Well yeah ... that's obvious if you understand what those actually do ..

in burst_ind at each immediate assignement, it will _follow_ it and go
to dedicated mode until the channel is ended. So during all the time
it is in dedicated mode, it won't be listening to CCCH anymore and so
it will miss all the immediate assigmenet that happen during that
time.

Cheers,
