TSR9010491/850 Ericsson Ericsson AXE Telecom Module

The Ericsson TSR9010491/850 is an LSU-DSU1 SLIM cable designed for interconnecting Line Switch Units (LSU) and Digital Service Units (DSU) within Ericsson telecommunications infrastructure. This specialised interconnect cable facilitates data and signalling transmission between critical system components in carrier-grade network deployments.

This cable is typically deployed within Ericsson AXE or similar digital switching platforms, where reliable connections between line-side and digital service modules are essential for maintaining call processing and network services. The SLIM designation indicates a compact or reduced-profile cable design suited for high-density installations.

As legacy Ericsson switching infrastructure, this component supports operators maintaining existing AXE-based networks or similar platforms. While these systems are being phased out in favour of newer IP-based architectures, many installations remain operational and require replacement parts for ongoing maintenance.
