Connected Backbone and OCC Networks

A robust, flexible and reliable interconnecting backbone for subsystems


The modern mass transit organization has vast communication needs. The ever-increasing degree of train automation, complexity of security measures, and level of passenger demands will tax your system. Multiple applications require guaranteed throughput and have precise requirements, so the interconnecting backbone network must be robust, flexible and reliable.


The Connected Backbone and OCC Network integrates advanced communication systems and data analytics to provide real-time insights into the status of transit operations. This not only aids in immediate decision-making but also in planning and forecasting for future needs. Key outcomes include improved security and surveillance capabilities, thanks to digital networks that offer enhanced monitoring and immediate response to incidents. Ultimately, these technologies contribute to making public transportation safer, more reliable, and efficient. 


Elements to consider for connected backbone and OCC networks


Areas of operations (AO) interconnections

AI (Artificial Intelligence) concept. Electronic circuit. Communication network


The backbone network bridges mission-critical functions of onboard systems, trackside/wayside devices, and in-station assets through multiple redundant networks or blended, shared-service environments.

Key benefits of connected backbone and OCC networks



Network ability offer services consistently, even during failures



Maximum amount of data able to be transmitted at a given time


Delay before a transfer of data begins following an instruction for its transfer



Ability to preserve data in the event of a failure


Automated fault resolution

Detecting and correcting potential or active faults without user interaction



Costs associated with all pieces of network design, components, implementation, and servicing

Customer service

Ability to provide rapid assistance to end-users




Our approach to connected backbone and OCC network solutions


Early planning to optimize the backbone network’s design enhances a solution’s overall performance, flexibility, scalability and cost-effectiveness. Attention paid to the network design early in the project saves time over fundamental design changes made later in the process.


Belden has the expertise to manage such complexity based on a deep knowledge of well-documented uses built specifically for rail applications. Our approach begins with a thorough analysis of the requirements, followed by designing, securing, deploying, and validating a solution that best adapts to the specific case.
