Nortel Multiservice Switching Solutions Expansion to
Support Demand for Taiwan Cellular Corporation's
Growing 3G Wireless Data Services

TAIPEI, Taiwan--(CCNMatthews - Mar 14, 2005) -

Island-Wide Network Delivers UMTS 3G Broadband Services, Applications

Nortel (NYSE:NT)(TSX:NT) today announced that Taiwan Cellular
Corporation (TCC), a leading mobile operator in Taiwan, has deployed
Nortel multiservice switching solutions to support increased island-wide
demand for secure third generation (3G) wireless broadband data

TCC's current deployment extends Nortel Multiservice Switch (MSS)
coverage, which was first established in July 2003 to support TCC's
initial 3G services. The enhanced network based on Nortel's MSS 7000 and
MSS 15000 provides a cost efficient equipment solution for delivery of
3G data services for TCC's mobile customers using both asynchronous
transfer mode (ATM) and Internet Protocol (IP) technologies. The
MSS-based data network is an integral part of TCC's Universal Mobile
Telecommunication System (UMTS) 3G wireless Radio Access Network (RAN).

"Nortel MSS solutions allow us to continue profiting from our existing
network and evolve it as the market demands to support next generation
capabilities for broadband services and applications," said David
Clarke, senior vice president and chief technology officer, Taiwan
Cellular Corporation. "We chose Nortel based on its proven abilities to
deliver wireless data packet core technologies. With Nortel MSS in our
network, we will be able to broaden our service offerings and optimize
our networking costs."

"Nortel MSS is an integral part of our extensive portfolio of wireless
packet solutions, which is designed to help customers enhance the
communications experience for their subscribers," said Jackson Wu,
managing director, Nortel Taiwan. "This deployment of MSS 7000 and 15000
in a UMTS radio access backhaul network further strengthens Nortel's
leadership position in building high-performance multiservice networks
that span both wireless and wireline networks. The proven ability of our
robust ATM traffic management and QoS features of Nortel MSS to support
wireless IP and TDM voice collectively over a common access network
provides tremendous efficiency for TCC as they grow their UMTS

In addition to enabling UMTS RAN applications, TCC will use the Circuit
Emulation Service (CES) provided by Nortel MSS to transport traffic for
its second generation GSM network as well in order to further reduce
private line costs. TCC also plans to use the rich IP service capability
supported by Nortel MSS to integrate its other IP network traffic into
the Nortel MSS network. The ability of Nortel's MSS to support multiple
services on the same hardware offers TCC tremendous flexibility and
investment protection for overall wireless backhaul consolidation and
demonstrates an ability to evolve as TCC's needs evolve.

Nortel recently unveiled enhancements to its MSS 7000 portfolio, which
addresses the growing market for wireless backhaul applications at 3GSM
World Congress 2005.The enhancements included new higher density
interfaces and a new platform option to reduce wireless networking costs
and improve performance.

Nortel was the global market share leader in multiservice switching
revenue for 15 consecutive quarters as of year-end 2004, according to
Synergy Research Group. With more than 45,000 systems shipped to over
1,500 customer networks, Nortel's Multiservice Switching family has
proven field experience in delivering carrier-grade reliability and
service flexibility for mission critical enterprise and service provider
networks worldwide. Nortel's MSS portfolio is deployed with more than 25
major wireless operators and is delivering proven reliability for
wireless packet networking solutions across GSM/GPRS/UMTS, TDMA and
CDMA/CDMA2000 technologies.
