1.  How to Use This Guide

This guide is for users who use the Global Call application programming interface (API) and related software to develop Linux or Windows applications in an analog loop start interface environment.

Complete reference information and programming guidelines for the Global Call API are given in the companion documents, Global Call API Library Reference and Global Call API Programming Guide. Certain Global Call functions have additional functionality or perform differently when used in an analog loop start environment. The general function descriptions in the Global Call API Library Reference do not contain detailed information on a particular technology. Detailed information in terms of the additional functionality or the difference in performance of those functions in an analog loop start environment is contained in this Global Call Analog Technology User's Guide.

Throughout this document, the terms analog environment, analog loop start, and analog interface refer to the telephone line interface that receives analog voice and telephony signaling information from the telephone network.

NOTE:

Differences between the implementation of a Global Call application in a Linux or a Windows environment are either described parenthetically or are presented in separate paragraphs or sections. Information that is specific to the use of DM3 or Springware boards is identified explicitly. Information that is specific to the use of the PDKRT or ANAPI call control library is identified explicitly.

The rest of this chapter describes the organization of this guide, the products covered by this guide, and related publications.
