AT&T Managed Internet Service

AT&T MIS provides you with access to the AT&T IP Backbone at speeds ranging from 56 Kbps to 6 Mbps (NxT1). Not all speeds are available in all areas or via all "Access Methods" described below. AT&T provides access service points at more than 600 ACCUNET points of presence (POPs) in the United States. AT&T personnel coordinate the provisioning of the local access circuit for you.

• Digital Private Line: Private Line connections to the AT&T IP Backbone are available at speeds ranging from 56 Kbps - 6 Mbps (NxT1).
• NxT1 (N by T1): NxT1 Access uses a combination of software and hardware components to provide you with greater bandwidth by automatically load balancing traffic over multiple T1 links. Packets are sent across multiple T1s, effectively performing as a single larger circuit. NxT1 helps to optimize network performance and scalability for networks with large and dynamic traffic patterns such as networks characterized by intensive web-based applications or interactive sessions. NxT1 Access is available for two to four T1s of capacity (3 Mbps, 4.5 Mbps and 6 Mbps). This offer is appropriate for customers seeking greater bandwidth without having to purchase local T3 facilities. A Tiered T3 is available should you expect growth beyond 6 Mbps.

NxT1 effectively bundles individual T1 connections through the use of per-packet load balancing on the combined circuits to take advantage of the total bandwidth of the multiple circuits. With NxT1 Access, if one T1 fails, traffic will be shifted to the T1s that continue to function normally.

AT&T MIS with Managed Router service type is defined by this standard feature. The Customer Premises Equipment includes a router, Channel Service Unit/Data Service Unit (CSU/DSU) and a diagnostic modem for out-of-band testing. All CPE supplied by AT&T is pre-configured by AT&T and includes Advanced Replacement Next Business Day (ARNBD) support. You cannot purchase the CPE. All equipment is owned by AT&T, can be used for MIS only, and must be returned at termination of the service. The CPE includes the following features and requirements:

• MIS customers with a T1 SINA MIS Access Port have two options:
  • Provide and manage a T1.5 multiplexer or a CSU/DSU with drop-and-insert capability
  • Have this component provided by AT&T.
• MIS customers with a Channelized T3 MIS Access Port must provide a M28 Multiplexer on their premises, as well as have the T3 provisioned with a M28 at the Central Office.
• All customers are required to supply a dedicated POTS line to be used only for out-of-band testing

This standard feature is available with the AT&T MIS with Managed Router service type only. You assign full management and operational control (including passwords) of the CPE to AT&T. AT&T technicians work with your designated point-of-contact to diagnose failures and determine if equipment should be replaced or repaired. If replacement is required, equipment is generally replaced by the next business day. Customers with Integrated Access (T1 SINA or Channelized T3) arrangements who choose to supply their own CSU/DSU or multiplexer are responsible for its management and maintenance.

This standard feature is available with the AT&T MIS with Managed Router service type only. AT&T oversees the implementation and maintenance of packet filtering tables in your router for added security. Packet filtering is a useful component of a comprehensive security plan. It helps prevent unauthorized access to your internal network, and controls authorized users' access to customer-specified Internet sites. AT&T engineers work with you to define a customized filtering plan and, at your request, make changes to it.

NetNews can be thought of as a gigantic electronic bulletin board system in which articles are posted and responded to according to topic. Currently there are thousands of these topics which are found online on bulletin boards called newsgroups.

As an AT&T MIS customer, you are given access to all NetNews articles and newsgroups. Additionally, you may respond to or create articles of your own for others to read. You have the option of selecting specific newsgroups and/or hierarchies of newsgroups.

To take advantage of this service you purchase, install, configure and manage a network news server to which AT&T provides a standard Network News Transfer Protocol (NNTP) Newsfeed. AT&T does not censor or screen objectionable or unwanted news, nor does it limit the number of news groups requested, but AT&T can add or delete news groups at the your request during normal business hours. The central news servers are monitored by AT&T around the clock.

