ROF1575116/2 Ericsson Ericsson MD110 PBX Expansion Card

The Ericsson ROF1575116/2 is an ELU-D (8) Extension Line Unit designed to provide digital extension interfaces within Ericsson MD110 business communication systems. This board enables the connection of eight digital telephone terminals to the PBX, delivering voice and data services to end-user devices across the enterprise.

The ELU-D module is deployed within the MD110 switching platform, one of Ericsson’s most widely installed enterprise PBX systems. It slots into the system’s Line Interface Module (LIM) magazine and provides the necessary circuitry for digital set connectivity, supporting features such as display messaging, function keys, and integrated data ports on compatible handsets.

The MD110 platform is a legacy system that has been widely deployed across corporate, government, and institutional environments globally. While the platform has been discontinued by Ericsson, significant installed bases remain operational, creating ongoing demand for replacement and expansion boards such as the ELU-D. Refurbished units offer a cost-effective solution for maintaining and extending these systems.
