With default settings in SFH, all timeslots in the frame are using the same frequency.
There is one exception though, in BBH : the timeslot 0 of each TRX uses different frequency than timeslots 1 to 7.
… but only for BBH.
For SFH, it could be possible to define different hopping sequences for each timeslot, but that’s:
1/ terribly difficult to configure
2/ absolutely useless (who said dumb?)
