Hello, 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: PRI got event: HDLC Abort(6) on Primary D-Channel of span <foo>
Then a flow of messages (twice per second) like this: PRI got event: HDLC Overrun(7) on Primary D-Channel of span 2 Contrary to the first one which concerned all of the 4 spans, the second message type only concerned one span (span2). So I stopped dahdi and asterisk, disabled span 2 and restarted everything. No I see : PRI span 1/0: Provisioned, Up, Active PRI span 3/0: Provisioned, In Alarm, Up, Active PRI span 4/0: Provisioned, Up, Active With dahdi_tool main screen, I can exactly read Alarms Span OK HA8-0000 UNCONFIGURED HA8-0000 OK HA8-0000 RED HA8-0000 With "pri intensive debug span 3", I'm getting: [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: t203_expire [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > TEI: 75 State 7(Multi-frame established) [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > V(A)=3, V(S)=3, V(R)=1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > K=1, RC=0, l3_initiated=0, reject_except=0, ack_pend=0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > T200_id=0, N200=3, T203_id=0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > [ 00 97 01 03 ] [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > Supervisory frame: [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > SAPI: 00 C/R: 0 EA: 0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > TEI: 075 EA: 1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > Zero: 0 S: 0 01: 1 [ RR (receive ready) ] [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > N(R): 001 P/F: 1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: > 0 bytes of data [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: -- Starting T200 timer [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < TEI: 75 State 8(Timer recovery) [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < V(A)=3, V(S)=3, V(R)=1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < K=1, RC=0, l3_initiated=0, reject_except=0, ack_pend=0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < T200_id=16384, N200=3, T203_id=0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < [ 02 97 01 07 ] [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < Supervisory frame: [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < SAPI: 00 C/R: 1 EA: 0 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < TEI: 075 EA: 1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < Zero: 0 S: 0 01: 1 [ RR (receive ready) ] [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < N(R): 003 P/F: 1 [Dec 6 10:32:58] VERBOSE[11461] chan_dahdi.c: < 0 bytes of data With dahdi_scan : dahdi_scan [1] active=yes alarms=OK description=HA8-0000 name=WCBRI/0/0 manufacturer=Digium devicetype=HA8-0000 location=PCI Bus 04 Slot 07 basechan=1 totchans=3 irq=20 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=B8ZS,AMI,HDB3 framing_opts=ESF,D4,CCS,CRC4 coding=AMI framing=CCS [2] active=yes alarms=UNCONFIGURED description=HA8-0000 name=WCBRI/0/1 manufacturer=Digium devicetype=HA8-0000 location=PCI Bus 04 Slot 07 basechan=4 totchans=3 irq=20 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=B8ZS,AMI,HDB3 framing_opts=ESF,D4,CCS,CRC4 coding= framing=CAS [3] active=yes alarms=OK description=HA8-0000 name=WCBRI/0/2 manufacturer=Digium devicetype=HA8-0000 location=PCI Bus 04 Slot 07 basechan=7 totchans=3 irq=20 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=B8ZS,AMI,HDB3 framing_opts=ESF,D4,CCS,CRC4 coding=AMI framing=CCS [4] active=yes alarms=RED description=HA8-0000 name=WCBRI/0/3 manufacturer=Digium devicetype=HA8-0000 location=PCI Bus 04 Slot 07 basechan=10 totchans=3 irq=20 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=B8ZS,AMI,HDB3 framing_opts=ESF,D4,CCS,CRC4 coding=AMI framing=CCS I'm trying to understand what is going on. My questions are: 1. Am I correct observing span status provided by pri show spans and dahdi_tool, differ: pri show spans says span 3 is in Alarm while dahdi_tool (and dahdi_scan) say that span 4 is in Alarm. 2. Which tool would give me the most accurate reason why a Dahdi span is in RED Alarm ? 3. Does the "pri intensive debug span 3" output above really belongs to span 3 and to an In Alarm span ? 4. Suggestions ? Comments ? Regards
