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

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.

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

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.
