h1. OsmoBSC 

 [[OsmoBSC:]] is what we call the _flavor_ of OpenBSC that acts like a classic GSM BSC, i.e. it offers 
 * an A-bis interface towards the BTSs 
 * an A interface towards an external MSC 

 No other functionality is included.    It is thus primarily suitable for operaters who want to integrate with their existing MSC (and other core network).    If you want to roun your own GSM network without dependency to other classic GSM network elements, try [[OsmoNITB:]] instead.
