GDC Awarded Voice Compression Product of the Year; CTI Confirms GDC's Forward-Thinking Voice Technology.MIDDLEBURY, Conn.--(BUSINESS WIRE)--March 15, 1999-- Industry-leading GDC GDC Game Developers Conference GDC General Dental Council GDC Gouvernement du Canada GDC Georgia Department of Corrections GDC Global Data Center GDC Guglielmi Detachable Coil GDC Global Development Center GDC Institute for Genetic Disease Control in Animals APEX(R) Voice Service Module (VSM VSM Value Stream Mapping (manufacturing process evaluation technique) VSM Vibrating Sample Magnetometer VSM Vascular Smooth Muscle VSM Visual Studio Magazine VSM Vietnam Service Medal VSM Virtual Shared Memory VSM Viable Systems Model ) has been named "1998 Product of the Year" for voice compression by CTI (Computer Telephone Integration) Combining data with voice systems in order to enhance telephone services. For example, automatic number identification (ANI) allows a caller's records to be retrieved from the database while the call is routed to the appropriate party. Magazine. The awards are dedicated to honoring only the industry's most deserving products and vendors. "We are pleased CTI acknowledges the technical advantages of our GDC APEX Voice Service Module," said Keith Mumford, vice president and general manager, General DataComm's Broadband Division. "We anticipate substantial growth for voice-over-ATM customer applications worldwide as the rate of voice/data convergence in both private and public network architectures accelerates." The VSM module is one component in the GDC APEX multiservice architecture, which enables customers to provision services such as, frame relay, 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. interconnect, video and voice over a single platform. VSM enables startup alternate service providers who are marketing calling-card, long distance, international and business-to-business voice services to bill more minutes over existing bandwidth, increasing revenues while avoiding additional cost. Enterprise customers use VSM to consolidate high-quality, low-delay voice calls over private or public ATM Wide Area Networks, which additionally carry their IP Intranet traffic between sites. "CTI magazine prides itself on having the most in-depth and objective product reviews of any telecom or datacom publication," said Rich Tehrani, group publisher, CTI Magazine. "General DataComm's GDC APEX Voice Service Module distinguishes itself as one of the most forward thinking and useful products announced in the field of voice/data convergence - a field that is abundant with new products." GDC's VSM delivers on the original economic promise of variable rate voice-over-ATM by providing 32K ADPCM (Adaptive Differential PCM) A widely used variation of PCM that codes the difference between sample points like differential PCM (DPCM), but can also dynamically switch the coding scale to compensate for variations in amplitude and frequency. and 8K 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 voice compression, silence suppression and echo cancellation. It is the first commercially available product to demonstrate the ability to multiplex and transmit voice calls according to the International Telecommunications Union's (ITU (International Telecommunication Union, Geneva, Switzerland, www.itu.ch) A telecommunications standards body that is under the auspices of the United Nations. Comprising more than 185 member countries, the ITU sets standards for global telecom networks. ) AAL (ATM Adaption Layer) The part of the ATM protocol that breaks up application packets into 48-byte payloads which become ATM cells when the 5-byte headers are attached. The AAL resides between the higher layer transport protocols and the ATM layer. 2 recommendation for the adaptation of voice-over-ATM. It is the only voice-over-ATM solution to offer both standards-based variable-bit-rate (rtVBR/AAL2) and constant-bit-rate (CBR/AAL1) capabilities in a single hardware platform.
