OPTIMUS announces the operational success of its OPTIMAX3 platform across Adif’s infrastructure network.

This deployment represents one of the most significant engineering milestones in the Spanish railway sector, enabling the coordination of public address and critical communications across hundreds of stations, from major terminals to small halts, under a single efficient hierarchical structure.

The challenge of centralized management

Adif manages a highly diverse network of stations that requires local autonomy without sacrificing centralized supervision. OPTIMUS’ solution organizes this complexity from the Stations Control Center (CNE) in Valdebebas, Madrid. The OPTIMAX3 architecture enables a three-level cascading management structure: global control in Valdebebas, supervision across six territorial subcenters, and individual operation at each station.

This structure ensures that even in the event of a loss of global connectivity, each node maintains its local functionality, guaranteeing service continuity and passenger safety at all times. From the OPTIMUS Project Management Department in Madrid, the importance of this architecture is emphasized:

What we were looking for in project management was a solid and resilient solution. With OPTIMAX3, each station has its own intelligence; the robustness of the system gives us peace of mind that, whatever happens in the global network, local autonomy is safeguarded and the station will never be left unprotected.

UMX-03 Matrix: critical communications management and IP redundancy

At the core of the platform is the UMX-03 digital matrix. With redundant IP connectivity, it simultaneously manages four incoming and outgoing IP audio channels while maintaining a 16-channel internal bus for local processing. Its design includes direct integration with fire alarm systems through three supervised input contacts and safety fault relay outputs. The 32 GB internal memory ensures the availability of critical messages even during network failures, while its CAN bus allows the connection of microphone paging stations and noise sensors with continuous supervision.

Flexibility in distribution and integrated power

• For installations where existing analog amplifiers must be retained or audio needs to be distributed to remote points, the IF-822ETH and IF-804ETH interfaces transform conventional systems into IP nodes with 16 GB of internal storage.
• When the project requires distributed power, the IF-8P4ETH unit integrates IP control with up to four Class D amplifiers (from 60 to 460 W). Its hot swapping capability allows maintenance operations without interrupting railway service, an essential feature in high-availability infrastructures.

Beyond the railway sector

OPTIMAX3 is an architecture designed to adapt to the most demanding workflows. Although the Adif project is one of its most emblematic use cases, the versatility of the platform makes it ideal for industrial complexes, port infrastructures or distributed corporate campuses that require coordinated and scalable communications, among many other applications.

Ready for the future

The OPTIMAX3 platform not only responds to current transport needs but has also been designed to evolve with the most demanding standards in the market. From the OPTIMUS Innovation Department, the importance of regulatory compliance in the system’s DNA is highlighted:

Our vision in R&D has always been to anticipate the challenges of critical infrastructure. OPTIMAX3 was conceived from the outset to align with the EN 54 standard, already integrating the necessary supervision, redundancy and emergency management functions. Everything is ready for compliance with this standard to be the next natural step in the evolution of a system that is already a benchmark in railway safety and designed for a long, scalable lifecycle.

With this deployment, OPTIMUS reaffirms its commitment to operational excellence and its ability to deliver tailored solutions for the most critical and complex environments in the global market.
