Let's make the<br>number of transceivers configurable (mp_transceiver_num), so it<br>can be adjusted depending on osmo-bts backend to be used.<br><br>Change-Id: Ic9dd49a2fc856de593b52b3ec0c559e0e15ca173<br>Related: OS#3155<br>---<br>M bts/BTS_Tests.ttcn<br>1 file changed, 31 insertions(+), 28 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace;
