Table 10 - Spectrum Management Change State Key - Motorola PTP 600 Series User Manual

The X-axis shows a stylized view of the 9 or 10 selectable 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 (channel 5 in Figure 63) is always marked using hatched green and white
lines. The width of the hatching is directly proportional the 30 MHz spectral occupancy of the
channel.
The individual channel metrics are displayed using a colored bar and an 'I' bar.
The colored bar represents the following channel state:
Green Active
Orange Interference
Blue Available
Grey Barred

The channel is currently in use, hosting the Point-to-Point
wireless link
The channel has interference above the interference threshold
The channel has an interference level below the interference
threshold and is considered by the Spectrum Management
algorithm suitable for hosting the Point-to-Point link
The system administrator has barred this channel from use.
For improved visibility, an additional red 'lock' symbol is used
to indicate that a channel is barred.
