ROF1314413/3 Ericsson AXE System Module

The Ericsson ROF1314413/3 is a Line Switch Unit, revision 3 (LSU/3), designed for use within Ericsson AXE digital telephone exchange systems. This module serves as a critical switching component within the group switch subsystem, handling the routing and connection of subscriber lines and trunk circuits.

The LSU/3 operates within the AXE platform’s modular architecture, which has been widely deployed by telecommunications operators globally for public switched telephone networks (PSTN) and mobile switching centres. The line switch unit is responsible for establishing and maintaining circuit-switched connections across the exchange fabric.

As part of Ericsson’s legacy AXE infrastructure, the LSU/3 supports operators maintaining established exchange installations. While newer packet-based solutions have superseded AXE in many deployments, significant AXE infrastructure remains operational worldwide, creating ongoing demand for replacement modules and spare parts.
