• Secured data communication in packet-switched networks

FOX605 ensures reliable data transmission of mission-critical information under any network

circumstance. In operational networks any intrusion or unauthorized access could influence the

performance of the complete network, therefore special measures for protection are required.

The End2End data encryption and authentication functionalities of FOX605 guarantee that

mission-critical information is protected.

Migrating mission-critical services (e.g. teleprotection) to packet-switched networks while keeping

existing infrastructure untouched is supported by MPLS-TP which, in contrast to other

 packet-switched technologies like IP/MPLS, takes care of bidirectional paths and predictable

data traffic, thus guaranteeing the required performance of critical applications.

• Constant connection and information

The performance and reliability of the communication network are significantly increased by time

and phase synchronization through the WAN using SyncE and IEEE1588v2 (PTP).

With real-time distribution from a central master clock to all connected devices in the network FOX605

provides visibility and control of all activities in the network. With MPLS-TP reliable and dependable

data traffic under any network circumstance can also be guaranteed in packet-switched networks.

Integrated traffic generator and analytical functionalities allow seamless performance monitoring

according RFC2544 and Y.1564.

Additional benefits:

• Cost-efficient solution with a comprehensive feature set ideal for the first mile and access applications

• Stepwise introduction of Ethernet/MPLS-TP based applications in operational networks

• Secured data traffic in packet-switched networks

• Reliable data transport under any network circumstance

• Time and phase synchronization through the WAN

• Utility-grade design with fanless operation for deployment in harsh environments

• Fully interoperable with FOX family

Benefits

• Future-proof, long-term support of proven technologies

The long-term support of both traditional TDM and packet-switched technology MPLS-TP

in FOX605 enables stepwise migration or extensions of existing communication infrastructures

so that utilities can evolve to future communication networks securely and with the expertise

of a long-term partner. With FOX605 new applications can be easily and securely added to

the existing operational network. As soon as the utility decides to migrate, the comprehensive

feature set of FOX605 offers all the required functionalities already today. Like all other FOX

products, FOX605 can be easily configured and managed with the network management

system FOXMAN-UN.

• Robust communication solutions for utility-specific applications

Hitachi Energy’s FOX605 comes with a comprehensive feature set in one single box, making it

the ideal solution for the first mile and access applications. The support of traditional interfaces

ensures a diversity of connection possibilities in one operational network. The combination of a

circuit- and packet-switched technology, including MPLS-TP, offers flexible migration and extension

of existing communication infrastructures. Built-in data encryption and authentication functionalities

for WAN communication enable secured data traffic between remote stations.

The utility-grade design, including a high-temperature range, makes FOX605 ideal for indoor and

outdoor installation.

Utility environment:

These days most offices grind to a halt in the face of a failed internet connection, but no industry

compares to electrical transmission in being dependent on robust, resilient, and predictable

communications. Only suppliers with an intimate knowledge of the industry can supply,

and maintain, equipment capable of meeting that unique set of demands.

In addition to extremes of temperature, utility communications equipment is also exposed to magnetic

and electrical fields, which are particularly severe during short-circuit events.

In order to maintain the high levels of availability required, especially in emergency situations,

utility communications equipment must offer a robust and reliable design that has proven

capabilities for providing accurate functionality under extreme conditions.

In dusty and remote environments, where regular maintenance cannot be guaranteed,

fan-less designs are preferable.

Cybersecurity: Layered communication architectures ensure improved network security.

Packet-based networks use publicly documented protocols, and utilities are potential targets,

so a comprehensive (and co-ordinated) security policy is essential across the entire network.

Depending on the application requirements, different measures need to be taken, starting from

denial of service protection, protection against data modification using authentication,

up to encryption of confidential data, and centralized user account management.

This ensures a ‘defense in depth’ approach and is supported by the FOX615 platform.

Additionally, the static approach of MPLS-TP, with much fewer protocols being potential targets

for attacks, and the natively integrated SDH technology reduce potential attack surfaces.

Longevity: Investment cycles in utilities are much longer than those in the public telecom sector.

Protection and control equipment in electrical substations, which is ultimately connected to

utility communication equipment, is particularly long-lived. The ultimate goal of commissioning

an all-Ethernet/IP network is still far away, particularly for Hitachi Energy, which link hundreds

or even thousands of established substations.

A basic requirement of such a system would be longevity, with guaranteed performance as per

established technologies. Unlike the full network refurbishments often seen in public

telecommunications networks, utility networks evolve slowly, increasing in size and slowly

migrating to new technologies in a step-by-step approach. This evolution means that high

interoperability between existing and new installations as well as parallel operation of both is a must.

Overview

Ready for the challenges of tomorrow

FOX615 integrates teleprotection interfaces for distance as well as for differential

protection simultaneously within state-of-the-art SDH networks and MPLS-TP networks;

ensuring an easy and flexible way to migrate technology in a utility network.

With its latest IEC61850 interface the FOX615 also acts as a substation IED and

enables GOOSE based protection applications of digital substations.

Built on Hitachi Energy’s huge domain expertise, the utility-grade design of FOX615

is deployed in thousands of installations across the globe with guaranteed performance

including those with electromagnetically polluted environments and across a broad range

of temperatures.

Teleprotection: Safeguarding the electrical grid

Critical to grid operations is the protection of power lines, through teleprotection.

Teleprotection systems were developed alongside the electrical grids themselves,

and the operational communication networks used are mainly driven by those applications.

In 1940. the average telephone user was just getting to grips with the rotary-dial telephone,

while Hitachi Energy was deploying power-line communications: utilizing the electrical

transmission infrastructure to carry teleprotection data and avoiding the need for a separate Pilot Line.

Public telecom networks have evolved at an amazing speed, this has been primarily driven

by new applications (e.g. smartphones, YouTube, email) which results in a growing demand

for increased bandwidth. Subsequently this has resulted in network solutions with a higher

capacity for data transmission with a lower focus upon the quality of service.

Teleprotection systems, in contrast, have always operated under the pressure of protecting

critical infrastructure. Reliability and quality of service is paramount, resilience is required,

while new technologies and techniques must prove themselves robust enough to match,

or exceed, the existing equipment before they can safely be used in the electrical network.
