7.9.6 Barring Channels
Channels can only be barred / unbarred by the system administrator from the master
Spectrum Management web page. The barring / unbarring operations are disabled on the
slave web page. If an attempt to bar / unbar a channel is made at the slave, a warning dialog
is generated.
Barring/Unbarring of channels is performed by clicking the appropriate channel on the local or
peer channel spectrum plots on the master web page. Each bar / unbar attempt will be
proceeded by a confirmation dialog. It should be noted that the channel bar will take effect
immediately and is not related to the measurement quantization period.
7.9.7 Master and Slave Channel Spectrum Graphics
Spectrum Management presents its computed statistical measurements in a graphical display
on both the master and slave Spectrum Management web page. See Figure 71 for an
example.
The X-axis
shows a stylized view of the wireless channels. It is important to note that
adjacent channels on the display have a 10 MHz overlap. The display separates the display
of channels to help the clarity of the resultant display. The axis is labeled using the channel
center frequencies in MHz.
The Y-axis shows the interference power levels from –100 to –40 dBm.
The active channel is always marked using hatched green and white lines. The width of the
hatching is directly proportional the channel bandwidth spectral occupancy of the channel.
The individual channel metrics are displayed using a colored bar and an ‘I’ bar.
