Hello,
I'm troubleshooting intallation of a fractional T1 circuit. I'm working with the worst ISP on earth they have pretty much told me I'm on my own. They are refusing to help so I'm trying to do some troubleshooting to either figure out the problem or have some evidence to put it back on them. I know this is a very simple config but please look for any errors. I'm getting "Serial0 is up, line protocol is down"
I'm not very familiar with loopback testing, any tips?

The following are some steps you can take to isolate the problem:
Perform DSU/CSU loopback tests. During local loopback, enter the show interface ser0 command. If the line protocol is shown as up, there might be a problem with the telephone company, or the remote router might be down.
Refer to the Hardware Installation Guide to confirm that your router is correctly installed, using the appropriate cables.
Connect the leased line to another port, if possible. If the connection comes up, there is a hardware failure on the Serial 0 port. Contact your Cisco reseller.
Please refer the following for more troubleshooting steps for leased line.
