ROF1314413/5 Ericsson Ericsson AXE System Module

The Ericsson ROF1314413/5 is a Line Switch Unit, designated LSU/5, designed for use within Ericsson’s AXE digital telephone exchange platform. This unit forms part of the switching subsystem, handling the connection and routing of subscriber lines within the exchange architecture.

The LSU/5 operates within the Group Switch Subsystem (GSS) of AXE exchanges, facilitating the switching matrix functions that connect subscriber stages to trunk and junction circuits. It is an essential component for maintaining call routing capacity and line handling within large-scale telecommunications networks.

This is a legacy product associated with Ericsson’s AXE family of exchanges, which has been widely deployed by fixed-line operators globally since the 1970s. While the platform has been superseded by newer packet-based technologies, AXE systems remain operational in many networks, creating ongoing demand for replacement and maintenance parts.
