Urgent Need Help in SMPP

Please can any one tell me that how can i extract SMPP code from kannel.  I want 
to develop my own application using SMPP i want this because of  following 
reasons:
1. In existing kannel i am unable to give high priority to the massages  already 
in queue i have also used (0-3) priority but still its behavior  is same.
2. Also existing kannel route the massage to any SMSC in multiple SMSC  
environment. I have tried to use "denied-smsc-id" but still when one  SMSC goes 
down (means not responding but not alive )  kannel route  message to the other 
SMSC.

So that is why i want to extract SMPP module from kannel so guide me how  can i 
do this i am new on kannel source code. Also if you have any  other solution 
then tell me but reply as soon as possible.

Regards,
