Fwd: hdlc and kernel 2.4.26
Hello, I contacted Krzysztof Halasa, the maintainer of the current sethdlc code. This is the response he gave me. Of course, I have this working now. Still some minor configuration to do, but It does work, and the connections to the internet are _much_ faster than when I went through the adtran... I would highly recommend to anyone with a fractionated T1, with data and voice channels to

zaptel ppp HDLC Receiver Overrun messages
I have a pair of sites tied together with a T1 line running zaptel PPP on either end. The system works, but I keep getting these messages in the kernel logs, and users are reporting connection problems (TCP timeouts, and hangs) especially under high usage. --snip-- HDLC Receiver overrun on channel WCT1/0/1 (master=WCT1/0/1) HDLC Receiver overrun on channel WCT1/0/1 (master=WCT1/0/1) HDLC

HDLC bad FCS
I have 2 servers, configured identically. Each has a TE405P and 2 PRIs. One server was experiencing crackly audio on one circuit, accompanied by HDLC bad FCS messages. The telco recabled and moved me to another port on the DMS-100. The audio is better, but there are still bad FCS problems on the span. I have moved the PRI in question to the other server, and the problem does indeed move with the

I've read as much as I can on this error and still can't seem to figure out what's causing this error: Jun 23 20:54:58 NOTICE[7483]: chan_zap.c:7395 pri_dchannel: PRI got event: HDLC Abort (6) on Primary D-channel of span 1 Jun 23 20:55:03 NOTICE[7483]: chan_zap.c:7395 pri_dchannel: PRI got event: HDLC Abort (6) on Primary D-channel of span 1 Jun 23 20:55:03 NOTICE[7483]:

HDLC/Zaptel/Kernel 2.6.11(.9)
All, I'm having a heck of a time getting hdlc to work on kernel 2.6.11.9 .. I compiled hdlc, hdlc_gen, hdlc_cisco, hdlc_raw, into the kernel (note into, and not 'modules'). System comes up, I configured zaptel.conf span=1,0,0,esf,b8zs nethdlc=1-24 modprobe wct4xxp ztcfg sethdlc hdlc0 cisco ifconfig hdlc0 up All of this works fine, believe it or not. I have a T1 cross plugged

Suddenly "HDLC Bad FCS (8)" errors on ISDN-PRI, changed nothing
Hi fellow asterisk users, I am running Asterisk 1.4.29 with an Digium TE121 card (wcte12xp kernel module) an approx. 100 snom320. The whole installation is running without issues since 5 months. Without having changed anything on the asterisk server for at least 2 months, i noticed "clicking sounds" at external calls over the PRI. Asterisk constantly throws the following messages: ...

T100P HDLC configuration
All, I am trying to configure hdlc support on T100P Digium card - everything seems ok... but it just does not work at all. I was able to compile all drivers, the light on the card becomes green when I plug T1 link.... but I even can't ping default router IP... there is no data coming back to me, so I am confused completely now. Also I tried both protocols - raw hdlc and cisco hdlc. The

Hi, After upgrading to DAHDI 2.4.0 from Zaptel, I noticed a lot of HDLC errors on my console: [Nov 27 01:15:09] NOTICE[2743] chan_dahdi.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1 [Nov 27 01:15:09] NOTICE[2743] chan_dahdi.c: PRI got event: HDLC Abort (6) on Primary D-channel of span 1 These errors prevented calls from being made and received on my PRI spans.

HDLC on T1
I have a new client who is about to order an Integrated PRI T1--eight voice channels and the remainder data. He's not sure whether Qwest will provide a router to split the voice and data. I remember we had a lot of trouble with HDLC in Linux kernels past 2.4.19. Have those problems been fixed in the 2.6 kernel? Will I be able to split the voice and data channels using zaptel?

HDLC Bad FCS (8) HDLC Abort on TE410P
Dear All, we have installed a TE410P card on a Dell Poweredge 1750 running a slackware 10 with 2.4.26 Kernel. Then we have made two loops on the card and we have configurated all the 120 channels. Our goals was to perform some stess tests even if in this scenario we used the same box as generator and target. The stress test comprised to generate up to 60 calls at the same time by placing a file

PRI got event: HDLC Abort (6) on Primary D-channel of span 1
I receive this error on the asterisk console and it is pretty much ALWAYS coming up. Sometimes there will be a break where it does not display. We had our PRI provider test the lines and they claim that there is no signalling problem. It doesn't matter if there are no calls or if there are 10 calls in progress the error is still displayed. I also get an annoying popping or clicking sound

HDLC
There were a number of messages about using a digium card as a data t1 (router) kind of thing. Is there a howto out there or a status that I can see whether this is feasible or not? Or is it feasible but very difficult? -- respectfully, Joseph - (606) 477-2355 x140 ------=============

B410P: DAHDI BRI PTMP HDLC Abort (6) on Primary D-channel of span 1 (TEI Errors)
Hi all, So, we reverted the LibPRI version and tested it, and then tried with the latest version of everything. Still no changes. The BRI line is in PTMP. If we set the configs to PTMP in the genconf_parameters and try it, we get the following: [Jan 21 17:32:20] ERROR[20341]: chan_dahdi.c:12645 dahdi_pri_error: Unable to receive TEI from network!

HDLC errors
I'm running Asterisk 1.2.26.1 svn rev 79171 on Trixbox 2.2. libpri 1.2.7 and zaptel 1.2.22.1. The hardware is a HP dl360 single cpu with a TE220B. The system load is below 0.10. I moved the server into production, with one PRI, on Friday. On that day we handled a couple thousand calls and I only saw one HDLC abort message. On Saturday half the calls and two abort messages an hour
