.
ASCII (American Standard Code for Information Interchange)
The standard code for representing characters in digital form. Each character is represented by an
8-bit code (including parity bit).
asynchronous data transmission
A method of transmitting data in which each character is preceded by a start bit and followed by a
stop bit, thus permitting data characters to be transmitted at irregular intervals. This type of
transmission is advantageous when transmission is not regular (characters typed at a keyboard).
Also called asynchronous transmission. See also synchronous data transmission
.
asynchronous data unit (ADU)
A device that allows direct connection between RS-232C equipment and a digital switch.
attendant
A person who uses a console to provide personalized service for incoming callers and
voice-services users by performing switching and signaling operations. See also attendant console
.
attendant console
The workstation used by an attendant. The attendant console allows the attendant to originate a
call, answer an incoming call, transfer a call to another extension or trunk, put a call on hold, and
remove a call from hold. Attendants using the console can also manage and monitor some system
operations. Also called console. See also attendant
.
Audio Information Exchange (AUDIX)
A fully integrated voice-mail system. Can be used with a variety of communications systems to
provide call-history data, such as subscriber identification and reason for redirection.
auto-in trunk group
Trunk group for which the CO processes all of the digits for an incoming call. When a CO seizes a
trunk from an auto-in trunk group, the switch automatically connects the trunk to the destination —
typically an ACD split where, if no agents are available, the call goes into a queue in which callers
are answered in the order in which their calls arrive.
Auto-In Work mode
One of four work modes: the mode in which an agent is ready to process another call as soon as
the current call is completed.
Automatic Alternate Routing (AAR)
A feature that routes calls to other than the first-choice route when facilities are unavailable.
Automatic Callback (ACB)
A feature that enables internal callers, upon reaching a busy extension, to have the system
automatically connect and ring both parties when the called party becomes available.
Automatic Call Distribution (ACD)
A feature that answers calls, and then, depending on administered instructions, delivers messages
appropriate for the caller and routes the call to an agent when an agent becomes available.
Automatic Call Distribution (ACD) Split
A method of routing calls of a similar type among agents in a split. Also, a group of extensions that
are staffed by agents trained to handle a certain type of incoming call.
Automatic Calling Unit (ACU)
A device that places a telephone call.
