LINTHICUM, Md. -- Ciena® Corporation (Nasdaq: CIEN), thenetwork specialist, today announced that StarHub, Singapore ’sintegrated info-communications service provider, has deployed Ciena’s DN7000™ series of multiservice edge switches in the service provider’srollout of third generation (3G) mobile services, including video calls,video streaming and video Multimedia Messaging Services (MMS).

Ciena’s DN 7200 is being deployed in StarHub’s 3G Universal MobileTelecommunications System (UMTS) Radio Access Network (RAN) to aggregatevoice and data traffic and transport it from the wireless base stationsto the mobile switching centers. The 2G/3G wireless backhaul applicationrepresents a growth opportunity for multiservice edge switches as mobileoperators worldwide transition from TDM to packet-based access networksto support the higher data rates and quality-of-service demands of 3Gservices. The DN 7200 gives StarHub a high-capacity multiserviceplatform with industry-leading 99.9999% system availability, criticalfor keeping pace with increasing customer usage and the high bandwidthrequirements of 3G services.

In fiscal year 2004, StarHub grew its mobile customer base by 30 percentto 1.16 million subscribers. By consolidating multiple leased lines ontoa converged, packet architecture based on the DN 7200, StarHub isreducing its operational costs while simultaneously increasing thecapacity and reliability of its mobile access network to support thisrapid growth in new subscribers and network traffic today and in thefuture.

“As our 3G service portfolio and customer base grows, the capacity andreliability of our mobile access network is paramount to delivering thehighest quality customer experience possible,” said Dave Storrie, headof network and wholesale services for StarHub. “Ciena’s DN 7200immediately reduces the cost and complexity of our mobile access networkand combines uncompromising reliability with the interface and virtualcircuit density to scale our capacity as demand grows for our 3Gservices.”

StarHub has deployed the new Channelized STM-1 capabilities of the DN7000 series to enable an extremely cost-effective solution foraggregating high-density E1 ATM/IMA links in a 3G RAN environment. Withproven IP/MPLS capabilities including PWE3-based ATM, Frame Relay andEthernet pseudowires, Ethernet service interworking and ATM/MPLSmigration features, the DN 7000 series ensures the StarHub accessnetwork is well positioned for 3G radio equipment evolution of the 3GPPUMTS standards to Release 5 and 6.

“As an operator in a region that is experiencing tremendous growth inmobile services, StarHub is an ideal network to showcase the versatilityof the DN 7000 series to converge 3G and legacy mobile services, drivedown the operational costs of 3G backhaul and future-proof the networkfor migration to IP/MPLS,” said Steve Alexander, CTO and general managerof Ciena’s Data Networking Group. “Deployed in networks worldwide tosupport multiple applications ranging from 3G wireless backhaul,migration of Frame Relay and ATM corporate data services to IP/MPLS,Ethernet service interworking, and broadband (DSL/FTTx) aggregation, theDN 7000 series continues to be the technology innovator and marketleader in next generation multiservice edge switching.”

In addition to aggregating the 3G traffic, StarHub is also using the DN7200 to aggregate multiple wireline services, including broadband DSLtraffic and legacy Frame Relay and ATM data services. The DN 7200 allowsmultiple service networks to be collapsed onto a compact, highlyefficient platform to drastically reduce operational costs and simplifynetwork management while maintaining the reliability and quality ofservice customers expect. StarHub is managing its 3G backhaul throughCiena’s ON-Center DN 7000 Manager to assure the most rapid serviceprovisioning and monitoring of new 3G mobile switching centers.
