Ditech Communications Chooses Telchemy for Integrated IP Performance Monitoring; Integrates VQmon/EP Into Packet Voice Processor to Enable Deployment of Scaleable, Carrier-Grade VoIP Services.SAN JOSE, Calif. -- At Spring VON 2006, Telchemy,(R) Incorporated, the global leader in VoIP fault and performance management technology, announced that Ditech Communications Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :DITC DITC Diggin' in the Crates (rap group) DITC Ditech Communications Corporation (stock symbol) DITC DeKalb International Training Center DITC Design in the Classroom DITC Deception in the Church ), has integrated VQmon/EP(TM) VoIP performance monitoring technology into its Packet Voice Processor(TM) voice processing platform. VQmon/EP will help Ditech Communications enable carriers to deploy scaleable, carrier-grade VoIP services. Ditech Communications will incorporate Telchemy's market leading VoIP call quality monitoring technology to offer carriers robust real-time monitoring and voice quality measurement of voice channels across the network. With Telchemy's technology, Packet Voice Processor will enable carriers to ensure total voice quality, recognize and identify network related call quality problems, and provide advanced reporting for network planning and customer SLAs. VQmon/EP detects packet loss and jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle buffer discard events, utilizes key speech information from 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 software and produces call quality scores and diagnostic data. VQmon is based on the 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. E Model with many extensions to improve accuracy under time varying network conditions, wideband codecs, orthogonal impairments and signal related parameters. Network operators and system administrators use Telchemy's VQmon technology to detect, monitor and resolve call quality and network related problems for networked multi-media services, including Voice and Video over IP and to support active QoS control applications such as call admission control. "Telchemy's VQmon enables us to deliver an unprecedented voice quality management capability on our Packet Voice Processor," said Dr. Chalan Aras, Vice President of Marketing at Ditech Communications. "VQmon's ability to go beyond packet statistics to integrate actual speech measurements into the ITU E Model to estimate a more accurate voice quality measurement will enable service providers using the Packet Voice Processor to truly understand the subscriber experience and deliver the best VoIP service." Designed to address the voice quality and interoperability problems of the VoIP network, Ditech's Packet Voice Processor is integrated with a comprehensive set of voice processing features that ensure consistently good voice quality while maximizing carrier service offerings. Ditech's codec transcoding feature provides support for a broad class of voice codec transcoding, while unique voice quality enhancement capabilities ensure high quality VoIP service delivery with best-in-class scalability and density. The advanced voice processing architecture of the Packet Voice Processor supports nearly 50,000 transcoding sessions per rack with very low delay. "Telchemy and Ditech both share a strong commitment to delivering the highest quality VoIP calls," said Alan Clark, 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 Telchemy, Incorporated. "Integrating VQmon/EP into Ditech's voice processing platform helps it meet the high expectations of its carrier customers." VQmon generates listening and conversational quality MOS (1) (Metal Oxide Semiconductor) See MOSFET. (2) (Mean Opinion Score) The quality of a digitized voice line. It is a subjective measurement that is derived entirely by people listening to the calls and scoring the results from scores and R factors and a wide range of diagnostic data, making these available through an API as raw metrics, RTCP XR and SIP QoS Report payloads. VQmon is the first VoIP Performance Management software to support the new VoIP management protocols, providing the essential metrics for the International Engineering Task Force (IETF See Internet Engineering Task Force. IETF - Internet Engineering Task Force ) RFC (Request For Comments) A document that describes the specifications for a recommended technology. Although the word "request" is in the title, if the specification is ratified, it becomes a standards document. 3611 (RTCP XR) media path reporting protocol and QoS reporting protocols for SIP, H.323, MGCP See MGCP/MEGACO.
