ROF1375412/4 Ericsson Ericsson MD110 PBX Expansion Card

The Ericsson ROF1375412/4 is an ELU31/4 interface card providing connectivity for up to eight DECT base stations within Ericsson MD110 and BusinessPhone PBX systems. This board enables wireless DECT telephony by linking base station units to the central telephone exchange, supporting cordless handset communication across enterprise environments.

The ELU31 series cards are essential components for deploying DECT wireless coverage in MD110 installations. Each port on the card connects to an individual DECT base station, allowing flexible coverage expansion across office buildings, warehouses, and campus environments where mobile telephony is required.

This is a legacy product from the Ericsson MD110 platform, which has been discontinued following the acquisition by Mitel. However, the ELU31/4 remains in demand for maintaining and expanding existing MD110 DECT infrastructure where replacement of the entire system is not practical.
