6-15-3 CHANNEL NUMBERING
It is important the first control channel number used here is a channel defined in the
Normal Hunt table of the Radio Unit. Although an RU is instructed to MOVE to another
control channel, a channel is not acquired unless the channel is in the Normal Hunt
table. Otherwise, the RU enters a Comprehensive Hunt. This may take many minutes
before acquiring a channel and going into service.
Radio Units operating in the UK Band III sub-bands 1 and 2 use a slightly different
channel designation.
