.
Advanced vectoring eliminates crosstalk, enabling higher rates over longer loops.
Dynamic spectrum management (DSM) optimises power allocation to reduce interference.
Hardware‑assisted IP multicast for efficient IPTV distribution.
Comprehensive diagnostics including SELT and DELT for proactive fault detection.
Deployment and Integration
This line card is intended for use in Alcatel-Lucent's 7330 ISAM (Intelligent Services Access Manager) and 7360 ISAM FX platforms. It seamlessly integrates with existing outside plant infrastructure, supporting both central office and street cabinet deployments. The card's hot‑swap capability enables field replacement without service interruption. Management is performed via the Alcatel-Lucent 5520 AMS (Access Management System), offering unified provisioning, performance monitoring, and alarm correlation.
Service providers can deploy this card to deliver symmetrical high‑speed connections for business VPNs or asymmetrical profiles for residential internet. The V1.5 revision includes optimised low‑power modes for green networking, reducing energy consumption during off‑peak hours.
Performance and Quality of Service
With its robust queuing and scheduling mechanisms, the line card supports strict priority and weighted fair queuing, ensuring that voice and video traffic receive guaranteed bandwidth. It also supports per‑port shaping and policing, enabling service level agreement (SLA) enforcement. Built‑in hardware counters provide real‑time statistics on errored seconds, CRC errors, and signal-to‑noise margins, facilitating rapid troubleshooting.
Conclusion
The Alcatel-Lucent 244-2091-005 High Density Digital Line Card V1.5 is a mature, high‑capacity solution for modern broadband access networks. Its combination of density, vectoring performance, and robust feature set makes it a preferred choice for operators upgrading to gigabit‑capable DSL infrastructures.
