Activates or deactivates the F-DPCH.
If the F-DPCH is activated, the dedicated channel is configured as fractional DPCH
and the selected DCH model is ignored (parameter
In that case the DPCH settings displayed in the channel table are related to the F-
DPCH: activation status, power level (plus TPC Offset), channelization code, symbol
rate (fixed), slot format (fixed) and timing offset.
For the channel table see
chapter 6.3.3, "Physical Channel Settings"

Remote command:
TFCI
The checkbox displays the presence of a Transport Format Combination Indicator
(TFCI) in the DPCCH. The status depends on the used DCH Model (parameter
If the TFCI is present, the entered value is transmitted in the TFCI field. If the TFCI is
not present, the TFCI field is filled by DTX bits (discontinuous transmission).
Remote command:
