About This Manual

This manual describes the Natural MicroSystems Digital Trunk Monitor (DTM) service API. This API allows CT Access applications to monitor for alarms on digital trunks, and to gather performance statistics.
This document is targeted to developers of telephony and voice applications who are using CT Access. This document defines telephony terms where applicable, but assumes that the reader is familiar with telephony concepts. It also assumes that the user is familiar with C programming.
This manual is organized as follows: For... See... An overview of the DTM service Chapter 1 - Introduction Information on setting up and using DTM in a CT Access application Chapter 2 - Using the DTM Service A list of data structures referenced in DTM function calls Chapter 3 - Alphabetical Function Reference A reference of DTM API functions Chapter 4 - Data Structures A description of the DTM demonstration program included with CT Access Chapter 5 - Demonstration Program A list of terms and definitions Appendix A - Glossary A list of events and CT Access errors that can be returned by DTM functions Appendix B - Event and Error Summary
