TSR9010499/20 Ericsson Ericsson TSR Series Telecom Module

The Ericsson TSR9010499/20 is a stack-to-stack alarm cable designed to interconnect alarm signalling between stacked Ericsson telecommunications equipment. This cable facilitates the transfer of alarm and fault notification signals between vertically stacked units, enabling centralised monitoring and management of multiple chassis within a single equipment stack.

This alarm cable is typically deployed within Ericsson mobile network infrastructure, including base station sites and transmission equipment installations. It ensures that alarm conditions from individual units within a stack are properly propagated to network management systems, maintaining operational visibility across multi-chassis configurations.

As part of Ericsson’s established telecommunications portfolio, this cable supports legacy and current-generation equipment requiring stack interconnection for alarm consolidation. It is an essential component for maintaining proper fault management in stacked deployment scenarios.
