Cignal announces ATM counter salvo to VoIP with patented techniques, and will integrate Voice over packet, as well, they say. ---------------- "Historic Voice-Over-Data-Network Patent Awarded to Cignal Global Communications Technology To Support Cignal's Toll-Quality Voice Over ATM Network" May 27, 1998 CAMBRIDGE, Mass.--(BUSINESS WIRE) via NewsEdge Corporation -- The U.S. Patent Office has issued patent number 5751706 to Cignal Global Communications for its voice over packet-switched network technology. The patented technology, called SM-10 (Switched Multimedia Transmission Over an Efficient Network) is at the core of Cignal's plans to roll out a global ATM network that supports aggressively priced voice and data services to carriers, Internet Service Providers (ISPs), and businesses. The telecommunications industry has been spending millions of dollars to develop and deploy technologies that use the Internet and other data networks to deliver telephone calls. This patent affirms Cignal's leading edge technology for delivering toll-quality telephone services over managed packet-switched networks. "When Mark Land and I set out two years ago to build a next-generation international telecommunications company, we knew that packet-networking technologies had to be at the core of our success. This patent gives us a huge advantage over the competition and sets the stage for fundamental changes in the economics of telecommunications networks," said Andrew Perlman, President and co-founder of Cignal. Cignal's SM-10 technology involves the transmission of telephone calls over long-haul cell and packet-based networks that connect with the local telephone networks at each end. It includes, among other things, the integration of telephone features such as answer supervision (a signaling system that ensures accurate billing), SS7/C7 signaling for interconnection with local and long distance carriers, CLI call screening for customer identification and security, dynamic volume control, and echo cancellation. In addition, Cignal's latency, the one-way delay between hubs, is at 200 milliseconds (ms) and well below the threshold of noticeable delay at 250 ms. "The features that are built into SM-10 are used throughout the world's existing telephone networks, but are absent from most other voice over packet network solutions such as Internet Telephony," said Bryan Van Dussen, Vice President of Business Development and Marketing. "With these features, Cignal is building a carrier-class network capable of delivering tens of millions of minutes of high-quality, aggressively-priced long distance services per month." Cignal's beta network is operational between Boston and London and will be extended to New York City, Hong Kong and San Francisco by July 1998. Cignal's mission is to capitalize on additional international markets as they open up to competition. By year end 1999, Cignal will have 30 Point of Presence (POPs) in Asia, Europe, and the Americas. Cignal Global Communications Inc., Cambridge, Massachusetts, is a global facilities-based telecommunications carrier that is deploying a global ATM network to deliver simple and easy to use international voice and data services to carriers, ISPs, and businesses. Operating its own global multimedia ATM network, Cignal maintains facilities in Boston, New York, Hong Kong, London and San Francisco.

>>xDSL is an access technology.<< Very true Frank. Not many people realize that. I've met people that think ADSL is a WAN technology, like frame relay. Cisco is just capitalizing on the end-to-end buzzword that is so popular in telecom circles. My definition of an end to end ADSL service is an ATU-R terminating into an ATU-C. Alternately, an end to end high speed architecture can employ ADSL as a means to boost local loop speeds. Hal
