Patch Set 1: (1 comment) https://gerrit.osmocom.org/c/osmo-bts/+/25296/1/src/osmo-bts-trx/sched_lchan_tchf.c File src/osmo-bts-trx/sched_lchan_tchf.c: https://gerrit.osmocom.org/c/osmo-bts/+/25296/1/src/osmo-bts-trx/sched_lchan_tchf.c@470 PS1, Line 470: LOGL1SB(DL1P, LOGL_NOTICE, l1ts, br, "Codec (FT = %d) " > Shouldn't we keep sending with the older type until we can change it? I'd expect the received to acc […] I don't understand this code in general, even the current one. We as an RTP capable BTS cannot influence at all what codec mode is transmitted in downlink. We may receive a CMR from the MS, and we pass that on in the CMR header of the uplink RTP frames. It is up to the sender/encoder of that RTP to then start generating the proper requested codec mode and start sending that. The BTS is not generating/encoding the AMR, it merely relays AMR frames from Abis/RTP to Um and vice-versa. On the Um interface we only have either CMR or CMI [depending on FN] and we can only signal a subset of up to four codec modes from the set. On the RTP side every frame has CMI (== FT) and CMR, and we can express any of the AMR modes. Can anyone explain to me what is happening here in this code and why? -- To view, visit https://gerrit.osmocom.org/c/osmo-bts/+/25296 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Change-Id: I94a934a6b3b397b4cd0e9da3577325de58814335 Gerrit-Change-Number: 25296 Gerrit-PatchSet: 1 Gerrit-Owner: dexter <pmaier at sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: fixeria <vyanitskiy at sysmocom.de> Gerrit-Reviewer: laforge <laforge at osmocom.org> Gerrit-Reviewer: pespin <pespin at sysmocom.de> Gerrit-Comment-Date: Tue, 31 Aug 2021 19:35:02 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: pespin <pespin at sysmocom.de> Gerrit-MessageType: comment -------------- next part -------------- An HTML attachment was scrubbed...
