B400P crashes connection to telco

9 years 1 month ago #5472 by gelpg
Hi,

I have a B400P BRI card with point-to-point connection (signalling: bri_cpe) with this dmesg: http://pastebin.com/sXrRt1yM

When i restart asterisk server, the card cannot connect to the telco, the control led flashes red. If I unplug the cable between the ISDN nt and the card and wait 40 sec, the card can connect and works properly. The telco says the asterisk crashes the connection with the telco, when I let the NT reconnect, the card connects properly.


Do you have any idea how to solve this problem? Thanks for any help in advance.


Best regards,
Peter Gelencser

Hello,
What mode are you using? TE or NT? Base on the link of your dmesg information. It 's TE mode,but here you said it's NT connect. And I it was installed DAHDI driver,right? Did you use mISDN? If you want to use NT mode, I suggest you use mISDN instead of DAHDI ,mISDN fully supports NT mode. And we have manuals for that.
