Introduction
Organization of This Document
This document is organized as follows:
Chapter 1, "Introduction" provides a list of chapters in this document, an overview of the DEFINITY G3 PBX Driver, terminology important to the understanding of
Chapter 2, "Security and Configuration" describes security measures and how to reconfigure the G3PD using the G3 PBX Driver Configuration utility. Instructions are also provided on how to use the PBX Link Change utility to change the IP address or hostname of an active link.
Chapter 3, "Maintenance" describes the tools that can be used to observe and test the G3PD. An Operations, Administration, and Maintenance (OA&M) utility, the DEFINITY G3PD Administrator utility, can be used from a Microsoft Windows 2000, Windows NT (4.0 or later), Windows XP, or Windows 95 machine to perform OA&M tasks.
Chapter 4, "Troubleshooting" describes problems that can occur with the DEFINITY G3 PBX Driver (G3PD), the switches, and the switch links, and suggests possible solutions to these problems.
Overview of DEFINITY G3 PBX Driver
The DEFINITY G3 PBX Driver (G3PD) allows Telephony Services applications to communicate with a DEFINITY G3 PBX.
nTelephony Services applications access the G3PD through Telephony Services (the security database and advertised services).
nCVLAN applications bypass Telephony Services and access an ASAI link directly using CallVisor Adjunct Switch Application Interface (ASAI) messages.
The primary function of the G3PD is to interpret Computer Supported Telecommunications Application (CSTA) requests made by Telephony Services applications and to forward them to the PBX. To do this, the G3PD converts the CSTA requests into CallVisor ASAI messages, and uses the CVLAN API to send and receive these messages across an ASAI link connecting your Tserver to the DEFINITY ECS system. Customer applications on the Tserver can use this API directly. In addition, clients can access the API with CVLAN. See Figure
