This document discusses power utility challenges in migrating from legacy telecommunications networks to next-generation packet networks. It outlines the need to replace obsolete equipment while maintaining interoperability with existing infrastructure. It also addresses challenges around terminating analog/leased line services and introducing new packet-based services. RAD solutions are presented as addressing these challenges through hybrid TDM/packet networks, carrier-grade Ethernet, and evolutionary migration paths to facilitate a smooth transition while ensuring network reliability, security and future scalability.
