TSR491406/500 Ericsson Ericsson AXE Telecom Module

The Ericsson TSR491406/500 is an MX cable assembly designed to interconnect the LSU/16 (Line Switch Unit) and LPU5/13 (Line Protection Unit) within Ericsson telecommunications switching infrastructure. This cable provides the essential signal and data pathways between these two functional units in the switching system architecture.

This cable is used within Ericsson’s AXE digital switching platform, specifically for connecting line-side equipment within the exchange. The LSU/16 handles subscriber line connections whilst the LPU5/13 provides protection switching capabilities, and this MX cable ensures reliable communication between the two modules.

The TSR491406/500 is a legacy component from Ericsson’s established AXE switching platform. Whilst this technology has been largely superseded by next-generation systems, many operators continue to maintain and extend the life of their existing AXE installations, creating ongoing demand for spare parts and cables such as this.
