AudioCodes Reveals Internet Telephony Breakthrough; Industry's First H.323 Multi-Channel Voice Processor Enables Low-Cost Internet Telephony Gateways and WAN Voice Routers.CUPERTINO, Calif.--(BUSINESS WIRE)--Dec. 9, 1996--Leading the rush to deliver high-quality, low-cost Internet voice capabilities, AudioCodes Ltd. today announced the QuadVoIP, the first multi-channel voice communications processor for carrying voice and fax over the Internet and other Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. (IP) networks. Based on the ITU-H.323 visual telephony standard, the QuadVoIP chipset's unprecedented price/performance ratio In economics and engineering, the price/performance ratio refers to a product's ability to deliver performance, of any sort, for its price. For instance, if you have a whole day to travel 100 km, spending $50 to do the journey in two hours is a better price/performance ratio than will help boost the emerging voice-over-network (VON) market by driving down the cost of Internet telephony Another term for IP telephony and VoIP. In the late 1990s, some people made a distinction between Internet Telephony and VoIP: Internet telephony referred to voice over the public Internet, while VoIP referred to voice over private IP networks. gateways and multiprotocol WAN routers. Internet telephony gateways and WAN voice routers make it possible to communicate by voice or fax anywhere in the world for the cost of a local call by transporting these calls over IP networks, such as the Internet or private intranets, instead of traditional telco voice lines. The cost savings in manufacturing these devices made possible by the QuadVoIP, AudioCodes believes, will significantly accelerate the widespread adoption of this alternative long-distance telephony technology. "Until now, one 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 chip was required to support each voice channel in an Internet gateway (1) See cable/DSL gateway. (2) A router or server that converts IP packets to IPX, AppleTalk or some other non-IP format and vice versa. It is used to connect non-IP networks to the Internet. or multiprotocol router," said Shabtai Adlersberg, president and 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 AudioCodes. "As a result of the tremendous cost savings made possible by the QuadVoIP, we expect to see a significant boost in the development and sales of voice over network devices supporting Internet telephony gateway and voice over WAN applications." The highly integrated four-channel design of the QuadVoIP chipset offers substantial reductions in price, board space and power consumption for manufacturers of Internet telephony gateways and voice-capable WAN routers. A PC board equipped with six QuadVoIP processors, for example, can handle all the traffic on a full T1 (24 channels). In addition to enabling long distance voice or fax calls to be routed over an IP network such as Internet or intranets, Internet gateways and WAN voice routers allow users on LANS LANS Local Area Network Server (Cisco) LANS Landelijk Actieplatform voor Nationalistische Studenten LANS Leadership Alliance National Symposium LANS Los Angeles AFB Network Support (DOD) with voice over IP to connect directly to the telco network and vice versa VICE VERSA. On the contrary; on opposite sides. . Gateways may connect directly to the telco network using telephony protocols or may connect PBXs to private networks via wide area network routers. The AudioCodes QuadVoIP voice processor employs the H.323/G.723.1 MP-MLQ/ACELP and G.729 annex A CS-ACELP CS-ACELP Conjugate Structure Algebraic Code-Excited Linear Prediction (voice compression, ITU-T Specification G.729 and G.729a) CS-ACELP Conjugate-Structured Algebraic Code-Excited Linear Prediction standards for low bit rate voice compression. AudioCodes originated the G.723.1/MP-MLQ technology, a key part of the standard, and was a major contributor to its development. The H.323 standard allows cross-platform, interoperable voice, data and video communication to occur over data networks such as the Internet or enterprise intranets. In March 1996, Intel and Microsoft, along with over a 120 hardware, software and service companies endorsed the use of H.323 for voice over IP-based networks. The versatile QuadVoIP chipset can be configured to support either G.723.1, G.729A, or both, in both standard and non-standard bit rates. Having a choice of several bit rates that can be switched seamlessly during a conversation facilitates adaptation to varying network load and congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. conditions. Future QuadVoIP releases will include a high quality Internet voice coder specifically designed to withstand high packet loss rate. The QuadVoIP can be easily adapted to changing market conditions by simply downloading a new software version that supports additional voice compression algorithms. AudioCodes is a member of the recently founded VoIP Forum, and is committed to upgrade the QuadVoIP to comply with the emerging VoIP Implementation Agreement as it develops. Availability Prototype devices allowing performance evaluation Performance evaluation The assessment of a manager's results, which involves, first, determining whether the money manager added value by outperforming the established benchmark (performance measurement) and, second, determining how the money manager achieved the calculated return and hardware design will be available in February 1997, and samples supporting fax transmission are scheduled for May 1997. AudioCodes also offers an exceptionally efficient implementation of G.723.1 MP-MLQ MP-MLQ Multi-Pulse - Maximum Likelihood Quantizer on a Pentium processor. This plug-in has already been licensed to a leading Internet multimedia communication provider. About AudioCodes AudioCodes Ltd., a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. established in 1993 in Tel Aviv, Israel, is a fabless semiconductor manufacturer of voice networking devices for wide area networks (frame relay, ATM, IP) and the wireless local loop market.
