2.2. The Data Model

2.2.1. Configuration Parameter Values and Device Instantiation

The basic unit of configuration data is the configuration parameter value. There are configuration parameter values for each Intel® Dialogic device in your system configuration. For example, hardware configurable boards, such as the D/41D, require values for the D41DAddress and D41Dinterrupt parameters. (These particular parameters store the valid memory and interrupt information for each Hardware Configurable device in the system.) When the Intel® Dialogic System Service is initiated, it reads the configuration parameter values through the DCM API from the system configuration and uses them to initialize the devices.

For information about the function of each configuration parameter, consult the online help for the DCM GUI client. Access the DCM GUI client by clicking the Configuration Manager-DCM icon from the Intel Dialogic System Software folder. Access the online help by pressing F1 at any window.

Figure 1. DCM API Architecture

A device is a Intel® Dialogic board, such as a D/240SC-2T1. The DCM API enables you to instantiate devices in your system configuration and to query the DCM Catalog to determine which configuration parameter values can be set for a given device.
