FOX615 Multiservice Platform, developed by Hitachi Energy, is a robust solution designed to meet the critical communication needs of power transmission and distribution networks. It ensures seamless extension of existing infrastructures while enabling a smooth migration toward future-proof technologies. The platform supports teleprotection interfaces in both SDH and MPLS-TP networks and, with its IEC 61850 interface, can act as an Intelligent Electronic Device (IED), enabling GOOSE-based protection applications. Built to withstand harsh environmental conditions such as extreme temperatures, magnetic fields, and electrical stress, FOX615 is tailored for demanding utility environments .
FOX615 Multiservice Platform, developed by Hitachi Energy, is a robust solution designed to meet the critical communication needs of power transmission and distribution networks.

The platform supports teleprotection interfaces in both SDH and MPLS-TP networks and, with its IEC 61850 interface, can act as an Intelligent Electronic Device (IED), enabling GOOSE-based protection applications. Built to withstand harsh environmental conditions such as extreme temperatures, magnetic fields, and electrical stress, FOX615 is tailored for demanding utility environments .
The platform supports hybrid networking, combining traditional TDM/SDH with next-generation MPLS-TP packet switching. This makes it ideal for critical applications such as protection relays, SCADA systems, and wide-area protection schemes, where parameters like latency, symmetry, and reliability are vital. FOX615 can operate simultaneously across SDH and MPLS-TP domains, allowing flexible deployment strategies based on traffic and network requirements .
For teleprotection, FOX615 provides interfaces for distance and differential protection schemes. Specialized interface cards such as TEPI2 and OPIC2 allow these applications to run reliably over SDH or MPLS-TP, addressing challenges such as delay, jitter, and wander in packet-based networks. Functions include compliance with IEC 60834-1, channel supervision, event recording, and fast protection switching for dependable operation .
Synchronization and timing services are also well supported. FOX615 distributes Time-of-Day signals, integrates with external or station clocks, and ensures high-precision timing for applications like IEC 61850 GOOSE messaging. These capabilities are critical for time-sensitive operations in modern substations .
Security is a cornerstone of FOX615. It follows a “defense-in-depth” approach, offering authentication to prevent data modification, resilience against denial-of-service attacks, encryption for confidentiality, and centralized account management. MPLS-TP’s static channel routing and the inherently limited protocol exposure of SDH further enhance the system’s cybersecurity posture .
FOXMAN-UN, the integrated network management system, provides centralized control. It allows real-time monitoring of synchronization status, performance metrics, firmware distribution, and automated or scheduled updates. Its graphical user interface simplifies channel configuration, fault management, and alarm supervision .
By supporting both legacy SDH/PDH infrastructures and modern MPLS-TP and IEC 61850 standards, FOX615 offers strong investment protection. Utilities can modernize step by step, preserving existing assets while preparing for future digital communication requirements .
