| 10 | * This test suite tests OsmoBSC while emulating both multiple BTS + MS as |
| 11 | * well as the MSC. See README for more details. |
| 12 | * |
| 13 | * There are test cases that run in so-called 'handler mode' and test cases |
| 14 | * that run directly on top of the BSSAP and RSL CodecPorts. The "handler mode" |
| 15 | * tests abstract the multiplexing/demultiplexing of multiple SCCP connections |
| 16 | * and/or RSL channels and are hence suitable for higher-level test cases, while |
| 17 | * the "raw" tests directly on top of the CodecPorts are more suitable for lower- |
| 18 | * level testing. |
