For a monthly fee, ISPs provide computer users with a connection to their site (see data transmission), as well as a log-in name and password. (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 See telecom 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.

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 Another term for IP telephony and VoIP. In the late 1990s, some people made a distinction between Internet Telephony and VoIP: Internet telephony referred to voice over the public Internet, while VoIP referred to voice over private IP networks. ," 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 New York City: see New York, city. New York City City (pop., 2000: 8,008,278), southeastern New York, at the mouth of the Hudson River.
