Ditech Networks is the world's voice quality leader. Our solutions are deployed in wireless and VoIP networks to measure, analyze and optimize voice service on each and every call.

As an equipment provider to world's communications industry, we deliver reliable products that are deployed on high-performance platforms that are purpose-built for TDM and IP networks.

These solutions perform critical functions in managing the business of voice. Our Experience Intelligence service has the industry's only technology that measures live subscriber calls to detect voice impairments that originate both inside and outside of the network. Experience Intelligence derives a Mean Opinion Score (MOS) value that reflects the total call experience, not just the effect of network infrastructure on voice quality.

Ditech's Voice Quality Assurance solution solves voice quality problems that occur both inside and outside of the network. These problems, called impairments, are mitigated in real-time for both ends of the call. Ditech is the only company worldwide that can simultaneously mitigate the six most widely occurring impairments on mobile and VoIP calls. Eliminating or reducing these impairments can cost-effectively increase the Mean Opinion Score (MOS) to a level that favorably impacts churn, revenue and customer satisfaction.

For IP networks, Ditech delivers two additional components for the management and deployment of low-cost, high-value voice service: the Peerpoint Session Border Control and Codec Transcoding. Peerpoint's broad interoperability allows deployment in any network without requiring changes to the network or to the VoIP subscribers' equipment configuration. Codec Transcoding supports the industry's widest variety of codecs without compromising call volume.

These solutions are deployed in TDM networks on Ditech's Broadband Voice Processor or Quad Voice Processor platforms, and in IP networks on the Packet Voice Processor™ platform. Each are high-density, high-performance platforms that are widely deployed worldwide.

We deliver the industry's most comprehensive suite of voice quality products and platforms, which gives our customers an unprecedented triple play: voice quality up, network capacity up, and cost down.

Founded in 1983 and listed on the NASDAQ (DITC) since 1999, Ditech has successfully built on its foundation of echo cancellation to become the global leader in voice quality solutions. Headquartered in Mountain View, California, Ditech has been serving the needs of communications service providers for more than 15 years, including industry leaders like Verizon Wireless, Orascom Telecom, Oi Telecom, Sprint/Nextel, AT&T, West/Intecall, Global Crossing and Quest.

Our Commitment To Quality

Ditech Networks' comprehensive approach to quality underscores our dedication to product and service excellence, customer satisfaction and environmental responsibility.

ISO 9001 is the widely accepted standard for quality management. ISO 14001 provides a similar framework for environmental management. Ditech has been ISO 9001 certified since 1997, and 14001 certified since 2004.

We are recognized as having a consistently strong, integrated management system that supports world-class product and process quality, as well as environmentally responsible business practices. Our CY2007 initiatives include reducing paper consumption, and continuing our bi-annual employee e-waste recycling events.

Environmental Management Programs

Ditech formalized its commitment to responsible environmental management with ISO 14001 certification in 2004. The initial programs focused on reducing the use of consumable items and implementing targeted recycling programs. Since then, Ditech has expanded its efforts by establishing:

Proactive Approach to Business Practices

Comprehensive Recycling Programs

Employee e-waste Recycling Events

Partnerships for Environmental Responsibility

Worldwide Environmental Legislation

RoHS originally referred to the European Union (EU) Directive 2002/95/EC on the Restriction of six specific hazardous substances in electrical and electronic equipment. The six restricted substances are: Lead (Pb), Mercury (Hg), Cadmium (Cd), Hexavalent Chromium (Cr-6), and PBBEs, and PBDEs. Since the implementation of the EU directive in 2006, other countries have begun investigating and/or implementing similar legislation.

European Union: Based on independent industry benchmarking and guidance offered by the UK's Department of Trade and Industry, Ditech will use the lead-in-solder exemption allowed for network infrastructure equipment. As such, Ditech products meet what is commonly called 5-of-6 compliance to the EU ROHS directive 95/2002/EC.

China-RoHS: Although similar in scope, implementation of China-RoHS is differs from the EU program. As of March 1, 2007, all Ditech product placed for sale in the China market is in compliance with the key elements of China's Phase 1 program. Among the requirements are: the marking of all product packaging with the appropriate recycling symbol, and the inclusion of a Hazardous Substance Table (HST) identifying the presence of any of the six restricted substances.

WEEE: The EU Waste from Electrical and Electronic Equipment Directive requires producers and importers of electrical and electronic equipment to be responsible for the collection, treatment, and recovery costs of WEEE. Ditech supports EU efforts to reduce waste from electrical and electronic equipment. All Ditech products, placed on the EU market after January 1, 2006 are labeled with the crossed-out wheelie bin symbol.
