The FSMs terminate once initialization is done. This could and should probably be further extended to having the BSC-side per-MO FSMs running persistently and tracking the state of their counterparts in the BTS. I also committed the OM2000 MO initialization sequences messace sequence charts to osmo-gsm-manuals, in case you're curious to see how code corresponds the protocol messages. > Do you think this is also doable for the Nokia Site BTS series? Of course, why not? I've never looked too deep at the Nokia OML dialect/flavor though. I think for most users the more important part would be the generic one for the TS 12.21 managed objects, which then helps for nanoBTS, OsmoBTS and BS-11. > Because if you think its doable, based on your work I a would like to > try and implement this for Nokia support too, as even between > different Site versions (InSite, Metro and UltraStie), there are some > differences in the OML initialization (especially in the timing of it) > which is now handled by hard coded values, instead of a proper state > machine. Sure, I think it would make a lot of sense, technically. I'm just not sure how many OpenBSC useres with Nokia BTS are out there. But that shouldn't keep you from doing it, if you feel an urge to do so :) -- - Harald Welte <laforge at gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
