Ericsson ROF1375349/2 MD110 / MX-ONE Telecom System Card / Module

The Ericsson ROF1375349/2 is a TLU79 (Trunk Line Unit) board used within Ericsson’s MD110 and MX-ONE communication systems. It sits in the same TLU79 family as the confirmed ROF1375349/1 8-port trunk line card already stocked by Tech-Star, and MD110/MX-ONE trunk line units of this type provide the physical interface between the PBX group switch and external trunk circuits, carrying voice and signalling traffic between the exchange and the wider telephone network. MD110 remains widely deployed across enterprise and carrier customer sites worldwide, including many installations that have since migrated to the software-compatible MX-ONE platform while retaining the original MD110 hardware magazines, so genuine TLU boards such as this one continue to be in demand as maintenance spares. As with other boards in the ROF1375349 index family, hardware and firmware revision compatibility with the host system’s software load should be confirmed before fitting. Genuine TLU79 boards are recovered from decommissioned or upgraded exchanges and tested before resale, since new manufacture of this legacy board type has ceased. Tech-Star (UK-based, shipped worldwide) stocks TLU79 trunk line cards including the ROF1375349/2 for operators and integrators maintaining MD110 and MX-ONE estates.
