ASAI Overview 

Overview of the Adjunct/Switch
Application Interface Feature

The AT&T Adjunct/Switch Application Interface (ASAI) is an optional package that 
may be installed on top of the standard CONVERSANT Voice Information System 
software.  Instructions for installing the Adjunct/Switch Application Interface are 
provided in Chapter 3, "ASAI Installation". 

The AT&T Adjunct/Switch Application Interface provides an Integrated Services 
Digital Network (ISDN)-based interface between AT&T PBX’s and adjunct proces-
sors.The VIS ASAI feature supports this application interface for communications 
with the AT&T DEFINITY Communications System, Generic 3i (hereafter referred 
to as DEFINITY Generic 3i).This digital signaling interface allows the VIS to moni-
tor and route calls on the DEFINITY Generic 3i switch.  When used in conjunction 
with standard Tip/Ring (T/R) or Line Side T1 (LST1) interfaces, the ASAI interface 
allows the VIS to monitor and control calls delivered to a T/R or LST1 channel on 
the VIS.

Access to ASAI capabilities is provided through the Script Builder application gen-
eration language.  Access to ASAI capabilities at the Script Builder level mini-
mizes the effort required to implement ASAI-based applications.  For example, 
there is no need to receive, parse, and process individual, lower-level ASAI mes-
sages.  Additional Script Builder actions give the script designer high-level access 
to ASAI capabilities.  These ASAI capabilities can be used to design the following 
types of applications. 

 These types of applications are discussed later in this chapter.
