Ericsson DSU distributed switch unit board (ROF 131 4414/4, R7B) for the Ericsson MD110 digital PABX.

The Ericsson ROF 131 4414/4 (R7B) is a DSU (Distributed Switch Unit) board for the Ericsson MD110 digital PABX. The DSU is one of the core switching cards in the MD110’s Line Interface Module (LIM) architecture, and this part carries the /4 variant and R7B revision marking.

The MD110 is a modular, expandable digital switch whose job is to carry PCM voice, data and control signals between LIMs; the DSU board performs the distributed switching function that keeps that traffic moving across the magazine. The DSU family has shipped in many sibling variants and revisions across the life of the MD110 platform, and this listing is for the specific ROF 131 4414/4 R7B build.

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.
