With an integrated enterprise SBC (Session Border Controller), the Sonus SBC 1000 offers enterprise branch and small and medium businesses optimized SIP Trunking services for Internet Telephony Service Provider ( ITSP) connectivity.

• Complete enterprise/ ITSP demarcation point services, such as network topology hiding, transcoding, IP transport conversion (TCP <-> UDP),and signaling/media encryption (TCP<->TLS/RTP <->SRTP)
• Multi-ITSP registration, with optimized routing, including cost or service quality / availability
• Built-in Network Address Translation (NAT), prevention Denial of Service (DOS) and Distributed Denial of Service (DDOS) attacks

Branch Office Connectivity and Survivability for Microsoft Lync Server 2010

The Sonus SBC 1000 Survivable Branch Appliance (SBA) provides basic voice services to branch office users during a WAN outage. During a WAN outage, the SBA appliance manages the intra-branch voice calls and IM sessions as well as inter-branch communications and voice mail retrieval over PSTN. The Sonus SBC 1000 Benefits:

• Multiservice Router and VoIP gateway with Branch office Survivability
• Session Border Controller with NAT function, Network topology hiding, and Security
• Continued branch office operations through WAN failure
• Also configurable as a stand-alone office primary Lync server

Highly flexible connections for SIP, legacy PBX, analog, and PSTN

The Sonus SBC 1000 offers true “any-to-any” signaling translation and media interworking between SIP, analog, and TDM endpoints. The Sonus SBC 1000 can simultaneously connect to legacy TDM PBXs and the PSTN through 2 T1/E1 PRI ports and up to 24 FXO. In addition, up to 24FXS ports are available for fax and low cost analog phones. BRI ports are also supported, and may exist alongside the FXS, FXO, and PRI ports to provide complete analog/TDM device integration into a branch office’s Lync topology.

In parallel, the Sonus SBC 1000 also interconnects IP-based endpoints (i.e. IP-PBXs, non-Lync SIP clients) and public VoIP networks (e.g. ITSPs) to the Lync clients. And, with Sonus’ optional applications, there’s no need to replace your legacy non-Lync SIP clients; the Sonus SBC 1000 can report non-Lync SIP client user states (e.g. presence, user busy, etc.) to Lync clients.

Architecture and Modularity

The Sonus SBC 1000 can scale up to 100 simultaneous sessions.

The Sonus SBC 1000 provides interoperability with Sonus VX Series Voice Exchange and Quintum media gateway products while supporting the transparent “drop-in” installation methodology for the upstream deployment model that was pioneered by Sonus. Sonus platforms are specifically designed to support upstream deployments with advanced features that give customers the highest levels of flexibility, scalability, quality of experience (QoE) and investment protection.

The Sonus SBC 1000 offers powerful quality of experience features, industry leading voice quality, intelligent call routing, call forking, and comprehensive PBX interoperability. Directory-based call routing is built directly into the SBC platform. The SBC also features a multi-mode user interface that provides configuration and real-time management of SBC nodes. The web-based user interface is designed to simplify and accelerate installation using a “task” configuration mode.
