Prime Advantage

Prime Advantage is a high-capacity switched digital access service that provides 23 digital information channels and a separate channel for signaling — all on a single pipe. Setting a new standard for business communications technology, Prime Advantage improves network management and efficiency while making bulk data transport affordable.


  • 23 information channels: Carry voice, video, or data information at speeds up to 64 Kbps
  • Caller ID: Displays the number of the calling party, providing valuable information for customer service and telemarketing operations
  • Clear channel mode: 23 information channels free to operate in a clear channel mode — end-to-end digital connectivity for Prime Advantage users communicating with other clear channel end points
  • Call-by-call service selection: Achieve optimum efficiency by allowing you to manage the allocation of voice, video, and data channels
  • Alternate routing arrangements: Bypass a long distance carrier that may be suffering an outage


  • Reduced costs: By consolidating PBX and networking services, efficiencies can be achieved and expenses reduced
  • Flexibility: Voice, video, and data can be transported over a single pipe that also provides access to network services available from other carriers
  • Security: Automatic alternate routing to your secondary long distance carrier provides diversity in case of failure by the primary carrier
  • Reduced hardware requirements: By consolidating 23 channels into a single DS1 circuit card in your PBS or other communications server, you can reduce your hardware needs
