Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

3.2 APPROACH TO ENSURE SERVICE QUALITY AND RELIABILITY (L.34.1.3.2)

Getting the backbone network to a customer and ensuring that end-to-end quality meets an Agency’s needs requires a flexible approach for access, the right networking technology, and strict network planning and engineering rules. Qwest brings Agencies all of this on a proven converged platform that also enables service continuity.

For several decades, Qwest has envisioned, designed, engineered, deployed, and operated highly-reliable network services. To accomplish our performance goals, Qwest uses a comprehensive quality assurance plan, quality control techniques, best practices for network design and operations, and industry standard proven technologies to ensure high service quality, and reliability. Many service providers design, purchase, and piece together different technologies, building hybrid networks consisting of disconnected architectures and miscellaneous equipment. Thus, user services are not fully integrated, controlled or managed, which in turn compromises service continuity, quality, and reliability. Qwest's unified network architecture exponentially increases service quality and reliability because it is built on self-healing SONET rings of fiber buried four feet below ground in protective conduits along railroad right of ways. Our fiber network facilities are built to exacting standards for environmental and power redundancy. Additionally, our architecture provides multiple levels of redundancy including switched redundancy at each Point of Presence (POP), plus connectivity to at least three other POPs to ensure service continuation in the event of a switch or path failure. Within 100 milliseconds of a failure, traffic is automatically routed around the failure, and undetected by users.

Qwest recognizes the Government’s concern about access arrangements' quality and reliability between SDPs, and SDPs and POPs, because while our backbone services are reliable, the key measure of our customers’ experience is total service satisfaction from end-to-end. Qwest must also ensure that our connections with other service providers including Local Exchange Carriers (LECs), Competitive LECs (CLECs), Interexchange Carriers (IXCs), and wireless access providers meet our requirements for quality and reliability. To accomplish our requirements for quality and reliability, Qwest has developed a technical approach that combining Commitment, Implementation, and Surveillance and Reporting to achieve the results shown in Figure 3.2-1. Figure 3.2-1. Qwest's Technical Approach Ensures the Delivery of the Highest Quality and Reliable Services to Agencies Surveillance and Commitment Implementation Results Reporting Delivering Service Complying with or Quality Assurance and Quality Control and Delivery of the highest quality services Exceeding Requirements Quality Control Reliability Issues meeting SLAs and AQLs Wherever Possible Proven and Tested Performance and Continuous improvement of service Maintainability Products and Systems Repair Trends responsiveness Network and Systems International and Enhanced platforms for performance and Protocol Errors Interoperability Industry Standards reliability Usability, Security, and Maintain service reliability Security Systems Security Threats Service Reliability avoid service corruption and disruption Utilization Improved strategic planning network build Ease of Expandability Project Planning Percentages outs and service expansion Protection of service quality and reliability Strategic Risk Lowest Risk Risk Events as well as reduced impact if risk events Management Planning occur

Section 3.2.1 describes Qwest's access arrangements, characteristics, performance, and technical capabilities. Section 3.2.2 describes Qwest’s arrangements for exchanging traffic with other providers, and how we maintain service quality during failures. To provide access services, Qwest has a broad variety of agreements with local carriers to ensure flexibility, responsiveness, quality, and reliability. Qwest has strict quality standards directing how we connect with other carriers to maintain this high level of performance. Qwest monitors its services 24x7x365 to ensure that we maintain the

highest quality of services and optimize reliability for our customers. Surveillance monitoring and reporting includes performance measurements and capacity utilization, as well as fault and trouble analysis. Section 3.2.3 conveys how Qwest has designed and engineered its network architecture, implemented system tools, and made full use of standard protocols to handle congestion and failures to ensure resiliency, capacity, and avoidance to meet performance goals, Key Performance Indicators (KPIs), and quality of service. Section 3.2.4 describes the methods Qwest uses to test our services against our engineering designs, as well as to probe and continually monitor our services to ensure that we meet the AQLs for KPIs. Each of Qwest’s backbone data networking services provides the capability of ensuring the delivery of time-sensitive data. Section 3.2.5 explains the technologies that Qwest uses to provide high quality, real-time services.

Qwest’s key differentiator is the ability to provide robust end-to-end solutions, including local access through our own metro facilities and through the traditional Incumbent Local Exchange Carriers (ILECs) and the CLECs. This combination enables Qwest to leverage our own capabilities as an ILEC in 14 states in the western United States as well as those of other ILECs and CLECs to provide robust access solutions that meet Agencies’ needs. To ensure the service quality and reliability of these access services that connect to our backbone, Qwest uses the same discipline and approach that are used to maintain our own facilities-based portions of the service. As a result of our customer-focused approach to delivering communications services, Qwest’s standard access engineering has provided over 99.9 percent end-to-end service availability for Agencies. Qwest has the staff and procedures to engineer extremely high-availability access arrangements. For these, Qwest has averaged over 99.999 percent for the past three years. Measured over the past four years, our operational procedures have also enabled a Mean-Time-to-Repair (MTTR) of less than four hours for Government Agencies. 3.2.1.1 Circuit Switched Access Arrangements (C.2.16.1)

Approach for Monitoring and Measuring VS KPIs & AQLs Qwest uses several techniques to monitor and measure KPIs and AQLs including automated processes to pull data from the root source, summarize it, and display results in red/green colors to indicate goal status. Our approach is to completely automate displaying results so that the focus is on responding to results, not merely reporting them. We established business rules with an automated process to ensure there is no chance of manipulating the data collected from the Service Switching Platforms (SSPs). The following lists the data collected:

• Busy hour call attempts • Call attempts by trunk group • Call blockage by trunk group • Overflow counts by trunk group • SCP timeouts • SS7 link failures Qwest maintains a central data repository for key network performance information. These performance indicators are generated by a combination of system specific statistics (e.g., call attempts generated by the SSP, and monitoring tools and call detail collection). Logs and traps are generated by the SSP, STP, and Service Control Points (SCP), and sent to the Network Monitoring team for instant action. Data is analyzed, formatted, and sent to operations, engineering, and planning for proactive network enhancement and capacity planning. Qwest's daily process includes gathering network statistics for the ongoing monitoring and measurement of KPIs and AQLs in the voice network. We collect general service statistics daily for capacity-level monitoring of circuit and switch Central Processing Unit (CPU) statistics. The statistics include circuit overflow counts, call blockage counts, and CPU utilization percentages. We compare these

statistics against engineering capacity limits to determine the locations where network augments or adjustments are required. Qwest's Switch Management Center performs daily fault management for Signaling and Voice Operations. This center, located in Thornton, CO, is fully staffed 24x7x365. In the event of a catastrophic center failure, a backup center located in Denver, CO, can be made fully operational within a 30-minute window. We perform quarterly failover exercises to ensure proper operations and support functions are maintained. Switch Management uses various Network Management Systems (NMSs) to deliver an alert/log status for operator review and action. Agilent’s NETeXPERT alarm system is used to monitor Time Division Multiplexing (TDM) alarms as well as SS7 signaling alarms. Qwest uses Micromuse’s Netcool® to monitor Simple Network Management Protocol alarms for the Advanced Intelligent Network (AIN) platform - Common Channel Signaling Access Capability / SS7 Network. Tier II technicians in Switch Management maintain “command and control” of alarms and outages reported through the NMSs. They correct and document actions taken to mitigate the alarm condition. They also coordinate additional resources needed for repair and restoration with Field Operations and advanced Technical Support. 3.2.1.1.2 Circuit Switched Data Service (CSDS) Qwest offers switched access arrangements to support CSDS from the local CO servicing the SDP. Qwest pre-subscribes IXC service to the Qwest CSDS.

