Ericsson ROF 137 5397/1 (R4A) MD110 Telecom System Card / Module Image 1

Ericsson ICU2 interface and control unit card (ROF 137 5397/1, R4A) for the Ericsson MD110 digital PABX.

The Ericsson ROF 137 5397/1 (R4A) is an ICU2 (Interface and Control Unit) card for the Ericsson MD110 digital PABX. The exact part number, suffix and revision match published listings for this board, confirming it as the ICU2 variant within the ROF 137 5397 family.

The ICU2 sits within the MD110’s LIM (Line Interface Module) architecture, providing interface and control functions that support the other cards in the magazine. As with the rest of the MD110 card range, it is a field-replaceable plug-in unit designed to be swapped against a matching part number and revision on an existing 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.
