TSR491409/100 Ericsson Ericsson AXE Telecom Module

The Ericsson TSR491409/100 is an MX cable assembly designed to interconnect the Line Switch Unit Extended (LSU-E) with the Digital Service Unit (DSU) within Ericsson telecommunications systems. This cable provides the critical physical connection required for signal transmission between these two functional units.

This cable is used in Ericsson AXE and related digital switching platforms, where the LSU-E handles line-side functions and the DSU manages digital service interfaces. Proper cabling between these units is essential for maintaining signal integrity and system reliability in exchange environments.

The TSR491409/100 is a legacy component associated with Ericsson’s traditional circuit-switched infrastructure. While these platforms have largely been superseded by modern packet-based systems, they remain operational in various telecommunications networks worldwide, creating ongoing demand for replacement and maintenance parts.
