The Sonus SBC 5100™ Session Border Controller
For years, the world’s largest service providers and enterprises have relied on Sonus session border controllers (SBCs) for secure SIP-based communications. Now, smaller service providers and enterprises have a reason to cheer: the Sonus SBC 5100. The Sonus SBC 5100 delivers many of the industry-leading capabilities of the Sonus SBC 5200—robust security, flexible SIP session routing & policy management, media transcoding—at a more attractive price/performance point for Tier 2/3 service providers and medium-to-large enterprises (250 to 10,000 concurrent sessions). With high-end features you won’t find in other “mid-sized” SBCs, the Sonus SBC 5100 allows regional service providers and medium-to-large enterprises to deliver a world-class communications experience designed for their world.
- Unique design with embedded transcoding/encryption processing for unbeatable real-world performance and scalability
- Advanced policy and routing intelligence - embedded or in an external routing server
- New IP-based multimedia services beyond VoIP (IM, presence, Web 2.0)
- Superior protection against network attacks, overload and outages while preserving stateful call handling
- A proven SIP trunking solution with support for multiple SIP variants from IP-PBX vendors
- Built-in media transcoding featuring custom-built DSP firmware

Best-in-Class Performance Density
Built on the SBC platform, the Sonus SBC 5100 employs the latest generation of network processors, computing processors and digital signal processors (DSPs) to deliver the highest performance density SBC on the market combined with integrated transcoding, media interworking and native support for IPv6 addressing.
The Sonus SBC 5100 is the first product to combine full SBC functionality with media interworking, an advanced routing and policy engine and multi-access security gateway features in a single two-rack unit (RU) form factor. This unique combination of functionality addresses the evolving SBC market requirements, replacing multiple disparate network elements with a single Sonus SBC 5100–without compromising scale or features.
A robust suite of security features is provided for both signaling and media. Encryption is available as TLS or IPSec for signaling and Secure RTP for media. Other security features include traffic policing, DoS and DDoS attack detection and blocking and rogue RTP protection.
With the ability to add optional DSP processing modules, the small form factor of the Sonus SBC 5100 also provides integrated media services including media transcoding, DTMF relay and interworking, and support for data (modem) and T.38 fax relay or interworking.
QoS/Service Level Assurance
In order to ensure the highest quality of service, the Sonus SBC 5100 offers a wide range of features. Call Admission Control (CAC) regulates the number of calls that are admitted into the system based upon policy decisions. Individual flows into the system are managed based on their bandwidth utilization and packet rate. Policy decisions allow packets to have their QoS parameters marked based upon carrier policy rather than those selected by the user. Registrations and calls are rate limited to prevent malicious or misbehaving endpoints from causing overload conditions. If overload conditions do occur, then the Sonus SBC 5100 maintains existing calls/registered endpoints, permits emergency and priority calls, while preventing new calls/new registrations from being admitted until the overload condition has passed.
