csd_bs_list_to_bearer_cap(): properly initialize bcap fields Currently this function fails to initialize all bcap fields properly, so the resulting CC Setup message generated by osmo-msc has some fields set to reserved/invalid values. With these changes I am able to establish a data call on TCH/F9.6: * cap->{mode,coding}: assign default values explicitly; * cap->radio: value 0 is reserved, set GSM48_BCAP_RRQ_FR_ONLY; * cap->data.sig_access: value 0 is reserved, set GSM48_BCAP_SA_I440_I450; * cap->data.transp: this is not a bool, set GSM48_BCAP_TR_{TRANSP,RLP}; * cap->data.{nr_{data,stop}_bits,parity}: set 8N1 by default; * cap->data.modem_type: explicitly assign default value; * cap->data.interm_rate: value 0 is reserved, set GSM48_BCAP_IR_{8k,16k}. The related libosmocore.git patch additionally fixes encoding of the "Connection element (octet 6c)", so that bcap->data.transp is used.

OsmoMSC originated from the OsmoNITB project, which started as a minimalistic all-in-one implementation of the GSM Network. In 2017, OsmoNITB had reached maturity and diversity (including M3UA SIGTRAN and 3G support in the form of IuCS and IuPS interfaces) that naturally lead to a separation of the all-in-one approach to fully independent separate programs as in typical GSM networks.
OsmoMSC was one of the parts split off from the old openbsc.git.