This component provides you with online access to traffic summary reports which track access line use as a percentage of the available bandwidth. This comprehensive view of usage data provides you with a valuable tool to effectively monitor and manage their Internet bandwidth use and plan for future upgrades. Network Usage Reports are available 24 hours a day, seven days a week except during maintenance. You can access Network Usage Reports through a website with various security features. Secure Socket Layer (SSL) technology is used to protect your data from unauthorized users. All of your data is password protected.

Flat Rate Billing
With Flat Rate Billing, you contract for a stated bandwidth and pay a set monthly fee for the term of the contract. Flat Rate Billing's level charge simplifies a business's budgeting and planning process.

Burstable Billing Method
With Burstable Billing, you get a full dedicated access circuit, but only pay for actual sustained bandwidth usage-not the full line rate. Burstable Billing customers can "burst" up to the full capacity of the pipe when needed.

The following support features are designed to make your implementation as easy as possible. Each AT&T MIS customer will have online access to the MIS Implementation Planner. This planner provides detailed information about the installation and use of MIS. An AT&T Provisioning Technical Engineer (PTE) works with you to prepare for providing and initiating service.

• Service Activation: AT&T MIS customers are charged a Service Activation fee which includes the technical interview with the PTE, access line coordination, DNS registration and service testing. This also includes equipment configuration for AT&T MIS with Managed Router customers.
• Tele-installation: Tele-installation is standard for customers purchasing MIS online. With tele-installation, customers are responsible for unpacking and connecting the CPE, but telephone assistance from AT&T is available if needed.
• Site Planning and Preparation: AT&T helps you prepare for AT&T MIS installation by providing site information to your designated point of contact and by registering your network numbers, domain names, and routing information. You must provide space and power for the dedicated router and other premises equipment, an attachment to the customer's internal network, at least one computer with TCP/IP support, and a dedicated POTS line for the out-of-band diagnostic modem. This support service is not available to customers who provide their own CPE.
• Access Circuit Provisioning: AT&T will order and install, on your behalf, the AT&T Private Line circuit, Frame Relay PVC, or ATM PVC necessary for delivery of AT&T MIS. AT&T will arrange for termination of the circuit in proximity to the planned location of the premises equipment. Any necessary inside wiring changes are your responsibility.
• Cooperative Testing: Customer Care will conduct cooperative testing of your site to ensure that your on-site router can successfully communicate over AT&T MIS. The cooperative test verifies the proper operation of the on-site equipment, the local access facility, and the access infrastructure. AT&T Managed Internet Service activates billing after AT&T has completed their processes for providing service.

AT&T Managed Internet Service is supported by AT&T's Customer Care organization and the Network Operations Center (NOC). Through both organizations, the AT&T MIS technical support staff provides valuable network operations services, described below.

• Network Monitoring: AT&T MIS assures the highest network performance through careful IP network management and the industry-acclaimed performance of the AT&T network. The IP network is monitored by the NOC using SNMP-based software. The software is used in combination with other essential tools to monitor non-SNMP equipment, domain name servers, NNTP news feeds, and other network services. The status of the network is continually reported on a display monitored around the clock. All changes in the IP network status are logged, giving the NOC the ability to evaluate staff responsiveness and network availability. In addition to the IP network, the underlying transport network is monitored by AT&T Transport Centers 24 hours a day, 365 days a year.
• Customer Premises Equipment Monitoring, Maintenance and Management: AT&T's technical staff is responsible for maintaining dedicated premises equipment for MIS customers that have their CPE provided by AT&T as part of their service. Technical Support Engineers work with your designated point-of-contact to diagnose failures and to determine if equipment should be replaced or repaired. Equipment repair, if required, is performed by your central point of contact with telephone assistance, if needed, from Customer Care. If replacement is required, equipment is replaced by the next business day. This network operation service is not available to those customers electing to provide their own CPE.

AT&T Managed Internet Service includes all of the technical support services essential for optimal use of the service. Customer Care only supports and accepts calls from the customer and does not accept calls, provide assistance, or interface in any manner with parties other than the customer, regardless of whether or not such parties have purchased services from the customer. Customer care will, however, accept calls from end- customers of resellers who are connected directly to the AT&T IP backbone. The technical support services are:

• Software and Configuration Support: For MIS customers that have their CPE provided by AT&T as part of their service, the AT&T MIS Technical Staff coordinates software updates and configuration changes as required for the router and CSU/DSU. Notice of software changes is made to your central point of contact, and every effort is made to perform maintenance during off-hours. This technical support service is not available to those customers electing to provide their own CPE.
• 24-Hour Hotline: The AT&T MIS hotline is staffed around the clock. All calls to the hotline are directed to the appropriate technician through a touch-tone menu system. Customer Care can be reached at 1-888-613-6330 or via email at RM- awmis@ems.att.com
• Trouble Ticket System: With the support of the NOC, the AT&T Customer Care organization tracks problems from initial report to satisfactory resolution through the Network Operations Trouble Ticket System. While the technical staff is resolving any given problem, its current status is reflected in the Trouble Ticket System. If needed, the system's electronic mail and fax interfaces facilitate the electronic distribution of trouble ticket reports to your technical contact.
• Fault Isolation and Problem Resolution: Fault isolation involves coordination among network operators and technicians, staff at the affected site, and other vendors. Depending on the specific technologies used, the process may involve testing equipment, reconfiguring routers, or diagnosing communication link problems.
• Security Procedures: Security procedures for AT&T MIS help keep you informed of known and suspected security breaches. AT&T reviews information about security problems regularly and distributes it to your sites as necessary. Customer that have their CPE provided by AT&T as part of their service may authorize several contacts to request site disconnection or reconnection as necessary.

The following electronic servicing capabilities are available for your use through the AT&T BusinessDirect. The electronic features listed below are available to AT&T MIS customers of record only. The AT&T BusinessDirect platform is accessible to customers by visiting https://www.businessdirect.att.com/portal/smallbusiness/index.jsp.

• Customer Care Website: The Customer Care Website is the default home page for MIS customers. It provides an overview of the available services and features, access to all MIS tools, current network status, technical and implementation- related FAQs, service change forms, invoice samples, contact information, and a "What's New" section for the latest service-related information.
• Online Bill Inquiry System: The Online Billing Inquiry System allows you to analyze and download their current and 12-month archived invoice.
• DNS Provisioning Tool (DPT): DPT gives MIS customers with AT&T-provided primary or secondary DNS a way to view, add, delete, or update their DNS records and add new Domains quickly and easily.
• Online Network Usage Reports: Customers can access an AT&T-provided website to see and use Online Network Usage Reports. With these, you can view inbound, outbound, and average network traffic in graphical form and downloadable tabular form.

AT&T Managed Internet Service is based on AT&T's IP backbone and the AT&T core network, the world's most reliable network. The AT&T IP backbone is designed and engineered with the purpose of attaining the highest possible levels of reliability and performance. It offers AT&T MIS customers a number of built-in features for exceptional or incomparable advantages, including:

