Calix announced the addition of end-to-end Internet Protocol Version 6 (IPv6) support within the Intelligent Access EDGE solution. It enables broadband service providers to eliminate the high costs and challenges of expanding their networks using IPv4 addresses to meet accelerating subscriber demand. With this new ability to route IPv6, BSPs gain the benefit of a network that is both extremely scalable and secure all the way to the subscriber premises. San Luis Valley Rural Electric Cooperative broadband subsidiary Ciello sought to expand its network to cover more of its southern Colorado footprint.
