For T ME dotCom, the Ds in DWDM stand for difference.TIME is a competitive carrier with a fiber optic network thatcovers a large portion of Malaysia and features 5 redundantroutes totaling 6,000 kilometers. Until recently, TIME servedits wholesale and business customers using SDH, but thattechnology did not provide the efficiencies the companywanted for its customers.

All of that has changed since the company deployeda DWDM network based on the Tellabs 7100 OpticalTransport System (OTS). The new network enables TIMEto offer strongly differentiated, high-bandwidth servicesbacked by SLAs. It is supported by a unique mesh protectionscheme that provides sophisticated reroute capability tohelp ensure service even in the event ofmultiple fiber cuts.

After just a few months of operation,the new network already has helpedTIME win new wholesale business fromone major wireless carrier and attractsignificant interest from several others.In addition, the new network capabilitieshave generated strong interest on the partof key enterprises, including several in the financial industry.

Capacity and ConfidenceTIME decided to make the move to DWDM because asAzman Imen, head of network roll-out, project management,for TIME, explained, Our concentration is in the wholesalemarket, and we needed to have a very effective network that

could provide 99.999% reliability.Capacity was another motivation. SDH networks are

subject to congestion, and wholesale customers now wantmore bandwidth, said Hairun Nizam Hashim, transmissionand service management engineer for TIME.

The maximum connection speed that the SDH networkcould support was 10 Gb/s. The new network can supportas many as 88 wavelengths per fiber, with each wavelengthproviding 10 Gb/s connectivity. And in the future, the systemcan be easily upgraded to support 40 Gb/s or even higher datarates per wavelength.

Tellabs was 1 of 6 manufacturers that competed for theTIME business and had not previously supplied any equipmentto the carrier. Tellabs won the business because its productwas rated the highest in TIMEs stringent internal testsand because decision-makers were impressed by Tellabsresponsiveness to their needs.

What interested us most was the mesh protection,Azman said.

Tellabs was one of only a few vendorsthat would be able to support meshprotection capability using GMPLS atthe wavelength level. This was critical forsupporting TIMEs 5 fiber routes runningacross Malaysia.

Tellabs is in the process of enhancingthe Tellabs 7100 OTS to support

this capability, which it has scheduled for delivery in thirdquarter 2010. By using GMPLS-based mesh protection atthe wavelength level, each of TIMEs fiber paths will have 4different backup paths. Traffic can be switched onto thosepaths instantaneously, helping ensure connectivity even inthe event of multiple fiber cuts. This mesh protection schemeenables TIME to offer service with 99.999% reliability.

Proof on a Tight TimelinePrior to deploying DWDM, TIME wanted to do a proofof concept involving a limited installation of the DWDMequipment.

We had a tight deadline, Azman said, and of the vendors participating in the proof of concept, Tellabs was able to keep to this.

Winning Wireless Although the new DWDM network has been operational only sinceDecember 2009, TIME has won wholesale backhaul business from amajor wireless carrier that the company had been trying to land.

What we offered earlier was based on SDH, and they werent verykeen, said Azman Imen, head of project management for TIME. Butonce we offered DWDM, we got the business.

That wireless carrier, along with others, are impressed by thebandwidth and capacity TIME now can provide. With 88 wavelengthsper fiber, capacity is virtually unlimited, and the 99.999% reliabilitythat TIME can provide using its 5 fiber routes and Tellabs GMPLS-based mesh protection scheme was also an important differentiator.

The wireless operators demand bigger bandwidth and theprotection, Azman said. And measured on a per-bit basis, theDWDM-based offering is less expensive than SDH-based alternatives.

TIME is proud of its network and confident that it is ready for any eventuality.

We had a tight deadline, Azman said, and of thevendors participating in the proof of concept, Tellabs wasable to keep to this.

Decision-makers were also impressed with Tellabs globalapproach to customer support. To meet the schedule, Tellabsnot only leveraged its extensive Asia-Pacific-based servicesexpertise, but also sent people from its U.S. operations to helpwith the proof of concept.

We were able to demonstrate the full ROADM functionalityrequired, said Chua Joo Kwang, Tellabs regional salesdirector for Singapore, Malaysia, Thailand, Philippines, HongKong and Taiwan. The proof of concept was completed in avery short time.

Tellabs also made some modifications to the Tellabs 7100

OTS to help meet the unique needs of TIMEs network, basedpartly on submarine cables connecting markets located alongthe countrys 2 coasts. The use of submarine cables could haveincreased the solution costs, but Tellabs minimized the numberof regenerators and other expensive components needed toreduce costs by about 35%.

TIMEs network has a total of 66 nodes and includes 4landing points in Malaysia, as well as 2 points in Singapore.Once Tellabs was chosen, the first phase of the networkupgrade was completed in just 4 weeks, meeting TIMEsambitious deployment schedule. Additional phases of thenetwork upgrade will roll out during 2010.

