Let us say that one 10 GE is connected to your ISP and the other 10 GE is connected to your back bone, GSR 12406 has a distributed forwarding architecture, so technically forwarding traffic between the two 10 GEs should not pass through the backplane, that is why I expect to have a 10 Gbps throuput between outside and inside, but not sure :)
The lookups are done on the linecards (this is what is distributed), but the packet still has to traverse the fabric as far as I remember. There is no connection on the linecard to shortcut the fabric for intra-linecard forwarding.