For the primary IPS circuit, Qwest will leverage Verizon as the access carrier; the Verizon circuit will leverage its own Ethernet transmission equipment, and terminate the circuit in to the Qwest POP at 1500 Eckington Place, Washington DC. Additionally, Qwest will provision a second VLAN on that same circuit. The second VLAN is for NBIP VPNS services. Within the Eckington facility, Qwest will logically provision the primary VLAN for IPS at a rate of 200 Mbps to the Qwest IPS router. For the second VLAN on the Verizon circuit, Qwest will logically provision 200 Mbps on to the Qwest NBIP VPNS router. This way a single circuit will be able to provide two separate services (IPS & NBIP VPNS) using a single carrier's transmission infrastructure.

769002 25 In order to improve the availability and provide access carrier diversity, Qwest is leveraging AT&T as the secondary circuit provider. The second access circuit's primary function is to provide 200 Mbps of NBIP VPNS access to the GAO HQ facility. Additionally, the primary NBIP VPNS circuit will act as the secondary IPS access circuit, and will have a second VLAN created to deliver IPS services. This circuit is to terminate at the Qwest Eckington facility. At Eckington, Qwest will logically connect the NBIP VPN 200 Mbps VLAN to the Qwest NBIP VPN router; the secondary IPS circuit will be provisioned at 200 Mbps to the Qwest IPS router.

With the combination of diverse carrier access, and leveraging the benefits of Ethernet VLANS (using 802.1q), Qwest is able to provide a high availability access solution for both the IPS and NBIP VPNS services to GAO

3.2.1.2.1.1 Custom Access Arrangements Qwest has a long history of supporting critical national infrastructure requirements and will work with the Customer to understand specific requirements for access, POP diversity and availability. Qwest provisions the access, and operates and manages the access links based on the engineering rules provided by the Customer and agreed to by Qwest, taking onto consideration the following factors: ● Site location supporting critical and non-critical traffic and applications. ● Current traffic volume and future traffic growth. ● Access diversity to support the service availability.

Due to the intricacy of providing dual-entrance and/or highly-available access facilities, custom access arrangements may be required to address the access factors described above. A custom access arrangement is applicable when one or more of the following conditions are present: 1. An access arrangement is not available and, at the request of the Customer, Qwest provides a custom access arrangement service through the implementation, rearrangement or relocation of physical plant solely for the Customer-requested custom access arrangement. 2. At the request of the Customer, Qwest creates a custom access arrangement using a route (customer prem to LEC SWC, LEC SWC to

Alternate Qwest POP or some other type of route) other than that which Qwest would otherwise utilize in order to provide an access arrangement for the Customer 3. At the request of the Customer, Qwest implements a greater quantity of access arrangement capacity than that which Qwest would otherwise implement in order to fulfill the Customer's initial requirements for access arrangement service (customer prem to LEC SWC, LEC SWC to Alternate Qwest POP or some other type of route); 4. The access arrangement is not available and, at the request of the Customer, Qwest expedites the implementation of the custom access arrangement at greater expense than would otherwise be incurred for an access arrangement; 5. An access arrangement is not available and, at the request of the Customer, Qwest implements a temporary custom access arrangement to provide service for the period during which the permanent access arrangement is under construction.

For custom access arrangements, Qwest will provide design, engineering, implementation, testing, turn-up services, and lifecycle management. Qwest engineers will work with the Customer to plan the required routes and infrastructure requirements for the custom access arrangement. Custom access arrangements will require additional time to implement. The Customer should plan ahead and consider that a longer than normal lead time is required to provide a custom access arrangement. Because the access arrangement is custom, the Networx on-time provisioning SLA does not apply to Custom Access Arrangements. Table 3.2.1.2.1-2 provides the Custom Access Arrangement CLINS

• Bit error rate acceptable standards – DS-3 – 10-11 – OC-3/OC-12 – 10-13 – OC-48 – 10-14 Approach for Monitoring and Measuring WLNAA KPIs and AQLs Qwest monitors and measures the KPIs and AQLs for all transport services using automated processes that pull data from its primary source, summarize it, and present user-friendly Web reports. The Web displays actual performance results: results that meet performance goals are green, results that do not meet performance goals are presented in red. Qwest completely automates the process, from data collection to Web display, so that both Qwest and our customers stay focused on improving performance results rather than “report generation.” Process automation also establishes business rules and ensures that customers receive completely accurate performance data. We use the Statistical Analysis System (SAS) software package to display the Network Reliability Scorecard, with KPIs, objectives, and an indication of whether the objectives are met or missed for each reporting period. The scorecard is our tool to show both upper management and network management the current health of the network. Qwest's executives review the scorecard daily to ensure issues receive priority attention and focus. Our network management teams review the scorecard every day to ensure that Qwest meets AQL levels consistently. All Qwest products use a single, industry-leading, commercial-off-the-shelf trouble ticketing system customized for Qwest's services. From this system, we collect many useful metrics that we use internally to evaluate and improve our processes, including Time-to-Resolve (TTR). We use the same business rules the Government requires for its services to calculate our TTR. The Network Elements (NEs) capture and maintain performance data on equipment and circuits. Qwest uses Spirent’s performance management tool to

55 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

collect performance data from the NEs on a pre-established time cycle (e.g., once a day, every 15 minutes) and to store the data in a server for monitoring and reporting. Qwest uses this data in several ways: (1) We compare performance results to the performance thresholds that we set to trigger alarms for monitoring the network; (2) Results create auto-generated trouble tickets in our trouble ticketing system for immediate resolution; (3) Results are used to calculate the KPIs, which are displayed on our network scorecard, and ensure we are meeting our AQLs. Qwest's network performance monitoring and measurement procedures allow us to deliver industry-leading network availability and reliability, as well as the following, more specific, benefits: • End-to-end service visibility across technology/layers, including High bit-rate Digital Subscriber Line (HDSL) and next-generation Network Element (NE) support • Service impact analysis correlates facility/equipment faults to customer services • Automated, expert analysis and OSS integration to streamline processing • Ability to copy results of diagnostics and Reason for Outage to trouble ticket and to automate the ticketing process • Customer-focused Quality of Service (QoS)/SLA management and Web access • Customization to fit current and future operational needs Qwest’s approach for monitoring and measuring performance indicators is to use Threshold Crossing Alarms (TCA) that alert technicians when Qwest-defined performance thresholds are reached. The technicians respond by eliminating potential sources of trouble in elements. Rather than waiting for a repair ticket to start working on resolving a trouble case, Qwest identifies potential performance problems early and trouble is diagnosed proactively. This approach yields less network downtime and faster resolution of network problems.

