page C-15 for more information.
Configuration
The DPC menus (CLI, Parameter Editor, WSI) provide configuration and cali-
bration control to set up the site maximum power level. Note, however, that the
Parameter Editor and the WSI only support a subset of what is available in the
Command Line Interface (CLI). The DPC menu items are divided into two
parts, the maintenance parameters (DPC Main Menu, table C-1) and the calibra-
tion parameters (Calculate Max Power Menu, table C-2).
Table C-1 and table C-2 show the complete list of the operational parameters
for DPC.
