ROF1575025/12 Ericsson Ericsson MD110 PBX Expansion Card

The Ericsson ROF1575025/12 is an ELU-A (Extension Line Unit – Analogue) board designed for the Ericsson MD110 private branch exchange system. This unit provides connectivity for analogue extension devices, enabling the connection of standard analogue telephones, fax machines, and modems to the MD110 switching platform. The “(10)” designation indicates this variant supports 10 analogue extension ports.

The ELU-A board is a core component within MD110 and BusinessPhone systems, allowing organisations to maintain analogue device connectivity within their enterprise telephony infrastructure. It slots into the MD110 magazine chassis and interfaces with the system’s switching fabric to provide dial tone and call handling for connected analogue endpoints.

The Ericsson MD110 is a legacy PBX platform that was widely deployed across enterprise environments globally. While the system has been discontinued and superseded by more modern IP-based solutions, many installations remain in active service. This refurbished ELU-A board provides a cost-effective option for maintaining and expanding existing MD110 deployments.
