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.

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
