Ericsson ROF 137 5334/3 (R1B) MD110 Telecom System Card / Module Image 1

Ericsson ELU28 extension board (ROF 137 5334/3, R1B) for the Ericsson MD110 digital PABX.

The Ericsson ROF 137 5334/3 (R1B) is an ELU28 extension board for the Ericsson MD110 digital PABX. The exact ROF 137 5334/3 part number is a documented ELU28 card, and this listing is for the R1B revision within that family.

ELU boards handle extension line interfacing within the MD110’s LIM architecture, connecting subscriber terminal equipment into the switch. The ELU28 variant has shipped across a range of revisions over the platform’s life, and this card is intended as a direct, field-replaceable swap against a matching part number and revision on an existing MD110 system.

It’s a good match for organisations maintaining an existing Ericsson MD110 estate who need matching hardware for expansion, redundancy or like-for-like replacement. Tech-Star (UK-based, shipped worldwide) checks every module before it ships. Get in touch to confirm compatibility with your MD110 configuration.
