Multitel offers tests for a number of ERTMS contitutents and sub-components, including Eurocabs (EVC), Eurobalise, BTM (Balise Transmission Module) antennas, DMI (Driver Machine Interface) units, JRU (Juridical Recording Unit) units.
- EVC Laboratory Tests
The Eurocab MultiRailLab laboratory of Multitel has obtained ISO 17025 accreditation for EVC tests, for Subset-076-5-2 v2.3.1, Subset-076-6-3 v2.3.1, Subset-7 v1.0.2 and Subset-094 v2.0.2 from BELAC. Accreditation BELAC number 427-TEST granted on 22nd February 2011.
This accreditation is greatly due to the SA-TAV (Semi Automatic – Trip Analysis and Validation) tool developed by Multitel for the analysis of the Subset-076 results.
SA-TAV can also be used for the validation of track lines, either with the use of an EVC simulator or with commercial onboard units connected to the track simulator of Multitel. This is very useful to anticipate problems during the validation of track signalling implementation, operational rules deployment and conformity with the SRS, therefore reducing the cost of the expensive line tests.
- Eurobalise, BTM Laboratory Tests
Multitel is prepared to perform Subset-085 v2.2.2 tests of Eurobalises and BTM antennas. Additionally the Eurobalise MultiRailLab of Multitel provides MultiRailLab Balises for ERTMS laboratories, as well its signal MixerBoxes for the simulation of air-gap high speed telegram transmissions.
Automation of the ERTMS test bench laboratory based on subset 094 through the use of automatic image recognition and automated multiple process control (thus, reducing the supervision necessary for carrying out a full certification process).
Generic EVC hardware inteface Multitel develops hardware interfaces, compliant with subset 094 that can also directly connect to the onboard unit, thus avoiding the development of adaptation boxes that are used by the industry just once, during the certification process.
New tools to support ERTMS expert validation: Based on the expertise of Multitel in Image Processing acquired through more than 8 years of research in signal processing and Image processing, Multitel has developed the DMI Event Manager which enables to automatically recognize Driver Machine Interface Events recorded by a camera from the on-board DMI equipment as show in Figure 1 below.

- Using our EVC Test bench laboratory to bring services for onboard & track-side equipments certification (ERTMS)
- Using our DMI Event Manager to fasten the process of the validation of the test results from videos of DMI
- Rail QoS monitoring (including GSM-R)
- Using our Traffic Simulator to test and validate the communication and configuration of multiple on-board equipments with the track side infrastructure (RBC, Interlocking, …), to help improving the train regulation (automatic route setting) and to assess ERTMS line capacity
