DECT/Cordless VoIP

• SIP-based for ITSP

FMC/Dual-Mode Phone

• IM/P2P Voice
(stand-alone, w/o PC)

Cordless phones are mainstream in many environments including both residential and business settings.  The Digital Enhanced Cordless Telecommunications (DECT) standard dominates the cordless phone industry.  DECT based cordless phones can be enhanced to provide VoIP and IM functionality.  The base station of a DECT phone can be designed to access the Internet instead of a standard PSTN interface to provide VoIP or VoIM capabilities.  To achieve this, VoIP software is added to the cordless base station and the interface to the handsets is enhanced to accommodate new features such as presence/contact lists.

The vPort CP software solution of D2’s vPort product family provides ODMs/OEMs with an optimized VoIP solution for the new breed of cordless phones that support VoIP/VoIM capabilities.  It augments the excellent voice quality provided by the vPort engine with the specific functionality required for the cordless phone application.  vPort CP also minimizes memory and CPU impact for low cost implementation.  It is a proven solution with leading voice quality, performance and interoperability.

D2’s vPort Product Family

vPort leads the market in performance and efficiency, enabling networking, signaling and voice processing functions to execute as an integrated solution on a single processor. This in turn offers substantial advantages in bill-of-materials (BOM) cost, power consumption and ease of integration. The software is highly optimized not just for voice quality, but also for a small memory footprint, low processor (CPU MHz) impact and low latency, and adds true real-time performance to non-real-time OSs.

Designed for flexibility and portability, vPort can execute on both RISC and CISC platforms under industry-standard operating systems. It is currently optimized for both ARM and MIPS processor architectures under the VxWorks, Nucleus and LINUX operating systems. vPort’s virtual DSP architecture enables the voice DSP functions to run as “soft DSP” on a RISC processor or as DSP code on a hardware DSP core, providing further design flexibility.

The support of multiple processor architectures and OSs, along with the unique virtual DSP capability, allows OEMs to choose best-of-breed components and avoid being locked into a particular hardware platform or architecture. It also simplifies software development, support and maintenance, since all the software operates under a single environment using one set of tools. Because of its modular architecture, vPort can be quickly modified for customer-specific applications and runtime platforms.