With the network in operation for just a few months, itstoo early for TIME executives to estimate the savings thus

THE TELLABS 7100 OTS ADvA TAGE

The Tellabs 7100 Optical Transport System (OTS)initially caught TIMEs attention because it providesGMPLS-based mesh protection at the wavelength level.This design offers automatic reroute protection even inthe event of multiple fiber cuts and enables the carrier tooffer 99.999% reliability.

TIME knew that high-resiliency, combined withthe Tellabs 7100 platforms ability to support virtuallyunlimited bandwidth at improved price points, would be ahit with customers. Johari Raja Affendi, Tellabs accountrep for TIME, said that the Tellabs 7100 network will lead

to potential growth in the enterprise market for TIME,

with more Tellabs 7100 Nano products expected tobe deployed and more services revenue generated in theprocess.

Other Tellabs 7100 OTS capabilities also can helpTIME and other service providers differentiate theirservice offerings. One example is remote provisioning,which enables TIME to provision DWDM-based servicesfor its wholesale and enterprise customers in less than 24hours without a truck roll.

Customers also can add new services and locationsquickly by adding new cards rather than new devices.That capability, in turn, can eliminate the need forcustomers to issue requests for proposal when expanding

a service or purchasing a new one, thereby simplifying thesales process. And by eliminating the need forequipment ordering and installation, Tellabsapproach helps minimize customers waitingtimes.

Service providers find the Tellabs 7100 OTSeasy to manage, using the point-and-click capa-bility of the Tellabs 8000 Intelligent NetworkManager (INM). The Tellabs 8000 INM alsoprovides end-to-end performance monitoringand remote troubleshooting using unique test-

ing tools that use live traffic at the packet level.Despite these advanced capabilities, the

Tellabs 7100 OTS is more economical than leg-acy solutions. One of Tellabs North Americanservice provider customers saw savings of upto 65% in CapEx and 85% in OpEx comparedwith its previous network.

Tellabs estimates that an upgrade to theTellabs 7100 OTS delivers 4 times the band-width at less than 75% of the cost of legacysystems.

far, but they expect a significant OpExreduction. The DWDM network providessubstantially higher bandwidth with fewernetwork elements and should be lessexpensive to operate, particularly whencosts are calculated on a per-bit basis.

According to data from other Tellabscustomers, a Tellabs 7100 OTS-basedDWDM solution can deliver 4 times thebandwidth at 50% to 75% of the cost oflegacy systems. Network elements andCapEx can be reduced by up to 65%, andOpEx can be reduced as much as 85%.

Strategy and SupportTo help persuade TIME, Tellabs shared itsexperiences with Verizon, which uses aTellabs 7100 OTS-based DWDM network toserve enterprise customers. TIME was at astage where it was also looking at ways towiden its range of services, as Verizon had.

TIME also liked that Tellabs providedcomprehensive post-sale support. TIME waseligible for Tellabs Enterprise PartnershipProgram, a sales support and trainingprogram aimed at helping Tellabs serviceprovider customers sell more services basedon Tellabs equipment.

Tellabs personnel worked with TIMEs

sales and marketing team to explainthe benefits of features such as GMPLS-based meshprotection. Using the Tellabs 7100 OTS, TIME is able toprovision services for wholesale and enterprise customersin less than 24 hours without a truck roll. (See sidebar.)

Tellabs conducted workshops to explain the benefitsof TIMEs network redundancy and resiliency, and howcustomers could be hooked up and provisioned quickly,Joo Kwang said.

Tellabs also worked with TIME to position TIMEsDWDM-based services against other service provider

offerings. Using this technical information, TIMEsalespeople can demonstrate how their offering providesgreater resiliency and capacity than competitors, includingMalaysias incumbent carrier.

Tellabs participation helped TIME generate substantialinterest from large enterprises, including some Singapore-based financial organizations looking for reliable high-speed connectivity to Malaysias major city Kuala Lumpur,sometimes referred to as simply KL.

They like the fact that we can do add/drops in KL andconnect to Singapore, Azman said. You cant do that

with SDH.

TIMEs Cross Peninsular Cable System (CPCS) networkis now the most robust transborder terrestrial systemever built. Its design only has one goal in mind highavailability. Tough and resilient, TIME is proud of itsnetwork and confident that it is ready for any eventuality.

Designed as a fully meshed network over 5 diverseroutes, CPCS traverses more than 6,000 km with dedicatedfiber optics connecting Thailand and Singapore, CPCSwas designed to provide the ultimate in physical pathprotection. With 5 dedicated fiber routes running along both

coasts, alongside major highways and via utility corridors,TIME does admit to an element of over-engineering.

The results, however, are stunning: up to 99.999%availability. n
