DTX is employed to control downlink dedciated channel’s bit rate.

uplink transmission is continuos and changes in bit rate can be achieved by modifying the spreading factor of the code sequence being used.

Downlink:

Spreading factor is chosen to support the highest bit rate of TFCS.

The variable bit rate is implemented with discontinuous transmission (DTX), swithcing off the transmission during the DPDCH fields in certain time slots.
