AT&T Inc. is one of the world's largest telecommunications holding companies and is the largest in the United States. Operating globally under the AT&T brand, AT&T companies are recognized as the leading worldwide providers of IP-based communications services to business and as leading U.S. providers of high-speed DSL Internet, plus local and long distance voice services. AT&T Inc. holds a 60 percent ownership interest in Cingular Wireless, which is the largest U.S. wireless services provider with almost 60 million wireless customers.

AT&T Competitive Positioning
AT&T is a tier 1 ISP, a member of a select group of 9 of the largest ISPs that represent the true “backbone” of the Internet. Every Tier 1 provider has direct peering arrangements with the other tier 1 providers that allow traffic flow to any other point on the Internet through every other tier 1 provider, thus offering the highest reliability and redundancy plus the best performance. Generally, tier 1 providers are acknowledged to have some of the fastest backbone links, the largest geographic footprint, the most mature network operations, and the most proven network stability of any Internet ISP.

AT&T, which represents the merger of SBC, Pacific Bell, BellSouth, and AT&T, is a financially strong global organization with a history of innovation in the telecommunications industry for over 120 years.

AT&T has the widest range of data and voice products of any carrier, including business class DSL, T1 voice and data services, and higher speed services such as T3 (44 mbps) and even ultra high speed SONET fiber ring connections with speeds up to 9.9 gbps. AT&T has solid solutions for phone system connectivity using digital ISDN PRI lines, and innovative T1 services that can mix digital PBX voice services together with business-class Internet connectivity all on a single T1 circuit, which is ideal for organizations that can’t yet justify separate dedicated T1 circuits for voice and data.

Bonded Internet connections are available for companies that need more performance than a traditional T1 (1.5 mbps) can offer. You can choose full symmetrical speeds of 3.0, 4.5, and 6.0 mbps. Not only do bonded T1 connections offer increased performance, but a natural bi-product is fault tolerance against line problems. In the event that the bonded T1 lines fails, the remaining circuits continue to keep Internet traffic flowing, although at a degraded performance level.

Private point-to-point T1 services are ideal for companies that need to have tight control of their inter-office communications traffic. By deploying such point-to-point circuits, companies can fully prioritize the traffic for latency-sensitive applications, such as VoIP or video-conferencing, while allowing shared use for other traditional data applications. Such prioritization is not available with VPN links due to the shared nature of the Internet. By offering speeds in increments of 1.5 mbps, companies can scale up the needed network performance in cost-effective steps.

AT&T IP Flexible Reach allows organizations to handle local calls from multiple cities, including other states, and have them terminated in a single location. This is ideal for companies that want to have a centralized PBX to handle all voice communications for a geographically dispersed organization with multiple offices and/or telecommuters that need to have a seamless voice infrastructure. By delivering calls via VoIP technology instead of legacy TDM technologies (ISDN and T1), companies can take advantage of powerful redundancy techniques available for Internet connections to craft a fully fault-tolerant voice communications infrastructure. In addition, by leveraging VoIP delivery, easy scalability is achieved through the use of low-cost Internet lines. Such a solution is also ideal for hosting a company's entire PBX in a highly fault tolerant Internet data center.

AT&T Internet Protect is a security alerting and notification service that offers advanced information regarding potential real-time, early-stage threats such as viruses, worms, and distributed denial of service or DDoS attacks.

AT&T's Network-Based Firewall Service provides a fully-managed, secure, cost-effective solution that allows you to manage and control employee access to the Internet and prevent unauthorized access into your corporate AT&T network, without the expense of on-premise equipment.

AT&T Collocation services make an ideal complement to customers utilizing AT&T DSL and Internet connection services. AT&T has world-class data centers available for hosting customer equipment. AT&T Enterprise Hosting Services offer a rich portfolio of flexible hosting solutions to help ensure uninterrupted access and improved performance of your critical business data and applications. AT&T Enterprise Hosting Services deliver a fully integrated application and networking infrastructure to handle the simplest or the most demanding hosting requirements, simplifying and streamlining the integration of components from separate vendors.

AT&T's Virtual Private Network services gives you the advantage of VPNs without the cost of local equipment. Virtual Private Networks deliver the attributes of a private data network within a shared network infrastructure. They offer enterprise-class scalability and reach across multiple IP-based infrastructures, along with many of the enhanced performance and security characteristics traditionally found only in dedicated private environments.
