Nortel Optical Solution Powers ntl Telewest Triple-Play Services

London, November 13 (ots/PRNewswire) -

- Nortel Optical Technology Forms Backbone of UK Network Enabling
Simpler Delivery of Triple-Play of TV, Voice and Broadband

ntl Telewest, the UK's largest cable operator and a leading
provider of broadband, digital television and telephony, is using a
Nortel(1) [NYSE/TSX: NT] optical solution to deliver its triple-play
of voice, video and data services to residential and enterprise
customers in the UK. The Nortel optical solution significantly
increases the capability and capacity of ntl Telewest's UK backbone
network and helps support the company's newly launched quad-play
services including digital TV with video on demand, unlimited
broadband, home telephone and mobile services.

Nortel is supplying, deploying and supporting the ntl Telewest
enhanced optical network solution which includes next-generation
Dense Wavelength Division Multiplexing (DWDM) as a way of maximising
the capacity of the optical platform and Nortel Global Services for
managing current network traffic and helping deliver additional
network capacity for quad-play services.

"Bringing together multiple services - including TV, broadband and
fixed-line services - gives our customers unbeatable value and puts
them at the forefront of the digital revolution that is transforming
entertainment and communications," said ntl Telewest CTO Howard
Watson. "Our network backbone has to support our service offers by
keeping pace technologically and being cost-effective, flexible,
reliable and easy to operate. We selected Nortel for its advanced
next-generation optical technology and experience in building and
operating networks of this scale. We are developing a highly agile
and flexible network that can evolve efficiently and cost-effectively
as our business grows."

"Critical to Nortel's success in building high-performance all
optical networks is a continuing commitment to innovation and making
complex deployments simple for our customers," said Philippe Morin,
president Metro Ethernet Networks, Nortel. "Nortel's intelligent
optical platforms help enable dynamic communications companies such
as ntl Telewest to increase their bandwidth capabilities flexibly and
efficiently, thereby enabling them to compete in the next wave of
converged mobility and entertainment services."

The next generation DWDM solution for ntl Telewest will leverage
its existing Nortel-supplied WDM and SDH networks and management
systems. The new solution comprises the Nortel Common Photonic Layer
(CPL) and Optical Multiservice Edge (OME) 6500 convergence platform
enabling circuit to packet migration. Together, they will simplify
aggregation and transit nodes while expanding capacity over an
adaptive, intelligent and efficient optical layer. The net result is
a smooth migration to a reliable and scalable Ethernet infrastructure
while maintaining minimal infrastructure costs. Nortel's unique
innovation, WDM transponders with electronic dynamically compensating
optics (eDCO) is key to providing network flexibility,
cost-efficiency and agility.

As part of the ntl Telewest network solution Nortel's Global
Services is delivering full network integration services including
network staging, engineering, implementation and stability testing.
This will give ntl Telewest the ability to upgrade its UK network
without impacting customer service.

Nortel's Global Services include a full range of integrated
services for design, deployment, management and maintenance of
end-to-end multi-vendor network solutions, including seamless
migration to next generation technologies.

Certain statements in this press release may contain words such as
"could", "expects", "may", "anticipates", "believes", "intends",
"estimates", "targets", "envisions", "seeks" and other similar
language and are considered forward-looking statements or information
under applicable securities legislation. These statements are based
on Nortel's current expectations, estimates, forecasts and
projections about the operating environment, economies and markets in
which Nortel operates. These statements are subject to important
assumptions, risks and uncertainties, which are difficult to predict
and the actual outcome may be materially different. Nortel has made
various assumptions in the preparation of its financial outlook in
this press release, including the following company specific
assumptions: no further negative impact to Nortel's results of
operations, financial condition and liquidity arising from Nortel's
restatements of its financial results; Nortel's prices increasing at
or above the rate of price increases for similar products in
geographic regions in which Nortel sells its products; increase in
sales to Nortel's enterprise customers and wireless service provider
customers in the Asia Pacific region as a result of Nortel's joint
venture with LG Electronics Inc.; anticipated growth in sales to
enterprise customers, including the full year impact to Nortel's
revenues from its acquisition of PEC Solutions, Inc., (now Nortel
Government Solutions Incorporated); improvement in Nortel's product
costs due to favorable supplier pricing substantially offset by
higher costs associated with initial customer deployments in emerging
markets; cost reductions resulting from the completion of Nortel's
significant financial restatements and 2004 restructuring plan; a
moderate increase in costs over 2005 related to investments in the
finance organization and remedial measures related to Nortel's
material weaknesses in internal controls; increased employee costs
relative to expected cost of living adjustments and employee bonuses
offset by a significant reduction in executive recruitment and
severance costs incurred in 2005; and the effective execution of
Nortel's strategy. Nortel has also made certain macroeconomic and
general industry assumptions in the preparation of its financial
guidance including: a modest growth rate in the gross domestic
product of global economies in the range of 3.9% which is higher than
the growth rate in 2005; global service provider capital expenditures
in 2006 reflecting mid to high single digit growth as compared to low
double digit growth in 2005; a general increase in demand for
broadband access, data traffic and wireless infrastructure and
services in emerging markets with the rate of growth in developed
markets beginning to slow; and a moderate impact as a result of
expected industry consolidation among service providers in various
geographic regions, particularly in North America and EMEA. The above
assumptions, although considered reasonable by Nortel at the date of
this press release, may prove to be inaccurate and consequently
Nortel's actual results could differ materially from its expectations
set out in this press release.

