Tennessee Valley Authority Deploys RAD’s Multiservice Access Platform

Replaces Existing Legacy Multiplexers and Aging Digital Cross Connects

Tennessee Valley Authority is deploying RAD’s purpose-built, cyber-secured multiservice access platform.

TVA is the second largest wholesale power producer in the United States, ultimately serving approximately nine million people across an 80,000 square-mile footprint that spans all or part of seven southeastern states, including Tennessee, Mississippi, Kentucky, Alabama, Georgia, North Carolina, and Virginia.

RAD’s multiservice access platform, one of the pillars of its Service Assured Networking (SAN) solutions, is a suitable fit for power utility migration projects. It will replace legacy multiplexers currently installed in TVA facilities to support a variety of services over critical infrastructure, including automation functionalities, along with a variety of low-speed, high-speed, and voice services. TVA has also selected the RAD solution to replace and update, aging digital cross connects.

While TVA’s communications services will continue to run over the self-maintained network, the RAD system offers a dual backplane that supports both circuit-switched and packet-switched networks either separately or concurrently. This will allow a smooth migration for implementing next-generation packet services, including Smart Grid applications, and anticipates the impending NERC-CIP v5 requirements for cyber security initiatives.

To bridge the gap between legacy and next-generation services, the RAD system could be used to deploy a solution that incorporates pseudowire emulation. Pseudowire, a technology pioneered by RAD, enables the transport of TDM traffic over IP/Ethernet networks.
