Paging group is needed when sending Immediate Assignment over PCH. […]

I am a bit puzzled as well here but I think I remember now. There was the problem with the DL TBF and sending the Immediate Assignment via PCH solved it. So the Immediate assignment here goes through the PCH and not through the AGCH. I have corrected this here for now.

The SAPI PCU_IF_SAPI_AGCH_DT is not used in osmo-pcu.git, thats correct. The patch is still in review, see: I2a78651593323e8b9627c39918d949a33497b70f - but as far as I can see it also still uses the wrong terminology s/AGCH/PCH.

Its the case that we have to use an ericsson proprietary way to handle this. Unfortunately the code seems to be a bit out of place now. Maybe we should add a SAPI PCU_IF_SAPI_PCH_ERIC or so that handles this. I am not entirely sure.
