I just spent the better part of three weeks working this out. A couple things to note, check the docs for your modem to make sure it's up to date and supports L2VPNs. You'll need the NSI interface configured on the CMTS, for the uBR7200 it's the following(if you're using dot1q). "cable l2-vpn-service xconnect nsi dot1q interface GigabitEthernet0/1", you'll need to change the actual interface being that you have a 10k. I'm in the process of deploying our first production customer now.

Rather than the config file, you can use TLS(Transparent LAN Service). It's much easier, just one line in the CMTS CLI.
cable dot1q-vc-map aaaa.aaaa.aaaa gigabitEthernet 0/1 1234 Customer
Where "aaaa.aaaa.aaaa" is the CM MAC, GigibitEthernet0/1 is the NSI, 1234 is the dot1q tag, and "Customer" is the customer ID/name.
OK, works with ubr7k but i have problems with ubr10k. There is some diference between both configurations?
Did you use the correct NSI interface on the 10k? Probably something like gi0/0/0?
Can you provide a little more detail about what isn't working.