ID # Feature Qwest Technical Approach Qwest orders and installs diverse routes and access types between Agency locations and the Qwest network. Qwest has systems and processes in place to flag all diverse circuits, thereby preventing any inadvertent change to the routing of these circuits. Diverse circuits do not share any common telecommunications facilities and offices and are separated horizontally by a minimum of 30 feet and vertically by a minimum of 2 feet. As a general practice, Qwest routes the traffic on the primary path to Access ensure minimal latency and that adequate capacity will be available on the alternate path, though the Route or 1 traffic pattern is at the Agency discretion. For those services that have defined a critical high Path availability requirement, Qwest has defined SEDs that provide automatic end-to-end protection Diversity switching. In cases where Agencies are using GFE, the protection switching capability is necessary to take advantage of the alternate access path. Qwest will provide the Agency with a diagram of circuit diversity within 30 calendar days of diverse access implementation and when any Agency-driven routing changes are made. When diversity is not available, Qwest will work with the Agency to determine the best possible, acceptable alternative. Where available, Qwest will provide the Agency with circuit routing plans conforming to any Agency- Access defined route avoidance specifications. Where not available, Qwest will provide documented reasons Route or for unavailability. Qwest will provide the Agency with a diagram of circuit route avoidance within 30 2 Path calendar days of circuit route avoidance and when any Agency-driven routing changes are made. Avoidance Qwest has systems and processes in place to flag any route or path avoidance circuits, thereby avoiding any inadvertent change to the circuit route.

Approach for Monitoring and Measuring WLSAA KPIs and AQLs Qwest monitors and measures the KPIs and AQLs for all services using automated processes that pull data from its primary source, summarize it, and present user-friendly Web reports. The Web displays actual performance results: results that meet performance goals are green, results that do not meet performance goals are presented in red. Qwest completely automates the process, from data collection to Web display, so that both Qwest and our customers stay focused on improving performance results rather than “report generation.” Process automation also establishes business rules and ensures that customers receive completely accurate performance data. For Network KPIs, we use the SAS software package to display the Network Reliability Scorecard with the KPIs, the objectives, and an indication of whether the objectives are met or missed for each reporting period. The scorecard is our tool to

67 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

show both upper management and network management the current health of the network. The scorecard is reviewed daily at the executive level to ensure the proper attention and focus and by our network management teams to ensure that AQLs are met consistently. All Qwest products use a single, industry-leading, commercial-off-the-shelf trouble ticketing system customized for Qwest's services. From this system, we collect many useful metrics that we use internally to evaluate and improve our processes, including TTR. We use the same business rules as the Government requires for its services to calculate our TTR. The NEs capture and maintain performance data on equipment and circuits. Qwest uses Spirent’s performance management tool to collect performance data from the NEs on a pre-established time cycle (e.g., once a day, every 15 minutes) and to store the data in a server for monitoring and reporting. Qwest uses this data in several ways: (1) We compare performance results to the performance thresholds that we set to trigger alarms for monitoring the network; (2) Results create auto-generated trouble tickets in our trouble ticketing system for immediate resolution; (3) Results are used to calculate the KPIs, which are displayed on our network scorecard and ensure we are meeting our AQLs. Qwest's network performance monitoring and measurement procedures allow us to deliver industry-leading network availability and reliability, as well as the following more specific benefits: • End-to-end service visibility, across technology/layers, including HDSL and next- generation NE support • Service impact analysis - correlates facility/equipment faults to customer services • Automated, expert analysis and OSS integration to streamline processing • Ability to copy result to trouble ticket and to automate the ticketing process

• Customer-focused QoS/SLA management and Web access • Customization to fit current and future operational needs Qwest’s approach for monitoring and measuring performance indicators is to use Threshold Crossing Alarms that alert technicians when Qwest-defined performance thresholds are crossed. The technicians respond by eliminating potential sources of trouble in elements. Rather than waiting for a repair ticket to start working on resolving a trouble case, Qwest identifies potential performance problems early and trouble is diagnosed proactively. This approach yields less network downtime and faster resolution of network problems. 3.2.1.5 Satellite Access Arrangement (SatAA) (C.2.16.2.4) Qwest is offering SatAA with our partner AGS to provide speeds of T1 through DS3 to support Agency performance metrics for availability and disaster recovery.

technical issues for provisioning to provisioning timeframes, billing, monitoring, and trouble management. Internet Peering Our major peering locations are distributed throughout CONUS and include: Atlanta, Chicago, Dallas, Los Angles Metro, New York Metro, San Francisco Metro, Seattle, and Washington, D.C. Metro. Qwest’s standards require peering with each major carrier at the OC-48c level (2.5Gbps) at each major peering location. Unique in the industry, Qwest backs our peering capabilities with an SLA for access to the major Internet provider’s networks. Much of our peering is done at carrier-neutral locations where there are multiple fiber and access providers. Qwest currently has approximately 115 Gbps of domestic peering, which includes approximately 30 Gbps of international peering with a total of approximately 135 peering points. Our peering list includes: AboveNet, Aleron, AOL, AT&T, BCE Nexxia (Bell Canada), BTIgnite, China Telecom, Cogent, DACOM, Deutsche Telekom, ESNet, France Telecom, Global Crossing, IIJ, Japan Telecom, KDD, Level 3, NASA, Verio, Reach, Savvis, Singtel, Sprint, Swisscom, Telefonica, Teleglobe, TeliaSonera, Telus, Telstra, Tiscali, UUNet, WilTel, and XO. Qwest’s Tier 1 Internet is fifth on the Netconfigs in Autonomous Systems (AS) connectivity rankings, and 5th in AS ranking by The Cooperative Association for Internet Data Analysis. This means that Qwest has excellent connectivity to the Internet. In addition, Qwest keeps traffic on our high-performance, high-capacity Internet backbone as long as possible, delivering our customers’ transit traffic as closely as possible to its peer destination, improving our customers’ performance. To ensure continued peering performance, we gather are review usage reports for all peering circuits weekly. Any peering circuits reaching 95th percentile utilization in either direction, or average usage of 50 percent or more, are flagged to

be upgraded. In addition, if peak utilization over a 24-hour period reaches 75 percent of the aggregate peering capacity that has been established with that particular peer, the peering capacity with that peer is augmented. Qwest is an active member of the Network Reliability Steering Committee (NRSC). The NRSC was formed to monitor network reliability utilizing the information contained in major outage reports filed with the FCC. The committee’s mission is to ensure a continued high level of network reliability.

