ROF1375406/11 Ericsson Ericsson AXE System Module

The Ericsson ROF1375406/11 is a TLU/80 (Timing and Line Unit) module designed for use within Ericsson’s AXE digital switching platform. This unit provides essential timing synchronisation and line interface functionality, ensuring accurate clock distribution and signal integrity across the switching system.

The TLU/80 is deployed within Ericsson AXE exchanges, which have historically served as the backbone for fixed-line telecommunications networks worldwide. These systems handle call processing, routing and network management for public switched telephone networks (PSTN) and integrated services digital networks (ISDN).

As part of the legacy AXE platform, this module is suited for operators maintaining existing Ericsson infrastructure. The AXE series has been widely deployed by telecommunications carriers globally, and replacement units remain in demand for system maintenance and life-extension projects.
