The Ericsson ROF 137 5216/4 (R4C) is an ELU11 extension unit board for the Ericsson MD110 digital PABX. The ROF 137 5216 part family is a documented ELU11 board used in MD110 installations, and this listing covers the /4 suffix and R4C revision build within that family.
ELU boards in the MD110 range provide extension line interfacing, connecting subscriber lines and terminal equipment into the switch’s LIM architecture. Different suffixes and revisions within the same ROF part number typically reflect production and firmware updates to the same underlying board function, and this card is intended as a direct, field-replaceable swap for a matching part number and revision.
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.
