NOTE
l The enhancement modes QPSKSTRONG, 16QAMSTRONG, 512QAM, 512QAMLIGHT,
1024QAM, and 1024QAMLIGHT can be implemented only when the IS3 mode of the intermediate
frequency (IF) board is used in the 6 GHz, 7 GHz, 8 GHz, 11 GHz, 13 GHz, 15 GHz, 18 GHz, 23 GHz,
26 GHz, 28 GHz, 32 GHz, 38 GHz and 42 GHz working frequencies.
l The enhancement modes QPSKSTRONG, 16QAMSTRONG, 512QAM, 512QAMLIGHT,
1024QAM, and 1024QAMLIGHT for the 10 GHz frequency band must work in IS3 mode of the
intermediate frequency (IF) board provided in RTN900 V100R005C01 or later.
