if the Coordinator is constrained to one channel, and
the specified Pan Id has already been established on that channel, the newly starting Coordinator will make
successive changes until it achieves a unique Pan Id. A Router or End-Device newly joining will have no way of
knowing the value of the “de-conflicted” Pan Id established, and will therefore join only the Pan Id specified. A
similarly challenging scenario arises when the permitted channel mask allows more than one channel and the
Coordinator cannot use the first channel because of a Pan Id conflict – a Router or End-Device will join the
specified Pan Id on the first channel scanned, if allowed.