• Industry Leading Reliability: Backed by Service Level Agreements, the Target availability for the AT&T IP backbone is an industry leading 100%. The backbone network is designed with no single point of failure in the core architecture. All backbone nodes are located in secured AT&T central offices. At the present time 24 cities in the U.S. are connected via multiple OC48/OC192 links, with 80 smaller cities connected to the backbone with multiple OC3s. AT&T's IP backbone has been designed with multiple "rings" for alternate path re-routing and with no single point of failure in the core IP network. Each Backbone node is connected to a minimum of two other nodes. Backbone routers are installed in pairs, with longhaul backbone facilities divided among the backbone routers to avoid single points of failure and ensure network continuity even in the event of a facility failure. Connections between all backbone routers are Packet over SONET for high performance and cost-effectiveness. All routers are deployed in a redundant fashion, with redundant power supplies and redundant processors. There is no single point of failure in the core backbone architecture.
• Outstanding Performance: The target average cross-country round-trip delay of the AT&T IP Backbone is 37 ms. The AT&T IP backbone delivers more than 99.95% of data due to the careful management of capacity. Actual network performance, updated every 15 minutes, is posted on the public Internet at the AT&T IP Network Performance Web site.
• Superior Security: All nodes within the AT&T IP backbone are located in AT&T owned and maintained secure facilities, which are guarded and manned 24x7 and only accessible to authorized personnel. All nodes are protected by un-interruptible power sources, including both battery backup and emergency diesel generators. In addition a robust disaster recovery scheme is tested regularly to ensure that all components work in the event of a power failure. In addition to physical security of the nodes, AT&T has taken many steps to secure the network elements within the AT&T IP backbone in order to ensure reliable service. For example, all of the general, non-routing functions in the core routers are disabled. This both enhances the performance of the network and reduces the potential of a hacker using general router capabilities to illicitly access the system. In addition to these security measures, AT&T's IP backbone security is enhanced through the use of IP Source Address Filtering. AT&T has installed source address filters on our backbone routers at two places--1) at all dedicated customer connections to this network and 2) at all entrances from the public Internet. At all dedicated retail customer connections, the source address of all inbound packets is examined to make sure it matches the IP address which we expect to find on those packets; if the source address doesn't match, the packets are discarded. This is a key method by which ISPs can enhance the security of their networks since hackers typically try to hijack someone else's IP address in order to hide their identity while they are doing their mischief. Inbound from the public Internet, this same filtering technique is applied to inbound packets; in this case packets are discarded which contain IP addresses from a special "reserved" portion of AT&T's Class A address. This "reserved" IP address area is used for customers of AT&T's VPNS. This is an extra security step which was recommended by the Carnegie-Mellon Computer Emergency Response Team (CERT). This 'Spoof-Proofing' is an AT&T value-added service that is inherent in the design of our architecture. Wholesale and downstream providers are required to use this same security technique on their downstream networks in order to connect to the AT&T IP Backbone. This enables AT&T to say that the AT&T IP Backbone is RFC2267 compliant.
• Peering: Peering refers to an agreement AT&T makes with another ISP to interconnect in order to exchange routing information and Internet traffic between the ISPs' Internet Networks. AT&T's peering architecture is focused on maintaining excellent performance to anywhere on the Internet through routing over 90% of all Internet-bound traffic via private peering links and carefully managing capacity on these links so they are never more than 65% utilized on average. In general, AT&T always peers with ISPs at a minimum of three locations which are geographically dispersed; this ensures that in the event of a link failure, traffic can be re-routed via an alternate connection. AT&T has led in the industry in the installation of high-bandwidth private peering links and presently has multiple OC12 private peering links in place, as well as the industry's first OC48 peering link.
• Maximum Control: The IP backbone is monitored and maintained through AT&T's state-of-the-art Network Control Center (NCC). The NCC is connected to the rest of the network by two physically diverse facility feeds. A comprehensive test-bed network environment is used for controlled introduction of new features and capabilities to maximize network performance and reliability even as the backbone is being upgraded.
• Non-Traditional Space: AT&T Business Services has deployed Remote Gigabit Access Routers (RGARs) in "non-traditional" facilities. Non-traditional means a facility neither owned nor managed by AT&T.

Domain names are the words, such as XYZCompany.com, that represent the actual numerical IP address, [e.g. 14.127.18.139] used to navigate the Internet. A Domain Name System (DNS) is required for dedicated Internet access, regardless of whether it is established and administered by you or by AT&T. AT&T MIS includes:

• Up to 15 primary DNS zones with a maximum of 150 Kilobytes of Primary zone data
• Up to 15 secondary DNS zones with a maximum of 150 Kilobytes of Secondary zone data

Customers who need more than the above maximums may purchase the Additional DNS option.

Prior to initiation of AT&T MIS, AT&T engineers register your domain names on your behalf and serve as the primary technical contact. You're then responsible for all domain registration fees related to provisioning and use of domain names. You may choose to establish your own primary DNS in which case AT&T will provide/administer secondary DNS only, if requested. Once your DNS has been established, you self-administer your DNS for all existing zones using the web-based DNS Provisioning Tool (DPT). DPT is available 24 hours a day, seven days a week. You can view, add, delete or update your DNS records and add new domains quickly and easily, rather than submitting these requests to the MIS Customer Care organization. However, for IP block assignments, you will need to submit requests through Customer Care. This component is not available to downstream providers (resellers); it is only available to Customer and is not available to third parties given access to MIS by Customer, regardless of whether such parties have purchased services from Customer.

