  Dedicated Communication Services

Dedicated circuit of pre-subscribed bandwidth.

Dedicated Communications Services are service configuration solutions that provide fast, high-quality, secure voice and data connections for your business. With Dedicated Communications Services, you get a dedicated circuit of pre-subscribed bandwidth between two of your locations. We reserve this circuit for your exclusive use, so you can safeguard sensitive or confidential information. You can also consolidate your communications, such as voice, data, video and multimedia, over this private line.

Your private line serves as a network building block, and can securely connect a hubbed network with remote sites. It links your corporate headquarters with other offices or branches in other areas. And, with dedicated voice trunking, you can configure your private line to handle high call volume, offering more employees the benefits of secure voice and data communications.

What will it do for me?

  • Point-to-Point Service — Maximize information flow with a dedicated digital connection between two of your locations.
  • Dedicated Circuits — Always have the connection you need, whenever you need it.
  • Guaranteed Bandwidth — Choose the right solution to meet your specific requirements.
  • Quality Connections — Count on high-speed, all-digital connections at defined standard bandwidths and service qualities.
  • Affordability — Save money with economic flat-rate prices and term pricing.


A variety of AT&T private line service configurations fall into three categories based on your company's needs:

Dedicated Communications Services

  • DS0 Service — custom design your data network with a variety of speed increments from 2.4 Kbps to 64 Kbps. DS0 Service is a cost-effective, end-to-end digital service that you can configure in point-to-point and/or multi-point arrangements between sites.
  • DS1 Service (also known as T1 service) — combine voice and data traffic, link remote hosts, and increase productivity with data-intensive applications like videoconferencing at speeds up to 1.544 Mbps. You can use the entire 1.544 Mbps for single, high-bandwidth applications or you can channel your DS1 into 24 separate DS0s for multiple use.
  • DS3 Service (also known as T3 service) — consolidate your existing DS1 voice, video and data traffic with speeds at 45 Mbps (equivalent to 28 DS1 circuits, or 672 DS0 channels).
Advanced Networking Solutions Native LAN Services
  • GigaMAN® — provides a fiber-based, point-to-point Ethernet interconnection service to link LANs within a single metropolitan area via dedicated, single-mode fibers at up to 1.25-gigabit-per-second speeds.
  • FibreMAN(SM) — provides a dedicated, point-to-point, full duplex private line service over fiber at speeds up to 2 Gbps.


Dedicated Communications Services are provided by AT&T Arkansas, AT&T Kansas, AT&T Missouri, AT&T Oklahoma, AT&T Texas, AT&T California, AT&T Nevada, AT&T Illinois, AT&T Indiana, AT&T Michigan, AT&T Ohio, and/or AT&T Wisconsin based upon service address location. Services may not be available in all areas.


Pricing is based on several criteria, including:

  • Location/rate zones — We have three rate zones in each local access and transport area (LATA). Circuit pricing varies by the location of originating and terminating endpoints.
  • Circuit length — For point-to-point circuits, the fixed monthly recurring charge is based on the length of the circuit and whether the originating and terminating endpoints are located in the same AT&T central office or wire center. Different pricing factors apply to other circuit types.
  • Term discounts — Based on your choice of tariffs and duration, term plans may offer savings on monthly recurring charges and provide price protection.
  • Circuit use jurisdiction — Our rates are regulated by state utility commissions and by the Federal Communications Commission. Specific jurisdiction is determined by your intended use for each specific circuit.
