Ericsson TSR491411/1850 MX Cable for LSU(E) to DSU(n) connection.

The Ericsson TSR491411/1850 is an MX interconnect cable designed to connect a Line Switch Unit Extended (LSU-E) to a Device Switch Unit (DSU-n) within Ericsson telecommunications infrastructure. This cable facilitates internal system communication between switching units, ensuring reliable signal transmission across the equipment backplane or rack.

This cable is used within Ericsson’s MD110 or BusinessPhone PBX platforms, where modular switching architecture requires dedicated cabling between line-side and device-side units. The LSU handles subscriber line interfaces whilst the DSU manages device connections, making this cable essential for proper system configuration and expansion.

The TSR491411/1850 is a legacy component associated with Ericsson’s traditional circuit-switched PBX systems. These platforms have been largely superseded by IP-based solutions, though many installations remain in service requiring ongoing maintenance and spare parts support.
