ROA1195132/1 Ericsson AXE System Module

The Ericsson ROA1195132/1 is a PUB 6 backplane, designated as BP 250, designed for use within Ericsson’s AXE digital switching platform. As a backplane unit, it provides the physical interconnection framework that allows processor and peripheral boards to communicate within the exchange system.

This backplane is an integral component of the AXE switching architecture, facilitating signal routing and power distribution between installed magazine units. The BP 250 designation indicates its specific configuration within the PUB (Processor Unit Bus) subsystem hierarchy.

The AXE platform represents Ericsson’s legacy digital switching technology that was widely deployed by telecommunications operators globally. While this is discontinued infrastructure, many networks continue to operate AXE exchanges, creating ongoing demand for replacement backplanes and maintenance spares.
