ROF1375064/6 Ericsson MD110 PBX Expansion Card

The Ericsson ROF1375064/6 is an ELU 34/6 Extension Line Unit designed to provide analogue extension line interfaces within Ericsson telecommunications systems. This board enables the connection of analogue telephones and devices to the digital switching infrastructure, handling the necessary conversion between analogue signals and the digital backplane.

The ELU 34/6 is a component of the Ericsson MD110 PBX platform, a widely deployed enterprise communication system. It provides multiple analogue extension ports, allowing organisations to support traditional telephone handsets, fax machines, and other analogue terminal equipment within their private branch exchange environment.

The MD110 platform, while a proven and reliable system that served many enterprise deployments globally, is now considered legacy infrastructure. Organisations maintaining existing MD110 installations may require replacement boards to sustain operations or support gradual migration strategies.
