Next Generation Networks
The next-generation network has the potential to seamlessly blend the public switched telephone network with both public and private data networks into a single multiservice network. In response, service providers are aggressively deploying a new generation of cost-effective, open systems architectures that promise to transform the telecommunications market in the same way that personal computers changed enterprise networking. But to compete and win in this competitive environment, carriers must offer revenue-generating enhanced services ahead of the competition, reduce up-front costs, preserve investments in existing infrastructure, future-proof new deployments, and provide a high degree of scalability.

Intelligent, Flexible, and High Performance with 10G Fabric Support
The iNAV® 31K-G2 AdvancedMC Carrier Card is a flexible, high-performance addition to next-generation systems. It meets the needs of a wide variety of applications in ATCA 3.1 systems, including I/O, processing, and storage. The iNAV 31K-G2 features include a high-performance Ethernet switch with 24 gigabit ports and up to two 10 gigabit ports, an optional PCI Express switch, advanced Telecom Clock management, and a Linux®-based Board Management Processor that provides full local and remote management.
