WESTWAVE COMMUNICATIONS' V-SWITCH ACCESS SOFTSWITCH OPENS SERVICE PROVIDER NETWORKS.

Westwave Communications Inc., the developer of the world's first standards-based access softswitch, has unveiled its powerful new V-Switch access softswitch for carrier next generation networks. The V-Switch is a revolutionary new type of softswitch that provides call control and signaling for access devices at the network edge. The V-Switch is a breakthrough switching product that enables next generation digital loop carriers (NGDLCs) to operate independently of the Class 5 switch by providing dial tone and services directly to the access device. The V-Switch is currently engaged in multiple service provider trials.

"The V-Switch is a one-of-a-kind, fully featured software solution that costs significantly less to deploy than traditional switching technology," says Dave Ehreth, President and CEO, Westwave Communications. "With our access softswitch, carriers can leverage their existing multi-billion dollar investment in access infrastructure to offer new next generation voice and packet services. For increased flexibility, the V-Switch is engineered to allow service providers to migrate customers on a one-by-one basis."

Westwave's access softswitch is standards-based and interoperates with best-of-class next generation access equipment including NGDLCs and media gateways. The V-Switch operates alongside existing Class 5 switches to provide enhanced features or can function as a Class 5 switch alternative.

Access Switching is the latest in softswitch technology and enables access devices, such as the widely deployed Alcatel Litespan, to function as a Class 5 switch, media gateway and as a NGDLC. The V-Switch provides dial tone and traditional services including call waiting, caller-ID, call forwarding, end-office switch call control and a signaling interface to the PSTN SS7 network at a fraction of the cost of traditional solutions.

The V-Switch also supports an internet offload trunkside application in conjunction with Rapid5 Networks' RCP-700 media gateway. This application relieves network dial-up traffic congestion from Class 5 switches. With PRI offload, carriers can save 20-80% over traditional circuit switch technologies and also increase their margins on highly competitive services. Existing network resources can be leveraged to save on capital and operating expenses by providing lower cost ISUP trunks to replace expensive Class 5 PRI links.

"Deploying the V-Switch in the access network costs significantly less than to forklift or upgrade existing legacy infrastructure," said Thom Baker, Vice President Marketing, Westwave Communications. "With the Westwave switch, service providers have access to the same traditional switching functionality but with improved switching performance and opportunity for new revenue opportunities. Carriers can be more competitive and profitable while making a seamless transition to packetization and voice over IP services."

Westwave's platform supports a standard-based open access architecture, which enables low cost migration of voice networks to next generation packet-based services. The architecture, comprised of three logically separate layers, separates physical control of the access network from the logical control of its services.

The Media Layer - The media layer defines service delivery and consists of access devices, such as NGDLCs, digital subscriber line access multiplexers (DSLAMs), voice-over-DSL gateways, and media/trunking gateways. The access switch (V-Switch) supplies all control and intelligence to these access devices.

The Control Layer - The control layer, or access switching layer, handles call control and signaling functionality and acts as a mediator between the other two layers. The signaling system (SS7) and other softswitches also operate within this layer. The access softswitch enables converged services via APIs and connects calls to or from the public switched telephone network (PSTN).

Applications Layer - The applications layer supports feature servers, application servers, and Application Service Providers (ASPs). Working through standard interfaces, service providers via the access softswitch, have access to transparent next generation services and applications.

The V-Switch Access Softswitch is commercially available today.
