Adjunct Switch Application Interface
(ASAI)
Adjunct Switch Application Interface (ASAI) allows adjunct applications to
access a collection of Communication Manager features and services. Integration
with adjuncts occurs through APIs. ASAI is part of Avaya computer telephony.
ASAI links Communication Manager and adjunct applications. The interface
allows adjunct applications to access Communication Manager features and
supply routing information to the system.
ASAI improves ACD agents’ call handling efficiency by allowing an adjunct to
monitor, initiate, control, and terminate calls on the switch. ASAI may be used for
Inbound Call Management (ICM), Outbound Call Management (OCM), and
office automation/messaging applications.
ASAI uses two transport types:
■ ISDN-BRI transport (ASAI-BRI)
■ LAN gateway transmission control protocol/internet protocol transport
(LAN gateway TCP/IP).
ASAI messages and procedures are based on the ITU-T Q.932 international
standard for supplementary services.
Co-resident DEFINITY LAN Gateway
In simplest terms, the DEFINITY Local Area Network (LAN) Gateway, or DLG,
is an application that enables communications between TCP/IP clients and
Communication Manager call processing. In more technical terms, the DLG
application is software that both routes internetwork messages from one protocol
to another (ISDN to TCP/IP) and bridges all ASAI message traffic by way of a
TCP/IP tunnel protocol.
In previous configurations, a DEFINITY LAN gateway (DLG) was connected
externally on a separate TN801 MAPD circuit pack. The DLG application is
packaged internally where it co-resides with the Communication Manager. The
internally packaged DLG is referred to as the co-resident DLG.
Co-resident DLG is only available with the S8300 Media Server.
Co-resident DLG provides the functionality of the Adjunct/Switch Application
Interface (ASAI) using an ethernet transport instead of a Basic Rate Interface
(BRI) transport. In the S8300 Media Server, connectivity is provided through the
processor’s ethernet.
