Hello Vishal,
now is different the serial interface is down/down
before it was admin down/down.
A serial interface to be up/up needs to be connected to some device that makes leads to be up:
at the end of the show you see:
DCD down carrier
DSR down
CTS down
these are from L1 DCE
DTR and RTS are from the router serial interface
see the following from a router in production
sh int ser4/2
Serial4/2 is up, line protocol is up
[...]
446 carrier transitions DCD=up DSR=up DTR=up RTS=up CTS=up
if you are connecting two routers in back-to-back one has to provide clock:
use
clock rate 2000000
Hope to help

by default all ports are disabled.
you must go under the port and use the command "no shutdown"
then the port will be activated.