AT&T also operates "resolving" or "caching" DNS servers that can be used for domain name lookups, e.g. www.yahoo.com, by Customer's in-house systems (PCs, mail servers, etc) connected to MIS. This service is only available to Customers who do not have their own in-house DNS server(s). Customers with their own DNS servers should use those systems for this function. This service is not available to downstream providers (resellers) or third parties given access to MIS by Customer. AT&T reserves the right to block access to its resolving DNS servers by Customers who do not meet these requirements.

Frame Relay Service
Frame Relay connections to the AT&T IP Backbone are available at speeds ranging from 64 Kbps -1.5 Mbps. Customers who wish to connect to the AT&T IP Backbone using AT&T Frame Relay Service have two options.

• Existing AT&T Frame Relay customers or those who order the Frame Port separately from AT&T MIS receive a permanent virtual circuit (PVC) to the AT&T IP Backbone as part of AT&T MIS at no additional charge. Please note: the service type AT&T MIS with Managed Router is not available with a non-dedicated Frame Relay port.
  
  CAUTION: An inherent security risk exists with this choice since AT&T MIS and Frame Relay traffic from a single Frame Port can only terminate on a single customer router.
• Customers without existing AT&T Frame Relay Service can contract for a Frame Relay Port and PVC to the AT&T IP Backbone as part of their AT&T MIS contract at no additional charge. The Frame Port is dedicated to the MIS connection and is not configured to support any services other than MIS. Local access provisioning options are the same as with MIS Private Line access.

ATM Service
AT&T MIS via ATM is currently supported in ten Backbone Nodes: New York, Washington DC, San Francisco, Dallas, Chicago, Atlanta, Los Angeles, Denver, Seattle and St. Louis. ATM connections to the AT&T IP Backbone are available at speeds ranging from 2 to 60 Mbps.

Customers who wish to connect to the AT&T IP Backbone using AT&T ATM Service to transport AT&T MIS have two options:

• Existing AT&T ATM customers can order and receive a PVC to the AT&T IP Backbone as part of their MIS at no additional charge.
  
  NOTE: AT&T MIS and ATM traffic must be directed to separate routers on your premises using a customer provided ATM switch to minimize a security risk to your existing private ATM network.
• Customers without existing AT&T ATM Service can order an ATM Port and PVC to the AT&T IP Backbone as part of AT&T MIS at no additional charge. A single contract is signed for MIS service. No separate contract for the ATM Port is necessary. The ATM is dedicated to the MIS connection and is not configured to support any services other than MIS. Local access provisioning options are the same as with MIS Private Line access.

With ATM service, PVCs are supported at the following speeds:

• T3: 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35 and 40 Mbps.
• OC3: 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45 and 60 Mbps
  
  Note: SINGLE PVC orders between 2-30 Mbps requires you to have an existing ATM OC3 port.

Multiple PVCs are supported within the following guidelines:

• Flat rate billing only. Burstable, Hi Cap Flex, and Shadow billing are NOT AVAILABLE.
• MIS with Managed Router: supports up to 4 PVCs with a cumulative speed of 35 Mbps for T3 and 120 Mbps for OC3.
• MIS (with Customer managed router): supports up to 10 PVCs with a cumulative speed of 35 Mbps for T3 and 120 Mbps for OC3.

Integrated Access (T1 SINA or Channelized T3)
Customers choose Integrated Access when you want to split circuits between applications (such as voice and data) or to allocate channels to multiple AT&T Services. You must make an available connection on the AT&T POP (M24 or M28) and the CSU/DSU interface of equal bandwidth to the requested AT&T MIS Port.

• For T1 SINA and AT&T MIS with Managed Router you need an adapter and associated cable which provides the connection between your PBX and the associated port on the back of the CSU/DSU. You have the option of providing and managing the T1 multiplexer (CSU/DSU) or you may have AT&T provide and manage it. If you elect to have the CSU/DSU provided by AT&T, the service demarcation point is the DB15 port on the CSU/DSU. The AT&T MIS router will only be allowed to handle MIS Access Port traffic. Non-MIS Access Port traffic will not be allowed to terminate on the AT&T MIS Router.
• AT&T MIS customers with Channelized T3 must provide and manage the T3 (M28) Multiplexer on your premises as well as ensure that the T3 is provisioned with a M28 in the AT&T POP. The individual T1s in a Channelized T3 arrangement can be used for AT&T MIS to provide either a single T1.5 Private Line connection or an NxT1 (3 Mbps, 4.5 Mbps, or 6 Mbps) connection.

