Explanation

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

D-channel serves all BRI channels, while the remaining

D-channels are used for data transfer.
