ROF1575118/2 Ericsson Ericsson AXE System Module

The Ericsson ROF1575118/2 is a CPU-D2 central processing unit module designed for use within Ericsson’s AXE digital switching platform. This processor board provides core computational functions essential for call processing, signalling handling, and system control operations within the exchange infrastructure.

The CPU-D2 module is deployed within Ericsson AXE telephone exchanges, which have served as the backbone of fixed-line and mobile network switching across telecommunications operators worldwide. These processor units are critical components in maintaining the operational integrity of switching systems handling voice and data traffic.

The AXE platform is a legacy system that has been widely deployed since the 1970s and remains operational in many networks globally. While Ericsson has transitioned to newer platforms, the AXE system continues to require maintenance and spare parts support for existing installations.