Ethernet Access AT&T MIS supports the following Ethernet Access customer interfaces:

• 10-Base-T (10 Mbps Ethernet over Copper)
• 100-Base-T (100 Mbps Ethernet over Copper)
• 100-Base-Fx (100 Mbps Ethernet over Fiber)
• 1000-Base-Sx 2 (1000 Mbps Ethernet over Fiber)

Non-Traditional Space Locations where AT&T MIS has a presence:

• Equinix carrier Neutral Co-location Facilities in
  • Ashburn, VA
  • Chicago,IL
  • Dallas, TX
  • Los Angeles, CA
  • Newark, NJ
  • San Jose, CA
  • Secaucus, NJ
• Other Carrier Neutral Co-location Facilities
  • Tera NAP in Miami, FL
  • One Wilshire Place in Los Angeles, CA
  • Westin Building in Seattle, WA
  Additional POP locations are available in most major cities.

Hi Cap Flex Billing Method
As with Burstable Billing, Hi Cap Flex Billing customers are provisioned with a fully dedicated access circuit, but only pay for actual sustained bandwidth usage-not the full line rate. It differs from the Burstable Billing option in that you select a minimum monthly bandwidth commitment and then pay an additional fee for sustained usage above the minimum commitment. MIS Hi Cap Flex Billing customers can "burst" up to the full capacity of the pipe when needed.

Shadow Billing Method
Shadow Billing is available for the redundant dedicated access connection only for customers who have selected either Backbone Node Redundancy or Access Router Redundancy (single customer site configurations only). Shadow Billing is not available for the primary access connection. Shadow Billing uses a modified Burstable Billing pricing structure, with minimum billing of 56 Kbps. For AT&T-Managed Router customers, traffic is routed over a single, primary link. The second, redundant link remains unused, providing a backup in case the primary link fails. For customers electing to manage their own router, you will be responsible for managing the traffic flow over the primary and redundant links.

The following support features are designed to make your implementation as easy as possible. Each AT&T MIS customer will have online access to the MIS Implementation Planner. This planner provides detailed information about the installation and use of MIS. An AT&T Provisioning Technical Engineer (PTE) works with you to prepare for providing and initiating service.

• Service Activation: AT&T MIS customers are charged a Service Activation fee which includes the technical interview with the PTE, access line coordination, DNS registration and service testing. This also includes equipment configuration for AT&T MIS with Managed Router customers.
• On-site Implementation: MIS with Managed Router customers have the option of receiving on-site installation support. With on-site installation, an authorized AT&T Service Technician unpacks, connects, and tests the CPE and completes the cooperative testing with the NOC.
• Site Planning and Preparation: AT&T helps you prepare for AT&T MIS installation by providing site information to your designated point of contact and by registering your network numbers, domain names, and routing information. You must provide space and power for the dedicated router and other premises equipment, an attachment to the customer's internal network, at least one computer with TCP/IP support, and a dedicated POTS line for the out-of-band diagnostic modem. This support service is not available to customers who provide their own CPE.
• Access Circuit Provisioning: AT&T will order and install, on your behalf, the AT&T Private Line circuit, Frame Relay PVC, or ATM PVC necessary for delivery of AT&T MIS. AT&T will arrange for termination of the circuit in proximity to the planned location of the premises equipment. Any necessary inside wiring changes are your responsibility.
• Cooperative Testing: Customer Care will conduct cooperative testing of your site to ensure that your on-site router can successfully communicate over AT&T MIS. The cooperative test verifies the proper operation of the on-site equipment, the local access facility, and the access infrastructure. AT&T Managed Internet Service activates billing after AT&T has completed their processes for providing service.

This option, implemented on your access and egress links, allows you to prioritize your traffic based upon the type of traffic or application and your performance requirements. Without this option, AT&T MIS offers best effort treatment, which means it doesn't matter what type of traffic you send/receive as it will all be treated equally.

