AT&T 7200 series Audix Standalone, Automatic Alternate, Routing AAR, Automatic Call, Channel

GLOSSARY GL-3

_______________________________________________________________________________________
_
AUDIX Standalone	An AUDIX system that has no data link and allows AUDIX service to be
	provided in association with any communications system but with less
	functionality than when AUDIX is integrated via a data link with a
	communications system. See also AUDIX.
Automatic Alternate	A feature that provides optimum routing for private-network calls by
Routing (AAR)	selecting, in descending order of desirability, the best route available.
Automatic Call	A feature that directs calls to agents who have been administered in groups
Distribution (ACD)	called splits. ACD uses the most-idle agent, direct, and circular (for
	System 85 and DEFINITY® Communications System Generic 2 only)
	distribution methods. See also Enhanced Uniform Call Distribution,
	and Uniform Call Distribution.
automatic calling unit	An automatic dialing device that enables a machine to place calls over a
(ACU)	communications system. Also called autodialer.
Automatic Route	A feature that provides optimum routing for public-network calls by
Selection (ARS)	selecting, in descending order of desirability, the best route available. See
	also high-volume tandem.
AVD	See alternate voice/data.
B-channel	For an Integrated Services Digital Network (ISDN), a 64-kbps channel
	accompanied by timing that is intended to carry a wide variety of digital
	information streams, such as voice at 64 kbps, data at up to 64 kbps,
	wideband voice encoded at 64 kbps, and voice at less than 64 kbps, alone
	or combined with other digital information streams. Also called bearer
	channel. See also D-channeland B-channelcut-through.
B-channel cut-through	The side, either user or network, of the Integrated Services Digital
	Network basic rate interface (ISDN-BRI) that the specified B-channel uses
	to transfer voice or data information. See also B-channel.
bandwidth	The difference, expressed in hertz, between the highest and lowest
	frequencies in a range of frequencies that determine channel capacity.
basic rate interface (BRI)	A standard Integrated Services Digital Network (ISDN) frame format that
	specifies the protocol used between a communications system and a
	terminal. BRI runs at 192 kbps and provides two 64-kbps voice or data
	B-channels and one 16-kbps signaling and data D-channel per port. The
	remaining 48 kbps are used for framing and D-channel contention.
baud	In telecommunications applications, a unit of transmission speed equal to
	the number of signal events per second. See also bit rate and bits per
	second.
