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

| * normal BSC tests, we here have to run *two* ConnHdlr and synchronize activity between them. |
| * |
| * We do this by adding some special-purpose ports between the main test component running the |
| * test case [lcls_]test_CT and the per-connection [LCLS_]MSC_ConnHdlr. |
