<ul></ul><p>comparing the failing run.2018-08-21_17-42-15 to the osmo dyn ts run.2018-08-21_17-52-16:</p>
<p>The succeeding <del>PCU</del> BTS log, on startup, says, for each dyn TS:<br /><pre>

</pre></p>
<p>The failing one lacks the "Activating PxxCH":<br /><pre>
20180821174235089 DOML <0001> oml.c:76 Sending PCU version report to BSC: 0.5.1.1-54af

<p>looking now why TCH/F_PDCH fails to activate PDTCH and PTCCH SAPIs...</p>

<ul></ul><p><a class="user active" href="https://osmocom.org/users/30187">pespin</a> , can you try an osmo-gsm-tester run of at least osmo-bts-trx for the suites that do</p>
<ul>
<li>osmocom style dyn ts</li>
<li>ipa style dyn ts</li>
<li>non-dyn ts</li>
</ul>
<p>with this patch plz: osmo-bts branch neels/trx_dyn_ipa</p>
<p>I hope that fixes it but I have no SDR hardware to test with...<br />thx!</p>
