Explanation
Auto Gain Control. A mechanism that regulates noise and
audio volume by keeping the received signal of all
participants balanced.
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.
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.
See also: BRI.
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
