Hy everyone, I ‘been watching this blog and I found it very nice. And here it is a problem that I have. I have a 3300 ICP controller with a T1/E1 framer card installed in module 1, in port 1 it has a public link that works perfectly but in port 2 it has another public link but in this case it works for about 15 minutes after a manual reset, it’s led keep flashing in green and then it goes down. So in the error logs it appears like this… D channel module 1 port 2 down! So I need a little help in here, I’ll appreciate it a lot. thanks
