CRC and INPUT ERROR at T3 leased line (about 30 CRC/ 700Kbps)

one side(branch) : cisco 7206vxr ( npe-400, pa-t3+)

other side(center) : cisco 7507(rsp4, vip4-50, pa-2t3+)

7206vxr and 7507 connected with 1 T3 leased line.

CRC and INPUT ERROR were generated at 7507 interface.

but in state of remote loopback to 7507 as following commands , no error

7206vxr (command: loopback network line)

7507(command: ping to interface itself - 10000 counts more)

7206vxr (command: show interface - no error)

7507(command: show interface - no error)

is it only the problem of leased line ? or pa-t3+ ?
