* 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.
