</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">BTS_Tests: extend rach content tests with emergency call<br><br>The testcase tests if a CHANNEL REQUEST on the RACH leads to the correct<br>CHANNEL REQUIRED message on RSL level. When a MS is sending a CHANNEL<br>REQUEST to establish an emergency call, it uses a slightly different<br>layout for the request reference (RA). Lets add another similar testcase<br>(TC_rach_content_emerg) to cover the emergency call situation as well.<br><br>Change-Id: Ie5b7af3e93efaa6d0b412d3b1c77bc9514424f52<br>Related: OS#4549<br>---<br>M bts/BTS_Tests.ttcn<br>1 file changed, 35 insertions(+), 2 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace;
