EDEVICE ANNOUNCES INDUSTRY'S FIRST VOICE-ENABLED INTERNET MODEM FOR PSTN VOIP PHONES.eDevice (www.eDevice.com), a leader in embedded technology for connecting non-PC equipment and appliances to the Internet, has announced SmartStack VoIP, the industry's first voice- enabled Internet modem for PSTN (Public Switched Telephone Network) The worldwide voice telephone network. Once only an analog system, the heart of most telephone networks today is all digital. In the U.S. Internet telephones. eDevice is offering the industry's only embedded software Instructions that permanently reside in a ROM or flash memory chip. Embedded software may be immediately available to the CPU or, for faster execution, may be transferred to RAM first and then executed. that integrates all of the software building blocks needed for full VoIP capability on a single, standard, off-the-shelf DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive . SmartStack VoIP is the first client application to be offered by eDevice to accompany its SmartStack Internet-enabling software. This new VoIP capability can be used in VoIP phones, not only in a LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. network, but can also be used in such PSTN applications as public and home phones, security systems, and other user defined Any format, layout, structure or language that is developed by the user. client applications. SmartStack VoIP includes the speech codec to manage the voice compression and decompression, the Internet protocols stack, and the physical layer software (soft modem for PSTN or soft MAC for Ethernet LANs). The product is a complete signal-processing device, handling the voice signal from the handset output to the PSTN or Ethernet connector making it a very cost- and space-efficient solution for VoIP telephones and future applications. "Corporations can better take advantage of the Internet and realize substantial savings by routing voice telephony over the Internet and company-wide intranets," explained Marc Berrebi, CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of eDevice. "To make this a reality, OEMs need to provide small and inexpensive VoIP-enabled phones. SmartStack VoIP is a turnkey VoIP voice-enabled Internet modem on a single chip, which enables telephony OEMs to quickly and cheaply integrate VoIP into telephone handsets or any other telephony device. The savings generated using VoIP in Ethernet and PSTN applications can send greater savings along to the consumer." SmartStack VoIP is an off-the-shelf DSP-based voice-enabled Internet modem that enables OEMs to easily integrate the most cost-effective and smallest footprint hardware required to add Internet connectivity into their equipment. SmartStack VoIP opens the door to an entire new range of future applications bringing VoIP to such devices as security systems or emergency alert systems for public spaces. It also provides complete Internet functionality (email, FTP FTP in full file transfer protocol Internet protocol that allows a computer to send files to or receive files from another computer. Like many Internet resources, FTP works by means of a client-server architecture; the user runs client software to connect to , and Web server) without the need for a PC or special ISP (1) See in-system programmable. (2) (Internet Service Provider) An organization that provides access to the Internet. Connection to the user is provided via dial-up, ISDN, cable, DSL and T1/T3 lines. . As an embedded software voice-enabled Internet modem running on a single Analog Devices' DSP, SmartStack VoIP is completely integrated with the physical layer software (a PSTN modem or an Ethernet MAC) to provide Internet connectivity over the public telephone network or any local area network (LAN). It requires no extra gateways and no customer code. The system is entirely flexible; the protocols are not proprietary. The only other requirements for SmartStack VoIP are a standard flash memory, the physical line interface (DAA DAA - Distributed Application Architecture: under design by Hewlett-Packard and Sun. A distributed object management environment that will allow applications to be developed independent of operating system, network or windowing system. or PHY See physical layer and physical. ), and a vocoder (VOice CODER) Same as speech codec. (communications) vocoder - Hardware or software which implements a compression algorithm particular to voice. . Developers can currently opt for a SmartStack software license to simply integrate the technology into their own hardware solution. A turnkey chipset will also be available as a socket-like modem, SmartStack Modem, or as a complete chipset with serial port and line jack, SmartStack Box. SmartStack products easily interface with other applications via a simple, AT-like command set running on the DSP. VoIP represents a high-growth market in the near term, as companies look to cut costs and leverage existing network infrastructures. "VoIP will be an important aspect of the communications landscape," says John Williams of Harbor Research. "VoIP's rapid growth will only continue as companies realize the benefits of paying for one IP-based communications environment instead of having separate voice, data and automation networks. As non-PC devices become network enabled, companies will want these devices to interact seamlessly through a common IP networking environment and eDevice's SmartStack for VoIP will be a major enabler towards this end." |
