1.3. When To Use This Manual

This PBX Integration Software Reference contains programming information for developing applications in the Windows and Linux operating system environment using the Unified APITM and D/42 runtime library. The Unified API provides a single, basic set of high-level calls used to develop applications across a variety of manufacturer's switches. The D/42 runtime library supports the Unified API and works in conjunction with the standard voice runtime library to enable applications to set up calls and perform PBX call functions using the PBX Integration board.

This guide also includes instructions for using the D/42 demonstration program in the Windows operating system environment.

The sequence for installing software and hardware to develop application programs is as follows:

• Install the PBX Integration hardware in a PC according to the PBX Integration Quick Install Card.
• Install the System Release software for your system following the procedures in the System Release Software Installation Reference to include D/42 and voice support.
• Download the PBX Integration firmware to the boards in your system using the Dialogic Configuration Manager (DCM).

Refer to this manual, the PBX Integration User's Guide, and the Voice Software Reference to develop application programs.
