Ericsson ROF1375412/1 ELU 31 Extension Line Unit for MD110 PBX systems.

The Ericsson ROF1375412/1 is an ELU 31 (Extension Line Unit 31) board designed for use in Ericsson MD110 business communication systems. This line unit provides analogue extension interfaces, enabling the connection of standard analogue telephones and devices to the MD110 PBX platform.

The ELU 31 is deployed within MD110 cabinet configurations to expand the system’s capacity for analogue subscriber lines. It serves as a key interface board for organisations requiring traditional analogue endpoints alongside digital telephony infrastructure.

The Ericsson MD110 is a legacy PBX platform that was widely deployed in enterprise and public sector environments. While the system has been discontinued and superseded by newer Ericsson and Aastra platforms, many installations remain operational and require replacement boards and spare parts for ongoing maintenance.
