I cannot ping the far end. The int s0/1/0 output shows up/up. The "sh service-module serial 0/1/0" output listed below shows the T1 is up with the correct framing, etc. The "sh diag" output below looks to be clean. Here is the output for "sh int s0/1/0" as well. I am totally at a loss here. Any ideas? Thank you
