OK, sounds good. But what are your objectives, what are you seeking to accomplish? Alina said earlier that you were seeking to connect the Siemens BSC to OsmoMSC; Harald replied that this task would be quite difficult, and I concur - but of course difficult != impossible, everything is possible with enough effort - but what is the real goal? Why is the alternative solution of connecting the Siemens BTS to OsmoBSC not acceptable? The only reason I can think of is perhaps you are someone like me, someone who absolutely loves and adores retro-telecom technologies and old telco gear of all kinds, and wishes to keep the real Siemens BSC and its TRAU as a matter of philosophical principle. If this situation indeed holds, please let me know! I have to explicitly ask this question because motivations like mine are extremely rare in this community, most other participants around here seem to approach from a commercial PoV, and their mindset tends to be totally different from mine. > - there is also a Siemens/NEC NodeB 440 that should be ok, but we don't > a functional RNC (the Iub interface is a STM1 optical) This part is outside my area of knowledge: I focus on 2G only, no 3G. In any case, I am still interested in hearing what is your motivation for getting the Siemens BSC (with TRAU) working with Osmocom CNI, and not just the BTS part - if your motivation is akin to mine (philosophically principled retronetworking), then maybe we can be friends! Sincerely, Mychaela
