Hi <name in Cyrillic>,
we currently have two types of dynamic channels, both of which are available
and working with osmo-bts-trx, with the limitation that OsmoNITB can't
transcode TCH/H <-> TCH/F.
See chapter 9.7 "Dynamic Timeslot Configuration" in the OsmoBSC User Manual
https://ftp.osmocom.org/docs/latest/osmobsc-usermanual.pdf
and the reference to https://osmocom.org/issues/1778 in 9.7.1.
Configuration suggestions are also found in that chapter.
BTW, about TCH/H_PDCH: https://osmocom.org/issues/1781

Hello, list.
I have umtrx v2.1 and I have already built GSM and GPRS components. Now I want to know
which way of configuring timeslots in osmobsc.cfn is the best. I want GPRS, calls and SMS
work.
My current configuration is:
timeslot 0
phys_chan_config CCCH+SDCCH4
hopping enabled 0
timeslot 1
phys_chan_config SDCCH8
hopping enabled 0
timeslot 2
phys_chan_config TCH/F
hopping enabled 0
timeslot 3
phys_chan_config TCH/F
hopping enabled 0
timeslot 4
phys_chan_config PDCH
hopping enabled 0
timeslot 5
phys_chan_config PDCH
hopping enabled 0
timeslot 6
phys_chan_config PDCH
hopping enabled 0
timeslot 7
phys_chan_config PDCH
hopping enabled 0
Is there a better way to configure? Maybe better use TCH/F_TCH/H_PDCH, but I have heard,
that TCH/F is currently not working in dynamic configurations - only TCH/H does. And there
is no only TCH/H_PDCH mode. So, could you please give me an advice?
