Passive monitoring


Process & Analyse True End-to-End ERTMS Transactions

Comtest Wireless passive monitoring solutions enable rail operators and equipment vendors to test and measure ERTMS, GSM-R and interlocking networks for true end-to-end signalling performance.

ERTMS networks are complex environments that present many monitoring challenges and issues, including:

  • GSM-R coverage needs to be available everywhere and at all times
  • Network supervision must be 24×7
  • The monitoring system needs to be able to evaluate complex systems interactions (GSM-R/ETCS/IXL)
  • The monitoring system must also identify root-causes, when anomalies occur
  • The data collected needs to be retained for a sufficient period of time to:
    • ensure that network upgrades can be properly tracked
    • perform appropriate rollbacks, in the case of malfunction
    • score performances and identify trends

Using scanners, responder units and other monitoring hardware, NetProbe passive monitoring enables signalling data streams from the trackside and on-board units to be collected in real-time from a wide variety of network and train equipment.
