Ericsson ROF 131 4309/2 (R3B) MD110 Telecom System Card / Module Image 1

Ericsson TRU3 plug-in circuit board (ROF 131 4309/2, R3B) for the Ericsson MD110 digital PABX switch.

The Ericsson ROF 131 4309/2 (R3B) is a TRU3 plug-in circuit board for the Ericsson MD110 digital PABX switch. It carries the Ericsson-standard ROF part number format used across the MD110 card range, with the /2 suffix and R3B revision marking identifying this specific board build.

The TRU3 board is one of the family of function-specific cards that slot into an MD110 magazine alongside units such as the DSU, LSU and LPU boards, each handling a defined role within the switch’s modular architecture. As with other MD110 line cards, it is a field-replaceable unit intended for direct swap-in against a matching part number and revision on an existing installation.

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.
