GL-5  
appearance
A software process that is associated with an extension and whose purpose is to supervise a call. 
An extension can have multiple appearances. Also called call appearance, line appearance, and 
occurrence. See also 
c all ap p earanc e.
application
An adjunct that requests and receives ASAI services or capabilities. One or more applications can 
reside on a single adjunct. However, the switch cannot distinguish among several applications 
residing on the same adjunct and treats the adjunct, and all resident applications, as a single 
application. The terms application and adjunct are used interchangeably throughout this document.
applications processor
A micro-computer based, program controlled computer providing application services for the 
DEFINITY switch. The processor is used with several user-controlled applications such as traffic 
analysis and electronic documentation.
application service element
See 
capability group.
architecture
The organizational structure of a system, including hardware and software.
ARS
See 
Automatic  Route Selec tion (ARS).
ASAI
See 
Ad junc t-Switc h App lic ation Interfac e (ASAI)
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).
association
A communication channel between adjunct and switch for messaging purposes. An active 
association is one that applies to an existing call on the switch or to an extension on the call.
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 
transmission is advantageous when transmission is not regular (characters typed at a keyboard). 
Also called asynchronous transmission. See also 
synchronous d ata transmission.
asynchronous data unit (ADU)
A device that allows direct connection between RS-232C equipment and a digital switch.
asynchronous Transfer Mode (ATM)
A packet-like switching technology in which data is transmitted in fixed-size (53-byte) cells. ATM 
provides high-speed access for data communication in LAN, campus, and WAN environments.
AT B
See 
All trunks b usy (ATB). 
AT D
See 
Attention d ial (ATD).
attendant
A person at a console who provides personalized service for incoming callers and voice-services 
users by performing switching and signaling operations. See also 
attend ant c onsole.

Glossary and Abbreviations 
GL-6  
AT M
See 
async hronous Transfer Mod e (ATM).
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 
attend ant.
Attention dial (ATD)
A command in the Hayes modem command set for asynchronous modems.
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.
AUDIX
See 
Aud io Information Exc hange (AUDIX).
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 they arrive.
Auto-In Work mode
One of four agent 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 one becomes available.
Automatic Call Distribution (ACD) split
A method of routing calls of a similar type among agents in a call center. 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.
Automatic Circuit Assurance (ACA)
A feature that tracks calls of unusual duration to facilitate troubleshooting. A high number of very 
short calls or a low number of very long calls may signify a faulty trunk.
Automatic Number Identification (ANI)
Representation of the calling number, for display or for further use to access information about the 
caller. Available with Signaling System 7.

GL-7  
automatic restoration
A service that restores disrupted connections between access endpoints (nonsignaling trunks) and 
data endpoints (devices that connect the switch to data terminal and/or communications 
equipment). Restoration is done within seconds of a service disruption so that critical data 
applications can remain operational.
Automatic Route Selection (ARS)
A feature that allows the system to automatically choose the least-cost way to send a toll call.
automatic trunk
A trunk that does not require addressing information because the destination is predetermined. A 
request for service on the trunk, called a seizure, is sufficient to route the call. The normal 
destination of an automatic trunk is the communications-system attendant group. Also called 
automatic incoming trunk and automatic tie trunk.
AUX
Auxiliar y
auxiliary equipment
Equipment used for optional system features, such as Loudspeaker Paging and Music-on-Hold.
auxiliary trunk
A trunk used to connect auxiliary equipment, such as radio-paging equipment, to a communications 
system.

when involved in non-ACD activities such as taking a break, going to lunch, or placing an outgoing 
call.

CCS or hundred call seconds
A unit of call traffic. Call traffic for a facility is scanned every 100 seconds. If the facility is busy, it is 
assumed to have been busy for the entire scan interval. There are 3600 seconds per hour. The 
Roman numeral for 100 is the capital letter C. The abbreviation for call seconds is CS. Therefore, 
100 call seconds is abbreviated CCS. If a facility is busy for an entire hour, then it is said to have 
been busy for 36 CCS. See also 
Erlang.
capability
A request or indication of an operation. For example, 
Third Party Make Call is a request for setting 
up a call; 
event report is an indication that an event has occurred.
capability group
Set of capabilities, determined by switch administration, that can be requested by an application. 
Capability groups denote association types. For example, 
Call Control is a type of association that 
allows certain functions (the ones in the capability group) to be performed over this type of 
association. Also referred to as administration groups or application service elements (ASEs). 
CA-TSC
Call-Associated Temporary Signaling Connection
cause value
A value is returned in response to requests or in event reports when a denial or unexpected 
condition occurs. ASAI cause values fall into two coding standards: Coding Standard 0 includes any 
cause values that are part of AT&T and CCITT ISDN specifications; Coding standard 3 includes any 
other ASAI cause values. This document uses a notation for cause value where the coding 
standard for the cause is given first, then a slash, then the cause value. Example: CS0/100 is 
coding standard 0, cause value 100.
