The Ericsson ROF131708/2 is the REU (Ring generator Unit) for the Ericsson MD110 / MX-ONE digital PBX. It is a DC/AC converter that generates the AC ringing signal used to alert connected telephones, typically fitted one per LIM (Line Interface Module) within the system. The REU takes the exchange’s central battery DC supply and converts it into the AC voltage required for ringing, feeding the line boards that serve the extensions.
This is a legacy component from the MD110 family, a modular digital PBX widely deployed in enterprise and multi-site environments and later supported under the Aastra and Mitel MX-ONE portfolios. It remains in demand for organisations maintaining existing MD110 installations or holding spares for installed line equipment.
