ROF1314602/3 Ericsson Ericsson AXE Telecom System Card

The Ericsson ROF1314602/3 is an LPU5/3 (Line Protection Unit), a circuit board designed to provide overvoltage and overcurrent protection for subscriber lines within Ericsson AXE digital telephone exchange systems. This unit safeguards sensitive exchange equipment from electrical surges, lightning strikes and other transient events that could damage line interface circuits.

The LPU5/3 is deployed within the subscriber stage of AXE exchanges, protecting the connection between external copper subscriber lines and the internal switching fabric. It forms part of the line interface module assembly, ensuring reliable protection across multiple subscriber circuits simultaneously.

This is a legacy component from the Ericsson AXE platform, which served as a cornerstone of fixed-line telecommunications infrastructure for network operators worldwide. Whilst the AXE platform has been superseded by newer generations of switching technology, many exchanges remain operational and require spare parts for ongoing maintenance.
