En Alcatel ASAM ATM A-7300 HD is a high-density Access Multiplexer designed to deliver broadband services over legacy copper infrastructure using Asynchronous Transfer Mode (ATM) technology. Engineered for scalability and reliability, the A-7300 HD serves as a central element in Alcatel’s Access Services Node (ASAM) portfolio, providing network operators with a robust platform for DSL-based service delivery.
Supporting a wide range of DSL variants—including ADSL, ADSL2+, and VDSL—the A-7300 HD enables efficient deployment of high-speed internet, voice, and multimedia services to residential and business subscribers. Its modular architecture and advanced management capabilities make it a flexible choice for service providers looking to expand or modernize their broadband access networks.
Whether integrated into urban deployments or rural infrastructure rollouts, the Alcatel A-7300 HD remains a trusted solution for bridging the gap between core network infrastructure and end-user connectivity.
Supports up to 896 ADSL lines per chassis using high-density line cards, enabling efficient use of rack space and reducing deployment costs.
Compatible with ADSL, ADSL2, ADSL2+, and VDSL standards, allowing flexible deployment across various service requirements and infrastructure conditions.
Built-in ATM switching enables high-performance data handling and scalability, with support for multiple virtual circuits (PVCs/PVPs).
Offers modular card-based expansion with support for redundant power supplies and uplinks, ensuring high availability and service continuity.
Equipped with STM-1/STM-4 (OC-3/OC-12) optical uplinks and E1/T1 interfaces, as well as optional Ethernet uplinks for integration with both legacy and modern networks.
Supports POTS and ISDN splitters for combined voice and broadband delivery over the same copper pair, simplifying infrastructure requirements.
Manageable via SNMP, CLI, or Alcatel OSS platforms like the 5523 ADSL Workstation, with support for remote diagnostics, provisioning, and performance monitoring.
Designed for telecom-grade environments with NEBS and ETSI compliance, capable of operating in a range of central office and remote cabinet deployments.
Built-in capabilities for loop testing and DSL line performance diagnostics reduce truck rolls and improve maintenance efficiency.
Designed to support evolving service demands and migration paths, including potential transition to IP-based infrastructure via uplink or platform upgrades.
