Investor-Owned (IO) utilities have a networking challenge and opportunity. They must evolve away from their outdated Time Division Multiplexer (TDM) networks, which are no longer sustainable, and migrate to modern systems that use Routing and Switching technologies. Fortunately, the transition can be smooth and convenient for a utility. And once the network is established, the utility can also use the infrastructure  to offer new revenue-generating, carrier-grade broadband services to the customer base.
