The session border controller provides secure, high-quality voice, video and multimedia communications between access and core networks, enabling fixed and mobile operators to offer new services and increase revenues while reducing operating expenses. Its security features protects core network resources and subscribers from malicious attacks while ensuring connectivity to networks that use private or un-routable addressing schemes.
Since VoIP networks are typically built as "island networks," the session border controller's advanced routing services ensure connectivity, while session admission, overload and transport controls minimize network congestion allowing operators to meet or exceed customer QoE/QoS expectations. The NS-8A standard ATCA platform and modular design makes it easy for operators to scale to meet their growing subscriber base while it's full modular redundancy ensures the 99.999% availability required for carrier-grade systems.
