ROF1575114/1 Ericsson MD110 PBX Expansion Card

The Ericsson ROF1575114/1 is an ELU-A (16) Extension Line Unit designed for use within Ericsson MD110 and BusinessPhone PBX systems. This board provides 16 analogue extension line interfaces, enabling connection of standard analogue telephones, fax machines, and modems to the telephone exchange.

The ELU-A module is a core component of Ericsson’s enterprise telephony infrastructure, providing reliable analogue connectivity within larger digital switching environments. It is typically installed in the Line Interface Module (LIM) magazine of MD110 systems to expand user capacity.

The MD110 platform is a legacy enterprise PBX system that was widely deployed across corporate and institutional environments. Whilst discontinued, many installations remain in active service, creating ongoing demand for replacement and expansion hardware.
