5.3.2 RTTT Avoidance and Other Channel Use Restrictions
Whe
re regulatory restrictions apply to certain channels these channels are barred. RTTT
avoidance may be necessary in all channel bandwidths. The number of channels barred is
dependant on the channel raster selected. For example see the effect of the UK RTTT
channel restrictions in the 30 MHz bandwidth (Figure 13), where blocks in red indicate
cha
nnels that are barred. Barred channels are indicated by a “No Entry” symbol displayed on
the “Spectrum Management” web page, see Section 8.3.9 “Spectrum Management Control -
With Ope
rational Restrictions”.
