Hopping Counter
This is used to record the number of channel hops. The number in the “(+)” brackets
indicates the number of channel changes since the last screen refresh.
Interference Threshold
Spectrum Management uses the interference threshold to perform instantaneous
channel hops. If the measured interference on a channel exceeds the specified
threshold, then i-DFS will instruct the wireless to immediately move to a better
channel. If a better channel cannot be found the PTP 600 Series will continue to use
the current active channel. (Default –85 dBm).
Channel Bandwidth (not configurable)
This shows the value of the variable channel bandwidth selected.
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.
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.
