ROF1375314/2 Ericsson Ericsson AXE System Module

The Ericsson ROF1375314/2 is a Time Switch Unit (TSU) designed for use in Ericsson AXE digital telephone exchange systems. The TSU is a critical component responsible for time-division multiplexing and switching operations within the exchange, enabling the routing of voice and data traffic across the telecommunications network.

This module forms part of the Group Switch Subsystem (GSS) in AXE exchanges, handling the high-capacity switching fabric that connects multiple subscriber stages and trunk circuits. The TSU works in conjunction with other switching modules to provide non-blocking connectivity for thousands of simultaneous calls.

The AXE platform is a legacy digital switching system that was widely deployed by telecommunications operators worldwide. While largely superseded by modern softswitch and IMS-based architectures, AXE systems remain operational in certain networks, creating ongoing demand for replacement modules to maintain service continuity.
