Alcatel‑Lucent 3AL00114AB Universal Interface Module

The Alcatel‑Lucent 3AL00114AB is a versatile universal interface module designed for use across multiple Alcatel‑Lucent chassis and shelf systems. This board functions as a connectivity bridge, providing power distribution, signal conditioning, and mechanical support for various daughter cards and plug‑in modules within the host platform.

Product Overview

Part number 3AL00114AB identifies a general‑purpose interface board that can be deployed in control, switching, or access shelves. Its primary role is to bring external connections – such as power feeds, alarms, and communication buses – to the backplane, while also offering filtering and protection against electrical disturbances. The board is often used in conjunction with main processing units to expand I/O capabilities.

Although the part listing may include a "NO BOX" notation, that is purely a packaging indicator and does not affect the product’s functionality or specifications. The module itself is a fully featured, ready‑to‑install circuit card.

Deployment and Integration

This module is commonly used as a front‑end interface between the backplane and external cabling panels. In many installations, it aggregates power from multiple redundant feeds and distributes it to line cards, while also providing a bus for system management signals like alarms and fan control.

The 3AL00114AB can also serve as a termination board for unused backplane slots, ensuring proper impedance matching and signal termination to prevent reflections. Its robust design handles the high current demands of densely populated shelves.

Maintenance and Reliability

Because the module has no moving parts and uses derated components, it offers exceptional reliability. MTBF is estimated at over 300,000 hours. The board is fully testable via boundary‑scan (JTAG) and includes self‑power‑up diagnostics that report any faults through status LEDs.

Replacement, if necessary, follows standard ESD procedures. The module is keyed to prevent incorrect insertion, and all connectors are gold‑plated for corrosion resistance.

Compliance

This module meets the requirements of RoHS, REACH, and NEBS level 3 for temperature and fire resistance. It is also designed to comply with UL 60950‑1 for safety.

Conclusion

The Alcatel‑Lucent 3AL00114AB universal interface module is a reliable and flexible building block for various telecommunications chassis. Its ability to handle power distribution, signal conditioning, and backplane connectivity makes it a valuable component for maintaining system integrity and simplifying infrastructure design.
