<ul></ul><p>For some strange reason current wireshark seems to be completely unable to decode the OM2000, I don't have the time right now to start investigating that, sorry.

<ul></ul><p>Weird, decode works for me.</p>
<p>What I see is the TF Configuration Request and TF Configuration Request Ack, but then nothing from the TF after that.<br />So to me, that indicates either an E1 clock out of range, or the internal OCXO is still warming up.</p> Ericsson RBS 6xxx - Bug #4859: DUG20 + RUS 01 = Admin: Locked, Power offhttps://projects.osmocom.org/issues/4859?journal_id=202992020-11-11T09:35:26Zlaforge
<ul></ul><p>I just rebuilt wireshark master (33e63d19e5496c151bad69f65cdbc7cba2b4c211), and it does still exhibit the problem.</p>
<p>I also see the problem with the oldes build I have currently installed: v3.3.0rc0-1701-g4bea0e7c2ebf which I built on July 25th.</p> Ericsson RBS 6xxx - Bug #4859: DUG20 + RUS 01 = Admin: Locked, Power offhttps://projects.osmocom.org/issues/4859?journal_id=203002020-11-11T09:36:35Zlaforge

<p>for some strange reason I had gsm_abis_om2000 in the ~/.wireshark/disabled_protos list. No idea how that happened...</p> Ericsson RBS 6xxx - Bug #4859: DUG20 + RUS 01 = Admin: Locked, Power offhttps://projects.osmocom.org/issues/4859?journal_id=203472020-11-16T21:10:53Zkeith

<p>yes, that is very likely if you send unsupported features in the SI, or if you<br />send SI messages that are entirely unsupported. Howver, that shouldn't matter<br />in terms of phones seeing the BTS at all, and getting location updates etc. <br />going.</p> Ericsson RBS 6xxx - Bug #4859: DUG20 + RUS 01 = Admin: Locked, Power offhttps://projects.osmocom.org/issues/4859?journal_id=203812020-11-23T19:22:00Zkeith
<ul></ul><p>Ok Thanks, I should clarify there is still no RF transmission from the unit and no channels listed as active in osmo-bsc.</p>

<ul><li><strong>Status</strong> changed from <i>New</i> to <i>Closed</i></li></ul><p>Closing as: of little value apart from some documentation of first experiences with the RBS units.</p>
<p>Mostly it was due to E1 clock out of range, E1 clock was from a PCI card, using the iceE1 or a GPS unit fixed waiting forever at TF Configuration Request Ack</p>
