Basic Rate Interface |
| (BRI) Lower-capacity circuits used with ISDN. They provide up to two separate telephone numbers and need special equipment to connect to regular telephones, fax machines, modems, or key telephone systems. BRI can also connect directly to computer equipment for access speeds up to 128 kbps. |

Bisdn (Broadband Isdn) |
| ITU-T communication standards designed to handle high-bandwidth applications such as video. BISDN currently uses ATM technology over SONET-based transmission circuits to provide data rates from 155 to 622 Mbps and beyond. |
| |
Broadcast |
| 1) Delivery of a transmission to two or more receiving stations at the same time such as over a local network, by radio transmission or by satellite. 2) Protocol mechanism whereby group and universal addressing are supported |

Busy Lamp Field |
| A piece of equipment generally used with a manual key system console, with rows of tiny lights showing which telephone sets are busy and which are idle. |
