DITC - This is the only news I saw from 2 days ago. Watchlist #10 from 8/26 seeing lots of $ flowing in. Ditech Communications Announces Far End Echo Cancellation (FEEC) for Satellite Communications PR Newswire, Tuesday, August 24, 1999 at 09:19 FEEC Allows Satellite and International Long Distance Service Providers To Guarantee Quality Voice Service on a Worldwide Basis MOUNTAIN VIEW, Calif., Aug. 24 /PRNewswire/ -- Ditech Communications Corporation (NASDAQ:DITC) today announced its Far End Echo Cancellation (FEEC) technology which allows satellite and international long distance telephone service providers to guarantee quality voice calls on a worldwide basis. International long distance service providers use satellite communications systems to provide global coverage to cellular users as well as basic call routing to developing countries where no telephone infrastructure exists. The long transmission distances involved in satellite communications introduce severe echo problems into voice calls. This has typically forced service providers to go through the substantial time and expense of deploying echo cancellers in land-based relay stations in the countries where the calls are initiated or received. Ditech's FEEC allows satellite and international service providers to deploy very powerful echo cancellation in their major relay stations located in the United States and Europe, eliminating the time and expense of deploying echo cancellers in remote areas of the globe. All Ditech Quad E1 echo cancellers shipped after October 1st will incorporate this new FEEC capability without any additional cost added to the Quad E1 product (E1 is the international standard for voice communication). Customers who have already purchased Quad E1s can download the FEEC upgrade software from Ditech's web site at no charge. "The demand for far-end echo cancellation is based on a number of converging factors," said Tim Montgomery, Ditech's President and CEO. "First, in an increasingly global economy, people everywhere are demanding ubiquitous, worldwide communication service. In the telecommunications industry, deregulation has spurred an intensely competitive race to deliver global phone service. To win this race, service providers must be quick to market with high quality voice service. Far-end echo cancellation -- or FEEC -- is an important asset in this race." Continued Montgomery, "For example, a U.S. satellite provider wanting to offer voice service to Indonesia, the world's fourth most populous country, could deploy our FEEC-enabled echo cancellers in their major relay station in Los Angeles. With the capability to cancel echoes transmitted over lengthy satellite hops, our FEEC echo cancellers in Los Angeles would cancel any echoes generated in Indonesia, thereby eliminating the time-to-market issues and the expense of installing echo cancellation equipment in Indonesia. In summary, FEEC improves voice quality over very long satellite circuits without having to invest in equipment at the far-end of the circuit." FEEC Boosts Canceller's Delay-Handling Five Fold In a telephone call, any transmission delay beyond 20 milliseconds (ms) exacerbates the echo problem present in all telephone calls. While a typical echo canceller can only handle transmission delays of up to 128 ms, Ditech's FEEC increases Ditech's echo canceller's delay-handling capability by nearly five fold, allowing service providers to handle transmission delays of up 624 ms. Ditech Communications Corporation Ditech Communications Corporation designs, develops and markets equipment used in building and expanding telecommunications and cable communications networks. Ditech's products fall into two categories, echo cancellation equipment and optical communications subsystems. Ditech's echo cancellers utilize Ditech's advanced digital signal processing and integrated circuit technology to deliver one of the industry's most advanced voice quality of service (Ditech's VQoS(TM)). Ditech's optical communications products include optical amplifiers, DWDM multiplexers, transponders, and optical telemetry and monitoring systems. Ditech's customers include local and long distance carriers, wireless and Internet telephony providers worldwide.
