problems with cisco 7200 and PA-T3

Just installed a cisco 7204vxr with a DS3 interface. we are not getting more than 5Mbits. show interface is not reporting any errors. the provider tech put a piece test equipment on the circuit and sees errors. 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