3.2.3 Congestion Flow Strategies, Control and Redundancy (L.34.1.3.2(c)) Qwest has tremendous backbone bandwidth based on our implementation of DWDM and aggressive capacity planning to ensure no congestion in our data and voice services networks. Qwest data networks have significant POP redundancy,

83 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

including multiple redundant core MPLS routers, access routers, route diverse wavelength, and SONET access to multiple other POPs. Traditional voice switches have redundant SS7 links, SONET trunking, and redundant control processors and switch fabrics. Our Next Generation Switch (our Voice over Internet Protocol (VoIP) platform) has redundant control servers and VoIP-to- Public Switched Telephone Network (PSTN) gateways. Our network planning engineers examine all failure modes and design network capacity and switch or router redundancy to ensure performance during failures. While Qwest engineers our network to handle congestion, our primary approach to maintaining service quality is to plan, engineer, and operate the network to avoid congestion and single points of failure. Physical Plant Resiliency Resiliency starts right with the fundamental building block of all modern nationwide networks—our fiber and optical transport systems. Qwest started as a network construction company, and using our pioneering construction methods placed our fiber in High-Density Poly Ethylene conduit buried approximately four feet below grade along railroad Rights-of-Way (ROW). It is this construction technique that has protected our fiber even in the face of catastrophic events like hurricane Katrina. Our ROW facilities are designed to the highest carrier-quality standards including: • Dual entrance facilities for our route-diverse fiber backbone • Dual D.C. power systems with generator back-up • Redundant heating, ventilation, and air conditioning systems • Full environmental and security alarms to ensure proper facility operation Optical Transport Architecture Resiliency The next step in redundancy and resiliency is our backbone optical transport system:

84 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

• Qwest optical transport services are based on route-diverse SONET four-fiber bi-directional line-switched rings (4F-BLSR). This technology allows Qwest to provide an extremely low bit error rate, 10-15 (BER); this technology also ensures extremely high availability of over 99.999 percent. • 4F-BLSR technology means that Qwest has 100 percent redundancy for all fiber and transport equipment failures, and approximately 50-100 millisecond restoration times for any failures. In fact, none of Qwest’s SONET transport customers lost any traffic during the recent damage caused by hurricane Katrina; our POP near the New Orleans Superdome never lost service. Monthly transport utilization reports are used to monitor congestion and traffic flow. As certain threshold levels are reached, the traffic patterns are reviewed to determine if a new system is required. As part of the review, the system architecture is analyzed to determine if a there is a better design that could be deployed. The system could have new nodes inserted, or drop locations could be changed to route traffic more efficiently. Our goal is to route traffic over the shortest distance with the least number of hubs as possible. The SONET 4F-BLSR backbone network provides 192 STS-1 slots between segments per wavelength on our DWDM optical transport system. This allows for a great deal of flexibility in terms of the services we can provide. As requirements change, Qwest has an established process to quickly convert drop capacity in order to meet the needs of our customer’s needs. In addition, intermediate locations between current access POPs, such as optical amplifier and regenerator sites, can be converted to provide drops if the traffic patterns indicate it is necessary. New capacity, 10 Gbps (OC-192) at a time, can be quickly added to our SONET rings or wavelength services network by the straightforward addition of transport cards only where required. Qwest has ample capacity on our existing transport system for the addition of capacity growth in the foreseeable future.

Data Transport Services, ATM, FR, and IP-based Resiliency Network resiliency is also built into our data network services. For example, even though our flagship network uses 10 Gbps unprotected wavelength links to connect our private MPLS core routers, our engineering and use of technology ensures no single-point-of-failure or service degradation in the event of failures. For example: • Qwest’s IP-based MPLS fast-forwarding core design uses MPLS Fast Re-Route, (FRR) which provides pre-provisioned multi-path healing for all Qwest IP services to ensure 50-100 millisecond range service restoration even in the event of catastrophic backbone circuit or router failure. • Qwest’s Inter-networked ATM and FR network uses proven Layer 2 restoration mechanisms that ensure services are rapidly restored in the event of a backbone or switch failure. Qwest did temporarily lose unprotected wavelength services between Mobile, AL, and New Orleans, LA in the wake of hurricane Katrina. However, our use of MPLS FRR and ATM virtual circuit remapping meant that no active Qwest data network customer lost services. In combination with our strict capacity planning approach for these services, Qwest never violated its Service Level Agreements for packet, Frame, cell, latency, or jitter during the time that core backbone links were unavailable. The Qwest IP backbone is already MPLS-enabled and runs resource reservation protocol. This provides a solid foundation upon which to build end-to- end bandwidth management. This approach to traffic engineering allows sets of bandwidth-guaranteed label switched paths to carry different classes of traffic— meaning our core will ensure that our VoIP and MPLS VPN traffic is prioritized over Internet-type service—further ensuring the ability to handle both predicted traffic loads as well as increased loads due to unexpected events such as trunk or router failures.

86 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

Qwest utilizes only carrier class equipment to achieve high network availability. Throughout the equipment life cycle process, from technology insertion to decommissioning, Qwest employs a rigorous testing and evaluation program to ensure the equipment we select for our network meets our network availability objectives. Qwest’s technology management department evaluates the equipment reliability analysis and sparing strategy and determines which equipment components need to be redundant. To ensure high availability of our VoIP, IP, ATM, FR and other IP-based services, Qwest employs redundant port cards, line cards, control processors, and switching fabrics in our carrier class equipment. This redundant and reliable equipment is then replicated either locally or in a geographically diverse location. Figure 3.2.3-1 shows a diagram of our typical TeraPoP data network architecture. In the event of a loss of a single router or switch (combined with our rigorous capacity planning methodology), an Agency will not only see continued service, but also will experience no degradation of service. Qwest networks are built with significant extra capacity to allow for bursting, and to absorb changes in traffic patterns when failure conditions exist. Qwest also adopts a stringent capacity-planning methodology to ensure there is enough room in the backbone network to accommodate traffic surges in the event of micro bursts, denial of service attacks, or link failures. By rigorously following such capacity planning rules, we ensure that the Qwest backbone network will maintain service quality for Agencies. As shown in Figure 3.2.3-1, every Private MPLS core POP and IP-services POP (TeraPOP) is connected via multiple backbone circuits to a minimum of two other TeraPOPs using physical diverse facilities. Qwest gathers reports for all core backbone circuits. Any individual backbone circuit with a 95th percentile utilization greater than 40 percent is flagged for upgrade. In addition to simply monitoring circuit utilization under normal operating conditions, traffic flows on the backbone

87 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

are regularly modeled for potential failures (for example, fiber cuts, hardware failures, etc.). Such backbone capacity upgrades are typically completed within 45 days of the action being initiated. For the integrated Qwest ATM and FR network, there is a second set of statistics that we watch closely in conjunction with the monitoring of the usage statistics. This other set of statistics is the allocated Equivalent Bandwidth (EQBW). EQBW is the amount of bandwidth reserved for each provisioned virtual circuit

