Hello,<br><br>On a 4 BRI Euro-ISDN TE/PtmP production system (Asterisk 1.6.1.18, Dahdi 2.5.0, Libpri 1.4.12), I sudently got the console cluttered with messages like this:<br>PRI got event: HDLC Abort(6) on Primary D-Channel of span <foo><br>
<br>Then a flow of messages (twice per second) like this:<br>PRI got event: HDLC Overrun(7) on Primary D-Channel of span 2<br><br>Contrary to the first one which concerned all of the 4 spans, the second message type only concerned one span (span2).<br>
<br>So I stopped dahdi and asterisk, disabled span 2 and restarted everything.<br><br>No I see :<br>PRI span 1/0: Provisioned, Up, Active<br>PRI span 3/0: Provisioned, In Alarm, Up, Active<br>PRI span 4/0: Provisioned, Up, Active<br>
<br>With dahdi_tool main screen, I can exactly read<br>Alarms Span<br>OK HA8-0000<br>UNCONFIGURED HA8-0000<br>OK HA8-0000<br>RED HA8-0000<br>
<br>With "pri intensive debug span 3", I'm getting:<br><br>[Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: t203_expire<br>[Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c:<br>[Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > TEI: 75 State 7(Multi-frame established)<br>

<br>My questions are:<br><br>1. Am I correct observing span status provided by pri show spans and dahdi_tool, differ:<br>pri show spans says span 3 is in Alarm while dahdi_tool (and dahdi_scan) say that span 4 is in Alarm.<br>
<br>2. Which tool would give me the most accurate reason why a Dahdi span is in RED Alarm ?<br><br>3. Does the "pri intensive debug span 3" output above really belongs to span 3 and to an In Alarm span ?<br><br>
4. Suggestions ? Comments ?<br><br>Regards<br>
