A Typical Avaya Computer Telephony Configuration
This section provides a high-level description of the hardware and software components
used in a typical Avaya Computer Telephony configuration.
Hardware Components in a Typical Implementation of Avaya
Computer Telephony
The basic hardware components in a typical Avaya Computer Telephony configuration are
as follows.
● DEFINITY Switch configured with ASAI
The DEFINITY switch is a device that processes calls (incoming, outgoing, and
internal) and connects them to the proper destinations.
In the context of Avaya Computer Telephony, the role of the DEFINITY switch
changes. In a Avaya Computer Telephony implementation, the DEFINITY switch
“hands off” call monitoring and call control functions to the Avaya Computer Telephony
server (or the adjunct processor). The means of effecting this handoff is the Adjunct
Switch Application Interface — ASAI.
To support Avaya Computer Telephony, the DEFINITY switch must be configured with
Adjunct Links or an ASAI Interface. DEFINITY switches that support CTI are as
follows.
- DEFINITY CSI, Si, and R (running software release G3V4 or later), Avaya
MultiVantage on a DEFINITY Server CSI, SI, and R, and Avaya MultiVantage S8700
configurations
Note:
Note: G3V4 requires a field maintenance release.
- DEFINITY ONE/IP600 Release 2 (R2), or later, and Avaya MultiVantage S8100
configurations
● DEFINITY LAN Gateway
The DEFINITY LAN Gateway, or DLG, is software that acts as a transport mechanism
that allows the DEFINITY switch to communicate with the Avaya Computer Telephony
server. It is required for all Avaya Computer Telephony implementations.
- DEFINITY CSI, Si, and R (running software release G3V4 or later), Avaya
MultiVantage on a DEFINITY Server CSI, SI, and R, and Avaya MultiVantage S8700
configurations use a Multi-Application Platform for DEFINTY (MAPD) based DLG.