88 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

based on its QoS class and the associated traffic descriptor (SCR, MBS and PCR) values. An ATM trunk is flagged for possible upgrade if either set of statistics (that is, actual usage or the EQBW) reaches any threshold that would affect customer performance during potential failures. In addition to core backbone capacity, every edge aggregation device for IP, ATM, or FR services has a minimum of two uplinks into two different core backbone devices. Usage statistics are gathered on every edge aggregation circuit and reports are generated using these samples for review weekly. Any edge aggregation circuit with usage greater than 35 percent (in either direction) is flagged for possible upgrade. Utilization is measured using the 95th percentile of five-minute samples over a week’s period. Aggregate usage on the two uplink circuits is always managed to be less than 100 percent of an individual uplink circuit. For example, for a given edge device, if traffic usage is at 35 percent on one link and 10 percent on the other, we would not upgrade. If the usage is 35 percent on one uplink and 65 percent on the other (aggregate peak usage is 100 percent), the access capacity will be increased. Such capacity upgrades are typically completed within 30 days of the action being initiated. The combination of our backbone core and access architecture, the use of advanced MPLS-based traffic engineering, and our conservative backbone and access router link upgrade policy significantly limits the potential for degraded customer service during potential failures. Internet Services Resiliency For Internet services, our Tier 1 Internet backbone inherits the resiliency of the underlying private MPLS core. For Internet connectivity, peering capacity is the next critical factor in maintaining services in the event of link or facility failures. As described in Section 3.2.2, Qwest peers with all major carriers in seven geographically diverse locations throughout the United States. If peering connections exceed 50 percent average utilization (or peak utilization over a 24-

89 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

hour period reaches 75 percent), then the peering connections to that ISP are targeted for an upgrade. Qwest has the ability to respond to unusual and extreme traffic flows. This includes the ability to distribute black-hole routes to the edges of the network and the ability to control the flow of traffic between services. Black-hole routing allows targeted, granular, route-level traffic control through a standard NOC interface. Voice Services Architecture Resiliency The Qwest long distance VS network provides the service and switching plane for generic VS and enhanced services, including toll free. The Qwest VS platform is structured as a meshed network architecture. It consists of 34 Nortel DMS-250, 13 next generation VoIP switches (NGS), and Nortel DMS-500 international gateways. No single hardware failure will cause a loss of an entire switch or switch complex. Each DMS-250 or Next Generation Architecture (NGA) complex supports a particular set of serving areas in the national network. Each switch has a community of interest whereby a call originating on that switch will directly terminate off of that switch. This community of interest is typically 6-10 percent. Any voice traffic that originates and terminates on different switches will have several paths within the network to reach the destination. The call may take a direct Inter-machine Trunk from the originating switch to the terminating switch, or it may tandem through one of the other switches within the network. All of the NGA complexes are interconnected via the Qwest internal IP backbone. Traffic between two NGA complexes is packetized and routed over the IP backbone. Qwest manages this IP network such that any uplink carrying voice traffic from a NGA is no more than 40 percent utilized NGA during normal conditions. Therefore, using a 20 percent overhead factor, a complete single point outage can be fully handled by the redundant element. Or, if a traffic spike occurs, it is easily absorbed under normal conditions.

90 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

Qwest currently uses a hubbing arrangement for internal tandeming of traffic. Calls originating on one DMS-250 and terminating on another DMS-250 will attempt the direct route first. If the direct route is not available, the call will route to a NGA complex. The NGA complex will then chose a direct route through the closest NGA terminating complex to the terminating DMS-250. If a single circuit outage occurs, Qwest internal diversity of IMT paths recovers the majority of the traffic between two destinations. The amount of recovery depends on the extent of circuit damage and the traffic levels between two points. There are typically two to three IMT groups between any originating and terminating switch locations. Qwest handles international traffic through three different gateways: Seattle, Los Angeles and Jersey City. In addition, Qwest also has agreements and connectivity in place with other carriers to handle overflow or traffic in the event of a Qwest switch or gateway failure. If the gateway is rendered inoperable, then each originating switch in the Qwest network has a fail-safe path directly to a fail-over carrier that will complete the calls. For congestion scenarios, Qwest may implement a directional reservation on a trunk group or trunk groups into a specifically congested area. These controls are put in place to ensure that circuits are reserved for calls leaving a specific area during a congestion event. Qwest’s current policy is to engineer traffic such that switches do not exceed 80 percent of their CPU capacity during daily network busy hours. Qwest VoIP and IP telephony services are built on the NGA. The NGA is built upon a highly reliable hardware platform. The hardware platform utilizes either a 1+1 or N+1 scheme for all critical components. All of the NGA complexes are interconnected via the Qwest internal IP backbone. Traffic between two NGA complexes is packetized and routed over the IP backbone using a dedicated IP network converged on our Private MPLS Core.

91 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

Qwest manages this IP network such that any uplink carrying voice traffic from a NGA is no more than 40 percent utilized during normal conditions. Therefore, using a 20 percent overhead factor, a complete single point outage can be fully handled by the redundant element, or, if a traffic spike occurs, it is easily absorbed under normal conditions. For VoIP-originated and terminating traffic, Qwest has implemented Session Border Control (SBC) technology that throttles traffic on a per end-point basis. This functionality allows Qwest to limit traffic from specific customer end-points (IP addresses) to prevent a single customer from flooding the network with traffic. Local Access Loop Resiliency For last-mile access into a customer facility, Qwest offers a local loop diversity option. Qwest’s local loop diversity enhancement includes: • A defined relationship is maintained between the primary circuit and the diversely routed circuit(s) • Resiliency is custom-engineered by Qwest based upon available facilities • Both circuits are identified and maintained in the Qwest database systems as diversely related circuits Network Access Resiliency Qwest can also provide additional resiliency by enabling diversely routed access circuits to terminate at diverse Qwest equipment – either in the same POP or another POP. Qwest has provisioning capabilities to ensure that a defined relationship is maintained between the primary circuit and the diversely routed circuit. This relationship includes: • Custom-engineering by Qwest based upon available Qwest facilities • Provisioning as a distinct transmission path(s) from the primary circuit

92 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

• Identification and marking in Qwest’s database systems as related primary and diversely routed circuit(s) Network access diversity is available in the following configurations (either separately or in combination where appropriate, subject to available network facilities and technical feasibility): • TeraPOP Diversity – Accesses a separate network gateway in a diverse TeraPOP. The diversely routed circuit terminates in a physically separate Qwest TeraPOP from the primary network connection. The service is provided to the Qwest-designated demarcation point. • Gateway Diversity – Allows customers to connect to a secondary network access router or switch in the same TeraPOP. • Card Diversity – An entry-level Qwest networking diversity solution. It delivers a diverse local loop with a connection into a diverse card on the same network gateway. Quality of Service and Class of Service For traditional data services, Qwest provides four classes of service for ATM and three for FR. The classes are mapped into virtual circuits with an associated traffic contract. Qwest’s implementation of these services ensures that these traffic contracts are handled end-to-end on a per virtual circuit basis, ensuring an extremely high probability that a customer will achieve 100 percent of their guaranteed minimum traffic rate under both expected and unexpected traffic loads. When combined, our core switch redundancy and our strict backbone and access switch link capacity upgrades policy also ensure that Agency performance will not be affected by the failure of a core switch or backbone trunk. For our IP-based services, Qwest ensures that our MPLS core backbone design, bandwidth and bandwidth for the access routers have enough capacity to meet expected demand as well as unexpected peak demand. As described earlier, the network is designed so that no core route or backbone link failure will cause

