Terms Used in This Guide
In this guide, the following terms are used with the meanings shown below:
ADJLK Adjunct link(s). Label for the driver authorization disk or the
switch station type which is required to enable the
appropriate link connection and is provided with the G3PD.
ASAI Adjunct Switch Application Interface. An option on the
DEFINITY ECS switch that enables the ASAI Messaging
Interface between the switch and an Adjunct Processor
(such as a Tserver). This messaging interface allows the
Adjunct Processor to perform call monitoring and control
functions. Also known as CallVisor ASAI.
CVLAN CallVisor Local Area Network (CVLAN) software
implements the ASAI protocol on PCs on a LAN and
provides mapping to an application program interface (API)
for application software.
CSTA Computer Supported Telecommunications Applications. A
CTI standard established by the European Computer
Manufacturers Association (ECMA).
CTI Computer-Telephony Integration
DEFINITY
LAN Gateway
(DLG)
This gateway provides a virtual point-to-point connection
between a particular Telephony Server and an associated
port on the DEFINITY ECS switch. It translates Adjunct
Switch Application Interface ASAI) messages from
Q.931/Q.932 synchronous data frames to TCP/IP Ethernet
packets. DLG is:
n a software package that provides implementation of the
Ethernet-Switch Application Interface (ESAI).
n hardware used to run DLG software. Also known as the
ESAI tunnel protocol.
G3 PBX
Driver (G3PD)
The G3 PBX Driver is a Dynamic Link Library (DLL) on a
Windows NT machine. The G3PD software communicates
with both the DEFINITY G3 PBX and the Tserver to provide
switch services to Telephony Services applications.
Private Data
Support
Library
Private data is a mechanism that allows a switch to provide
value-added services that go beyond those defined in
CSTA. The G3PD provides a number of private data
services (for example, switch-collected call prompter digits
in events, or sending Dual Tone Multi-Frequency (DTMF)
tones that make up the support library).
LAN Local Area Network.
