Nortel Networks* [NYSE/TSE: NT] today announced a new carrier-grade Packet Data Serving Node (PDSN) platform to help bridge the gap between wireline and wireless and allow wireless operators to deliver content-rich IP capabilities and services more cost effectively.
Demonstrated at the 2000 CDMA World Congress in Hong Kong this week, the PDSN is a packet data gateway for Nortel Networks' cdma2000* 1XRTT wireless architecture. The PDSN is built on Nortel Networks' industry leading Shasta*
5000 Broadband Service Node and provides operators with seamless migration
to high-speed Wireless Internet services and applications.
The PDSN delivers IP services, subscriber scalability and ubiquitous support for any cdma2000 network. It lowers operator costs by enabling them to support one common PDSN platform throughout their network, and by reducing
sparing requirements, training costs and overall operational expenses. The PDSN is a highly redundant and scalable platform that uses a distinct subscriber management system to help operators manage rapid subscriber
"We are a global leader in bringing IP capabilities to Wireless networks,"
said Alastair Westgarth vice-president, Wireless Internet, Nortel Networks. "The PDSN is a scalable, robust platform that provides carrier grade multimedia packet solutions and eases the transition to next generation mobile IP applications."
"Our ultimate goal is to lower operating costs for carriers, and to help them deliver revenue generating, content rich applications and services to subscribers at web speed," Westgarth said.
A number of key global operators in the United States, Canada, South America, Australia and Asia are conducting cdma2000 1XRTT trials using the
Nortel Networks' PDSN solution.
Nortel Networks uses a standard radio-to-packet network interface on the PDSN to enable interoperability with cdma 2000 1XRTT radio equipment from other manufacturers. The PDSN provides access to multiple IP services, such
as Internet access, firewalls, virtual private networks, traffic engineering and captive portals.
The Nortel Networks' Shasta 5000 Broadband Service Node is uniquely positioned in the wireless network space as the bridge to the IP network. The Shasta 5000 enables carriers, competitive local exchange carriers
(CLECs) and Internet Service Providers (ISPs) to increase their competitive advantage by transitioning from the simple connectivity model enabled by first generation subscriber management systems to a profitable, network-based, value-added services model. cdma2000 1XRTT digital radio technology is expected to support data
transmission speeds up to 144 kilobits per second (kbps) or 10 times the speed commonly available today. cdma2000 3XRTT should ultimately offer
speeds up to 384 kbps for mobile and two megabits per second for stationary applications.
