Sonus SBC 5200™ Session Border Controller
The shift to multimedia/multidevice communication requires a new generation of session border Controller (SBC): one that looks beyond simple border mediation to a broader world of seamless, service-rich interoperability. The Sonus SBC 5200 Session Border Controller series addresses the next-generation needs of Session Initiation Protocol (SIP) communications by delivering media transcoding, robust security and advanced call routing in a high-performance, small form-factor device. The SBC 5200 series is available in two form factors: modular (SBC 5210) and fixed (SBC 5200).
The Sonus SBC 5200 series enables service providers and enterprises to quickly and securely enhance their network by implementing new services like SIP trunking, secure Unified Communications and Voice over IP (VoIP). Leveraging the longstanding strengths of the Sonus SBC 9000 Session Border Controller—security, session control, bandwidth management, advanced media services and integrated billing/reporting tools – the SBC 5200 series delivers pure IP-to-IP interconnect with a network edge like no other:
- Unique design with embedded transcoding/encryption processing for un-beatable real-world performance and scalability
- Advanced policy and routing intelligence via an embedded PSX engine or centralized PSX policy 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, modular or fixed digital signal processor (DSP) firmware
Miercom Performance Verifie
The peering and access performance capabilities of the Sonus SBC 5200 series have been Miercom Performance verified. Read the full report here.
- SBC 5200 successfully registered 256,000 user authenticated Total IADs in 16 minutes at a rate of 550 registrations per second during a simulated metro area outage and recovery scenario.
- The SBC 5200 demonstrated outstanding CPU and Allocated Memory utilization throughout all tests. Miercom observed that these resources were rarely stressed and never maximized.
- Sonus SBC 5200 maintains scalable call processing while under attack from spoofed IPs. In a maximum configuration, it supports up to 64,000 concurrent calls.
The SBC 5210 is built on the same proven hardware architecture and software as the SBC 5200. As part of the product evolution, the SBC 5210 adopts a modular design that allows customers to install up to four DSP cards and is field upgradeable as network demands change.
Best-in-Class Performance Density
The SBC 5200 Series 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 SBC 5200 Series 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 SBC 5200 – 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.
The SBC 5200 series is available in two form factors: modular (SBC 5210) and fixed (SBC 5200).
The Sonus SBC 5200 provides integrated media services including media transcoding, DTMF relay and interworking, and support for data (modem) and T.38 fax relay or interworking.
With the SBC 5210, Sonus offers modular DSP20 and DSP25 cards. These cards, together with the SBC 5210, provide a substantial increase in DSP system capacity, giving customers greater support for border-based media control and services such as DTMF relay and interworking and support for data (modem) and T.38 fax relay.
Feature-Rich Interworking across Voice, Video and Collaboration
The Sonus SBC 5200 delivers true multimedia SBC support for voice, video and collaboration with advanced security and session management capabilities. Sonus SBCs help break down silos and integrate a company’s video endpoints by interworking different protocols and devices to enable one seamless end-to-end video experience. Sonus is the only vendor in the market with the ability to provide video interworking among endpoints from various vendors without compromising SBC performance or scale. By enabling interoperability between video endpoints, Sonus SBCs help companies maximize current video investments while providing the freedom for businesses to use the devices of their choice without being locked into one vendor or endpoint device.
QoS/Service Level Assurance
In order to ensure the highest quality of service, the SBC 5200 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 with regards to 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 SBC 5200 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.
