Integration and convergence continue to be significant trends in customer premise equipment (CPE).  Functions such as DSL/Cable modem, wireless routers, and VoIP, VoWiFi, VoLTE Analog Telephony Adapters (ATAs) are merging together to from a single Integrated Access Device (IAD).  The WAN connection is moving beyond ADSL and Cable to even higher speed broadband technologies such as PON, GPON, FTTH, and VDSL2. 

These higher speed connections will allow even more services to be offered over broadband.  VoIP is key element of these new services and is becoming a standard offering.  As a result, VoIP, VoWiFi, VoLTE ATA functionality is being added to many types of next-generation CPE devices.  To succeed in this competitive market, it is crucial to have excellent VoIP quality, reliability and robustness, as well as the integration flexibility to enable integration in a variety of environments.

The vPort GW software solution of D2’s vPort product family provides ODMs/OEMs with an optimized VoIP solution for CPE devices such as gateways, routers and IADs.  It augments the excellent voice quality provided by the vPort engine with the specific functionality required for the IP gateway application.  vPort GW 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.
