GDS editable parameters

To program the digital ground start TCP to operate within different countries and networks, modify the TCP-specific parameters stored within the parameter category NCC.X.ADI_GDS. You can modify parameters that program TCP/host interaction, that configure unregulated features or that configure features that can change from switch to switch within the same network.
