Hello,
We have configured new 2911 router with HWIC-2T with it.
However we are seeing serial interfaces up, but can hardly ping other end. Again we are seeing a lot of CRC errors on serial interface.
But if we connected same cable, with other old router 2811, it works fine. Confiuration is same on both the routers.

You should engage TAC on this for possible hardware replacement.
Note, for best results, use native T1 interface, not serial interfaces and converter.
