3 | 12 | laforge | [[OsmoBSC:]] is an implementation of a GSM BSC (Base Station Controller), i.e. it offers |
4 | * an A-bis interface towards the BTSs |
||
5 | * an A-over-IP (AoIP) interface towards an MSC (e.g. [[OsmoMSC:]]). |

||
8 | |||
9 | Until 2017, we used to have an @osmo-bsc@ part of the old @openbsc.git@ repository which implemented a smaller sub-set of the BSC functionality with an [[cellular-infrastructure:SCCPLite]] based A interface. This legacy program is now called @osmo-bsc-sccplite@ and continues to be available for legacy users. However, it is not actively developed anymore. |
