C3 Gateway Controller

GENBAND Difference

GENBAND's C3 Gateway and Media Resource Function Controller enables a new level of IP communications reliability, flexibility and scalability for network operators.

Deployed worldwide and operating with GENBAND’s G9, G6, and G2 IP gateways, the C3 is a multi-application softswitch and media server/media gateway control platform that allows operators to cap-and-grow, or replace their TDM switches and launch cost-effective greenfield IP Trunking, IP interconnect, and IMS applications.

The GENBAND C3 softswitch provides extensive capabilities and features to support IP routing, IP packet filtering and call handling, and support of MGCP or H.248 media gateways.

Benefits

• Versatile softswitch for ILECs/PTTs, CLECs, IOCs and Wireless operators
• Integrated functions reduce network complexity and enable network, floor space and power savings
• Cost savings through concurrent support for Class 4 IP Tandem, Long distance, international transit, gateway MSC, supplemental subscriber services, and IP-to-IP transcoding
• Open architecture with GENiUS platform evolution and standard interfaces avoids complexity of proprietary implementations
• Flexibility for standalone pre-IMS network deployments or operation with an IMS core
• Simplifies operations by enabling consistent feature sets across all wireless, wireline, TDM, IP, core and access networks
• Performs with the highest reliability, scalability and redundancy to ensure carrier-grade deployments
• Scales readily from small to large deployments with millions of busy hour call attempts supported using server or GENiUS platforms
• Comprehensive suite of IP routing capabilities

Overview

Wireless and Wireline Network Convergence: The C3 provides service convergence and feature transparency across a wide range of wireless and wireline core and access networks. Solutions supported by the C3 include IP Transcoding and Media Adaptation, Class 4 IP Trunking, International Transit, Long Distance Bypass, IMS PSTN gateway, Subscriber Services, Wireless Inter-MSC Trunking, and Gateway MSC.

Integrated Features for Simplicity and Cost Reduction: The C3 integrates media gateway and media server control, service logic, billing, regulatory, signaling, service creation, and element management within a common, scalable software and hardware environment, thereby reducing the need to deploy costly additional platforms. Its protocol-independent signaling and media control functions manage the interconnections between TDM and packet protocols, independent of incoming and outgoing facilities and signaling types.

Open Architecture and Standard Interfaces: Unlike proprietary platforms, the C3 provides open, standard access and trunking interfaces for signaling, management and line equipment/CPE, including SIP, SIP-I, SIP-T, H.323, H.248, MGCP, PRI, SIGTRAN, CAS/R2, SS7/C7, BICC, IS-41, AIN/IN, V5.2 and GR-303. This allows it to be an efficient, standards-based element that provides signaling interworking, call control and features, supporting distributed or centralized architectures to generate cost savings and new revenue from Voice-Over-IP enabled service offerings.

Extensive Feature Set: The C3 enables robust services for the most demanding environments. Class 4 Switch and IP Trunking features include comprehensive routing, translations, screening, database interface (toll-free, prepaid, etc.) and protocol interworking. An extensive set of subscriber features are also provided including an integrated SBC with per-session firewall, NAT learning, and dynamic ACL; Lawful Intercept; Number Portability; audio bridging/conferencing and emergency services.

Transcoding/MRF: Working in conjunction with GENBAND’s G9 Converged Gateway, the C3 is a media resource controller that enables direct IP-to-IP transcoding between disparate networks. Its extensive wireless and wireline codec support and SIP interfaces enable it to be an efficient centralized transcoding control platform for all networks, physically separating control from the media processing elements so that transcoding resources can be efficiently sized and scaled according to network needs.

Integrated GENView™ Network Management: The C3 has an integrated GENView Element Management System that enables remote and centralized OAM&P control of multiple C3 nodes and gateways via web-based terminals. It includes a suite of standards-based interfaces to support FCAPS functions.

Integrated CDR Collection:An easy-to-use, integrated CDR and IPDR collector is provided by the C3, allowing call detail records to be generated in both standard and user-definable formats.

Flexible Service Creation: The service creation environment available in the C3 can be used by operators for advanced service development. The platform also uses open interfaces to support off-board application servers and SCP systems via both AIN and SIP to enable other revenue-generating network services.

High Capacity Platform Architecture: Network-proven worldwide, the C3 supports millions of Busy Hour Call Attempts. The highly scalable C3 operates in small to large configurations. Operators can grow capacity as needed by simply adding pairs of C3 nodes to a deployed system, provisioning call processing and signaling across the complete C3 system for cost-effective network deployments.

IMS Compatibility: A flexible platform for standalone pre-IMS networks, the C3 can also operate in parallel with an IMS core or TISPAN networks to maximize investment protection. The C3 provides standard interfaces to IMS cores for media processing control as the Media Gateway Control Function and Media Resource Function Controller.

Carrier-Grade Platform: The C3 software is deployed in high-availability distributed clusters using one or more pairs of standard, carrier-grade servers. The C3 supports fully-redundant network deployments as well as geographic redundancy via its distributed software architecture.
