AGC | Auto Gain Control. A mechanism that regulates noise and | |
| audio volume by keeping the received signal of all | |
| participants balanced. | |
|

Bandwidth | Defines the information carrying capacity of a channel. In | |
| analog systems, it is the difference between the highest | |
| frequency that a channel can carry and the lowest, | |
| measured in hertz. In digital systems, bandwidth is | |
| measured in bits per second. The larger a connection's | |
| bandwidth, the more data can be transmitted in a given | |
| amount of time, allowing for greater video resolution and | |
| more sites in a conference. For more information, see | |
| Line Rate. | |

Bonding | Bandwidth ON Demand INterpolarity Group. A | |
| transmission protocol that aggregates two 64 Kbps B | |
| channels to function as one 128 Kbps channel. When | |
| using several BRI channels, Bonding means that only one | |

Bps, Kbps | Bits and kilobits per second; a unit of bandwidth, which is | |
| the amount of data that can flow during one second over a | |
| communications line (using a transmission medium). | |
| 1 Kbps = 1000 Bps | |
