In particular, the test suite<br>verifies the following scenarios:<br><br> - RSL -> BSSAP:<br> - 16 MO messages on FACCH/F with SAPI0,<br> - 16 MO messages on SACCH/F with SAPI3;<br> - BSSAP -> RSL:<br> - 16 MT messages on FACCH/F with SAPI0,<br> - 16 MT messages on SACCH/F with SAPI3.<br><br>Change-Id: Ica69ae95b47a67ba99ba9cc36629b6bd210d11e4<br>Related: OS#3716<br>---<br>M bsc/BSC_Tests.ttcn<br>M bsc/expected-results.xml<br>2 files changed, 60 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace;
