MM_C_RTS_CLEAR_COMMENT
3.7.3 MM_C_SHIFT_CR
Purpose
Perform a shift function on the CR list, i.e. promote a delegate from the CR list to the CS list.
The shift differs from other Comment Request list or Speakers list functions in such a way
that the promoted delegate is always added to the comment speakers list, whether this list is
full or not. Besides, of all units present in the SPK list the microphones will be turned off. This
includes the following steps:
1. Remove the indicated Comment Request entry from the CR list. When the indicated entry
does not exist in the CR list an error is returned.
2. Turn off the microphones off all entries in the SPK list.
3. Look if there is an entry free in the CS list. If not, then removing the first unit in the CS list
will create a free entry.
4. Create from the Comment Request entry a SPK entry and add this to the CS list.
If however, the delegate was already present in the normal speakers list, then the Comment
Request entry is removed from the CR list and the microphone of the entry in the SPK list is
switched on again.
Note: Currently the operation mode MM_C_OPERATOR_WITH_COMMENT_LIST is only
allowed with a maximum number of active speakers of 1. Also the CS list has currently a
maximum length of 1. This means that when a comment request is shifted, the microphone of
the current speaker in the SPK list is switched off and the current speaker in the CS list, if
present, is removed to make place for the shifted CR entry.

3.8 MM Speechtime functions
This section describes the functions to manipulate the speech-time.
There is no synchronization between different controllers, e.g. Remote Control and Control-
PC. The last controller, which is used, is the active one.
It is the responsibility of the controller to invoke the different functions when necessary. The
CCU won’t do this for you. The controller should check the speech-time for each individual
speaker and invoke the relevant speech-time function.
3.8.1 MM_C_SET_SPEECHTIME_SETTINGS
Purpose
This function stores the speech-time settings in the CCU.
