Level 3’s ExperienceOver the last three years, Level 3’s engineering team recently oversaw the design and physical construction of a $10 billion global network from whiteboard to completion. This project was one of the largest construction projects in history when measured by dollars spent per monthIn addition to physical construction, Level 3 built a global operational organization numbering 4,500 people in eleven different countriesLevel 3’s management team has extensive network construction experience through MFS and KiewitLevel 3 built a Tier 1 IP backbone in less than 3 yearsLevel 3 was the first to deploy an MPLS backboneLevel 3 operates the largest SoftSwitch based network in the world. SoftSwitch based service include voice over IP (with PSTN quality) and managed modem services0102 2001 Level 3 Communications, Inc. All Rights Reserved.
3ONTAPSM - World Class Provisioning Process “We are big believers in ONTAP. Level 3 was able to turn up a national private-line backbone for Masergy in less than 10 business days. Such rapid provisioning has enabled Masergy to directly tie capital outlays to solid forecasts of demand and to offer better service to our own customers.”– Gerald Poe, Sr. Mgr. Infrastructure Engineering and ProvisioningMasergyONTAPSM = On-Net Transport Activation ProcessCapacity verification at order entryAcceleration of customer’s revenue recognitionClear commitment at the time of the orderReduced exposure to forecasting riskVendor-neutral architectureServices that are ONTAP enabled mean faster provisioning time and quicker revenue.Time is money.Significant benefit to customers who now can drastically reduce their forecasting risk exposure.ONTAP activation for (3)Link Global Wavelength: 10 days for existing demarcs (with available capacity)ONTAP activation for (3)Link Private Line: 10 days for existing demarcs (with available capacity)Additional demarcation points in select cities where availableONTAP certified capacity has been physically audited and reviewed by field services to ensure the ports are empty and ready for use. This streamlines the process once the order is submitted to the gateway for installation.Sales person can confirm if capacity is available for the exact route requested before providing the customer signature report.Sales person can reserve the capacity which will consume all the necessary logical and physical ports in our provisioning system for 5-15 days to ensure rapid activation of 10 days SLA.NOTE: Customer QuoteWinner of the 2002 Frost & Sullivan Customer Service Innovation Market Engineering Award.ONTAPSM0102 2001 Level 3 Communications, Inc.

The first step in the process, completing the service request, can be completed in .5 days, whereas the industry standard is about 10 days. One of the things during this phase is to make sure all of the appropriate order information is entered on the order before its accepted. By getting this types of information up front, we make sure that there won't be any snags late in the process. Furthermore, we make sure that we set expectations accordingly -- since we can't submit orders involving CPA termination without DLR information, sales will be less likely to say that it's "being worked on" if they still need information from the customer in the first place.The next step, Design, Assign, and Activate takes only 1 day with ONTAP. The industry standard for this step in the provisioning process is about 60 days!The longest step in this 3 step process is the actual test and turn up, and it only takes 3.5 days.As you can see, the entire ONTAP provisioning process is only 5 days. Five days is our internal SLA. We commit to the customer to having their circuits provisioned in 10 days or less. In a recent press release, a competitor claimed to have turned up a circuit in 27 days claiming that it was industry leading. Using ONTAP, Level 3 has actually provisioned an OC12 from Philadelphia to Washington in 17 hours!0102 2001 Level 3 Communications, Inc. All Rights Reserved.

This is a very significant improvement during 2001 as you can see from the chart.(SPEAKER NOTE FYI: 95% met CCD - average of October, November and December. November CCD spiked a bit resulting from the system drop of cross connect functionality into ONTAP. We learned after the drop that the CCD setting process was not working as intended, causing us to miss CCDs. These missed CCDs were invisible to the customer.The trend is continuously improvingNEXT SLIDE: Cycle Time0102 2001 Level 3 Communications, Inc. All Rights Reserved.

