increase in revenues of $150 in 2003. In addition, there was a substantial increase in revenues associated with our Internet Protocol, or IP,
telephony solutions as customers continued to migrate towards converged packet voice solutions.
Revenues associated with the data networking and security portion of this segment decreased significantly in 2003 compared to 2002. The
significant decrease in revenues was primarily due to a decline in new service contracts and service contract renewals, a decline in revenues
associated with our legacy routing portfolio and a decline in revenue from certain of our data networking products primarily due to pricing
pressures driven by increased competition. This was partially offset by a net increase in previously deferred revenues associated with certain
data switch upgrades of approximately $60 in 2003.
Enterprise Networks revenues declined sequentially in the first and second quarters of 2003 and increased sequentially in the third and fourth
quarters of 2003. The sequential declines in the first half of 2003 were primarily due to customers having sufficient network capacity,
continued capital spending restrictions by our customers and delays associated with the establishment of new channel relationships to address
demand from small and medium sized enterprise customers. The sequential increases in revenues in the second half of 2003 were primarily due
to a sequential increase in revenues associated with our IP telephony solutions as our customers continued to migrate toward packet voice
solutions as well as revenue recognized due to the release of certain software including Succession 3.0 in the fourth quarter of 2003. Further,
we experienced sequential revenue increases in the third and fourth quarters of 2003 from our interactive voice response and security products
as a result of certain new product releases in the second half of 2003.
From a geographic perspective, the 7% increase in Enterprise Networks revenues in 2003 compared to 2002 was primarily due to a:
The 25% reduction in Enterprise Networks revenues in 2002 compared to 2001 was primarily a result of enterprise customers continuing to
reduce their spending due to the ongoing industry adjustment, the overall economic conditions and uncertainties surrounding the technology
evolution of next generation products.
Revenues from the circuit and packet voice portion of this segment declined substantially in 2002 compared to 2001. The substantial decline
was primarily due to reductions in customer spending in the U.S. and EMEA. Revenues for traditional circuit switching products did begin to
show signs of improvement in the U.S. in the second half of 2002 after experiencing sequential quarterly reductions during 2001 and the first
half of 2002. In 2002, traditional circuit switching also continued its evolution towards IP telephony solutions, as reliability and quality of
service concerns, traditionally associated with voice over packet solutions, were reduced. Regardless, customers remained cautious in 2002
with respect to their investment decisions due to uncertainties surrounding the migration to packet voice solutions.
The data networking and security portion of this segment experienced significant declines in 2002 compared to 2001. The significant decline in
revenues was primarily due to customer spending constraints and a decline in demand for mature products across all regions. Pricing pressures
continued in 2002 in the data networking and security portion of this segment as we experienced continued significant competition for
enterprise customers.
From a geographic perspective, the 25% decline in Enterprise Networks revenues in 2002 compared to 2001 was primarily due to a 28%
decline in the U.S., a 23% decline in EMEA and a 17% decline in Asia Pacific. These declines were all primarily due to the ongoing industry
adjustment, the overall economic conditions and uncertainties surrounding the technology evolution of next generation products.
During 2004, our Enterprise Networks customers have continued to increase the deployment of voice over packet technologies in their
communications networks. We expect that data, voice and multimedia communications will continue to converge, and enterprises will look for
ways to maximize the effectiveness of their existing networks while reducing ongoing

• 14% increase in revenues in the U.S. primarily due to the release of certain software including the general availability of Succession
3.0 in the fourth quarter of 2003 which triggered the recognition of associated revenues deferred from prior periods. In addition,
revenues increased due to the recognition of deferred revenues associated with certain data switch upgrades; partially offset by
• 19% decline in revenues in CALA primarily due to the reduction of inventory by the distribution network in the region and the
unfavorable economic conditions in certain countries.