Further, actual results or events could differ materially from
those contemplated in forward-looking statements as a result of the
following (i) risks and uncertainties relating to Nortel's

restatement and two previous restatements of its financial statements
and related events; the negative impact on Nortel and NNL of their
most recent restatement and delay in filing their financial
statements and related periodic reports; legal judgments, fines,
penalties or settlements, or any substantial regulatory fines or
other penalties or sanctions, related to the ongoing regulatory and
criminal investigations of Nortel in the U.S. and Canada; any
significant pending civil litigation actions not encompassed by
Nortel's proposed class action settlement; any substantial cash
payment and/or significant dilution of Nortel's existing equity
positions resulting from the approval of its proposed class action
settlement; any unsuccessful remediation of Nortel's material
weaknesses in internal control over financial reporting resulting in
an inability to report Nortel's results of operations and financial
condition accurately and in a timely manner; the time required to
implement Nortel's remedial measures; Nortel's inability to access,
in its current form, its shelf registration filed with the United
States Securities and Exchange Commission (SEC), and Nortel's below
investment grade credit rating and any further adverse effect on its
credit rating due to Nortel's restatements of its financial
statements; any adverse affect on Nortel's business and market price
of its publicly traded securities arising from continuing negative
publicity related to Nortel's restatements; Nortel's potential
inability to attract or retain the personnel necessary to achieve its
business objectives; any breach by Nortel of the continued listing
requirements of the NYSE or TSX causing the NYSE and/or the TSX to
commence suspension or delisting procedures; (ii) risks and
uncertainties relating to Nortel's business including: yearly and
quarterly fluctuations of Nortel's operating results; reduced demand
and pricing pressures for its products due to global economic
conditions, significant competition, competitive pricing practice,
cautious capital spending by customers, increased industry
consolidation, rapidly changing technologies, evolving industry
standards, frequent new product introductions and short product life
cycles, and other trends and industry characteristics affecting the
telecommunications industry; the sufficiency of recently announced
restructuring actions, including the potential for higher actual
costs to be incurred in connection with these restructuring actions
compared to the estimated costs of such actions and the ability to
achieve the targeted cost savings and reductions of Nortel's unfunded
pension liability deficit; any material and adverse affects on
Nortel's performance if its expectations regarding market demand for
particular products prove to be wrong or because of certain barriers
in its efforts to expand internationally; any reduction in Nortel's
operating results and any related volatility in the market price of
its publicly traded securities arising from any decline in its gross
margin, or fluctuations in foreign currency exchange rates; any
negative developments associated with Nortel's supply contract and
contract manufacturing agreements including as a result of using a
sole supplier for key optical networking solutions components, and
any defects or errors in Nortel's current or planned products; any
negative impact to Nortel of its failure to achieve its business
transformation objectives, including completion of the sale of its
UMTS access business to Alcatel; additional valuation allowances for
all or a portion of its deferred tax assets; Nortel's failure to
protect its intellectual property rights, or any adverse judgments or
settlements arising out of disputes regarding intellectual property;
changes in regulation of the Internet and/or other aspects of the
industry; Nortel's failure to successfully operate or integrate its
strategic acquisitions, or failure to consummate or succeed with its
strategic alliances; any negative effect of Nortel's failure to
evolve adequately its financial and managerial control and reporting
systems and processes, manage and grow its business, or create an
effective risk management strategy; and (iii) risks and uncertainties
relating to Nortel's liquidity, financing arrangements and capital
including: the impact of Nortel's most recent restatement and two
previous restatements of its financial statements; any inability of
Nortel to manage cash flow fluctuations to fund working capital
requirements or achieve its business objectives in a timely manner or
obtain additional sources of funding; high levels of debt,
limitations on Nortel capitalizing on business opportunities because
of support facility covenants, or on obtaining additional secured
debt pursuant to the provisions of indentures governing certain of
Nortel's public debt issues and the provisions of its support
facility; any increase of restricted cash requirements for Nortel if
it is unable to secure alternative support for obligations arising
from certain normal course business activities, or any inability of
Nortel's subsidiaries to provide it with sufficient funding; any
negative effect to Nortel of the need to make larger defined benefit
plans contributions in the future or exposure to customer credit
risks or inability of customers to fulfill payment obligations under
customer financing arrangements; any negative impact on Nortel's
ability to make future acquisitions, raise capital, issue debt and
retain employees arising from stock price volatility and further
declines in the market price of Nortel's publicly traded securities,
or the planned share consolidation resulting in a lower total market
capitalization or adverse effect on the liquidity of Nortel's common
shares. For additional information with respect to certain of these
and other factors, see Nortel's Annual Report on Form10-K/A,
Quarterly Report on Form 10-Q and other securities filings with the
SEC. Unless otherwise required by applicable securities laws, Nortel
disclaims any intention or obligation to update or revise any
forward-looking statements, whether as a result of new information,
future events or otherwise.