Four (4) Classes of Service (CoS) are available: Real-time and three (3) Data Classes (High-grade data, Medium-grade data, and Low-grade data).

This option allows you to request the AT&T IP Backbone Node where their MIS connection will terminate. Normally, the MIS connection terminates on the Backbone Node closest to your site.

CPE Redundancy Option provides a "Cold Standby" CPE configuration. The Cold Standby provides customers with a fully configured and tested AT&T MIS CPE router and CSU/DSU housed on the customer's premises. If the router and/or CSU/DSU fail, the customer's central point of contact replaces the non-working CPE. AT&T Customer Care provides customer assistance during the CPE changeover. This option is available only to MIS customers who elect to lease their CPE from AT&T.

The IP arena is rapidly evolving into a market where customers of dedicated hosting and/or co-location facilities are demanding direct access to multiple backbone providers for redundancy and load balancing. To meet this market need, AT&T Business Services has started the deployment of Remote Gigabit Access Routers (RGARs) in "non-traditional" facilities. A Non-traditional facility is one that is not owned/managed by AT&T e.g. non-AT&T data centers. These RGARs extend access to the AT&T IP Backbone from non-AT&T data and co-location centers. At the present time, we have deployed RGARs in Equinix facilities, the Westin Building (located in Seattle, Washington), and One Whilshire Place (located in Los Angeles, California). We will expand this offer as we deploy RGARs in additional co-location centers.

AT&T MIS with NCS provides a physical presence within an AT&T Central Office (CO) and a direct connection to the AT&T IP Backbone. AT&T provides a preinstalled rack with power supply within the CO secure building. The customer provides and maintains the router, cabling, and other equipment necessary to maintain the service. Because of the direct connection to the Backbone, the MIS Local Access Combination Option is not available or required. You are charged a NCS monthly fee called a Site License Fee. It covers the monthly fee for the space, environment, power and security in the Central Office.

AT&T Managed Internet Service with Voice over IP (MIS with VoIP) lets you use your MIS data access connection for voice and fax. VoIP uses idle bandwidth on a MIS connection to deliver cheaper outbound voice calls to anywhere in the world. Voice calls are converted to IP packets and transported over the AT&T IP Backbone. Learn more

AT&T Managed Internet Service Multi-Line is an option that lets you order multiple circuits on one order with one contract, either for your own use or to resell. This option permits an end-customer who is not the AT&T customer of record to be connected to the AT&T IP Backbone and receive tier-two and tier-three customer care directly from AT&T. Invoices are designed so that circuits can be grouped by end-customer with circuit detail included, making it easier for the customer of record to bill their downstream end-customers.

This option provides high speed circuits into the AT&T IP Backbone coupled with an enhanced customer care model where your circuits are viewed as one virtual network by our maintenance center. AT&T Managed IP Network Service (MIPNS) is designed for Service Providers, and certain Enterprise customers, seeking to aggregate their own traffic in a given region, and then leverage the AT&T IP Backbone for inter-regional traffic using an array of access methods. In effect, you utilize the AT&T IP Backbone to sell AT&T services as your own services to your end-user customer (AT&T Enterprise Hosting Services are available now; future services will include VoIP and provider-class VPN). MIPNS can support a single AS (Autonomous System) Number for your entire IP network. This feature is most useful to customers that wish to connect your regional networks together with one AS number. MIPNS customers will be assigned a Project Implementation Manager (PIM) who will be responsible for overseeing the implementation of all circuits. You will receive enhanced customer care support from agents that will be familiar with their specific account and able to address their needs promptly and efficiently. These agents, as well as the AT&T Network Care agents, will have a total view of your network circuits. The service also supports the ability of the customer to have a dedicated access router, either within the standard AT&T IP backbone configuration, on your premises, or some other configuration outside of the standard AT&T IP backbone configuration e.g. Carrier Center. At your discretion, ports on these dedicated routers can be sold as AT&T Managed Internet Service to other customers.

