# Demonstration programs

The following demonstration programs are provided with Natural Access and can be used to verify that the AG 2000C board is operating correctly:

Program | Demonstrates...
--- | ---
ctatest | Natural Access functions.
incta | Handling inbound calls.
outcta | Establishing outbound calls.
prt2prt | Transferring calls from an incoming line to an outgoing line and using the Switching service to make connections and to send patterns.
vceplay | Using the Voice Message service to play messages in voice files.
vcerec | Recording one or more messages to a voice file.

Note: Executables for incta, outcta, and prt2prt are in the respective sub-directories under \nms\ctaccess\demos.

To run these demonstration programs on the AG 2000C board, specify the slot number of the local DSP resource on which to run the program. If Clocking.HBus.ClockMode = STANDALONE, then default switching connections between the on-board DSP resources and signaling modules are initialized as described in Default connections.

To run ctatest on DSP port 0, enter:

ctatest -s0

To run ctatest on DSP port 2, enter:

ctatest -s2

Switching connections must be made between DSP resources and signaling modules using the Natural Access Switching service or the swish utility. Refer to the AG 2000C switching section for more information.

Refer to the Natural Access Developer's Reference Manual for details about Natural Access demonstration programs.
