Also,<br>they required BTS+BSC to run next to the PCU.<br><br>The new PCU_Tests_RAW introduced in this patch are the exact opposite:<br>* they test the PCU alone (attach to PCUIF and Gb interface)<br>* they don't require BTS or BSC to run<br>* they don't use NS + BSSGP emulation but raw NS/BSSGP frames to<br> test the very NS/BSSGP implementation inside of OsmoPCU.<br><br>Change-Id: I7ad76b96974cf0a686ad0f00ccd09d1a9df8b4d5<br>---<br>M pcu/PCU_Tests.cfg<br>A pcu/PCU_Tests_RAW.ttcn<br>M pcu/gen_links.sh<br>3 files changed, 372 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/osmo-ttcn3-hacks refs/changes/84/12984/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/pcu/PCU_Tests.cfg b/pcu/PCU_Tests.cfg</span><br><span>index 5975290..17d5448 100644</span><br><span>--- a/pcu/PCU_Tests.cfg</span><br><span>+++ b/pcu/PCU_Tests.cfg</span><br><span>@@ -33,6 +33,7 @@</span><br><span> </span><br><span> [TESTPORT_PARAMETERS]</span><br><span> *.*.udpReuseAddress := "yes";</span><br><span style="color: hsl(120, 100%, 40%);">+*.PCU.socket_type := "SEQPACKET"</span><br><span> </span><br><span> [MAIN_CONTROLLER]</span><br><span> </span><br><span>diff --git a/pcu/PCU_Tests_RAW.ttcn b/pcu/PCU_Tests_RAW.ttcn</span><br><span>new file mode 100644</span><br><span>index 0000000..50d9d0e</span><br><span>--- /dev/null</span><br><span>+++ b/pcu/PCU_Tests_RAW.ttcn</span><br><span>@@ -0,0 +1,370 @@</span><br><span style="color: hsl(120, 100%, 40%);">+module PCU_Tests_RAW {</span><br><span style="color: hsl(120, 100%, 40%);">+</span><br><span style="color: hsl(120, 100%, 40%);">+/* "RAW" PCU tests: Talk directly to the PCU socket of OsmoPCU on the one hand side (emulating</span><br><span style="color: hsl(120, 100%, 40%);">+ the BTS/BSC side PCU socket server) and the Gb interface on the other hand side.
