ROF1375339/11 R9H Ericsson Ericsson MD110 PBX Expansion Card

The Ericsson ROF1375339/11 R9H is an ELU 29 Extension Line Unit providing 16 analogue extension ports for Ericsson MD110 and BusinessPhone PBX systems. This board enables connection of standard analogue telephones and devices to the switching system, handling signalling and voice traffic for each connected line.

The ELU 29 is designed for deployment within Ericsson’s enterprise telephony platforms, where analogue extension capacity is required alongside digital and IP endpoints. It slots into the MD110 magazine infrastructure, providing a cost-effective method of expanding analogue line density within existing installations.

This is a legacy product from the Ericsson MD110 family, which has been widely deployed in enterprise environments globally. While the platform is now discontinued, many installations remain in active service, creating ongoing demand for replacement and expansion boards. The R9H revision indicates a later hardware iteration with accumulated improvements.
