Ericsson ROF1375406/1 MD110 / MX-ONE Telecom System Card / Module

The Ericsson ROF1375406/1 is a TLU80 digital trunk line card used within Ericsson’s MD110 and MX-ONE communication systems. It is confirmed as part of the TLU80 family via the sibling ROF1375406/11 board already stocked by Tech-Star, also documented as a TLU80 digital trunk line card for MD110 and MX-ONE. Trunk line units of this type provide the physical interface between the PBX group switch and external digital 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 ROF1375406 index family, hardware and firmware revision compatibility with the host system’s software load should be confirmed before fitting. Genuine TLU80 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 TLU80 digital trunk line cards including the ROF1375406/1 for operators and integrators maintaining MD110 and MX-ONE estates.
