Product Overview
The Alcatel-Lucent 3AL78849AA, known as the HPROT module, is a protection and redundancy unit used in Alcatel-Lucent ISAM access platforms. It provides hardware protection switching for line cards and service modules inside the chassis. Because the module monitors card status and handles automatic failover, it helps maintain stable service delivery in broadband networks. In addition, it integrates directly into the ISAM shelf architecture. As a result, the HPROT module supports continuous operation in demanding access environments.

Technical Specification Highlights
The 3AL78849AA HPROT module is engineered to provide redundancy functions for ISAM line cards. It supervises the operational state of protected modules and triggers switchover when faults occur. Because the module communicates with the control plane, it participates in system-wide fault management and alarm processing. It fits into the designated protection slot of the ISAM shelf and supports high-density access environments. The hardware is designed for low power consumption and offers stable operation under telecom-class temperature ranges. Furthermore, the hot-plug capability allows technicians to replace the module without service interruption. The protection logic supports both single and paired configurations depending on the deployment model.
Usage & Application
This module is used in Alcatel-Lucent ISAM broadband access nodes deployed in central offices, distribution sites and street cabinets. Because it enables redundancy for service cards, it is essential in networks that deliver DSL, VDSL, voice, and business access services. It fits scenarios where continuous broadband availability is required. Moreover, the module supports maintenance procedures where cards can be replaced or upgraded while traffic remains active. As a result, it enhances system resilience in large-scale access infrastructures.
Why Choose this Product
Choose the Alcatel-Lucent 3AL78849AA HPROT module if you need a reliable hardware protection unit for ISAM platforms. It offers stable redundancy switching, integrates seamlessly into the chassis and supports long-term continuous operation.
