About This Part
The Alcatel 3AL78849AA is a dedicated interface module engineered for seamless integration within the Alcatel 1660 SM (Synchronous Multiplexer) platform. This critical component functions as a high-protection (HPROT) electrical interface, designed to reliably handle Plesiochronous Digital Hierarchy (PDH) traffic. Specifically, the Part Number 3AL78849AA provides three independent 34 Mbit/s (E3) or 45 Mbit/s (DS3) interfaces, ensuring robust and redundant connectivity for vital telecommunications services. Its design emphasizes high availability and fault tolerance, characteristic of carrier-grade equipment, making it indispensable for maintaining service integrity in demanding network environments. The module's primary role is to aggregate and transport these specific data rates over a Synchronous Digital Hierarchy (SDH) or Synchronous Optical Network (SONET) backbone, bridging legacy PDH infrastructure with modern optical transport networks. This Alcatel module is typically deployed within the core or access layers of telecommunications networks, where it supports the transport of traditional voice, data, and video services. It is essential for telecom operators, internet service providers, and large enterprises that maintain extensive legacy infrastructure or require specific PDH connectivity for specialized applications. The 3AL78849AA is installed directly into the Alcatel 1660 SM chassis, enabling operators to extend the lifespan and functionality of their existing SDH/SONET platforms. It solves the challenge of integrating diverse network elements and services, providing a reliable pathway for traffic that may not yet be migrated to packet-based technologies. Its high-protection feature ensures minimal service disruption, making it a cornerstone for mission-critical communications. Revo Distribution Limited specializes in providing B2B clients with cost-effective, high-quality used and refurbished telecom and data centre equipment, including the Alcatel 3AL78849AA.
