Hi Kumar
Can you post output of : sh isdn status
As you told your layer 1 is up & you are getting TEI_ASSIGNED , Which indicates that Layer 2 frame not exchange with SP switch.
May be you can check that you are getting some error on the controller or use debug to verify the issue.
Please refer the below link : http://www.cisco.com/en/US/tech/tk713/tk628/technologies_tech_note09186a00801509d7.shtml
