Platform Modularity
The SBC 5110 is built on the same proven hardware architecture and software as the SBC 5100. As part of the product evolution, the SBC 5110 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 Sonus SBC 5100 series employs the latest generation of network processors, computing processors and digital signal processors (DSPs) to deliver the industry-leading density combined with integrated transcoding, media interworking and native support for IPv6 addressing.
Multi-faceted
The Sonus SBC 5100 is the first series 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 or SBC 5110 –without compromising scale or features.
Secure
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, denial of service (DoS) and distributed denial of service (DDoS) attack detection and blocking and rogue RTP protection.
Onboard Transcoding
The SBC 5100 series is available in two form factors: modular (SBC 5110) and fixed (SBC 5100).
The Sonus SBC 5100 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 5110, Sonus offers modular DSP20 and DSP25 cards. These cards, together with the SBC 5110, 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.
QoS/Service Level Assurance
In order to ensure the highest quality of service (QoS), the Sonus SBC 5100 series 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 series 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.
