I'm not sure if your response covers the question I raised.
I see, I mistook the 'gprs mode' for the internal TS flag whether GPRS is
currently active on a TCH_F_PDCH, but you mean the VTY config item.
What if you have a openbsc.cfg with a bts that has
'gprs mode none' but
still has a timeslot in GSM_PCHAN_TCH_F_PDCH mode? The intended
operation in that case is that it will be treated as a pure TCH/F, and
no attempts to switch to PDCH are made.
Indeed, we would switch to PDCH anyway. Aside from it being meaningless
to have GSM_PCHAN_TCH_F_PDCH time slots with 'gprs mode none', I agree
that we shouldn't send PDCH ACT in that case.
It's easy to work around: just configure TS as GSM_PCHAN_TCH_F. So I'm not
putting this high up on the todo list.
