TSR491406/170 Ericsson Ericsson AXE Telecom Module

The Ericsson TSR491406/170 is an MX interconnect cable designed to provide connectivity between the LSU-E (Line Switch Unit – Extended) and the DSU/14 (Distribution Switch Unit) within Ericsson telecommunications switching infrastructure. This cable facilitates the essential signal and data pathways between these two critical system components.

This cable is used within Ericsson AXE digital switching platforms, where the LSU-E handles subscriber line connections and the DSU manages traffic distribution across the exchange. The MX cable type indicates it is part of the internal cabling system used for inter-module communication within the exchange equipment.

The TSR491406/170 is a legacy component associated with Ericsson’s traditional circuit-switched telephony infrastructure. While these platforms have largely been superseded by IP-based solutions, they remain in service in various telecommunications networks worldwide, creating ongoing demand for maintenance spares and replacement cables.
