We have many 7200vxr's with DS3 interfaces. Though I am not sure this would be a interface problem. When you say that your provider sees errors on the circuit, where are they putting equipment? Is it an in-line test or an end to end test? Also, how is the DS3 being delivered? Be sure to check your coax and connectors. If you are only getting 5mbps on the line, I would ask your provider to come out and show you on a test set an end to end sweep from Point A to Point B. If you are getting data, and do not have AIS - I would assume somewhere something isn't up to spec physically. Feel free to ping me off list Adam. //warren Warren Bailey GCI Communication Corp.

Does anyone else use a cisco 7200 with a DS3 interface that we might be able to speak with? Please hit me off list Thank you, Adam 801.971.1856
