Ericsson ROA1173008/2 AXE Telecom System Card / Module

The Ericsson ROA1173008/2 is an SXU-A (Switch Extension Unit Type A), a hardware module designed for use within Ericsson’s AXE family of digital telephone exchange systems. The SXU-A serves as a switching extension component that expands the capacity and connectivity of the central group switch within AXE-based network infrastructure.

This unit is deployed in telecommunications carrier environments where Ericsson AXE exchanges handle voice switching and signalling. The SXU-A integrates into the group switch subsystem, enabling the exchange to manage additional traffic paths and subscriber connections across the network.

The AXE platform is a legacy system that has been widely deployed by telecommunications operators globally since the 1970s. While many networks have transitioned to newer architectures, AXE exchanges remain operational in various regions, creating ongoing demand for replacement and spare components such as the SXU-A.
