Does my Cisco 1760 Work?

I have a Cisco 1760 with T1 DSU installed. Both were working before we temporarily shut down for a relocation. Now we are connecting through a new T1 carrier (Verizon). They are trying to configure the router remotely through their serivce. They say the router is not "visible" from their side. I beleive that to be true since the line status on the serial device is "down" even though the DSU is connected to the T1 card by a known good streight trough CAT 5 drop cable.
Can I "test " the router and T1 module to verify it is working properly before they turn up the service.?

As it is now, the interface is disabled.

Enable it by:

Router#Conf t
Router(config)#int serial 0/0
Router(config-if)#no shutdown

That'll bring it up. If there are problems then we'll troubleshoot from there.

Can you provide the following?

Show run interface <connecting interface on your router>

Show interface <connecting interface on your router>

In most cases it should work fine with a move/carrier change, but it's partly dependent on your configuration.

Doing a loopback test tomorrow. Will collect the show data then.

Here is the output from the show commands. The serial interface is down and appears to stay down edven after issueing a No shutdown command. Being a novice at CLI and Cisco configuration I am at a loss as to how to proceed.
I would like to do a loopback test but cannot get the serial interface out of a down state.

CLI output follows:

Ok. For your provider to reach you, you'll also have to configure an IP address.

This is done like this:

Router(config-if)#ip address <ip address> <mask>

Address and mask should be provided to you by your ISP.

And you'll have to set passwords if you want the provider to configure the rest of the router for you.

Router(config)# enable secret <password>
Router(config)# line vty 0 4
Router(config-line)# password <password>
Router(config-line)# login
Router(config-line)# end

More info.
I ran a hard loopback test on 4 data patterns with no loss. That seems to indicatte to me that my equipment is good to go. Am I right?
