Ericsson ROF1575113/1 BTU-E(4) 4-port E&M tie line interface board for MD110 PBX.

The Ericsson ROF1575113/1 is a BTU-E(4) board providing four E&M (Earth & Magneto) tie line interfaces. This card enables trunk connections between PBX systems or to external switching equipment using analogue E&M signalling, a standard method for interconnecting telephone switches.

This board is designed for use within the Ericsson MD110 business communications platform, specifically the R3D software release. It allows the MD110 to establish tie line connections to other PBXs, carrier equipment, or legacy switching infrastructure requiring E&M signalling protocols.

The MD110 is a legacy PBX system that was widely deployed in enterprise environments. While no longer in active production, many MD110 installations remain operational, and spare parts such as this BTU-E(4) board are essential for maintaining these systems.
