4.1 Starting the Demo

Start the Global Call API demo program by typing the program name at the command line. The program name is:
gc_basic_call_model

Notes:

1. A protocol package must be installed on the system prior to running the Global Call API demo program. The configuration file must specify an installed protocol. Refer to the documentation accompanying the separately orderable Global Call Protocols Package for information on installing protocols.
2. Before running the demonstration program with a T-1 robbed bit protocol and the ICAPI call control library, disable the DTI Wait Call firmware function by changing the default selection in the icapi.cfg file. See the $14 parameter description in the "ICAPI Configuration File" chapter of the Global Call E-1/T-1 Technology User's Guide for details.
3. When using PDK protocols, disconnecting and reconnecting the cable causes the demo to exit.

The Global Call API demo program displays the status of the program as it runs. The following is an example of the output generated on a Linux system:
