Cell Off operating mode and Active Cell operating mode share the same settings. However, Cell Off mode allows you to change the parameters that cannot be changed during Active Cell operation but used for call processing, such as downlink and uplink channel number (UARFCN), reference measurement channel configuration (Channel Type), signalling radio bearer configuration, etc.
Use Cell Off operating mode to set up those downlink and uplink parameters before establishing a connection to the UE (mobile station). After making the settings, switch to Active Cell operating mode to begin generating the downlink signal. Use CALL:OPERating to select operating modes.
