About This Part
The Alcatel 3HE02781AA, also known by its internal designation A32-CHDS1V2, is a high-density channelized DS1/E1 interface module designed for Alcatel-Lucent's carrier-grade service router and switch platforms, such as the 7750 Service Router (SR) or 7450 Ethernet Service Switch (ESS). This modular line card provides robust connectivity for legacy TDM services, enabling the aggregation and termination of up to 32 individual DS1 (T1) or E1 circuits. Each port supports various modes including clear channel, fractional T1/E1, and channelized operations, facilitating the transport of voice, data, and signaling traffic over a packet-based infrastructure. The card is engineered to deliver reliable performance for critical applications, supporting protocols like PPP, Frame Relay, and HDLC, essential for integrating traditional access networks with modern IP/MPLS backbones. Its primary function is to bridge the gap between legacy TDM equipment and next-generation packet networks, offering high port density for efficient space and power utilization within the network chassis. The Part Number 3HE02781AA is crucial for operators maintaining or expanding services that rely on these established circuit-switched technologies. The Alcatel 3HE02781AA module is typically deployed in the core or aggregation layers of telecommunications networks, specifically within Alcatel-Lucent's modular chassis systems. It serves as a vital component for service providers, mobile network operators, and large enterprises that need to support a diverse range of legacy services while transitioning to or operating within an IP/MPLS environment. Common use cases include interconnecting with Public Switched Telephone Networks (PSTN) for voice services, providing traditional data access for business customers via T1/E1 lines, and supporting older generation cellular backhaul infrastructure. This card solves the challenge of integrating existing TDM-based customer premises equipment (CPE) or central office (CO) switches with modern packet-switched networks, eliminating the need for costly and disruptive full-scale infrastructure overhauls. It enables operators to continue offering revenue-generating legacy services, extend the operational life of existing TDM equipment, and provide a seamless migration path for customers. By aggregating multiple T1/E1 circuits onto a single, high-capacity packet-based platform, it optimizes network resources and reduces operational complexity.
