Only for DVB-S2 mode except for Air(XPE) processing modes.
Description
Configuration of the FEC-rate and modulation. The selection of the FEC-
rate and modulation are coupled and depend on the present modulation
standard and capability of the device.
Because the selection of a new FEC-rate and/or modulation type changes
the symbol rate and thus the bandwidth of the signal, transmit is disabled.
After verification of the occupied bandwidth, the operator has to re-enable
transmit to go back on air.
In DVB-S2 mode which supports dynamic changes of FEC-rate and/or
modulation, transmit is only disabled when the symbol rate changes i.e.
when the rate priority command is set to "interface rate".
Remark: The selection of a FEC-rate and/or modulation type for which the
present symbol rate is outside the allowed limits, will be indicated by an
incompatibility alarm. Only those selections possible with the current
device capability will be listed.
