Hi people, We have configured and working quadBRI in NT and TE mode. In TE part have pri_cpe_ptmp signalling and quadBRI leds are green. When asterisk in in verbose >=2 said "D-Channel on span 3 down" and immediately "D-Channel on span 3 up" maybe something is wrong, because in two hours the asterisk an quadBRI down responds to make calls or pickup. The system is running and we need reboot the system to reset the quadBRI because don?t respond with unload and load modules. We are using RC20. If we put the pri debug on nothings appear. We need put the system stable, what can I do?, what information you need to help us?, very thanks. Regards, Pedro
