Object
column
r/w
hertz Integer32
The highest subcarrier center frequency of the high guard band just above the encompassed spectrum. While this is the center frequency of a subcarrier, it is the high edge frequency of the OFDM channel. Zero means not configured. 24 MHz <= (HighFreqEdge - LowFreqEdge) <= 192 MHz. Must be configured to go in-service.
