Rich Features and High Flexibility in Bosth PSTN and IP Networks

Configurable for E1/T1 VoIP gateway funtion, this SBC model supports voice densities in PSTN networks(E1/T1), call routing, call translation and IP transcoding for gateway operations. The integrated gateway functionality not only provides interworking between IP and TDM domains, but also automated failover from IP to TDM for outbound routing. These capabilities make this device an excellent option for mobile VAS, SIP trunking, contact center, service providers, enterprises & carriers.

Hybrid IP & PSTN Architecture Combined With Unparalleled Functionalities

This device supports voice densities up to 1000 channels (E1/T1), call routing, call translation and IP transcoding for gateway operations. The integrated gateway functionality not only provides interworking between IP and TDM domains, but also automated failover from IP to TDM for outbound routing. These capabilities make this device an excellent option for mobile VAS, SIP trunking, contact center and emergency service deployments, as well as for retail, wholesale and business.

Features

High Interoperability
Adopted by over 500 SPs and enterprises, and proven interoperability with SIP trunks, SIP platforms and IP cloud services

Enhanced Security
Security-oriented, robust perimeter defense against cyber, DoS and DDoS attacks, as well as eavesdropping, fraud and service theft

High Resiliency
Telco-grade reliability, with High Availability (HA) using 1+1 active/standby redundancy, local branch survivability and PSTN fallback

Integrated Transcoding
Eliminate need to add separate hardware to support transcoding requirements, and support a range of Codecs, including G.723, G.729, G.711, iLBC, SIPINFO, RFC2833, RF3261, INBOUND and more.

Improved Integration
SBC bridges operators with enterprise communication networks seamlessly, rationalizes traffic, streamlines business procedures, and optimizes SIP trunking, PBX/H.323/SIP and VoIP applications.

Capabilities

Flexible Scalability
5 ~ 1000 simultaneous SIP sessions with dedicated DSP-powered multimedia transcoding provide high performance in a small footprint to help lower ownership cost and reassure high security at borders.

Deliver Hi-Flexibility
Secure connectivity and controlling can be offered by SBC1000H (E1/SIP), as it efficiently supports bilateral and multilateral interconnection among different networks; besides, Dialing and IP/PSTN routing available.

Superior Voice Quality
Integrate decades of SW/HW technologies to obtain advanced capabilities for optimizing and monitoring voice service quality

Loading Optimization
Load protection at the border of network provides highly differentiated voice and multimedia services through multi-level resource-balancing policies, registration limit, ID authentication and authorization.

Enhanced Security
SBC1000H (E1/SIP) offers real-time communication surveillance solution for enterprises/SPs/carriers communication systems, and helps them deliver any business-driven applications effortlessly and safely.
