A few requests contain known<br>'*#100#' request code, others are intentionally wrong.<br><br>Finally, we expect that each received response shall correspond<br>to its request and shall be sent back on a proper transaction.<br><br>Change-Id: Ifa3cd1aeeb34ccf5864f78b76a88aaa6d5e51839<br>---<br>M msc/MSC_Tests.ttcn<br>1 file changed, 136 insertions(+), 0 deletions(-)<br><br></pre><pre
