AT&T^® Basic Rate ISDN (BRI) service allows a single telephone line to carry voice, video, and data simultaneously to give you more efficient and affordable service.

BRI has:

• Two B channels to carry voice, video, or data
  • Each B channel contains speeds as high as 64 Kbps
  • B channels can be combined to offer up to 128 Kbps for applications that require more bandwidth
• A third channel (the D channel) to carry the call set-up information and low-speed packet data

• One line with multiple directory numbers
• Extended networks with high speed connections and large bandwidth for remote locations
• Connect across a campus or across the country

• All-digital service
• Speeds up to 128 Kbps
• Integrated voice, video and data
• Flexible capacity on demand
• Uses existing wiring

• Enables efficiency. Voice, video, and data are transmitted simultaneously
• Improves customer service. Multiple calls can be received over one line
• Increases transmission accuracy and speed. Since BRI service operates over a digital network, errors in data transmission are reduced. Data is sent at higher speeds than with analog modems
• Improves network connectivity. Multiple locations can share information without the need for a dedicated line
• Increases the speed and flexibility of communications from remote or home office locations.
• Saves money. No specialized cabling is required. BRI operates over the twisted-pair wiring used for telephone service.
