ROF1375339/1 Ericsson Ericsson MD110 PBX Expansion Card

The Ericsson ROF1375339/1 is an ELU 29 (Extension Line Unit 29), a subscriber line interface board designed for the Ericsson MD110 private branch exchange system. This unit provides analogue extension line ports, enabling the connection of standard analogue telephones and devices to the MD110 switching platform.

The ELU 29 is deployed within MD110 cabinet configurations to expand the system’s capacity for analogue extensions. It serves enterprise telephony environments where a mix of digital and analogue endpoints is required, supporting traditional desk phones, fax machines, and other analogue terminal equipment.

As part of the legacy Ericsson MD110 platform, this unit is associated with systems that have been widely deployed but are now considered end-of-life. The MD110 remains operational in many installations, and replacement boards such as the ELU 29 are sought for maintenance and capacity expansion of existing infrastructure.
