NEW YORK -- Verizon (NYSE: VZ) has introduced packet switching to transmit voice phone calls with the successful deployment of Nortel Networks* (NYSE/TSX: NT) packet-switching equipment in large Verizon switching centers in New Jersey and Florida.
The move is part of Verizon's overall effort to deploy the industry's most advanced technology in its nationwide network, continually improving service and positioning the company's network to provide integrated voice and data services.
The deployments -- Verizon's first step toward widespread deployment of packet-switching technology in its voice network -- represent the largest application of packet-switching technology for voice transmission by a local exchange carrier in North America. Thus far, the New Jersey packet-switching deployment has successfully completed over 1.8 million voice phone calls.
The deployments, designed to evaluate the reliability of packet technology, pave the way for the expanded use of packet-switching technology for future voice transmission needs. The technology is designed to provide Verizon with faster call routing, greatly expanded network capacity and the ability to deliver new services, while enabling a seamless transition for Verizon customers.
This use of the packet-switching technology to carry voice calls is known as voice trunking over ATM switches, or VToA. ATM stands for Asynchronous Transfer Mode, a high performance, cell-oriented switching and multiplexing technology, historically used for data applications.
"Packet-switching technology will enable Verizon to provide customers with all the high quality services they have today, and realize efficiencies which do not exist in today's circuit-switching environment," said Phil Harrington, Verizon's VToA program manager. "It is very important to us that this network transition be absolutely seamless to our customers, and that it enable the delivery of mission-critical services with very high reliability. We're also planning to deploy this technology at a number of new locations over the next 18 months."
"With this deployment, Verizon is in an excellent position to efficiently accommodate growth and build the foundation for the delivery of new voice, data and video services in the future," said Sue Spradley, president, voice over Internet Protocol (VoIP) for Nortel Networks. "Nortel Networks is in a unique position to effectively enable this migration because of our detailed understanding of network design and service delivery, our solid circuit-to-packet migration strategy, and our comprehensive voice over IP portfolio."
Packet switching permits groups of messages -- voice or data -- from many different sources to share the same communications line, resulting in more efficient use of existing transmission capacity and lines. This provides a significant advantage over circuit switching --the technology used in telecommunications networks today -- which uses communications lines that are dedicated to the same source and destination. Another advantage of packet switching over circuit switching is that it more readily lends itself to a distributed network, which is a more survivable network infrastructure in the event of damage to the network.
During the initial Verizon VToA deployment, voice calls are being transmitted through major regional call- and data-switching centers known as tandems. The two Verizon tandems are located in Newark, N.J., and Tampa, Fla.
The two switching centers used products from Nortel Networks VoIP portfolio including the Succession* Communication Server 2000 softswitches, Succession Multi-service Gateway 4000 and Passport* 15000 Multiservice Switches for ATM transport.
VToA technology also offers the potential for a cost-effective way to migrate to a Voice over IP platform, if the market and future technology justify that move at some time in the future.
