ATM operations depend on the reliable and predictable performance of voice, data, and surveillance networks to ensure safe and efficient airspace management. However, heterogeneous infrastructures, multiple vendors, and evolving technology landscapes make real-time monitoring and control increasingly complex for ANSPs. Traditional network monitoring solutions often operate in silos, limiting the ability to detect, correlate, and respond to issues that span multiple network layers and service domains. Without a unified situational awareness framework, network teams face delays in diagnosing and mitigating failures, increasing operational risks.

Frequentis A-NMS (ATM Network Management System) provides a centralised umbrella monitoring solution, delivering real-time situational awareness across all ATM communication networks. A-NMS consolidates performance monitoring, fault detection, and automated incident correlation, enabling ANSPs to maintain full visibility over their voice, data, and surveillance infrastructures. By integrating data from multiple network elements and vendors, A-NMS provides a unified operational picture, eliminating the inefficiencies of fragmented network management tools. 

Traditional ATM network monitoring solutions often react to failures rather than preventing them, leading to delayed fault resolution and increased service disruptions. A-NMS enables a proactive approach, continuously monitoring key network performance indicators (KPIs) such as latency, jitter, packet loss, and availability metrics for both legacy and IP-based communication services. By utilising real-time data collection and intelligent event correlation, A-NMS detects anomalies and degradation trends before they impact operations. If a critical ATM service experiences performance deterioration, the system automatically triggers alerts, provides root cause analysis, and suggests corrective actions. This enables network teams to address potential failures before they escalate, minimising disruptions to safety-critical communication links. 

End-to-end service management with application-aware monitoring 

In modern ATM environments, network performance must be evaluated from an operational perspective rather than focusing solely on infrastructure status. A-NMS provides application-aware monitoring, ensuring that voice, surveillance, and data services are assessed based on actual service quality rather than raw network parameters. This enables ANSPs to track service-level agreements (SLAs) effectively and prioritise actions based on operational impact. A-NMS also integrates historical data analysis and predictive modelling, allowing ANSPs to identify long-term performance trends and optimise network capacity planning. This helps reduce unplanned outages and improve overall network efficiency, ensuring that safety-critical communications remain stable and uninterrupted. 

Centralised control and integration with ATM-grade networks 

Beyond monitoring, A-NMS provides centralised control capabilities, enabling remote configuration, automated fault resolution, and seamless integration with ATM-grade network components such as NetBroker, VCX-IP, and SDDS-NG. By unifying management across voice, data, and surveillance infrastructures, A-NMS eliminates operational silos and allows ANSPs to streamline network operations, reduce maintenance costs, and enhance overall service reliability. With A-NMS and ATM-grade network monitoring, ANSPs gain full situational awareness, proactive fault management, and enhanced service continuity, ensuring that air traffic control operations remain safe, efficient, and resilient even in complex and dynamic network environments.
