neels gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, laforge, pespin, fixeria, dexter, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bsc/+/24374 to look at the new patch set (#21). Change subject: implement Channel Mode Modify to VAMOS mode ...................................................................... implement Channel Mode Modify to VAMOS mode Put a (primary) lchan in VAMOS speech mode. This is not yet about activating shadow lchans, this merely puts any lchan in a VAMOS capable channel- and speech mode. Protocol: In RR Channel Mode Modify, send a spec conforming VAMOS channel mode as well as an Extended TSC Set, wich adds the TSC Set to the training sequence code value. In RSL MODE MODIFY, send Osmocom specific extensions to indicate the TSC Set and TSC, as well as the VAMOS channel mode; only to OsmoBTS type cells. - Set the Channel Mode's Channel Rate to Osmocom specific RSL_CMOD_CRT_OSMO_TCH_VAMOS_Bm / RSL_CMOD_CRT_OSMO_TCH_VAMOS_Lm - Add the Osmocom specific Training Sequence IE containing both TSC Set and TSC. (These are documented in the Abis manual.) Implementation: The internal API to request a Mode Modify is lchan_modify(info). Add to this info the 'vamos' bool, set to true when the modification should put the lchan in VAMOS channel mode or not. When info.vamos == true, make sure the channel mode value is a VAMOS one: in the copy of info->ch_mode_rate at lchan->modify.ch_mode_rate, convert to the right VAMOS/non-VAMOS equivalent channel mode. When the modification is through, set lchan->vamos.enabled appropriately. This patch also builds on Ic665125255d7354f5499d10dda1dd866ab243d24 'allow explixit TSC Set and TSC on chan activ / modif / assignment' placing tsc_set and tsc values in the TSC related IEs.
