This is the default TX power level of the traffic modem for the Video call, in
dBm (Range: -30 to -5 dBm). This power applies to the selected grade of
service. If a videoconference is initiated at a different data rate, the power is
scaled accordingly.
Note: The power level setting must be based upon the link budget with a 10
kbps, QPSK, R=1/2 carrier.
The MIDAS System will give a recommended power level for any video call
based upon the data rate, modulation, and FEC of that call. The operator
can use the recommended power level or select the appropriate power level.
