Cisco HWIC-1DSU-T1 Config for MPLS

Hello,

I am fairly new(b) to configuring Cisco routers for MPLS. My scenario is this: We just establish a MPLS network with Earthlink a few months ago between two locations with four bonded T1's. At the time it was decided to have Eathlink provide the router for that connection and all is working well there.

We recently decided to add another location to our MPLS network however this time it was decided that we would provide the router for this location.

So we purchased a Cisco 1921 with a HWIC-1DSU-T1 card. For the configuration of the serial interface I have:

interface Serial0/0/0
 ip address 10.168.0.10 255.255.255.252
 encapsulation ppp
 no shutdown

When we connect to the circuit, I get nothing. The interface stays in a line protocol down
state.

Am I missing something on the configuration of this interface for MPLS?

Below is what the network looks like. Earthlink assigned the 10.168.0.8/30 subnet to this network. 10.168.0.9 being the provider edge router and 10.168.0.10 being the customer edge (our) router.

If there is a need to attach the whole config for this router I can.

Thanks in advance!!!
