RTDI-451 4G/LTE

RTDI-451 ensures higly secured communications to electricity transport and distribution substations over a 4G/LTE connection.

RTDI-451 delivers all interfaces required to connect the substation equipment in compliance with the IEC-61850-3 requirements.

RTDI-451 provides unequalled level of cybersecurity to Utility mission critical networks. Utility communications are secured by IPSec tunnels that are authenticated and encrypted by most robust AES protocols.

RTDI-451 embeds a Secure-Element that secures all critical information such as X509 certificates for IPSec communications. It works with the enterprise PKI to securely refresh X509 certificates through the SCEP protocol.

All software modules are encrypted and authenticated at boot time to guaranty their integrity before execution.

Thanks to those cybersecurity features and higher isolation interfaces, RTDI-451 is a perfect communication for the electricity networks:

• Smart Grid
• MV/LV substations
• Regional electicity distribution companies
• Wind famrs
• Solar generation
• but also many other mission critical networks: railway, oil and gas, water distribution, etc.

RTDI-455 embeds a FXS telephone interface and a multimode modem that complies with the ITU-T V21 to V34 standards. It emulates the PSTN Public Switched Telephone Network and modem communication to the central server to carry the application data over the IP network through secured VPN communications.

RTDI-455 enables flexible migration of existing PSTN applications to secured and adapted IP communications over the 4G/LTE mobile network.
