To enable TelAF Data Call Service, run the following command to compile the TelAF
            simulation image under the TelAF root directory.

    # In Dev PC HOST
    make simulac TELAF_SIMULATION_ENABLE_DCS=yCopy to clipboard

    # In Dev Container
    cat >> simulation/.simulation.build << EOF
    export TELAF_SIMULATION_ENABLE_DCS = y
    EOF
    
    echo "make simula-c" > simulation/workstation/.simula.dev.action.sh
    make simula-xCopy to clipboard

For multi-profile data connection, see the YAML file under
                telaf-simulation/sml/config/devices/default.yaml.
