D2 Technologies’ vPort products are available for use by manufacturers in a wide variety of product segments covering consumer, enterprise and carrier devices. At the heart of each vPort solution is a proven core technology that has been successfully deployed for applications such as wired/wireless voice-enabled terminal adapters, routers and gateways as well as VoIP phones and mobile handsets. vPort products can be integrated into an existing product or a new device and can be optimized to specific end-user device requirements.

D2’s software solutions offer unique voice engine, protocol processing and system implementation optimizations that are critical in embedded devices such as the following.

WiFi Handsets (VoWLAN/WiFi)

VoWLAN is gaining popularity in the corporate world, at WiFi hotspots and in the home. These WiFi handsets integrate embedded VoIP software platforms and connect to the Internet using WiFi, bringing mobility to VoIP applications.  Although SIP-based handsets have been dominant in the market due to enterprise and VoIP service provider (ITSP) deployments, new handsets are coming to market that support VoIM (PC-based IM/P2P VoIP) services such as Skype.  As a result, embedded VoIP software must now support multiple services.  Pricing pressure on WiFi handsets are extreme due to the precedent set by decades of cordless phones offerings.  Low memory footprint and high MHz efficiency is crucial due to size, battery life, cost requirements. 

The vPort MP solution is an ideal VoIP solution for WiFi handsets and is designed to minimize memory, CPU and battery impact.

Dual Mode Phones & FMC (WiFi/WiMAX/Mobile)

Users are increasingly demanding integration and convergence of multiple devices and services. The emergence of cell phones and PDAs with WiFi connectivity is the first step towards combining VoIP communication with traditional cellular access. Dual-mode phones add VoWLAN capabilities to traditional mobile phone platforms to offer greater flexibility in voice access. Today, most dual-mode phones use WiFi, but integrated WiMAX mobile devices based on the IEEE 802.16e standard are also taking shape. Dual-mode phones enable the vision of Fixed-Mobile Convergence (FMC). The initial step utilized UMA technology, but increasingly mainstream FMC products will be based on SIP-based IMS technology.

vPort MP addresses the stringent criteria of a dual mode phone by providing excellent voice quality, low CPU utilization, and a small footprint. It is also optimized for low power consumption and lower BOM cost.

VDSL/VDSL2

The demand for ever faster Internet access to support multiple new applications such as IPTV, VoIP, VoD and video conferencing is increasing rapidly.  VDSL2 (ITU-T G.993.2) uses the existing copper wire infrastructure for transmission of up to 250 Mbps and is now being deployed to subscribers in key regions worldwide to meet bandwidth demand.  With the increased bandwidth, VoIP service will be a common application in VDSL/VDSL2 deployments.  Embedded VoIP software can be used to add VoIP capability to VDSL2 gateways, routers and IADs.

The vPort GW solution is ideal for VDSL2 CPE equipment, providing high voice quality, efficiently tuned system implementation, and broad OS and IC support for platform flexibility. 

FTTH: PON & GPON

The demand for ever faster Internet access to support multiple new applications such as IPTV, VoIP, VoD and video conferencing is increasing rapidly.  PON and GPON (ITU-T G.983 and G.894) high-speed broadband service is now being deployed to subscribers in key regions worldwide to meet bandwidth demand.  With the increased bandwidth, VoIP service will be a common application in FTTH deployment.  Embedded VoIP software can be used to add VoIP capability to GPON gateways, routers and IADs. 

The vPort GW solution is an ideal VoIP solution for PON/GPON CPE equipment, providing high voice quality, efficiently tuned system implementation, and broad OS and IC support for platform flexibility. 

WiMAX Routers

Fixed wireless devices based on the IEEE 802.16 WiMAX standard address last mile connectivity via a high speed wireless conneciton. WiMAX is becoming increasing popular in fulfilling the promise of last-mile connectivity and is gaining strong support from the industry.  It provides a viable alternative to a number of access technologies including DSL–particularly in areas where the infrastructure is not in place. The technology provides a viable approach for broadband connectivity where existing infrastructure is either inadequate or non-existent. Emerging markets may deploy fixed wireless access based on WiMAX to provide high speed connectivity to rural areas where a wired connection would be prohibitively expensive to deploy. WiMAX CPE devices can provide consolidated Internet services including VoIP, with similar bandwidth and quality as wired broadband technologies.

D2’s vPort GW solution is an ideal VoIP solution for WiMAX CPE equipment, providing high voice quality, efficiently tuned system implementation, and broad OS and IC support for platform flexibility.

IP Phone / Speakerphone

IP-PBX adoption has grown to the point where IP-PBXs now out ship traditional PBXs.  The rapid growth is due to reduced cost and increased productivity that IP telephony brings to the enterprise.  As the infrastructure transitions to VoIP-based IP-PBXs, the end points also transition to VoIP. IP phones can provide high quality audio through the use of wideband telephony, presence information, and easy access to many new IP-PBX functions.  IP desk phones and IP speaker phones are becoming standard in business of all sizes.  Early adoption of IP phones in the consumer market is also occurring.  These IP phones need high voice quality, rich VoIP features, and Acoustic Echo Cancellation to provide full-duplex speaker phone functionality.

D2’s vPort IPP is an ideal VoIP solution for IP desk phones and speaker phones.

IP Set-Top-Box (IPSTB)

With the advent of high speed Internet access, comes a plethora of converged services that take advantage of this common infrastructure and available bandwidth. IPSTB is one such device. These devices provide several services to the end user including TV (IPTV), Video on Demand (VoD), Digital Rights Management (DRM), Instant Messaging, and Voice over the Internet.  End users are demanding these services in addition to home networking and advanced multimedia codecs.

D2’s vPort GW is an ideal software platform to enable VoIP capabilities in the IPSTB application.

Cordless Phone

Cordless phones have a long and established usage in many environments including residential and business settings. Recent changes to cordless phone technology and standardization have led to the adoption of Digital Enhanced Cordless Telecommunications (DECT) Standard. DECT based cordless phones minimize the interference with other wireless technologies and can be modified to provide VoIP and VoIM functionality on top of the physical access layer that DECT provides. The base station of a DECT phone can be designed to access the Internet instead of a standard PSTN interface. This enhancement allows cordless phones to leverage their existing rich features and strong acceptance in the consumer environment, and add cost effective VoIP access to further enhance their value. To achieve this, cordless phones need to integrate the VoIP components into the cordless base station and enhance the interface to the handsets to accommodate new features such as presence/contact lists.

D2’s vPort CP is an optimized software solution for VoIP-Based cordless phones.

Analog Telephony Adaptor / VoIP Gateway

The Analog Telephony Adaptors (ATA) is used as the main gateway between the Internet-based VoIP service and standard analog telephones that normally connect to the PSTN line. The ATA allows the existing set of end user telephones, answering machines, and faxes to use VoIP rather than the traditional PSTN. ATAs emulate the PSTN line (FXS) to convert analog telephony signals to VoIP signaling and media streams, so voice call can be transported over the internet.

D2’s vPort GW is an ideal VoIP software solution for stand-alone ATAs or to add ATA functionality to broadband routers and gateways.
