Description (partial)

When a call comes through a bearer channel , let's say 17 , the output of ?show ip interface brief ? shows  Status--> UP and Protocol
--> DOWN  , but in ISR G2 , we see both as UP and UP.
Please check below the comparison:
On ISR 4K:
Serial0/1/0:17         unassigned      YES unset  up                    down
On ISR G2:
Serial0/0/0:17           unassigned      YES unset  up                    up

Note: This is an ISR 4K specific problem

ISR 4K series router