93 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

utilization to exceed approximately 80 percent of the 95th percentile on any remaining backbone trunks. In addition to using backbone capacity to ensure good performance in the event of failures or unexpected loads, Qwest is implementing DiffServ-TE. This mechanism enables the prioritization of the private MPLS core Label Switch Paths (LSPs) that are used to provide bandwidth for Qwest IP-based services. This means that our VoIP traffic has higher priority than MPLS VPN traffic, which has a higher priority than Internet-bearing LSPs. PCS Resiliency The base stations used to support our PCS services incorporate significant features to manage congestion and flow control, and maintain service during equipment failures. • Congestion and flow control – Exceptional congestion may occur, causing RF resource limitations or back-haul limitations at a given cell site. When such congestion occurs at a cell site, that site will increase the probability of rejecting of new, incoming traffic to ensure that current traffic is maintained. As resources at the cell site become available, the site will accept new traffic again. In high traffic areas, cell sites typically overlap, and another cell site will carry the rejected traffic. This provides a robust multi-cell redundancy system, and only when large clusters of multiple cell sites are affected by exceptionally heavy traffic will the blocking probability increase significantly. • Flexibility – Wireless network capacity planning is performed based on historical traffic data and projected growth in customer and usage during the busy hour. Every network element in the wireless network is designed for a certain blocking statistic during the busy hour (typically less than 1 percent). Base stations with multiple carriers distribute the traffic within the base station to maximize the amount of traffic it can handle. During planned special events, a “cell-on-wheels” may be deployed to provide additional capacity to meet temporary usage needs.

94 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

Our experience in natural disasters (such as a major Seattle earthquake) demonstrates the robust nature of the network and proves that these “cells-on- wheels” can be deployed efficiently within few hours. • Maintain Service Quality – Each base station is equipped with a redundant processor card in hot stand-by such that base station failures are minimized. All other network elements are pooled across multiple sectors or channels for each base station, offering inherent redundancy. Hand-off capability to neighboring base stations provides overlapping coverage. Every base station is equipped with batteries to provide two to four hours of service in case of a power outage. Over the air, CDMA standards provide the best reliability. The use of CDMA spread spectrum is an efficient way to mitigate interference, and a call is typically carried in soft hand-off between the mobile and several base stations (up to six), thus reducing the impact of transmission failures, obstacles or interferences. 3.2.4 Approach to Performing Verification of Individual Services (L.32.1.3.2(d)) Standard Test Procedures (Req_ ID 2267) Qwest will deliver the Networx Services Verification Test Plan which will detail the standard test procedures that will be used by Qwest to verify, at a minimum, that the services delivered under the contract meet the KPI/AQL thresholds including SDP-to-SDP measurements for the ordered service as specified in Section C.2, Technical Requirements, prior to delivering the ordered service to the customer. Qwest is drafting a Networx Services Verification Test Plan in preparation for its delivery due date, which is 60 days after contract award. Process and Procedures (Req_ID 2266) The Networx Services Verification Test Plan will contain the individual service test plans that Qwest uses on a regular basis, as well as team member

95 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

provided services. As new services are requested by the Government, these individual Service Test Plans will be incorporated into the Networx Services Verification Test Plan. The individual test plans will be reviewed with the Government prior to adding any new service to the Networx Program. The Government may comment and suggest changes or improvements to the service test plan to be considered for incorporation into the plan. Testing at Time of Initial Service Delivery (Req_ ID 2264) Each time a service is delivered to an Agency for the first time, the individual service test plan will be executed. Each individual service test plan will include validation of SDP-to-SDP AQL achievement. Qwest will provide a copy of the service test as part of the acceptance process each time a service is delivered to the Government. Service-Specific Test Plan Attachments (Req_ ID 2262) As new services are requested by the Government, Qwest will provide the associated Service Test Plans and they will be incorporated into the Networx Services Test Plan. The individual service test plans will be reviewed with the Government prior to adding any new service to the Networx Program. The Government may comment and suggest changes or improvements for the service test plan to be considered for incorporation into the plan. GSA Approval (Req_ ID 7675) The Qwest Networx CPO will be responsible for managing the approval process with the GSA for the Networx Services Verification Test Plan. Qwest will submit the Plan for approval in accordance with Section E.2.2 and Section F and will delivery it at 60 days after Notice to Proceed. Notice of Changes (Req_ ID 7676) Each time Qwest’s Networx Verification Test Plan is changed, due to such activities as addition of a service-specific test plan, Qwest will notify the Government prior to release of the plan. The Qwest CPO will have responsibility for

96 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

communicating the test changes, so that the Government is assured that successful service implementation will include adequate testing. Qwest will use the contract modification process established by the GSA to offer new services under the Networx program. After approval from the GSA, Qwest will provide updates to relevant information such as the Networx Verification Test Plan as standard procedure. Approach For all services requested in Networx, Qwest executes several testing gates beginning at proof-of-concept and continuing through the product life cycle to ensure that services perform as specified. Qwest thoroughly tests all hardware equipment and software loads in our own labs before deploying them on our network. This ensures that bugs or incompatibility problems are identified in our test environment, virtually eliminating the possibility that a new hardware or software install will create a service interruption. For contingencies, a version of all network elements and corresponding software is maintained in Qwest’s labs to provide direct, organic support in the event troubles occur. Testing occurs through the life cycle of all of our products, services, and network resources to ensure services are meeting our stringent requirements. As new services are tested in proof-of-concept, Qwest develops the processes and testing procedures necessary to operate and maintain the services and continues testing as network elements and software solutions are evaluated and selected. Even after we have selected a solution, testing continues through integration and product roll-out. Each network element is tested according to industry best practices after installation, before customer traffic is provisioned. Software upgrades are always tested in Qwest labs to ensure they will operate appropriately prior to deployment on our live network elements. Software upgrades are non-service impacting wherever possible and can be reverted to previous versions without disrupting network operations elements in the extremely

