The Architechture for Interoperability
ITxPT stands for “Information Technology for Public Transport”. Digitalisation brings many opportunities for public transport. The aim of the international association is to standardise IT systems from proprietary to open, integrated architectures based on established standards. ITxPT uses the well-established Internet Protocol (IP) as its basic communication standard. The standard plays a key role by enabling data exchange between and across all relevant public transport systems. ITxPT is relevant mainly for three groups: public transport authorities and operators, IT suppliers and vehicle manufacturers.
The Role of Ethernet Switches in ITxPT
Simplification of the board architecture
Separation and protection of sensitive data
Connection between all onboard systems
Cost reduction through simple maintenance
Legacy silo systems
Legacy systems are often found in existing vehicle fleets. These are proprietary systems that work with non-standard, vendor-based protocols. As a result, systems such as CCTV, passenger information, on-board payment or passenger counting systems are not interconnected and only work in silos. As a result, the on-board architecture becomes more complicated and requires more hardware (routers) and additional cabling, leading to higher acquisition and maintenance costs. In silo systems there is no significant need for Ethernet switches.
The foundation of integrated systems is the interoperability between systems based on an integrated IP network in public transport vehicles. Once different systems in the vehicles are connected, data flows through a common network. Ethernet switches are essential as they provide the necessary infrastructure for data exchange between all connected systems. With the common IP network, new requirements for network management arise. Sensitive data (e.g. payment, CCTV) must be separated from the rest of the common network. In addition, the status of the network will be monitored to detect errors and problems at an early stage. Finally, the network must be easy and efficient to maintain without the need for IT expertise. To meet all these requirements, we put all our knowledge and skills into our ROQSTAR Ethernet Switches.
The ITxPT Label
To ensure the interoperability between devices and systems, ITxPT offers a test procedure in which IT modules, buses and supported software can be tested in accordance with the ITxPT standard. As a module supplier all our switches have been tested in an ITxPT laboratory. To make the conformity visible, the ITxPT association provides a label, which indicates that the module has been tested successfully. The official test reports are all available on our product pages.
All our ROQSTAR Ethernet switches meet the requirements of the ITxPT standard! In so doing, we support the interoperability between IT systems in public transport and thus fulfil our mission day after day: Make tomorrow’s mobility possible today.
Our products are fundamental for the digitalization in public transport. ROQSTAR M12 Ethernet Switches provide the network infrastructure for e-ticketing, passenger counting systems (PCS), dynamic passenger information (DPI) and closed-circuit television (CCTV).
