• the possibility of a fully redundant configurations (High Reliability);,
• stations interconnection via Gigabit Ethernet and VoIP subsystems,
• interfacing with legacy systems

• interfacing to the higher hierarchical levels of the railway telecommunications network,
• compatibility with systems provided by different suppliers.
