Hello Siddharta,

the first basic check is to use

sh interface serial x/y

command and to see if there are errors of any type.

Repeat the commands every 5 minutes to see if error counters are incrementing.

Here it is a link for serial lines troubleshooting

http://www.cisco.com/en/US/docs/internetworking/troubleshooting/guide/tr1915.html

possibly compare the outputs of routers at both ends of the link.

Hope to help
