What exactly is Basic Rate Interface (a.k.a. BRI)?

BRI is a type of ISDN connection, found most likely in residential services. BRI allows a single telephone line to carry voice, video, and data simultaneously to give you a better and more efficient and affordable service.

BRI connections are characterized as:

• ISDN channel totalling a data rate of 144kbps: two 64 kbps (B) channels and one 16 kbps (D) channel
• B channels are used for voice or user data, while D channels are used for control and signalling and/or X.25 packet networking.
  

With a BRI service has the following features:

• Carry voice, video and data simultaneously
• All-digital service
• Flexible capacity on demand by using existing wiring

A BRI service has the following benefits:

• Enables efficiency by simultaneously transmitting voice, video, and data
• Improves customer service for your company by allowing multiple calls to be received over one line
• Increases transmission accuracy and speed by operating over a digital network. Digital network reduces errors in data transmission and allows data to be sent at higher speeds compared to analog modems.
• Improves network connectivity by allowing multiple locations to share information without the need for a dedicated line
• Increases the speed and flexibility of communications from remote or home office locations.
• BRI Saves money by operating over the twisted-pair wiring. This means that no special cabling is necessary.
