<ul><li><strong>Status</strong> changed from <i>New</i> to <i>Feedback</i></li><li><strong>Assignee</strong> changed from <i>pespin</i> to <i>fixeria</i></li></ul><p>According to [1], SETSLOT is being sent to osmo-trx when a dyn ts channel is modified (PDCH ACT/DEACT).</p>
<p>Assigning to <a class="user active" href="https://projects.osmocom.org/users/67">fixeria</a> since he was the initial one having concerns about this perhaps being broken, so he can validate everything's fine.</p>

<ul><li><strong>Status</strong> changed from <i>Feedback</i> to <i>Resolved</i></li><li><strong>% Done</strong> changed from <i>0</i> to <i>100</i></li></ul><p>I confirm that osmo-bts-trx does send 'SETSLOT' when switching a dynamic time-slot.</p>
