D2 is working with a number of SoC partners to develop integrated software solutions for end-point telecom products such as Terminal Adaptors, IP phones, WiFi handsets, VoIP residential gateways, base stations and access points. These partnerships lead to reference designs that include the hardware as well as integrated software for a working application. These reference designs serve as a basis for final end product design and development. Contact D2 Sales for more information and a complete list of vPort reference designs.
