Change subject: ASCI: Add a flag to turn transmitter off or on
......................................................................
ASCI: Add a flag to turn transmitter off or on
This flag can be used to turn transmitter off for "group receive mode"
or for handover procedure. The flag is stored in the channel description
of the mobile application. It is sent to layer 1 when switching to
dedicated channel or when changing TCH mode.
At the layer 1 the transmitter is turned off while the receiver is still
active. This is done by:
* scheduling a TX dummy task for TCH bursts
* scheduling no TX task for SACCH bursts
* not enabling the transmit window
Related: OS#5364
