Abbreviation/	Explanation
Term
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.
	See also: BRI.
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
