Private Line: Move Data Quickly and More Securely

Demands on today's networks are growing. Businesses are increasingly relying on high-bandwidth applications to send information and communicate with employees. Keeping your information and your network secure can be a challenge.

AT&T provides data, video and voice transmission services that are fast and efficient, with the diversity to protect your network assets.

Private line services provide:

  • Dedicated service connections
  • High transmission speeds
  • Excellent data security

Private line services can help you:

  • Maintain a competitive edge with quick access to time-critical information
  • Overcome the challenges of sending and sharing large files
  • Communicate with employees and others using streaming video, computer-aided design programs and other bandwidth-intensive applications

Low latency for high-speed transport

With scalable speeds of up to 40 gigabits per second, private line services have one of the lowest levels of latency available. This makes private line services a good choice for:

  • Financial institutions and other businesses that move vast data volumes quickly across a secure environment
  • Broadcasters that speed high-quality video feeds between locations

Smaller packets of data, such as those sent and received by security and alarm-monitoring businesses, can be moved more swiftly and cost-effectively, too.

Ease data backup

Low latency makes private line services a solid choice for increasing data protection. These scalable services can be set up between your data center and a remote site for efficient backup and storage of your critical information. Private line services can also help you quickly restore data after a disaster or other disruptive event, allowing you to get back up and running quickly.

Extensive global reach

Your business may be spread out, but private line services can help you pull everyone together. Whether your offices are across street, across state lines or overseas, private line services' dedicated point-to-point connections can move your voice, data and video traffic more securely and cost-effectively. Private line service from AT&T is available domestically and in 80 countries around the globe.

As you assess private line services for your business, here are some things to consider:

Whether your business requires high-speed access for local offices or nationwide coverage, private line services from AT&T can carry your voice, video and data traffic on a connection that fits your needs.

Is speed a competitive advantage?

If success is measured in seconds and getting to market with new ideas or information before your competitors is critical, the speed advantages of low-latency private line services may be right for you. Private line services can also be a good choice for sending time-critical data, such as brokerage-to-trading-floor communications.

Do you need a high level of data security?

Private line connections are dedicated point-to-point or multipoint services, so there are fewer opportunities for security breaches. This means your network may be less vulnerable to outside intruders.


Private line services are highly scalable and can be customized to meet unique business requirements. Data network consultants from AT&T can work with you to analyze your needs and design connections based on:

  • How much and what type of traffic you have
  • The locations between which the traffic will move
  • How often and how quickly data needs to be transmitted

Our consultants will also test complex setups in our proof-of-concept lab to help make certain your connections are ready to go once they are deployed.

Service delivery

Many private line services can be established quickly and easily. If your set up is more complex or you need very high speeds, AT&T data network consultants work with you to help ensure your connections are optimized before your service is deployed.

Customer support

The AT&T backbone network over which private lines are carried is monitored round the clock by the Network Operations Center. They respond quickly to network issues, helping to keep your applications up and running.
