I have an old 7200, with a T3 terminating on it. From there, I have several Point to Point T1's through Qwest terminating at various remote locations. At one of my locations, I have a 2811, terminating 2 PTP T1's, and I am getting lots of errors on the T1's. This has caused some issues with data speeds and voice quality (VOIP). I suppose there could be some QOS issues, but I'm not sure. I have had Qwest test the lines, and they have run clean to the NIU. They are telling me there is probably a timing issue on the router config.
I have another 2811 configured the same way, and it has no problems. I'm not sure what I'm missing. Does anyone have any ideas?
Thanks
Jake
Here is some info from my environment:
