Cisco Multilink, only 3 of 4 interfaces have L2 connectivity.
I have 4 point to point T1 circuits connecting a branch office to my data center. I am trying to combine them using ppp multilink. All interfaces have layer 1 connectivity but 1 of the 4 interfaces will not maintain a layer 2 connection. Data center router is a Cisco 7206. Branch office router is a 2620.
Here is the config at the datacenter:

Yep, when I removed multi-link and just set each end up with a IP address in the same subnet I still have issues...kind of.
At the data center serial 2/0/11:0 still show status of up/down as does s1/1:1 at the branch office. Doing a loopback local on s1/1:1 at the remote router seems to have no effect. Not sure if this is the correct way to loop or not. I have contacted the NOC at my datacenter as they handle our circuit contracts as well as extensions to our colocated racks.

It looks like you've got an external CSU at the datacenter and an internal CSU at the branch. Can you post the output of a "show controller" for the four lines.
Have you tried moving the T1's to different interfaces to see if the problem moves?

I guess that you could say the CSU at the data center is external. The circuits are delivered to the NOC via an OC12 from the carrier. From there, there is a "virtual cross connect" in a Cisco 15454 that they deliver to us via a DS3. This is all according the NOC staff at the data center where we are colocated.
Anyway, here is the output of show controllers at the remote side. Do you want it for the Data Center as well?

So I talked with the NOC at my data center. They helped a bit by having the carrier test the circuit and offered some config ideas, but I was unable to get the circuit working. I went to the branch office and swapped the cables on serial 1/0:0 and serial 1/1:1. It is still s1/1:1 that is showing status of up/down, which means the problem stays with the interface and not with the circuit attached to it. Could I have bad hardware? I am using a PRI 2CTI-CSU add in module on a 2600 series router.
I would swap the cables for serial 1/0 and 1/1 at the remote site. Since they (appear) to be terminating on the same type of equipment.
If the problem moves with the cable, you know it's not the router. If the problem stays with the interface, you know it's something on the router.

As I mentioned in my previous comment, the cables have been swapped at the remote site. The problem stayed with the interface so it is either a hardware or configuration problem and not a circuit problem. I'm not sure where to go from here though.
Sorry. When configs get posted inline with comments, it's easy to miss something. I suggest using the "code" feature when posting configs and long output.
That said, you're right. It's either a port problem or a config problem. Or it could be a failure in the slot. I would try moving the controllers between 1/0 and 1/1. If it's the physical port or controller, the problem will move. If the problem doesn't move, it's either the config or the slot.

Doesn't look like the controllers can be moved. They are part of a two port add in module.

Without multi-link configured, do you still have the same issue with Serial2/0/11:0 ?
I'm guessing that you do. In which case I would either loop one end and check the status or get the telco involved.
