C111574 Nokia Nokia BTS Base Station Module

The Nokia C111574 is a TSS3-A (Transmission Subsystem 3-A) module designed for Nokia mobile network base station infrastructure. This hardware component handles transmission functions within the base station system, managing data and signalling pathways between radio equipment and the core network.

The TSS3-A module is deployed within Nokia base station configurations, typically serving 2G, 3G or early LTE network architectures. It provides essential transmission processing capabilities required for backhaul connectivity and inter-element communication within the radio access network.

This is a legacy Nokia module from earlier generations of mobile network infrastructure. While superseded by newer transmission solutions in current deployments, it remains relevant for operators maintaining established Nokia networks or requiring spare parts for existing installations.
