Ericsson TSR491406/120 MX Cable for LSU-E to DSU/14 connection.

The Ericsson TSR491406/120 is an MX cable designed to provide connectivity between the LSU-E (Line Switch Unit – Extended) and the DSU/14 (Digital Subscriber Unit). This interconnect cable facilitates signal transmission within Ericsson mobile network infrastructure, ensuring reliable communication between switching and subscriber interface equipment.

This cable is used within Ericsson’s mobile switching and base station subsystem environments, where precise interconnection between line switching modules and digital subscriber units is essential for network operation. The LSU-E and DSU components form part of Ericsson’s traditional GSM and mobile core network architecture.
