ATM Services

Asynchronous Transfer Mode (ATM) is the only standards-based technology that has been designed to accommodate the simultaneous transmissions of data, voice, and video.
 
Features and Benefits

Auto Reroute

  • The network will automatically reroute if a failure occurs.

Frame Relay-to-ATM Interworking

  • The ability to select frame or ATM depending on application and bandwidth
  • Migration path as bandwidth demands increase

Quality of Service (QoS)

  • Constant Bit Rate (CBR) — Real-time applications such as video transmissions, multimedia service aggregation, and services that are delay intolerant
  • Variable Bit Rate (VBR) — Ideal for bursty data applications (Internet services)
  • Unspecified Bit Rate (UBR) — Data applications that are delay insensitive

*Service may not originate in the BellSouth nine-state (AL,FL,GA,KY,LA,MS,NC,SC,TN) operating region due to regulatory restrictions.