10The Level 3 Conduit Advantage The difference between our network and that of our competitors starts at the most base layer, what we call Layer 1 of the OSI model….the Physical Layer. Level 3 has deployed 8-12 conduits in our Intercity Network and anywhere from conduits in our Metro Networks.The deployment of a high conduit count network affords Level 3 the advantage few if any carriers can compete with, a continuously upgradeable network that allows us to carry more and more traffic while at the same time lowering costs through the use of “next generation” improvements in optical transport. These improvements include improvement not only in the optronics, but also in the fiber(s) involved.In order to truly optimize the network design, you must take into accounts all of its components and establish an optronics-fiber relationship that compliments each others capabilities.As the chart on the right side of the slide demonstrates, the introduction of next generation fibers (one every 18 months) over the past several years has reduced the cost of transporting a Gb. With new fibers, we are seeing such improvements as increased regenerator span distances which require less optronics for the transmission of signals and when you consider that the optronics comprise 95% of the CAPEX associated in optical transmission….it adds up. Improvements in the cost structure come as a result of reductions in cost(s) associated with the optics required to transmit the signals. This along with the maturation of DWDM technology enables us to deliver more bandwidth on fewer fibers at a lower cost.The number of conduits also allows us to take advantage of the costs savings associated with simply lighting another fiber (even if its not a next generation fiber) versus having to 1) lay more fiber or 2) deploy costly DWDM gear that will drive up the cost of the service.At some point it is more cost effective to light additional fibers.At some point it is more cost effective to use next generation fiber.Level 3 conduits support both options.0102 2001 Level 3 Communications, Inc.

11Lowering the Cost of Transport Level 3 built its Network to be upgradeable, leveraging new generations of fiber and optronics in 12 parallel conduitsNewest generations purchased in large scale = best unit costSMF10,000.00N2DSFLEAFLevel 3 Cost CurveGen 41,000.00Gen 5Gen 6Gen 7100.00Gen 8Gen 9Unit Cost10.00$ perGbpsmile1.00This slide shows how the concept of Moore’s Law (that for the same cost, computer chip complexity averaged over the past three decades doubled every 18 months) translates to fiber efficiency as well. With each new generation of fiber optic cable released, dispersion factors are reduced and signal loss through attenuation is mitigated. This means that light can travel further and further before it needs costly amplification and regeneration, improving the underlying cost efficiencies of the network.By building our 12 conduit system around the world, Level 3 is optimally positioned to take advantage of the cost benefits of introducing newer more efficient fibers into our network. With 10 spare conduits already in the ground, we will not have to build or dig to deploy newer, more efficient fiber technology into the network. We are the first telecommunications provider whose business plan adopted Moore’s Law right down to the level of the physical fiber core to our network.All cost efficiencies are translated into price benefits for our clients. And since the wavelength product is closest to the fiber layer of our network, these new fiber generations will have the greatest impact on the cost (and therefore the price) of the wavelength product.0.500.0119901995200020052010Source: Corning, Inc., Nortel Networks, Inc., Level 3 Engineering0102 2001 Level 3 Communications, Inc.

The Level 3 Network Is Completely Route DiverseThe Level 3 network does nothave any spurs or laterals – it is completely route-diverse.It is important to be sure that the topology map a provider shows you is a true representation of their network.NetworkSpursSometimes carriers want you to see this.In reality, this isoften what thenetwork trulylooks like.RichmondRichmondThere is an average of 3.9 fiber cuts per 1000 miles of intercity/backbone network per year!When you are evaluating network providers, it is extremely important to make sure that the topology map they show you is a true representation of their network architecture. In today’s competitive market, customers will not tolerate outages. The Level 3 network was designed and built with complete route diversity, ensuring mission-critical service availability levels that we can stand behind based on this design. Many carriers do not have the luxury of a consistent and fully route-diverse network. This is because in the last six years many carriers grew by acquisition and tying together multiple legacy networks to form their “backbones.”POPPOPNon-DiverseCity Laterals/Collapsed Rings0102 2001 Level 3 Communications, Inc.
