Ericsson ROF1375306/3 ELU 25/3 8-port extension line unit for MD110 PBX systems.

The Ericsson ROF1375306/3 is an ELU 25/3 Extension Line Unit providing 8 analogue extension ports. This board enables connection of analogue telephones and devices to Ericsson MD110 and BusinessPhone PBX systems, serving as a critical interface between the switching system and end-user analogue terminals.

The ELU 25/3 is designed for deployment within Ericsson MD110 private branch exchange systems, one of the most widely deployed enterprise PBX platforms globally. It supports standard analogue extensions, making it suitable for connecting traditional desk phones, fax machines, and other analogue endpoints within corporate telephony environments.

This is a legacy product from the Ericsson MD110 platform, which has been discontinued following the sale of Ericsson’s enterprise business to Aastra (now Mitel). However, substantial installed bases of MD110 systems remain operational worldwide, creating ongoing demand for replacement and expansion cards.
