Ribbon Q21 Session Border Controller's Features
  • Smart Management
    • Accompanying the Ribbon Q21 SBC is the market leading GENView Real Time Session Management tool (RSM) a smart management solution that simplifies day-to-day operations. The RSM monitors, analyzes, reports, and enforces quality and performance at the network borders, providing visibility into edge traffic along with the ability to dynamically modify call-routing behavior based on a combination of business policies, network QoS, and subscriber usage patterns. The RSM offers user a web-based provisioning interface with simple drop down menus and configuration templates for vendor- specific profiles, enabling faster time-to-market for services.
  • Smart Analytics
    • The powerful Ribbon GENView Analytics tool enables operators to easily monitor network wide performance and end to end service quality, in order to quickly troubleshoot and resolve network problems. GENView Analytics unique intuitive and interactive interface uses customizable dashboards to visualize and analyze performance metrics. Dashboards can be custom made to suit operator use cases such as Security & Fraud, Quality Assurance, System Resource monitoring and service utilization, and call troubleshooting diagrams.
  • Delivering Holistic Visibility and Dynamic Adaptation
    • Quality/QoS Monitoring: providing visibility into how the network is delivering service
    • Comprehensive Reporting: exposing historic and real-time network performance.
    • Business Reporting: providing visibility into route profitability.
    • Adaptive Call Routing: re-shaping routing policies to ensure network quality targets are met.
    • Advanced Call Diagnostics: enabling views into sessions that may straddle multiple SBCs.
  • Multi-Dimension Adaptability
    • Delivered on a “commercial off the shelf” (COTS) 2RU server platform, and using media processing in software, not hardware, the Ribbon Q21 SBC provides substantial and measurable deployment benefits at a price/ performance ratio that leads the industry. Combining the advantages of a software-centric architecture, and flexible deployment options, the Ribbon Q21 SBC addresses a wide-range of performance needs while ensuring lowest total cost of ownership (TCO).
    • The Q21 is ideal for large carrier or service provider environments, yet equally well suited to medium service providers and enterprises, who are looking for high scale and density, with high session capacity and media throughput. It is easily capable of supporting up to 70,000 concurrent VoIP sessions in a small footprint, and offers market leading energy efficiency to drive significant reduction in energy usage and data center costs.
    • Ribbon's portfolio of appliance-based SBC’s are available as a best-of-breed carrier-grade, stand-alone SBC on a family of rack mount COTS servers. The SBC leverages common software across all versions of target hardware options, offering deployment flexibility, and the ability to seamlessly grow the network as needed.
