falconia has submitted this change. ( https://gerrit.osmocom.org/c/libosmo-abis/+/39621?usp=email ) Change subject: tests: add unit tests for osmo_rtp2trau() ...................................................................... tests: add unit tests for osmo_rtp2trau() The suite of unit tests added in this patch exercises osmo_rtp2trau() followed by osmo_trau_frame_encode() for the following combinations of speech codec and TRAU frame type: * FR and EFR codecs, TRAU-16k frames, both DL and UL * HRv1 codec, TRAU-8k format, DL only (RTP->TRAU conversion for HRv1 does not currenty support TRAU-UL output.) All output TRAU frames contained in rtp2trau_*.ok files (expected output for unit tests) have been manually checked with Themyscira decoding utilities trau-parse-hex (16k) and trau-hr-dump-hex (8k); these utilities in turn were developed to analyze TRAU frame streams captured from historical BTS and TRAU equipment, hence the chain of truth reference comparison is traceable to pre-existing historical hardware implementations of GSM 08.60 and 08.61 specs.

[S] Change in libosmocore[master]: codec: add some constant frames for HR and EFR
by falconia 27 Feb '25

27 Feb '25

falconia has submitted this change. ( https://gerrit.osmocom.org/c/libosmocore/+/39636?usp=email ) Change subject: codec: add some constant frames for HR and EFR ...................................................................... codec: add some constant frames for HR and EFR With all 3 classic GSM codecs (FR, HR and EFR) sometimes a need arises for a constant fill frame, to be inserted when no good speech frame is available. For GSM-FR codec the substitution/muting spec (GSM 06.11) explicitly defines a silence frame for this purpose, but no such officially defined fill frames exist for HR or EFR. Those newer codecs do, however, have homing frames that all decoders are required to implement, and there is an unofficial silence frame for GSM-HR, observed as the output from the official encoder fed with all-zeros input. Add these 3 constant frames (HR silence, HR homing, EFR homing) to libosmocodec in order to make them easily usable in any application that may need them, including applications that cannot have ThemWi codec libraries as dependencies.

[S] Change in libosmo-sigtran[master]: Use default_layer_manager for all ASPs in SCTP-mode=client & m3ua-mod...
by pespin 27 Feb '25

27 Feb '25

pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmo-sigtran/+/39637?usp=email ) Change subject: Use default_layer_manager for all ASPs in SCTP-mode=client & m3ua-mode=ASP ...................................................................... Use default_layer_manager for all ASPs in SCTP-mode=client & m3ua-mode=ASP With previous behavior, only first ASP configured as SCTPmode=client and m3ua-mode=ASP in osmo_sccp_simple_client_on_ss7_id() would be applied the default_layer_manager. AS a result, if a client app (eg. osmo-bsc) would manually configure 1 ASP with 2 ASPs (and leave it to dynamic RKM to setup everything at osmo-stp), it would fail, since the default LM FSM (in charge of waiting for NTFY and then sending REQ_REG) would only be applied to the first ASP. So one would see 1st ASP doing ASPUP+REG_REQ+ASPAC correctly, but the second one would do ASPUP+ASPAC directly, which would be refused by osmo-stp since it had no routing context configured for that ASP/AS.
