ROF1375397/1 Ericsson Ericsson AXE System Module

The Ericsson ROF1375397/1 is an ICU 2 (Interface Control Unit 2), a system module designed for use within Ericsson’s AXE digital telephone exchange platform. The ICU 2 provides interface control and signal processing functions, managing communication between different subsystems within the exchange architecture.

This module is deployed in Ericsson AXE-based fixed-line and mobile switching centres, where it handles interface coordination and data flow management between the exchange’s central processor and peripheral equipment. The ICU is an essential component in maintaining reliable call processing and system integrity within large-scale telecommunications networks.

The AXE platform is a legacy system that has been widely deployed globally by telecommunications operators since the 1970s. While now considered end-of-life, many AXE installations remain operational, particularly in regions where network modernisation is ongoing. Replacement ICU 2 units are sought for maintenance and life extension of existing infrastructure.
