Nortel 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 services.

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 services"

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.