This option allows you to order multiple circuits on one order with one contract. You will select a minimum usage commitment for each circuit, which will then be aggregated (totaled together) to determine the total network usage commitment. A tiered pricing schedule will be developed for each opportunity. A minimum monthly commitment of 500 Mbps is required, with some exceptions if the MPLS Private Network Transport option is requested. Each month, actual sustained usage for each circuit will be determined using the same methodology used for the MIS Usage-based billing options. The actual usage for each circuit will be aggregated to determine the total actual usage across all circuits. You will then be billed based upon their pricing schedule. Invoices are designed so that circuits can be grouped by end-customer with circuit detail included, making it easier for you, the customer of record, to bill your downstream end-customers.

AT&T MIS Access Redundancy Options optimize the performance of multiple dedicated Internet circuits as well as eliminate single points of failure. Three options are available:

• Backbone Node Redundancy: With Backbone Node Redundancy a group of circuits terminate on one or two different Customer Routers (CR) and two different Access Routers (AR) located within two geographically separate AT&T IP Backbone Nodes. This option provides a logical redundant path, a redundant CR connection (if two CRs are used), a redundant AR connection and a redundant AT&T IP Backbone Node connection to help eliminate the single point of failure for the circuit, Customer Router Access Router, and the Backbone Node. The bandwidth of each link can be different. The redundant link must use a shared transport method such as ATM or Frame Relay. Standard pricing for each link is based on bandwidth, CPE LAN requirements (for MIS with Managed Router customers) and transport used. Private Line access for the redundant link and CPE memory upgrades will be supported; additional charges apply.
• Access Router Redundancy: With Access Router Redundancy a group of circuits terminate on one or two different Customer Routers (CR) and two different Access Routers (AR) within the same AT&T IP Backbone Node. This option provides a logical redundant path, a redundant CR connection (if two CRs are used), and a redundant AR connection to help eliminate the single point of failure for the circuit, Customer Router and Access Router. The bandwidth of each link can be different. Standard pricing for each link will be based on bandwidth, CPE LAN requirements (for MIS with Managed Router customers) and transport used.
• Automatic Load Balancing: With Automatic Load Balancing, a group of circuits terminate on one or two Customer Router(s) and a single Access Router for the purpose of balancing the traffic across the circuits. This option provides a logical redundant path to help eliminate the single point of failure for the circuit only. The bandwidth of each circuit within the group must be the same. Standard pricing for each link will be based on bandwidth, CPE LAN requirements (for MIS with Managed Router customers) and transport used.

Domain names are the words, such as XYZCompany.com, that represent the actual numerical IP address, [e.g. 14.127.18.139] used to navigate the Internet. A Domain Name System (DNS) is required for dedicated Internet access, regardless of whether it is established and administered by you or by AT&T. AT&T MIS includes:

• Up to 15 primary DNS zones with a maximum of 150 Kilobytes of Primary zone data per circuit
• Up to 15 secondary DNS zones with a maximum of 150 Kilobytes of Secondary zone data per circuit

Customers who need more than the above maximums may purchase the Additional DNS option.

Prior to initiation of AT&T MIS, AT&T engineers register your domain names on your behalf and serve as the primary technical contact. You're then responsible for all domain registration fees related to provisioning and use of domain names. You may choose to establish your own primary DNS in which case AT&T will provide/administer secondary DNS only, if requested. Once your DNS has been established, you self-administer your DNS for all existing zones using the web-based DNS Provisioning Tool (DPT). DPT is available 24 hours a day, seven days a week. You can view, add, delete or update your DNS records and add new domains quickly and easily, rather than submitting these requests to the MIS Customer Care organization. However, for IP block assignments, you will need to submit requests through Customer Care. This component is not available to downstream providers (resellers); it is only available to Customer and is not available to third parties given access to MIS by Customer, regardless of whether such parties have purchased services from Customer.

AT&T also operates "resolving" or "caching" DNS servers that can be used for domain name lookups, e.g. www.yahoo.com, by Customer's in-house systems (PCs, mail servers, etc) connected to MIS. This service is only available to Customers who do not have their own in-house DNS server(s). Customers with their own DNS servers should use those systems for this function. This service is not available to downstream providers (resellers) or third parties given access to MIS by Customer. AT&T reserves the right to block access to its resolving DNS servers by Customers who do not meet these requirements.
