Electric, gas and water utility companies operate robust internal communications networks to support the critical infrastructure they provide to their customers and in their communities. Driven by regulatory mandates such as the NERC (North American Electric Reliability Council) cyber security standards, IP-based smart-grid and substation automation trends, as well as the increased adoption of bandwidth-intensive applications such as video surveillance and BPL (Broadband over Power Line), these mission-critical networks are transforming to meet the demands of the 21st century.
Utilities and their competitive telecom subsidiaries (UTelcos) are increasing optical bandwidth capacity and migrating from TDM to packet-optimized networks to support new IP-based applications more efficiently. Ethernet technology is playing an increasingly important role in this his transition, which is affecting all aspects of their communications infrastructure including transport, corporate data LAN/WAN and voice systems, digital microwave, and control systems.
