Re: [asterisk-users] Problems Connecting Two Asterisk Installs Via ISDN PRI Cards
Okay. I ordered a commercially made T1 crossover cable, connected all of the cables and rebooted both computers. I no longer get the 'Got S-frame while link down' or 'HDLC Bad FCS' errors. However, I still receive the series of 'Detected alarm on channel NN: Red Alarm' and 'Unable to disable echo cancellation on channel NN'. Followed by the alarms clearing. At this point I am confident that the cabling is not the problem. I have included my zaptel and zapata conf files again below. Is there a way to make the second TE120P card pass on the timing received from the first? (rather than using software timing for the pri_net signalling) The errors all seem to be about echo cancellation... What do I need to do to force asterisk to never disable echo cancellation? Thanks again for all of the help. Even though we have not found a solution yet I appreciate the help - and am still confident we will succeed! -Brian Machine1 = zaptel.conf --- defaultzone=us loadzone=us span=1,1,0,esf,b8zs bchan=1-23 dchan=24 span=2,0,0,esf,b8zs bchan=25-47 dchan=48 zapata.conf --- [trunkgroups] [channels] group=1 context=fromtelco signalling=pri_cpe switchtype=national channel=1-23 group=1 context=frommachine2 signalling=pri_net switchtype=national channel=25-47 Machine2 = zaptel.conf --- defaultzone=us loadzone=us span=1,1,0,esf,b8zs bchan=1-23 dchan=24 zapata.conf --- [trunkgroups] [channels] group=1 context=frommachine1 signalling=pri_cpe switchtype=national channel=1-23 ___ Sign up now for AstriCon 2007!

I may have missed it in a previous message if you mentioned it. I've got a setup where I have a 2 port PRI on our main server. One port goes to telco and the other goes to a test lab asterisk system. Sometimes, I have noticed that I screw the test system up so bad that I have to reboot the main system, and unplug the PRI before doing so. It seems like alarms get hung up or something. This is using a 2 port Sangome card and a 1 port Sangoma card. I can't remember if I have this problem using the 1 port Digium.

Check out the images I've just placed at http://www.asteriskdocs.org/cables/ to check to see if your T1 crossover is wired correctly. For a T1 cross-over cable, one end of the cable should match the Straight diagram and the other end should look like the T1 crossover diagram.

Re: [asterisk-users] Problems Connecting Two Asterisk Installs Via ISDN PRI Cards
Brian, I hope this helps, it is slightly different from what you have setup. Here is what I used to connect my asterisk server to our Norstar Meridian. The Norstar T1 was setup as pri_cpe with the 24th channel as D. Check out this webpage for making a T1 crossover cable : http://www.voip-info.org/wiki/view/crossover+T1+cable You should also try making/obtaining a T1 loopback adapter and test both cards. http://www.adtran.com/adtranpx/Doc/0/FMPI9MBKGJBH39S8038BE81ID8/ CU-2abf1b83844b11d78ff20c045003.html Just curious, which cards are you using? On zapata.conf below in the norstar section, I set my timing source to be 0. This is because I am getting timing from the first span. If you are only connecting the two machines together and neither one has other T1's going to a telco. Then just set one of them as primary (1) and the other as do not use (0). span=(spannum),(timing),(LBO),(framing),(coding) Zaptel.conf -- loadzone=us defaultzone=us #PRI to TimeWarner span=1,1,0,esf,b8zs bchan=1-23 dchan=24 #PRI to Norstar Meridian span=2,0,0,esf,b8zs bchan=25-47 dchan=48 #TDM800 Card fxoks=49-52 fxsks=53-56 Zaptel.conf -- [channels] ;Time Warner T1 (SPAN 1) context=tw-pri-in group=2 ;Echo Cancel turns on the Octastic Hardware Canceller on the card echocancel=yes ; Tell Asterisk to reset the channels every two hours resetinterval = 7200 ; Relax DTMF relaxdtmf=yes rxgain=0.0 txgain=0.0 signalling = pri_cpe switchtype = national channel = 1-23 ;Norstar T1 (SPAN 2) context=norstar group=3 signalling = pri_net channel = 25-47 Forrest Beck [EMAIL PROTECTED] www.shift8.biz On Sep 21, 2007, at 9:31 AM, Brian Alexander wrote: On 9/20/07, Jared Smith [EMAIL PROTECTED] wrote: I'd look at your wiring, as an HDLC error like that is usually an indication of some type of a problem at the physical layer.
