1. How To Use This Manual

1.1. Audience

This manual is written for programmers and engineers who and are interested in using the D/42 series software (the Dialogic standard for PBX Integration series boards), together with standard D/4x voice software, to develop voice and call processing applications on PBX Integration boards for a PBX system.

When this manual addresses "you," it means "you, the programmer," and when this manual refers to the "user," it means the end-user of your application program.

If you are experienced with voice technology and Dialogic products, you may prefer to deal strictly with information found in Sections 3 and 4 in this manual. These sections contain comprehensive and detailed technical information for programming an application with C language library functions and data structures.

If you are new to Dialogic products and voice technology, you may prefer to start with the Features Guide. The Features Guide, contained in the Voice Software Reference, provides an introduction to the voice products, with explanations and help beyond a strictly technical level so that you can quickly learn the voice software. This includes descriptions of how to use the voice processing, signaling, and Call Progress Analysis features and how to design a multi-line voice application.

NOTE:

PBX Integration boards only support CPA when used in the default routing configuration. For instance, if a voice resource of a D/82JCT-U is listening to a front end other than the default (its own), it may return a disconnected result. This is because these boards support the call progress analysis feature of dx_dial( ), only when a board is using the default TDM routing. In other words, PBX Integration board voice resources cannot be used to provide CPA capability for other boards.
