Ericsson TSR491406/1850 MX cable for LSU-E to DSU/14 interconnection.

The Ericsson TSR491406/1850 is an MX interface cable designed to connect the LSU-E (Line Switch Unit – Enhanced) to the DSU/14 (Distribution Switch Unit) within Ericsson telecommunications infrastructure. This cable provides the essential physical interconnection required for signal transmission between these switching units.

This cable is used within Ericsson MD110 / MX-ONE digital switching systems, where the LSU-E handles subscriber line interfaces and the DSU manages traffic distribution across the switching network. The MX designation indicates a specific multiplexed interface standard used in these legacy platforms.

The TSR491406/1850 is a legacy component from Ericsson’s traditional fixed-line switching portfolio. While these MD110 / MX-ONE-based systems have been superseded by newer softswitch and IP-based architectures, many installations remain operational worldwide, requiring ongoing maintenance and spare parts support.
