Yes. And it also has SACCH slots that the CBCH doesn't have.

Yup.
It seems that CBCH never have subslots ? (Looking at GSM 05.02 Clause
7 Table 3 of 9).
If it says SDCCH4 it's always B32..B35 (like a SDCCH4 subslot 2)
If it says SDCCH8 it's always B8..B11 (like a SDCCH8 subslot 2)
I'll look into adding a command to support going to that channel along
with the appropriate scheduling.

No, we can only get data from 1 timeslot in each frame, so if it's in
a SDCCH8 there can be conflicts.
(If it's in SDCCH/4 then that should be OK)
We'll probably be able to do that only when we get to DRX (where we
only listen to specific slots).
Cheers,
Sylvain
