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 ~N On Wed, Dec 28, 2016 at 03:34:27PM +0300, Родион Гадыршин wrote: > Hello, list. > > I have umtrx v2.1 and I have already built GSM and GPRS components.

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.