97 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

unlikely event the software load is not successful. All upgrades, including version updates and patches, are tested. Our procurement processes ensure that vendors execute extensive testing of incremental additions such as optical transponders, switching blades, SFP/GBIC pluggables, and other devices, prior to shipping to Qwest. Before handing any service over to our customers, the provisioned circuits are also tested to ensure they meet our standards. Testing continues throughout the life cycle. Many services are supported by integrated monitoring capabilities to measure bit error rate, latency, jitter, grade of service and other KPIs, we use to monitor the systems’ effectiveness. Some systems allow for proactive testing on our live network. For example, we measure performance of our long-haul optical transponders and replace them immediately if they deviate from suppliers’ specifications. Throughout the life cycle of all of our services, we monitor and measure the KPIs for AQLs via automated processes that pull data from the root source, summarize it, and display it via Web tools. These Web tools display actual results and indicate goal status via red/green color coding. Our approach is to completely automate the display of results from data collection to Web display so that the focus is on acting on the results rather than reporting them. Further, by automating the process, we ensure that business rules are established and there is no chance of manipulation. The resulting SDP-to-SDP AQL metrics for each service are discussed in detail in each service section. 3.2.4.1 POP-to-POP Monitoring as an Element in Networx AQL Verification

In addition to SDP-to-SDP monitoring, Qwest measures its own internal network SLAs. We use an SAS to display the Network Reliability Scorecard with these SLAs, the objectives, and an indication of whether the objectives are met or

98 GS00T07NSD0002 July 30, 2010 Data contained on this page is subject to the restrictions on the title page of this contract. Networx Universal 3.2 Service Quality and Reliability Approach - QU0264.02E

missed for each reporting period. The scorecard is our tool to show both upper management and network management the current health of the network. Ongoing trend analysis of POP-to-POP performance supports verification and testing of SDP-to-SDP performance because POP-to-POP performance is a contributing factor in achievement of Networx AQLs. On our transport network (services of Private Line, SONET, Optical Wavelength, Dark Fiber, and Ethernet), new NEs undergo a comprehensive testing process before they are deployed in the network. All the functional aspects that will be deployed are tested to ensure that the equipment performs properly. In addition, interoperability with existing NEs is tested. Once the NE has been approved for use in the network, each new deployment is tested before it is released for network use. While Qwest uses a standard testing period, the interval can be adjusted to meet the customer’s requirements. After the system has passed the test, each individual circuit that is to be placed is also tested to ensure acceptable performance. As shown in Figure 3.2.4-1, before any circuit is placed into service, the metrics are measured and the circuits must exceed every AQL to ensure that the circuits are ready to carry traffic. Figure 3.2.4-1. Table of Qwest POP-to-POP Metrics Captured (by Service) for Transport Services

The NEs capture and maintain performance data at both the equipment and circuit level. We use Spirent’s performance management tool to reach out to all of the NEs for performance data on a cycle that we set (for example, once a day, every 15 minutes) and store the data into a server for monitoring and reporting. The data is used in several ways. • Results are compared to thresholds to trigger alarms • Results create auto-generated trouble tickets for immediate resolution • Results are used to calculate the KPIs to ensure we are meeting our AQLs For DFS, our testing processes before turning over the fiber to the customer include measuring the attenuation coefficient to verify that it is within specifications. Qwest will measure polarization mode dispersion, chromatic dispersion, reflectance, return loss, and insertion loss, based upon an Agency request. When requested, we coordinate the field work testing of these metrics for an effective fiber metrics review. For the data (Frame Relay (FR)/ATM; IP/MPLS networks), Qwest deployed a set of network probes that connect across the IP/MPLS cloud and measure the network from an end-device perspective. The probes are deployed in all TeraPOPs and provide a full mesh view of all of the KPI metrics listed in Figure 3.2.4-2. They are assessed on an individual site or site-pair basis where applicable. This data is used to ensure all customer data network SLAs are systematically being supported by the network. Additionally, key network infrastructure interfaces (aggregation ports/network-to-network interfaces and ATM trunk ports) are monitored for packet/cell loss (including errors and discards) and availability, ensuring that no customer SLA issues are traceable to key network infrastructure ports.

Qwest IP-supported products use BRIX, Firehunter, and Service Level Availability Processor (SLAP) to capture data to calculate edge-based availability, CPE-based availability, latency, jitter, packet delivery rate, availability, and VoIP mean opinion scores. We use the interface-level monitoring tool Concord to determine interface-level and priority queue statistics of transmit/receive bytes, average utilization, average peak utilization, discard rate, and error rate. For VPN services, Qwest provides (customer edge) CE-based performance measures, including PE to CE and CE to CE measurements. These measurements are in addition to the PE to PE measurements. Probes are distributed to each POP that has PE routers and measurements are taken from the probes to customer CE devices. This service requires access from the probes to the customer CE devices. It is, therefore, not enabled unless specifically ordered by the customer. The Qwest ATM/Frame network uses Lucent BulkStats, NavisCore, and SLAP to get Permanent Virtual Circuit (PVC) latency (data delivery rate, port SLA availability); PVC level bi-directional statistics per class of service (transmit/receive bytes/cells, transmit discards); and port-level statistics (average and average peak transmit/receive utilization and discard rates, transmit error rate).

Individual voice services leverage multiple NEs to provide a single service to the customer. Because of this integration, voice test and certification require these same elements, as well as interconnectivity and interaction in a lab environment. Qwest certifies all voice services and products across two interconnected Integration and Test Facilities (ITF). This includes all voice, combined, toll-free services, VoIP, and IP telephony services. Qwest maintains a reproduction of the field environment in the lab to test and certify these services. Figure 3.2.4-3 lists some of the major NEs contained in the test facilities. Figure 3.2.4-3.

The test facilities incorporate all major elements of the VS. We develop test strategies and plans based on product and customer requirements and execute those plans to determine the conformance and quality of the product prior to live network implementation. Qwest performs first verification office testing on any new major voice switch loads. Where KPI and AQL compliance are identified, Qwest incorporates those measurements into test plans. Qwest maintains a central data repository for key network performance information. These performance indicators are generated by a combination of system-specific statistics (for example, call attempts generated by the SSPs), monitoring tools and call detail collection. Logs and traps are generated by the SSP, signaling transfer points, and SCPs, and are sent to the network monitoring team for instant responses. Data is analyzed, formatted, and sent to operations, engineering, and planning for proactive network enhancement and capacity planning. Common metrics that are collected are shown in Figure 3.2.4-4.

In addition to the KPIs listed above, we collect performance indicators including: • Average CPU utilization • CPU high water marks • Link utilization • Memory utilization • Busy hour call attempts • Call attempts by trunk group • Call blockage by trunk group • Overflow counts by trunk group • SCP time-outs • SS7 link failures Qwest VoIP and IP telephony services are put through the same rigorous testing processes we use to certify legacy voice services and products. Qwest maintains a test environment based on the live network architecture for VoIP and IP telephony. This includes Sonus OSP switch complexes, Acme SBCs, and Sylantro and IPUnity application servers. This VoIP ITF also connects into the legacy voice ITF for integration testing into the PSTN. For VoIP, standard IP measurement tools are used to measure the common IP KPIs, such as delay, packet loss, and jitter, as well as mean opinion score.

