Mobility, Flexibility in Communications Driving Enterprise Convergence - Survey; Nortel Survey Indicates 85 Percent Now on Path to IP Telephony

Business Editors/High-Tech Writers

ORLANDO, Fla.--(BUSINESS WIRE)--June 6, 2005--Mobility and flexibility in communications are driving the increasing enterprise convergence of multiple voice and data networks into one based on new Internet Protocol (IP) technologies, according to a Nortel (NYSE:NT) (TSX:NT) survey of 300 members of the International Nortel Networks User Association (INNUA).

The survey, analyzed by Webtorials, indicated that 85 percent of respondents have already started to converge or have plans to converge voice and data networks within the next five years, while 46 percent have fully deployed or are in the process of deploying a converged network.

This is a six percent increase over the 79 percent of respondents in last year's survey.

As well, 64 percent of survey respondents indicated that the greatest benefits of convergence are mobility and flexibility for employees

"Nortel's survey suggests that enterprises recognize the value of business benefits possible through deploying mobility solutions for anywhere, anytime access to communication services," said Malcolm Collins, president, Enterprise Networks, Nortel

"Mobility powers creativity and productivity in a wide variety of ways, such as providing opportunities for employees to sharpen skills through distance learning programs or allowing employees to work from remote locations, staying connected with customers, partners and suppliers, which may help improve profitability," Collins said

"The continued move to a converged voice, data and video network mirrors what we're seeing in the industry as a whole," said Steve Taylor, president, Webtorials.

"It's also noteworthy that the percentage of respondents that don't have any plans to converge dropped by about a quarter - from 21 percent a year ago to only 15 percent this year." Additional benefits of convergence confirmed by survey respondents include the ability to deploy new multimedia applications and the reduction of network costs.

According to respondents, critical value-added applications that are deployed or will be deployed include unified messaging, multimedia collaboration, video communication and contact centers

The survey also asked if convergence requires changes in the management structure and whether respondents are going to deploy wireless local area networks (LANs).

A majority of the respondents (74 percent) plan to have a combination of telecommunications and data networking staff primarily responsible for management of the converged network.

The survey also showed that a majority of respondents currently use or are planning to deploy wireless LANs (72 percent)

This represents a seven percent increase over 2004, while the planned use of voice over wireless LAN doubled from last year

To meet the needs of its customers, Nortel has designed more reliable, secure solutions such as 'Office Anywhere' mobility.

These solutions build on the strong foundation of the Virtual Enterprise, designed to allow dispersed employees to collaborate as effectively as if they were in the same office, regardless of physical location

These solutions further the graceful mobility evolution demonstrated by other mobility announcements with Research In Motion and on Nortel's broadened WLAN 2300 portfolio for enterprises of all sizes
