HI.
Pardon the cross-posting, I'm not sure where this question really belongs.
I've been trying to wrap my head around how PDTCH/PACCH/PTCCH activation
works. In osmo-bts-sysmo/oml.c there is pdtch_sapis[] which defines what
got to be activated both in DL and UL directions. Right now it's PDTCH
(UL & DL), PTCCH (DL) and PRACH. Note that PACCH (DL) and PTCCH (UL) are
commented out.
Yet I see code dealing with PACCH in osmo-pcu and corresponding log
messages.
So the question is - how does this works? The PACCH seems to be used so
it's somehow activated but apparently not the same way as PDTCH.

Hi.
In sysmobts we use ugly hack to auto-activate BCCH/CCCH on TS0 via
opstart_compl(). How does channel activation looks like for osmo-bts-trx?
On a related note: how do we decide on number of AGCH? In case of
sysmobts it's communicated to L1 in agch.u8NbrOfAgch via lch_par. What
would be equivalent for osmo-bts-trx?