These incremental parameters are measured using specialized equipment such as BRIX and Agilent NGN systems where a call path is monitored from a network availability perspective. Utilizing the Brix and Agilent tools, Qwest is able to provide proactive management alerts to our network management centers when problems are identified—and provide passive management techniques—to quickly identify and perform issue isolation to support prompt resolution. This combined approach enables Qwest to reduce increased mean time between failures, effectively supporting our world-class network operation. To field test our wireless network, the Qwest Team has an ongoing process of collecting drive test data. During these drives, signal strength, coverage, and overall customer call and data quality are evaluated for each network area under study. We then use a weighting scheme to normalize the data and evaluate each of its markets, not only from a network performance perspective, but in comparison to the other operating carriers. In addition to field testing, Qwest maintains a wireless ITF that is connected to our supplier’s (Sprint) integration facility in Overland Park, KS. This environment is used to test handsets, new features and other network capabilities prior to deployment. 3.2.5 Approach to Ensure the Quality of Time-Sensitive Traffic (L.34.1.3.2(e)) All of Qwest’s data networking solutions provide proven, industry-standard methods to ensure the quality of time sensitive traffic. Our network engineering and capacity planning ensure our ability to meet the challenge of voice transport. Qwest uses VoIP switches connected via our MPLS network to handle over 2.5 billion minutes of PSTN traffic every month, indistinguishable from traditional TDM-based switches.

Qwest has best-in-class technical solutions and implementations of QoS mechanisms for both our Integrated ATM/FR network and our IP/MPLS network. Our homogeneous integrated ATM/FR network enables our customers to pre-assign applications to service classes for virtual circuits. For ATM these are: • Constant Bit Rate (CBR) • Variable Bit Rate-real time (VBR-rt) • Variable Bit Rate-non real time (VBR-nrt) • Unspecified Bit Rate (UBR) For Frame Relay these are: • Variable Frame Rate - real time (VFR-rt) • Variable Frame Rate - non-real time (VFR-nrt) • Unspecified Frame Rate (UFR) In general, voice is assigned ATM, CBR, or VBR-rt. Video is assigned VBR-rt and other data traffic could be assigned UBR. The Qwest network completely conforms to ATM and FR standards with the QoS enabled on a per-virtual circuit basis end-to-end and strictly adheres to ATM and FR traffic contracts. For both ATM and FR, the Qwest network supports a virtual guarantee of cell or packet delivery using CBR, VBR-rt, and VFR-nrt. With the network acting as a nearly perfect channel for these service classes, IP packet delivery for VoIP or video conferencing (for example, H.323) is correspondingly very high (that is, packet loss is less than 0.05 percent). Since the traffic contract is obeyed end-to- end, no other traffic on the network can interfere with the minimum data rate in the virtual circuit’s traffic contract parameters. Combined with the capacity planning described in Section 3.2.3, even failures of core ATM switches or backbone circuits will not reduce the network capacity to a point where it impacts customers’ minimum traffic contract parameters.

Traditional IP networks have evolved around “best effort” service and typically have not provided guarantees for key performance criteria. The need to support real-time services on IP networks has driven the development of IP prioritization and queuing mechanisms as well as MPLS technology. The Qwest network is engineered to enable QoS to prioritize certain types of traffic over other types of traffic. As described in Section 3.2.3, Qwest’s MPLS network supports the ability to prioritize LSPs. This means that the VoIP traffic has a higher priority than VPN or Internet traffic. Figure 3.2.5-1, as shown below, highlights the quality of service enabled by Qwest’s converged IP MPLS. Qwest’s IP MPLS network employs standards-based MPLS and IP-based QoS mechanisms to enable high quality voice, video, and data over an IP backbone. The process of applying QoS in a network, as previously shown in Figure 3.2.5-1, consists of multiple actions, defined as follows:

• Classification: Classifies different applications based on their relative network performance needs. For example, is the point-of-service application more or less sensitive to latency, jitter, and loss than the VoIP application? • Marking: Marked packets belonging to specific applications are classified so they may be recognized. For example, setting the Internet Protocol Precedence or DiffServ Code Point (DSCP) bits. • Policing: Packets determined to be out of profile (that is, not conforming to the QoS policy) are either dropped or re-marked into lower priority packets (for example, rate-limiting). • Shaping: Out-of-profile packets may also be buffered and shaped to conform to the configured QoS policy. • Queuing: Scheduler resources are allocated to different classes (or queues) so traffic may be serviced (for example, last in, first out; first in, first out; weighted fair queuing; and low latency queuing). For our IP services, this includes the prioritization of VoIP over MPLS VPN and MPLS VPN over commodity traffic. MPLS VPN customers have four customizable classes of service. Qwest offers two options with QoS, high priority and strict priority. In high priority queuing, the scheduler resources are allocated to each queue based on a predetermined fraction of total available bandwidth. This method is recommended for applications that require a minimum assurance of bandwidth availability. Therefore, with a 30/30/30/10 template, all queues are guaranteed their respective percentages of bandwidth. With strict priority queuing, the scheduler is more interested in serving traffic in the Priority 1 queue, maybe even at the expense of the other queues (that is, it is discriminatory). This method is suitable for low latency, real-time applications such as voice and high-quality video. With strict priority queuing on the ATM or FR access method, the scheduler can starve out other queues by exclusively serving the Priority 1 queue—even

though the selected template might be 30/25/35/10. If the SED does not police or shape the Priority 1 traffic to 30 percent, it is possible that other queues will be denied their allocated scheduler resources. Strict priority queuing is recommended for those applications that are extremely latency sensitive, such as VoIP. Figure 3.2.5-2, shown below, describes how Agencies can segment and prioritize traffic. In addition to the two different queuing methods—high priority queuing and strict priority queuing—Qwest IP services offer customers multiple QoS templates from which to choose. Figure 3.2.5-2, previously referenced, shows a typical MPLS- based VPN providing support for video and other applications. If all the sites are connected via T-1s, then without QoS, the video IP packets in general will be

dropped as often as other packets if the traffic flow into the destination site in the figure exceeds the capacity of the T-1. This causes significant degradation of the video quality. To ensure that each application gets its required bandwidth, Qwest will implement the following processes which are currently supported on our network: • Each CE router would prioritize the traffic that enters the Qwest IP network. This ensures that congestion at the Agency location does not interfere with the transfer of time-sensitive traffic. In particular, strict queuing with a bandwidth guarantee for Priority 1 (video) traffic would be implemented. • The Qwest IP network maintains the priority through the core network as well as protection of our MPLS, VPN, and VoIP traffic against impacts from other networks. • The Agency selects a prioritization template that is enforced on the Qwest egress (MPLS PE) so that packets marked as Priority 1 are forwarded first, and that sufficient bandwidth is allocated to meet the application’s requirements. These QoS actions ensure that low-latency, real-time applications, such as voice, can share the same access lines and core with non-real-time data applications. Our convergence approach means that Qwest data services will migrate to a common IP/MPLS network, so we can easily plan and identify any QoS issues. As described in Section 3.2.3, Qwest’s backbone and access bandwidth planning methodology ensures that there is sufficient bandwidth to meet our customer’s full port-limited capability, even in the event of core router failure or an access router or backbone trunk failure.
