I am having a problem with a new PRI turn-up on dahdi 2.5.0 and asterisk 1.8.5 that I have not seen before. The PRI is setup as B8ZS, ESF and the span shows up and ok. This PRI is merely a crossover T1 going into an old DC0 class 5 switch.
I am getting the following errors over and over again [Aug 16 10:26:10] NOTICE[8002]: chan_dahdi.c:3043 my_handle_dchan_exception: PRI got event: HDLC Bad FCS (8) on D-channel of span 1 [Aug 16 10:26:10] NOTICE[8002]: chan_dahdi.c:3043 my_handle_dchan_exception: PRI got event: HDLC Abort (6) on D-channel of span 1 I am also showing CRC4 errors on span as well. # asterisk -rx "dahdi show status" Description Alarms IRQ bpviol CRC4 Fra Codi Options LBO T2XXP (PCI) Card 0 Span 1 OK 1 0 2938622 ESF B8ZS 0 db (CSU)/0-133 feet (DSX-1) I am leaning towards a misconfiguration on the span on the switch side but here is my setup. Can anyone point me in the right direction? # dahdi_hardware pci:0000:06:08.0 wct4xxp+ d161:1220 Wildcard TE220 (5th Gen) /etc/dahdi/system.conf # Span 1: TE2/0/1 "T2XXP (PCI) Card 0 Span 1" (MASTER) B8ZS/ESF ClockSource span=1,1,0,esf,b8zs # termtype: unknown bchan=1-23 dchan=24 echocanceller=mg2,1-23 /etc/asterisk/chan_dahdi [channels] language=en context=Incoming-Pri switchtype=dms100 signalling=pri_cpe group=1 channel => 1-23 Thanks, Eric Merkel -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
