The TCH/FS 4.8K and 9.6K are coded channels that are available with Option QFP.To open the Data node, click Data in the tree view. Use the Data window to define the bits in the bursts. The cells displayed in the Data section are determined by the Channel Type for the selected timeslot as defined in the Timeslot window.

from one timeslot to another.
Use the Data window to define the bits in the bursts. The cells displayed in the Data section are determined by the burst type (Timeslot Type) for the selected timeslot as defined in the Timeslots window. In the window shown above, Timeslots 0 is set up for a data cell with a Traffic Channel Full rate (TCH/F n.nK) Bursts.
Tail bits are set by the software. This cell is not editable.

Select an encoded
, or . The selected data is coded continuously across the RLC data block per the 3GPP standards. An independent version of the selected data is coded across the MAC header.To perform a receiver test with a continuous PN sequence, select .
You can enter 1 (control channel burst) or 0 (data channel burst). The default is 0.

If you manually change a timeslot (channel type), the training sequence for that timeslot resets to
provided that the training sequence was not previously changed for the new channel type.
