QATS SIGNALLING

QATS Signalling is a product developed purely for the monitoring and troubleshooting of ERTMS and interlocking. It detects and analyzes malfunctions affecting railway operators’ overall quality of service, such as train run delays, end-of-session issues and other metrics.

  • Monitoring : ETCS Level 2 and 3, Subset-093 and datalink KPIs for ETCS.
  • Standards : Eirene SRS, Eirene FRS, Subset-093 CS-PS, Subset-026, Subset-039, Eulynx, SCI and more.
  • Multiple traces : Real-time and/or historical end-to-end train run and session traces
  • Safety/emergency metrics : Detailed insights on M_MODE, M_ERROR, train trip, position, speed, and emergency stop data, as well as data recorded by juridical recording units (JRUs).
  • Dashboards : Customizable and dynamic web-based layouts with various metrics, including maps, tables, charts and graphs.
  • Filters : Easy and advanced filters for issue investigation.
  • Alerts : Proactive alerts on specific events, such as M_ERRORs, train trips, etc.
  • Reports : Scheduling features, email notification, various outputs and advanced SQL features on demand.

Tailored for ERTMS performance monitoring

It’s a question often asked by railway operators: Is my GSM-R/GPRS network ready for ETCS? By measuring all Subset-093 metrics based on real ETCS traffic, QATS Signalling can produce a comprehensive assessment of the network’s accessibility, retainability and integrity by measuring KPIs such as connection establishment delays/errors, the connection loss rate and many other metrics.


Balise error detection

QATS Signalling monitors all updates during an ETCS train run in Level 2, such as balise group reference ID and location. It is also able to detect several errors related to balise group reading and treating. Troubleshooting and triggering features are there to alert if a balise group has generated a message consistency error, or if a balise group linking error occurs. (E.g. Missed balise group in an expected area)


A tool for detecting the cause of train delays

With QATS Signalling, operators are able to determine whether or not a train delay is the result of an ETCS issue. The solution can be used either proactively or in response to a detected issue by comparing any current train run with a reference timetable. QATS Signalling can instantly detect and locate a train delayed by more than five minutes.


QATS Signalling includes multiple features which are constantly improved based on user feedback. Main features include:

  • Tracing-specific features
  • ETCS Traffic/Session management features
  • Trip emergency, M_ERROR, M_MODE, JRU metrics
  • Subset-093, Subset-026, HDLC frame analysis

Monitored Protocols
